Fails on travis: |
|
Yes, on Darwin I'm having an issue with the --sysroot linker option. I'll
keep pushing until I get it to work since I haven't a Mac build environment.
On Windows it works flawlessly for me.
If anbody could test on Linux and report, it would be appreciated.

It fails building for all platforms on travis, but I'm not sure why. |
|
Ah now I know why, you're forcing the build to stop unless it's the android one :) |

Now, unless STL support is enabled, RTTI is also disabled as it looks safe Godot-wide. I only have needed to make regex aware. I've setup a local Mac dev environment and there the build has been correct. Let's hope Travis thinks the same… |

There was a problem hiding this comment.
I think from a maintenance standpoint it'd be better to use is_look_behind() on all builds, taking away the #ifdef and the dynamic cast.

Pushed with preprocessor talk dropped.

I'm getting this error on Linux: |
|
Could you add |
|
|
Thanks! Hmm… I wonder why such a weird path to the assembler ("/..//bin/as"). Sorry to bother you, but could you put this at the end?: If that doesn't shed any light I will suggest you upgrading your NDK to the latest release. |
|
Here's the dump: http://hastebin.com/umufuleruq.go I'll try a newer NDK yeah. |
|
Same issue with latest NDK :/ |

I've pinpointed a mistake: passing I'm also trying to enable link-time optimization. (If I weren't able to make this work soon I'd leave it for another PR.) I've pused both changes. |
|
It seems to work much better for me :) |

We found that this flag causes this error on PR godotengine#48812 which does not add any fancy inline assembly: ``` /tmp/tile_set-ce236a.s: Assembler messages: /tmp/tile_set-ce236a.s:34676: Error: selected processor does not support `bfc x0,godotengine#32,godotengine#32' clang++: error: assembler command failed with exit code 1 (use -v to see invocation) ``` That flag is mentioned in various errors related to assembler failures on arm64v8 with Clang from the Android NDK. It was added in Godot in godotengine#6958 when migrating from GCC to Clang, and is indeed referenced in the NDK's Clang migration guide: https://android.googlesource.com/platform/ndk/+/master/docs/ClangMigration.md > Especially for ARM and ARM64, Clang is much stricter about assembler rules > than GCC/GAS. Use `-fno-integrated-as` if Clang reports errors in inline > assembly or assembly files that you don't wish to modernize. We don't get those errors nowadays so it seems the flag is no longer needed.

This is something I wanted to do for a long time.
This must be heavily tested (different combinations of target architectures and build variants, etc.).
Not possible on Windows until #6844 is solved. For testing on Windows, merge #6959 first.### WARNING: This is not ready to be tested/merged until I fix the Mac build since I will be pushing test commits until I get it to work. I'll remove this notice as soon as that's done.NDK_TARGET/NDK_TARGET_X86since only one Clang version is included, thus no choice possible. Regarding binutils and gnu-libstdc++ the NDK also includes only one version (4.9), so no choice there either.android_stl=yes.Fix cases of bad indentation.(Superseeded by the new PEP8 effort).
