The following issue has been SUBMITTED. ====================================================================== https://cmake.org/Bug/view.php?id=15795 ====================================================================== Reported By: Sam Thursfield Assigned To: ====================================================================== Project: CMake Issue ID: 15795 Category: Modules Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2015-10-16 10:41 EDT Last Modified: 2015-10-16 10:41 EDT ====================================================================== Summary: pkg_check_modules produces incorrect results depending on contents of CMakeCache.txt Description: I got bitten by a bug involving pkg_check_modules.
If I run cmake, then edit my CMakeLists.txt to change the parameters passed to pkg_check_modules, and rerun cmake, it ignores the change that I made to CMakeLists.txt. I needed to delete the CMakeCache.txt file to get the right results. This seems like a cache invalidation bug to me -- a change in the parameters passed to to pkg_check_modules() should cause the cached values to be invalidated. I've attached a small script that reproduces the issue. Steps to Reproduce: Use attached script. It uses the 'avahi' library as an example, so needs the avahi-devel or libavahi-dev package (or whatever else your distro calls it) to be installed. Any two pkg-config modules will trigger the same error. Output on my machine: Creating initial CMakeLists.txt Avahi libs should be: avahi-gobject AVAHI LIBS: avahi-gobject;avahi-common;avahi-client;avahi-glib;glib-2.0 Updating pkg_check_modules call Avahi libs should be: avahi-gobject;avahi-common;avahi-client;avahi-glib;glib-2.0 AVAHI LIBS: avahi-gobject;avahi-common;avahi-client;avahi-glib;glib-2.0 Removing cache and trying again Avahi libs should be: avahi-gobject;avahi-common;avahi-client;avahi-glib;glib-2.0 AVAHI LIBS: avahi-gobject;avahi-common;avahi-client;avahi-glib;glib-2.0 ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2015-10-16 10:41 Sam Thursfield New Issue 2015-10-16 10:41 Sam Thursfield File Added: testcase.sh ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
