Presumably this is the desired default build behavior? Perhaps my build syntax is missing something. ![]() Grep -C1 install_name /Volumes/ramdisk/osx_ffmpeg/modules/core/cmake_install.cmakeĮXECUTE_PROCESS(COMMAND "/usr/bin/install_name_tool"īasically I'd like to configure the installed libraries with correct embedded absolute path names, so that I can link to them directly without using DYLD_LIBRARY_PATH or the like. The relative path seems to be set during installation in the generated cmake_install.cmake file via the install_name_tool command as shown here.

Otool -D /Volumes/ramdisk/osx_ffmpeg/lib/libopencv_core.2.4.3.dylib The libraries in the build location after the make command but before the "make install" are configured with the correct absolute path name corresponding to the build tree location: opt/local/lib/libopencv_core.2.4.3.dylib: First install the FFmpeg package using either Homebrew or a binary build. Otool -D /opt/local/lib/libopencv_core.2.4.3.dylib Please remember that since October 2019 it is no longer safe to use macOS. The CMAKE_INSTALL_PREFIX=/opt/local puts the libraries in the correct place after a "make install" but the embedded path names are configured with a relative path name such as "lib/libopencv " and not "/opt/local/lib/libopencv" as desired. When I compile OpenCV for Mac OSX 10.8 using XCode 4.5.2 and cmake 2.8.9 my installed libraries aren't configured with the correct corresponding installation path.Ĭmake -G "Unix Makefiles" -D CMAKE_BUILD_TYPE=RELEASE -D WITH_QT=ON -D WITH_OPENGL=ON -DCMAKE_INSTALL_PREFIX=/opt/local. ![]()
