[bug] meson.configure() passed in the windows style path, which was escaped by libvips

[vcup]

Environment details

• Operating System+version: Windows 11 Pro 22H2
• Compiler+version: Msys2 Mingw64 gcc 12.2.0
• Conan version: 2.0.6
• Python version: 3.9.13

Steps to reproduce

1. here is profile with naming mingw

[settings]
os=Windows
arch=x86_64
compiler=gcc
compiler.version=10.2
compiler.libcxx=libstdc++11
build_type=Release

[buildenv]
CC=C:/msys64/mingw64/bin/gcc.exe
CXX=C:/msys64/mingw64/bin/g++.exe

2. using conanfile.py

from conan import ConanFile
from conan.tools.cmake import CMakeToolchain, CMakeDeps


class Demo(ConanFile):
    name = "Demo"
    version = "0.0.0"
    settings = "os", "compiler", "build_type", "arch"
    requires = "libvips/8.14.2"

    def generate(self):
        toolchain = CMakeToolchain(self)
        toolchain.generator = "Ninja"
        toolchain.generate()

        deps = CMakeDeps(self)
        deps.generate()

3. executing command

conan install . --output-folder build --build missing -s build_type=Debug --settings:build build_type=Debug --profile mingw --profile:build mingw

ERROR: libvips/8.14.2: Error in build() method, line 286
        meson.build()
        ConanException: Error 1 while executing

[vcup]

I have thoroughly debugged the process where this error occurs. The issue arises from the libvips macro VIPS_PREFIX which accepts the value of the meson command-line option -Dprefix. On Windows, the path separator \ ends up breaking the source code after it goes through the preprocessor.

conan/conan/tools/meson/meson.py

Line 50 in ae001d3

cmd += ' -Dprefix="{}"'.format(self._conanfile.package_folder)

The solution is to either directly replace \ with the Unix-like /, or two \\. In conan, this requires dealing with the ConanFile.package_folder field. In the meson.build file, it involves replacing the section where the macro is added.

cmd += ' -Dprefix="{}"'.format(self._conanfile.package_folder.replace('\\', '/'))

or in the meson.build

change to

cfg_var.set_quoted('VIPS_PREFIX', prefix_dir.replace('\\', '/'))

Should I report this issue to the libvips repository? or would it be more effective to handle this upstream in conan to solve more potential problems?

[franramirez688]

Hi @vcup - Thanks for reporting the issue!

I want to be sure if it's either a Conan or a recipe issue. Let's check the most simple case:

• Create an empty folder with a simple "Hello World" library: conan new meson_lib -d name=myhello -d version=0.1
• Copy your profile and, perhaps, add the path to the folder containing some DLLs? I'm not sure because I'm not using Windows at this moment:

[settings]
os=Windows
arch=x86_64
compiler=gcc
compiler.version=10.2
compiler.libcxx=libstdc++11
build_type=Release

[buildenv]
PATH+=(path)C:/msys64/mingw64/bin
CC=C:/msys64/mingw64/bin/gcc.exe
CXX=C:/msys64/mingw64/bin/g++.exe

[runenv]
PATH+=(path)C:/msys64/mingw64/bin

• Finally, run the example: conan create . -pr mingw -pr:b mingw

Is it happening that problem again?

[vcup]

Hello, @franramirez688 - Thanks for your response.
I have tried the method you suggested, and of course, a new recipe won't present this issue. I am quite certain that the problem is caused by the meson.build of libvips, as explained in my previous comment #14213 (comment)

Therefore, if I add similar content that causes the issue to a new recipe, the problem will be reproduced.

meson.build

project('myhello ', 'c')
executable('myhello', 'src/main.c', install: true)

prefix_dir = get_option('prefix')

cfg_var = configuration_data()
cfg_var.set_quoted('MYHELLO_PREFIX', prefix_dir)

config_file = configure_file(
    configuration: cfg_var,
    output: 'config.h'
)

main.c

#include <config.h>

int main(void) {
    return 0;
}

char *issue_func() {
    return (MYHELLO_PREFIX);
}

Here is the log
