刪除 debuild buildsystem=cmake 連結器標誌

刪除 debuild buildsystem=cmake 連結器標誌

我正在嘗試使用 cmake 和 mingw 交叉編譯器從 debian 建立 *.deb 檔案。使用 .CMake 時，CMake 的編譯器測試失敗dpkg-buildpackage。

正常建置沒問題：

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，當我使用它來構建它時，dpkg-buildpackage它無法配置：

dpkg-buildpackage -uc -us
dpkg-buildpackage: info: source package foo
dpkg-buildpackage: info: source version 1.0
dpkg-buildpackage: info: source distribution stretch

完整日誌中有趣的部分是連結期間的失敗：

/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 連結器無法辨識該-z選項。當我diffCMakeCache.txt 時，我可以看到 dpkg-buildpakcage 預設添加一些連結器標誌：

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

我怎樣才能防止dpkg-buildpackage這樣做？

僅供參考：我的debian/rules文件如下所示：

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

答案1

您需要停用relro強化配置；改變你debian/rules的

#!/usr/bin/make -f

export DEB_BUILD_MAINT_OPTIONS = hardening=-relro

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

看線上說明dpkg-buildflags頁了解詳情。

（順便說一句，如果您使用的是相容等級 10 或更高版本，則不需要，--parallel因為預設已啟用它。在許多情況下，您--buildsystem=cmake也可以刪除它，因為dh系統會自動檢測它。）
