删除 debuild buildsystem=cmake 链接器标志

删除 debuild buildsystem=cmake 链接器标志

我正在尝试使用 cmake 和 mingw 交叉编译器从 debian 创建 *.deb 文件。使用 .CMake 时，CMake 的编译器测试失败dpkg-buildpackage。

正常构建没问题：

mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr 
         -DCMAKE_VERBOSE_MAKEFILE=ON 
         -DCMAKE_BUILD_TYPE=None 
         -DCMAKE_INSTALL_SYSCONFDIR=/etc 
         -DCMAKE_INSTALL_LOCALSTATEDIR=/var

但是，当我使用它构建它时，dpkg-buildpackage它无法配置：

dpkg-buildpackage -uc -us

完整日志中有趣的部分是链接期间的失败：

/etc/alternatives/i686-w64-mingw32-gcc  -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2   -Wl,-z,relro  -Wl,--whole-archive CMakeFiles/cmTC_fc912.dir/objects.a -Wl,--no-whole-archive  -o cmTC_fc912.exe -Wl,--out-implib,libcmTC_fc912.dll.a -Wl,--major-image-version,0,--minor-image-version,0 @CMakeFiles/cmTC_fc912.dir/linklibs.rsp
/usr/bin/i686-w64-mingw32-ld: unrecognized option '-z'

mingw 链接器无法识别该-z选项。当我diffCMakeCache.txt 时，我可以看到 dpkg-buildpakcage 默认添加一些链接器标志：

< CMAKE_EXE_LINKER_FLAGS:STRING=-Wl,-z,relro
---
> CMAKE_EXE_LINKER_FLAGS:STRING=

我怎样才能防止dpkg-buildpackage这样做？

仅供参考：我的debian/rules文件如下所示：

#!/usr/bin/make -f
%:
    dh $@ --buildsystem=cmake --parallel

答案1

您需要禁用relro强化配置；改变你debian/rules的

#!/usr/bin/make -f

export DEB_BUILD_MAINT_OPTIONS = hardening=-relro

%:
        dh $@ --buildsystem=cmake --parallel

看联机dpkg-buildflags帮助页了解详情。

（顺便说一句，如果您使用的是兼容级别 10 或更高版本，则不需要，--parallel因为默认情况下已启用它。在许多情况下，您--buildsystem=cmake也可以删除它，因为dh系统会自动检测它。）
