加载共享库(glew)时出错

Question

我编译了GLEW库。它似乎工作得很好，下面是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/"

现在我想在一个KDevelop项目中使用它。我使用find_package创建了我的CMakeLists.txt并在那里链接库：

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)

我没有得到任何构建错误。当我尝试运行这个程序时，下面是输出：

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

任何帮助都将不胜感激。

编辑：

使用命令locate libGLEW，我会得到以下输出：

/usr/lib64/libGLEW.so  
/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可能无法工作？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中的库创建一个符号链接来使其工作。

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

现在它工作得很好。由于我不是linux方面的专家，我不知道这会不会在未来给我带来问题。

我不知道@Ihahn的答案是否会有任何问题，但是，如果某个程序找不到你的共享库，那么首先找到你的库所安装的文件夹，并且不在你的共享库文件夹中，然后运行sudo ldconfig <location_where_your_library_or_program_was_installed>。当您通过make install.Reference here.安装/构建程序时，有时会发生这种情况。
