我目前正在尝试使用cmake在macOS High Sierra（10.13.4）下的项目中使用cmake与Xcode版本9.3进行链接。在我描述设置之前，我应该提一下Bonmin示例（/ PATH_TO_BONMIN / Bonmin / examples / CppExample）使用包含的make文件进行编译。后面的例子我尝试在我的环境中工作，但它不起作用。因此，我认为必须存在不兼容性。

Bonmin 1.8（https://www.coin-or.org/Tarballs/Bonmin/）是使用

在我的Mac上构建的 
../configure -C --disable-shared  F77="/usr/local/bin/gfortran" FFLAGS="-fexceptions -m64 -fbackslash" CFLAGS="-fno-common -no-cpp-precomp -fexceptions -arch x86_64 -m64" CXXFLAGS="-fno-common -no-cpp-precomp -fexceptions -arch x86_64 -m64"

我的FindBonmin.cmake使用“$ {BONMIN_LIBRARY_DIR} / pkgconfig”中的包配置文件：

find_path(BONMIN_LIBRARY_DIR
        NAMES libbonmin.a 
        HINTS ...
        HINTS /usr/local/include/coin
        HINTS ${BONMIN_ROOT_DIR}/include/coin
        HINTS ${BONMIN_ROOT_DIR}/include
)

if(IS_DIRECTORY "${BONMIN_LIBRARY_DIR}/pkgconfig")
  set(CMAKE_PREFIX_PATH "${BONMIN_LIBRARY_DIR}/pkgconfig")
  set(ENV{PKG_CONFIG_PATH} "${BONMIN_LIBRARY_DIR}/pkgconfig")
else()
  message("Directory ${BONMIN_LIBRARY_DIR}/pkgconfig does not exist!")
endif()

由此我得到以下内容：

${BONMIN_LIBRARY_DIR}/pkgconfig = 
/Users/<PATH>/Bonmin-1.8/build/lib/pkgconfig

${PKG_BONMIN_INCLUDE_DIRS} = 
/Users/<PATH>/Bonmin-1.8/build/include/coin;/Users/<PATH>/Bonmin-1.8/build/include/coin/ThirdParty;/Users/<PATH>/Bonmin-1.8/build/include/coin;/Users/<PATH>/Bonmin-1.8/build/include/coin/ThirdParty

${PKG_BONMIN_LDFLAGS} = -L/Users/<PATH>/Bonmin-1.8/build/lib;-L/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/x86_64;-L/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/../../../x86_64;-L/usr/local/lib/gcc/i686-apple-darwin8/4.2.3;-L/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/../../..;-lbonmin;-lCbcSolver;-lCbc;-lCgl;-lOsiClp;-lClpSolver;-lClp;-lcoinasl;-lm;-ldl;-lOsi;-lCoinUtils;-lbz2;-lz;-framework;Accelerate;-lm;-lipopt;-framework;Accelerate;-lm;-ldl;-lcoinmumps;-framework;Accelerate;-lgfortranbegin;-lgfortran;-lSystem

这用于示例：

include_directories(${PKG_BONMIN_INCLUDE_DIRS} )
add_executable(bonminExample runnables/bonminExample.cpp)
target_link_libraries(bonminExample ${PKG_BONMIN_LDFLAGS})

其他信息：

我在尝试链接Bonmin时收到的错误消息是：

有人知道可能存在什么问题，甚至有解决方案吗？

请注意，Bonmin示例中的make文件为我提供了以下内容：

MBP:CppExample myname$ make VERBOSE=1
clang++ -fno-common -no-cpp-precomp -fexceptions -arch x86_64 -m64   -DBONMIN_BUILD `PKG_CONFIG_PATH=/Users/<PATH>/Bonmin-1.8/build/lib64/pkgconfig:/Users/<PATH>/Bonmin-1.8/build/lib/pkgconfig:/Users/<PATH>/Bonmin-1.8/build/share/pkgconfig:/opt/X11/lib/pkgconfig pkg-config --cflags bonmin`  -c -o MyBonmin.o `test -f '../../../../Bonmin/examples/CppExample/MyBonmin.cpp' || echo '../../../../Bonmin/examples/CppExample/'`../../../../Bonmin/examples/CppExample/MyBonmin.cpp

1 个答案:

答案 0 :(得分：1)

从XXX_LDFLAGS模块获取的PkgConfig变量之前，target_link_libraries调用中使用{}修改该变量：

string(REPLACE "-framework;" "-framework " PKG_BONMIN_LDFLAGS "${PKG_BONMIN_LDFLAGS}")

（"${PKG_BONMIN_LDFLAGS}"处的引号很重要。）

之后，-framework选项将被正确处理：

target_link_libraries(... ${PKG_BONMIN_LDFLAGS})

说明

使用框架时，CMake似乎错误地与pkg-config一起使用。提取时

-framework Acceletate
从pkg-config输出

，这两个单词被解释为单独的参数。所以，当传递给target_link_libraries时：

target_link_libraries(... -framework Acceletate)

-l根据命令rules附加到第二个单词：

ld .... -framework -lAccelerate

正确的命令调用应该是

target_link_libraries(... "-framework Acceletate")

这正是上述string(REPLACE)的目的：它使用;选项替换CMake参数分隔符-framework，使用普通空格。
