dyld 没有加载 Ogre 库

Question

I am trying to setup an environment to develop an Ogre3D application. I have manually compiled Ogre into folder /opt/Ogre3D/ogre-1.11.5/build and created a CMake project in CLion with this content:

cmake_minimum_required(VERSION 3.13)
project(sample)

set(CMAKE_CXX_STANDARD 14)
set(OGRE_DIR /opt/Ogre3D/ogre-1.11.5/build/sdk/cmake)

# specify which version and components you need
find_package(OGRE 1.11 REQUIRED COMPONENTS Bites RTShaderSystem)

# copy resource.cfg next to our binaries where OGRE looks for it
file(COPY ${OGRE_CONFIG_DIR}/resources.cfg DESTINATION ${CMAKE_BINARY_DIR})

add_executable(sample main.cpp)
target_link_libraries(sample ${OGRE_LIBRARIES})

when I try to run it, compilation is OK but then it can't execute it:

/Users/diego/CLionProjects/ogre/sample/cmake-build-debug/sample
dyld: Library not loaded: @executable_path/../Frameworks/OgreBites.framework/Versions/1.11.5/OgreBites
  Referenced from: /Users/diego/CLionProjects/ogre/sample/cmake-build-debug/sample
  Reason: image not found

Process finished with exit code 6

I have looked at otool -l /opt/Ogre3D/ogre-1.11.5/build/lib/macosx/OgreBites.framework/Versions/1.11.5/OgreBites and there is a command LC_ID_DYLIB with the name @executable_path/../Frameworks/OgreBites.framework/Versions/1.11.5/OgreBites , which matches the path given in the runtime error. However I don't know which step to take now as I have few experience with native library resolution on macOS.

Update:

Executing the command install_name_tool makes the linker find the library, but then it fails with the next one. I suppose/hope there is an option in CMake to pass it to the compiler so the binary files created during Ogre's compilation do not use the @execute_path directive?

Answer 1

I'm faced with the same problem, when using clion to build ogre in macos.

I found the symbolic links were invalid in the directory cmake-build-debug/bin/SampleBrowser.app/Contents/Frameworks .

I guess these symbolic links should point to these frameworks int the cmake-build-debug/lib/macosx. So I modified the file where executed ln to create these symbolic links.

In the file Samples/Browser/CMakeLists.txt, change

set(OGRE_OSX_BUILD_CONFIGURATION "${CMAKE_OSX_SYSROOT}/$(CONFIGURATION)")

into

set(OGRE_OSX_BUILD_CONFIGURATION "macosx")

And clean and rebuild, then the problem will disappear.
