[package] boost/1.75.0: Build error for iOS on Mac #3992

andioz · 2020-12-25T17:04:37Z

I guess this is similar to my other issue for Android #3890, which is solved in the meantime. When building for iOS on Mac with optionshared=Falseonly, we get this error:

ERROR: 
	ConanException: boost/1.75.0 package_info(): Package require 'libiconv' not used in components requires

Shouldn't your compiler be apple-clang instead of clang?

If that doesn't change anything, I think the guesses at

conan-center-index/recipes/boost/all/conanfile.py

Lines 134 to 152 in c68b60a

    
           @property

               }.get(str(self.settings.compiler)) 
        
           @property

               # Nowide needs c++11 + swappable std::fstream

               }.get(str(self.settings.compiler))

are wrong.
This means that the recipe thinks your compiler supports the c++11 features required by some boost components.
Can you please post a complete output of a build?
An ls of the lib subfolder of the boost package folder would also be useful (to know what libraries were actually installed).

ok I have to double check with my colleague, may take some time. I'll come back on this

I started testing with a clean environment (I found CONAN_USER_HOME, thats a great help). I changed the compiler in my profile to apple-clang as you mentioned. The error still occurs.

I forgot to set the option boost:shared=False, but I guess this is irrelevant. Here are the details:

madebr · 2020-12-27T03:44:50Z

Thanks for the logs!

By taking a glance at them, it looks like the wild guess (also shown in #3992 (comment)) was too optimistic.
Can you try bumping "apple-clang": 12 to 13?

FYI: I'm working on a pr which has better error reporting #3999

andioz · 2020-12-27T09:47:29Z

I tried to change both guesses in conanfile.py from 12to 13, but the result is the same. I still see some messages in build output like BOOST_PRAGMA_MESSAGE("CAUTION: One or more C++11 features were found to be unavailable").

I cannot believe that apple-clang 12 (the current version) doesn't support all C++11 features? Maybe there is some other part in the configuration wrong. Even with disabling some parts by bumping min required version to 13 doesn't help.

I get the feeling we are hunting down the wrong way. Maybe the problem is simply something different. Where does this exception come from? ConanException: boost/1.75.0 package_info(): Package require 'libiconv' not used in components requires. Some expectations in package_info() are wrong, as far as I can say now. But where exactly?

Running with disabled log and locale it works (still with C++11 missing feature messages):

conan create . boost/1.75.0@ -pr ../../../tmp/ios_profile -o boost:without_log=True -o boost:without_locale=True

andioz · 2020-12-27T09:54:19Z

This behaviour puzzles me too. I take it as a hint to a similar problem in package_info(): after running a successful build, re-run with keeping everything:

conan create . boost/1.75.0@ -pr ../../../tmp/ios_profile -o boost:without_log=True -o boost:without_locale=True --keep-source --keep-build

I get a similar error but for zlib:

ConanException: boost/1.75.0 package_info(): Package require 'zlib' not used in components requires

How come? I don't understand, should be the same as before but just skipping compilation?

SSE4 · 2020-12-27T09:55:35Z

by default, apple-clang works in C++03 mode:

clang++ -dM -E -x c++ /dev/null | grep __cplusplus
#define __cplusplus 199711L

this can be changed by passing -std:

clang++ -dM -E -x c++ -std=c++17 /dev/null | grep __cplusplus
#define __cplusplus 201703L

this I guess can be achieved by b2 cxxstd flag, which recipe will activate automatically if you specify -s compiler.cppstd=20 for example

SSE4 · 2020-12-27T09:57:36Z

@madebr btw, I don't understand the relation between C++ standard and libiconv/zlib targets, could you clarify that?

andioz · 2020-12-27T10:00:53Z

this I guess can be achieved by b2 cxxstd flag, which recipe will activate automatically if you specify -s compiler.cppstd=20 for example

Ah ok, then I would say setting the proper options for b2 should be part of the recipe, right?

SSE4 · 2020-12-27T10:02:27Z

Ah ok, then I would say setting the proper options for b2 should be part of the recipe, right?

they are already:

conan-center-index/recipes/boost/all/conanfile.py

Line 798 in 15d6552

if self.settings.get_safe("compiler.cppstd"):

andioz · 2020-12-27T10:11:52Z

I see. But this means, this setting has to come either from command line options or the used profile? In the generated default profile for MacOS (and I guess Linux too) this value doesn't exist? Do you suggest to set it manually for every platform? I'm not sure about side effects for other packages used in a big project... But to be honest, I think I know not enough right now about that.

SSE4 · 2020-12-27T10:17:19Z

the cppstd option should be set within the conan profile, or via command line.
still, I don't think it has anything to do with the error generated. the exception goes from the conan itself:
https://github.com/conan-io/conan/blob/808b4635f0915e93a6d5c2794c1c73ca9b606bd1/conans/model/build_info.py#L282
that's hard to diagnose, I gonna try to reproduce it locally.
from that I understand, some conan component referenced requirement which wasn't required by the conanfile itself. this indicated error in the recipe logic.
IMO it shouldn't happen regardless of cppstd value.

andioz · 2020-12-27T10:19:37Z

I can confirm, after resetting the guesses to 12 (13 produces a different error), that running

conan create . boost/1.75.0@ -pr ../../../tmp/ios_profile -s compiler.cppstd=11

generates no more messages about missing c++11 features, and the config checks looks better now.

Agree

SSE4 · 2020-12-27T11:28:40Z

seems like the real problem is that boost_locale was never built, despite it was required and reported:

- locale                   : building

the actual error seems to be (config.log):

SSE4 · 2020-12-27T11:38:19Z

seems to be the same issue as:
boostorg/build#678
boostorg/build#438
the only workaround I see for now is to add -o boost:without_locale=True (probably -o boost:without_iostreams=True as well)

SSE4 · 2020-12-27T11:40:42Z

for @madebr
that's the condition in recipe that skips adding iconv if locale was never built:

conan-center-index/recipes/boost/all/conanfile.py

Line 1259 in c68b60a

if all(l in detected_libraries for l in module_libraries):

may you change it to print something more human-readable warning, e.g.:

requested to build "boost_locale", but it wasn't actually built, try adding the option `-o boost:without_locale`

madebr · 2020-12-27T14:42:14Z

I've created #3999 to have better error reporting.
It does not have @SSE4's suggestion (yet).

@andioz
Can you try building boost (without any compiler.cppstd in your profile) with #3999?

conan create recipes/boost/all boost/1.75.0@ -s compiler.cppstd=11

The pr does not change anything for apple-clang,
so my earlier remarks about the default c++ standard of apple-clang are still valid.

andioz · 2020-12-27T15:08:04Z

OK, the build passed. I cleared the cache before building, and this build is on MacOS for MacOS (no extra profile used), I used exactly the command line from above.

boost_strict_macos.log

Any other configuration to check?

madebr · 2020-12-27T15:11:39Z

Good to know that cppstd=11 works on Macos.

I suppose

conan create recipes/boost/all boost/1.75.0@

will fail with missing boost_locale, boost_nowide, boost_json, ... instead of an error about a non-used conan dependency?

andioz · 2020-12-27T15:19:37Z

Here I get again the boost warnings about missing C++11 features, and it ends with errors about missing c++11 features? noexeceptfor example.

boost_strict_macos_without_cppstd.log

andioz · 2020-12-27T15:28:13Z

Building for iOS with cppstd=11 seems to work for the library, but the test_package fails.

boost_strict_ios.log

Undefined symbols, looks something is missing here

andioz · 2020-12-27T15:41:58Z

Android build on MacOS passes.

andioz · 2021-01-25T17:47:04Z

@madebr
I tried the newest package(s) on Mac for iOS, but still get errors. I add the output of the second run, it's shorter. I want to build boost with default settings, I think it should work.

Extra note: for Android, I get a similar error but only for boost_stacktrace_addr2line (on Linux, not tested yet on MacOS, but will try - yupp same on MacOS for Android).

kaptenhonek · 2021-04-06T12:37:50Z

Have you found any workarounds for android? I get the same error about boost_stacktrace_addr2line

madebr · 2021-04-06T13:16:39Z

@andioz @kaptenhonek

boost_stacktrace_addr2line is built if b2 is able to build (and run) the following source: https://github.com/boostorg/stacktrace/blob/develop/build/has_addr2line.cpp

The boost recipe currently does not have a way to override the location of the addr2line executable.
What is the name/location of it for android/ios?
Maybe the boost recipe needs a way to pass the value of BOOST_STACKTRACE_ADDR2LINE_LOCATION.

madebr · 2021-04-06T13:21:57Z

@andioz
Does the current conan recipe still fail with a missing boost_locale library?
Can you please rebuild and post the complete log?
Posting the tree layout of the libiconv package would also be useful.

andioz · 2021-04-07T06:15:54Z

I have to update my dev environment first. I got rid of boost in my project, therefore I didn’t continue on this. But I will check, give me some time and hold on...

andioz · 2021-04-07T12:59:55Z

Here we go. I have a fresh .conan directory, python venv up-to-date. I ran both my "old" single profile method and a "new" dual profile method. Same error for both variants. libiconv tree layout: I assume you mean the build directory - this one is attached here too.

ios-build-single-profile.log
ios-build-dual-profile.log
libiconv-build-tree.txt

madebr · 2021-04-07T21:17:33Z

@andioz

I meant the tree of the libiconv package folder because that one is the folder used by boost.
But your boost logs contain its content:

libiconv/1.16 package(): Packaged 1 file: iconv
libiconv/1.16 package(): Packaged 1 '.LIB' file: COPYING.LIB
libiconv/1.16 package(): Packaged 3 '.h' files: libcharset.h, localcharset.h, iconv.h
libiconv/1.16 package(): Packaged 2 '.a' files: libcharset.a, libiconv.a

The boost logs do not contain the actual boost log. Did you remove it from the logs to reduce file size?
The logs show that -sICONV_PATH=/Users/zoufala/sandbox/github/andioz/conan-center-index/tmp/.conan/data/libiconv/1.16/_/_/package/3789018b2882bf53cb9ed8e9abd38b829172fe47 is passed to b2 (=boost build tool).
But the tool says - Boost.Locale needs either iconv or ICU library to be built.

Can you try the following:
Compile this source: https://github.com/boostorg/locale/blob/develop/build/has_iconv.cpp
with the following command with the same settings as the failing boost package.

$CXX has_iconv.cpp -I/Users/zoufala/sandbox/github/andioz/conan-center-index/tmp/.conan/data/libiconv/1.16/_/_/package/3789018b2882bf53cb9ed8e9abd38b829172fe47/include -L/Users/zoufala/sandbox/github/andioz/conan-center-index/tmp/.conan/data/libiconv/1.16/_/_/package/3789018b2882bf53cb9ed8e9abd38b829172fe47/lib -liconv

You might need to tweak the used paths.
But I want to test here whether linking to only libiconv.a is sufficient.

Re the addr2line error, I'm not sure how to address it on Macos.
The b2 detection is not really configurable.

Alternatively, we can just remove it when it's present but unwanted,
and fail when it is needed, but not present.

andioz · 2021-04-08T11:53:31Z

Ah sorry, here is the package tree for completeness:

tmp/.conan/data/libiconv/1.16/_/_/package/3789018b2882bf53cb9ed8e9abd38b829172fe47/
├── bin
│   └── iconv
├── conaninfo.txt
├── conanmanifest.txt
├── include
│   ├── iconv.h
│   ├── libcharset.h
│   └── localcharset.h
├── lib
│   ├── libcharset.a
│   └── libiconv.a
└── licenses
    └── COPYING.LIB

I didn't remove anything from the logs, it should be complete. But as you mention it: I recognized a relatively long timeout (more than a minute) after the line - wave: building. Looks like the output is suppressed here.

I'm still trying to figure out the required command line arguments for the compiler to check has_iconv.cpp, need feed back from a teammate, I'm not a regular Mac user...

andioz · 2021-04-10T08:18:11Z

OK, I managed to compile, I hope it is what you want:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang \
  -x c++ -target arm64-apple-ios9.0 \
    -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS14.4.sdk \

This produces an a.out file without error or warning:

boost_stacktrace_addr2line is built if b2 is able to build (and run) the following source: https://github.com/boostorg/stacktrace/blob/develop/build/has_addr2line.cpp

The boost recipe currently does not have a way to override the location of the addr2line executable.
What is the name/location of it for android/ios?
Maybe the boost recipe needs a way to pass the value of BOOST_STACKTRACE_ADDR2LINE_LOCATION.

I'm running into a similar problem with Boost 1.69 when trying to cross-build boost for a Raspberry Pi. The cross-compilation toolchain has addr2line as /bin/arm-linux-gnueabihf-addr2line however I can't seem to find a way to get Boost to pick it up, leading to:

    - addr2line builds         : no

...

boost/1.69.0: WARN: Boost component 'stacktrace_addr2line' is missing libraries. Try building boost with '-o boost:without_stacktrace_addr2line'.
ERROR: boost/1.69.0: Error in package_info() method, line 1404
	raise ConanException("These libraries were expected to be built, but were not built: {}".format(non_built))
	ConanException: These libraries were expected to be built, but were not built: {'boost_stacktrace_addr2line'}

Interestingly, I was previously using boost-1.69.0@conan/stable (now deprecated) and this seemed to work just fine with the same toolchain (build reports - addr2line builds : yes), so I'm not sure what's different. I can't run this one any more after the bintray sunsetting.

I was able to work around it with a boost:without_stacktrace=True but that disables the entire stacktrace component which doesn't seem like an appropriate action.

I know I have an older version of Boost but the issue seems to be the same and therefore I'm very interested in parts of this discussion.

On further reflection, I'm wondering if the issue is really with detecting libbacktrace rather than addr2line which seems more like a fall-back. However I don't know enough about the Boost build system to confirm.

EDIT: I've duplicated the same issue with Boost 1.76.0.

madebr · 2021-05-03T23:53:13Z

To everybody having a problem with boost_stacktrace_addr2line in this thread,
can they please try #5420 and report their results?

It allows to override the location of the addr2line executable with the addr2line_location option.

Thanks!
