linux - 加载共享库时出错 (glew)

Question

我编译了 GLEW 库。它似乎工作正常，这里是 make install 的输出:

install -d -m 0755 "/usr/include/GL"
install -m 0644 include/GL/wglew.h "/usr/include/GL/"
install -m 0644 include/GL/glew.h "/usr/include/GL/"
install -m 0644 include/GL/glxew.h "/usr/include/GL/"
sed \
        -e "s|@prefix@|/usr|g" \
        -e "s|@libdir@|/usr/lib64|g" \
        -e "s|@exec_prefix@|/usr/bin|g" \
        -e "s|@includedir@|/usr/include/GL|g" \
        -e "s|@version@|1.11.0|g" \
        -e "s|@cflags@||g" \
        -e "s|@libname@|GLEW|g" \
        -e "s|@requireslib@|glu|g" \
        < glew.pc.in > glew.pc
install -d -m 0755 "/usr/lib64"
install -m 0644 lib/libGLEW.so.1.11.0 "/usr/lib64/"
ln -sf libGLEW.so.1.11.0 "/usr/lib64/libGLEW.so.1.11"
ln -sf libGLEW.so.1.11.0 "/usr/lib64/libGLEW.so"
install -m 0644 lib/libGLEW.a "/usr/lib64/"
install -d -m 0755 "/usr/lib64"
install -d -m 0755 "/usr/lib64/pkgconfig"
install -m 0644 glew.pc "/usr/lib64/pkgconfig/"

现在我想在 KDevelop 项目中使用它。我创建了我的 CMakeLists.txt 并使用 find_package 将库链接到那里:

cmake_minimum_required( VERSION 2.6 )

project(openglengine)

include_directories(headers)

set(SOURCE_FILES src/main.cpp)

set(CMAKE_CXX_FLAGS "--pedantic-errors -Wall -std=gnu++11")
add_executable(openglengine ${SOURCE_FILES} ${HEADER_FILES})

find_package(PkgConfig REQUIRED)
pkg_search_module(GLFW REQUIRED glfw3)
include_directories(${GLFW_INCLUDE_DIRS})
target_link_libraries(openglengine ${GLFW_STATIC_LIBRARIES})

find_package(GLEW)
if (GLEW_FOUND)
    include_directories(${GLEW_INCLUDE_DIRS})
    target_link_libraries (openglengine ${GLEW_LIBRARIES})
endif (GLEW_FOUND)

install(TARGETS openglengine RUNTIME DESTINATION ~/projects/OpenGLEngine/bin)

我没有收到构建错误。当我尝试在这里运行程序时，输出是:

error while loading shared libraries: libGLEW.so.1.11: cannot open shared object file: No such file or directory

我们将不胜感激。

编辑:

使用命令 locate libGLEW 我得到了这个输出:

/usr/lib64/libGLEW.so.1.11
/usr/lib64/libGLEW.so.1.11.0

这表明我有图书馆。这是否意味着命令 find_package 可能不起作用？这很奇怪，因为我没有收到任何链接错误。

Answer 1

因此，我设法通过在/usr/lib/中为/usr/lib64 中的库创建符号链接(symbolic link)来使其工作。

sudo ln -s /usr/lib64/libGLEW.so.1.11 /usr/lib/libGLEW.so.1.11

现在一切正常。由于我不是 linux 方面的专家，所以我不知道这是否会在未来给我带来问题。
