From 87bc7c1bde9e4994c164bb3c19fd7acf25189a7d Mon Sep 17 00:00:00 2001 From: Aaron Rossetto Date: Thu, 6 Jan 2022 13:06:23 -0600 Subject: cmake: Replace distutils.sysconfig with sysconfig This commit replaces uses of distutils.sysconfig's get_python_lib() function with sysconfig's near-equivalent get_path() function to get the directory for site-specific, platform-specific files. Unfortunately, get_path() does not have a way to easily modify or strip the prefix applied to the path like get_python_lib() does, so the code must manually modify the path to get the same effect: - First, the platlib path is retrieved from the get_path() call. - Next, the default base that is used to form the pathlib path is queried via the get_config_var('base') call. - Next, the portion of the platlib path that matches the default base is stripped, and any leading path separator remaining is stripped. This fundamentally replicates the behavior of get_python_lib() with an empty prefix (i.e., the prefix positional parameter is specified as ''). - If a different prefix is desired, then the os.path.join() function is used to combine the new prefix with the stripped pathlib path, ensuring that the platform-specific path separator is used in crafting the path. --- mpm/python/CMakeLists.txt | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'mpm/python') diff --git a/mpm/python/CMakeLists.txt b/mpm/python/CMakeLists.txt index d5106b1b3..260d3bab7 100644 --- a/mpm/python/CMakeLists.txt +++ b/mpm/python/CMakeLists.txt @@ -101,7 +101,10 @@ add_custom_command(OUTPUT ${OUTPUT} add_custom_target(usrp_mpm ALL DEPENDS ${OUTPUT} pyusrp_periphs) execute_process(COMMAND ${PYTHON_EXECUTABLE} -c - "from __future__ import print_function; from distutils import sysconfig; print(sysconfig.get_python_lib(plat_specific=True, prefix=''))" + "import sysconfig;\ + platlib = sysconfig.get_path(name='platlib');\ + base = sysconfig.get_config_var('base');\ + print(platlib.replace(base, '').lstrip('/\\\\'))" OUTPUT_VARIABLE USRP_MPM_PYTHON_DIR OUTPUT_STRIP_TRAILING_WHITESPACE ) install(DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/build/lib/usrp_mpm DESTINATION ${USRP_MPM_PYTHON_DIR}) -- cgit v1.2.3
