包含Irrlicht静态库时C ++编译错误 [英] C++ compile error when includeing Irrlicht static lib

问题描述

在尝试将Irrlicht静态库包含到我的cmake项目中时，U出现编译错误

U have a compile error when trying to include the Irrlicht static libraries into my cmake project

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

make[1]: ***    [src/CMakeFiles/survival.dir/all] Error 2
make: *** [all] Error 2
max@max-MS-7369:~/Desktop/survival/build$

这就是我尝试包含lib的方法:

And this is how I try to include the lib:

# find dependencies for irrlicht
FIND_PACKAGE(ZLIB)
FIND_PACKAGE(X11)
FIND_PACKAGE(OpenGL)
# includes
set( survival_CUSTOM_INCLUDES
    ${ZLIB_INCLUDE_DIR}
    ${X11_INCLUDE_DIR}
    ${OPENGL_INCLUDE_DIR}
    ${survival_SOURCE_DIR}/irrlicht/include
    )
# libraries
set( survival_CUSTOM_LIBRARIES
    ${ZLIB_LIBRARIES}
    ${X11_LIBRARIES}
    ${OPENGL_LIBRARIES}
    ${survival_SOURCE_DIR}/irrlicht/lib/Linux/libIrrlicht.a
    )

即使我已经包含X11库，我也不知道为什么它说找不到XConvertSelection.

I don't get why it says it cant find XConvertSelection even though I have included the X11 lib.

推荐答案

我添加了这2个库来对其进行修复

i added those 2 libs to fix it

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

它们不包含在FIND_PACKAGE()提供的库中

they werent included by the libs given from FIND_PACKAGE()
