Question

我是C ++和XML的新手，我正在使用cmake来编译一些GEANT4代码。在“ make”命令之后，链接CXX可执行文件似乎存在问题

我正在Mac OSX10.14.6，geant4 10.5， C / CXX编译器标识为AppleClang 10.0.1.10010046

这是链接XML部分的代码。

XMLConfiguration* Cfg = new XMLConfiguration("mammact");
Cfg->readFile("mammact.xml");

当我从main.cc，include和src中删除与代码相关的所有XML部分时，我可以运行它。但是当我包含XML部分时，会出现以下错误；

[100%] Linking CXX executable mammactcone

Undefined symbols for architecture x86_64:
"xercesc_3_2::XMLPlatformUtils::Initialize(char const*, char const*, xercesc_3_2::PanicHandler*, xercesc_3_2::MemoryManager*)", referenced from:

XMLConfiguration::XMLConfiguration(char const*) in XMLConfiguration.cc.o
.
.
.
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

由于我是编程的新手，所以我在编码时正在学习东西，因此，我恳请您提供比对编程人员更加清楚的解决方案/建议：）

这是我的CMakeLists.txt：

正确链接Xerces库后，该问题似乎已解决。

target_link_libraries(mammactcone ${Geant4_LIBRARIES} ${MPI_LIBRARIES} ${XercesC_LIBRARIES})

如何修复“对于架构x86_64clang未找到ld：符号：错误：链接器命令失败，退出代码1（使用-v查看调用）”？
