Error Loading Shared Library (glew)

I compiled the library GLEW. It seemed to work fine, here is the output of make install:

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/"

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/"

Now I wanted to use it on a KDevelop project. I created my CMakeLists.txt and linked the library there using find_package:

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)

I get no build errors. When I try to run the program here is the output:

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

Any help will be appreciated.

EDIT:

Using the command locate libGLEW I get this output:

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

Which show that I have the library. Does that mean that the command find_package may be not working? Which is strange because I get no link errors.

Solution

  • So, I managed to make it work by creating a symbolic link in /usr/lib/ for the library that was in /usr/lib64. 

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

    Now it works fine. Since I am no expert on linux I don't know if that will bring me problems in the future.
