Remova os sinalizadores do vinculador de buildsystem=cmake

  • 772

Estou tentando criar um arquivo *.deb do debian usando cmake com um compilador cruzado mingw. O teste do compilador do CMake falha ao usar o dpkg-buildpackage.

Construir normalmente é bom:

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

-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features

No entanto, quando eu construo isso usando dpkg-buildpackage, ele falha ao configurar:

dpkg-buildpackage -uc -us

dpkg-buildpackage: info: source version 1.0
dpkg-buildpackage: info: source distribution stretch

  The C compiler "/etc/alternatives/i686-w64-mingw32-gcc" is not able to
  compile a simple test program.

A parte interessante do log completo é uma falha durante a vinculação:

/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'

O vinculador mingw não reconhece a -zopção. Quando eu diffo CMakeCache.txt, posso ver que dpkg-buildpakcage adiciona alguns sinalizadores de vinculador por padrão:

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

Como posso evitar dpkg-buildpackagefazer isso?

FYI: meu debian/rulesarquivo se parece com isso:

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

  1. Best Answer

    Você precisa desabilitar a relroconfiguração de proteção; mude o seu debian/rulespara

    #!/usr/bin/make -f

export DEB_BUILD_MAINT_OPTIONS = hardening=-relro

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

    Consulte a página de dpkg-buildflagsmanual para obter detalhes.

    (Como um aparte, se você estiver usando o nível de compatibilidade 10 ou superior, você não precisa --parallel, pois está ativado por padrão. Em muitos casos, você pode descartar --buildsystem=cmaketambém, pois dho detectará automaticamente.)
