C++编译错误：包含Irrlicht静态库时的问题

Question

当尝试将Irrlicht静态库包含到我的cmake项目中时，出现编译错误。

编译错误：

max@max-MS-7369:~/Desktop/survival/build$ make Scanning dependencies of target survival [ 33%] Building CXX object src/CMakeFiles/survival.dir/technic.cpp.o [ 66%] Building CXX object src/CMakeFiles/survival.dir/render.cpp.o [100%] Building CXX object src/CMakeFiles/survival.dir/survival.cpp.o Linking CXX executable ../debug/survival /usr/bin/ld: ../../irrlicht/lib/Linux/libIrrlicht.a(CIrrDeviceLinux.o): undefined reference to symbol 'XConvertSelection' /usr/bin/ld: note: 'XConvertSelection' is defined in DSO /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libX11.so so try adding it to the linker command line /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libX11.so: could not read symbols: Invalid operation collect2: ld returned 1 exit status make[2]: *** [debug/survival] Error 1 make[1]: *** [src/CMakeFiles/survival.dir/all] Error 2 make: *** [all] Error 2 max@max-MS-7369:~/Desktop/survival/build$

这是我尝试包含库的方法：

# 查找Irrlicht的依赖项 FIND_PACKAGE(ZLIB) FIND_PACKAGE(X11) FIND_PACKAGE(OpenGL) # 包含文件 set( survival_CUSTOM_INCLUDES ${ZLIB_INCLUDE_DIR} ${X11_INCLUDE_DIR} ${OPENGL_INCLUDE_DIR} ${survival_SOURCE_DIR}/irrlicht/include ) # 库文件 set( survival_CUSTOM_LIBRARIES ${ZLIB_LIBRARIES} ${X11_LIBRARIES} ${OPENGL_LIBRARIES} ${survival_SOURCE_DIR}/irrlicht/lib/Linux/libIrrlicht.a )

我不明白为什么它说找不到'XConvertSelection'，即使我已经包含了X11库。

我添加了这两个库来修复它。

/usr/lib/x86_64-linux-gnu/libX11.so
/usr/lib/x86_64-linux-gnu/libXxf86vm.so.1

在FIND_PACKAGE（）给定的库中没有包含它们。
