关于静态编译的问题

[eko5624]

谢谢您的卓越贡献，我有个问题我想咨询下。我用gcc-mcf.lhmouse.com/mingw-w64-gcc-mcf_20220606_12.1.1_x64-ucrt_fe50eb9db7d0a4c4ba907456ca4c9b5b3403a0fb.7z您这个toolchain编译mpv。但编译生成的mpv.exe需要依赖libmcfgthread-1.dll这个动态库。有没有办法把libmcfgthread-1.dll静态编译进mpv呢。这样的话只需要一个mpv.exe单文件就可以运行了。

静态链接需要给 GCC 指定 -static 参数。

build() {
  cd $srcdir/mpv
  LDFLAGS="$LDFLAGS -lstdc++ -lssp"
  meson build --buildtype=release -Dprefix=/opt --prefer-static -Db_lto=true -Db_ndebug=true
  meson compile -C build 
}

package() {
  export PKGEXT='.pkg.tar.xz'
  mkdir -p $pkgdir/opt/bin  
  cd $srcdir/mpv/build
  mv mpv.exe $pkgdir/opt/bin

-static应该加到哪个地方呢？

[lhmouse]

通常应当是 @LDFLAGS@ 里。

[eko5624]

非常棒，按照您说的修改了一下问题解决了，太感谢了~ 改成这样：LDFLAGS="$LDFLAGS -static -lstdc++ -lssp"

[eko5624]

@lhmouse LDFLAGS="$LDFLAGS -static" doesn't work now. Any ideas?

把libgcc_s_seh-1.dll和libmcfgthread-1.dll都复制到mpv文件夹里才解决问题。怎么才能去掉对libgcc_s_seh-1.dll和libmcfgthread-1.dll的依赖呢？

搜到别人遇到的同类问题，他们加LDFLAGS="-static"就解决问题了。可是对于我们这个toolchain不管用。 https://github.com/mpv-player/mpv-build/issues/195#issuecomment-1242899286

LDFLAGS is a variable specific to GNU make. You should examine the actual command line which invokes the linker (typically g++) to ensure -static actually exists there.

I know nothing about meson. You should try making meson print the full command line, with which it invokes the linker.

问题解决了，是最新版vulkan的问题，和工具链无关。
