Shared Objects¶

macOS¶

Apple has several ways of locating shared libraries:

@executable_path : relative to the main executable @loader_path : relative to the referring binary @rpath : relative to any of a list of paths. @rpath is the most recent addition, introduced in OS X 10.5.

If for instance you want to have your executable in Contents/MacOS and libraries in Contents/Libraries you could do the following:

install_name_tool -id @rpath/Libraries/lib_this.dylib builddir/lib_this.dylib and in the top-level executable set rpath with:

install_name_tool -add_rpath @loader_path/.. myexecutable and:

install_name_tool -change builddir/lib_this.dylib @rpath/Libraries/lib_this.dylib myexecutable Note: that the first path after -change must match exactly what is currently in the binary.

If you get lost otool -l -v myexecutable will tell you what load commands exactly are currently in the executable.

See man dyld and man install_name_tool for more information.

Linux¶

Windows¶

Anaconda¶

Windows .dlls should be located in %PYTHON_DIR%\Library\bin macOS .dlybs shouuld be located in $PYTHON_DIR/lib Linux .so should be located in $PYTHON_DIR/lib

Python¶

Windows .so should be located in %PYTHON_DIR%\DLLs macOS .so should be located in %PYTHON_DIR%/lib/python3.6/lib-dynload linux .so should be located in %PYTHON_DIR%/lib/python3.6/lib-dynload
