无法链接OSX travis映像中的brew installde CPPFUnit 我在Github上有一个基于CGED的C++项目，它与Travis CI一起构建。.travis.yml文件在OSX上构建时具有以下特性： language: cpp jobs: include: - os: osx compiler: gcc osx_image: xcode11.2 env: - GCC_VER="9" - MATRIX_EVAL="CC=gcc-${GCC_VER} && CXX=g++-${GCC_VER}" addons: homebrew: packages: - cppunit - mruby ... (other OS) ... before_script: - eval "${MATRIX_EVAL}" script: - cmake -D ENABLE_TESTS:BOOL=TRUE . - cmake --build . -- -j2 - ctest -j2

CPPU单元由

brew

安装

cmake命令运行正常，并在

/usr/local

（即，

CPPUNIT\u INDLUE\u DIR

被正确设置为

/usr/local/include

，而

CPPUNIT\u库

被正确设置为

/usr/local/lib/libcppunit.dylib

。但是，在构建测试时，我得到与CPPUNIT相关的未定义符号的链接错误，表明它没有正确地链接到CPPUNIT。

同样的项目可以在我的MacBook上很好地构建（也安装了brew的CPPFUnit），并且可以在Linux上正确地构建gcc-9和clang，通过apt安装了CPPFUnit

我想我需要在某个地方设置

DYLD\u LIBRARY\u PATH=$DYLD\u LIBRARY\u PATH:/usr/local/lib

，但当我这样做时，会出现新的错误：

$ cmake -D ENABLE_TESTS:BOOL=TRUE .

dyld: Symbol not found: __cg_jpeg_resync_to_restart

  Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO

  Expected in: /usr/local/lib/libJPEG.dylib

 in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO

/Users/travis/.travis/functions: line 109:  3565 Abort trap: 6           cmake -D ENABLE_TESTS:BOOL=TRUE .

The command "cmake -D ENABLE_TESTS:BOOL=TRUE ." exited with 134.

以下是源文件根目录下的CMakeLists.txt文件：

cmake_minimum_required (VERSION 3.1)
project (mrbind17 CXX)

set (CMAKE_CXX_STANDARD 17)

set (CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH}
     "${CMAKE_CURRENT_SOURCE_DIR}/cmake")


add_definitions(-g)
option(ENABLE_TESTS "Build tests. May require CppUnit_ROOT" OFF)

include_directories (${CMAKE_CURRENT_SOURCE_DIR}/include)

find_package (Mruby REQUIRED)
include_directories (${Mruby_INCLUDE_DIR})

find_package (CppUnit)
if (CPPUNIT_FOUND)
    message(STATUS "CppUnit found, unit tests will be compiled")
    message(STATUS "CPPUNIT_INCLUDE_DIR : ${CPPUNIT_INCLUDE_DIR}")
    message(STATUS "CPPUNIT_LIBRARIES : ${CPPUNIT_LIBRARIES}")
    include_directories(${CPPUNIT_INCLUDE_DIR})
    enable_testing()
    if(${ENABLE_TESTS})
        add_subdirectory (test)
    endif(${ENABLE_TESTS})
else (CPPUNIT_FOUND)
    message(STATUS "CppUnit not found, unit tests will not be compiled")
endif (CPPUNIT_FOUND)

以及测试目录中的CMakeLists.txt：

add_executable(interpreter_test main.cpp interpreter_test.cpp)
target_link_libraries(interpreter_test ${Mruby_LIBRARIES} ${CPPUNIT_LIBRARIES})
add_test(NAME interpreter_test COMMAND ./interpreter_test interpreter_test.xml)

add_executable(function_test main.cpp function_test.cpp)
target_link_libraries(function_test ${Mruby_LIBRARIES} ${CPPUNIT_LIBRARIES})
add_test(NAME function_test COMMAND ./function_test function_test.xml)

add_executable(module_test main.cpp module_test.cpp)
target_link_libraries(module_test ${Mruby_LIBRARIES} ${CPPUNIT_LIBRARIES})
add_test(NAME module_test COMMAND ./module_test module_test.xml)

如何使cmake链接正确地与CPPFUnit相对应？

请在问题帖子中显示cmake代码，而不是描述您的cmake文件？当然，我添加了它。您可以在问题帖子中显示cmake代码，而不是描述您的cmake文件吗？当然，我添加了它。
