https://github.com/matplotlib/matplotlib/pull/4430 From 3761303016cab0542891374032eca87e74d585bf Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 15 May 2015 03:43:17 -0400 Subject: [PATCH 2/3] setupext: do not mess with PKG_CONFIG_PATH The current code always sets PKG_CONFIG_PATH to build paths in / which breaks cross-compiling -- things like /usr/lib are for the build system (e.g. x86) and not for the target (e.g. arm). Since we're adding paths that are already the default for pkg-config, there's no point in trying to be smart here. Just punt the code. This basically reverts commit 101beb975d3a1218350f02bf68dc2a43ac8ff148. --- setupext.py | 15 --------------- 1 file changed, 15 deletions(-) diff --git a/setupext.py b/setupext.py index 29cddf9..57d80e7 100755 --- a/setupext.py +++ b/setupext.py @@ -252,7 +252,6 @@ class PkgConfig(object): if sys.platform == 'win32': self.has_pkgconfig = False else: - self.set_pkgconfig_path() self.pkgconfig = os.environ.get('PKG_CONFIG', 'pkg-config') status, output = getstatusoutput("%s --help" % self.pkgconfig) self.has_pkgconfig = (status == 0) @@ -262,20 +261,6 @@ class PkgConfig(object): " pkg-config is not installed.\n" " matplotlib may not be able to find some of its dependencies") - def set_pkgconfig_path(self): - pkgconfig_path = sysconfig.get_config_var('LIBDIR') - if pkgconfig_path is None: - return - - pkgconfig_path = os.path.join(pkgconfig_path, 'pkgconfig') - if not os.path.isdir(pkgconfig_path): - return - - try: - os.environ['PKG_CONFIG_PATH'] += ':' + pkgconfig_path - except KeyError: - os.environ['PKG_CONFIG_PATH'] = pkgconfig_path - def setup_extension(self, ext, package, default_include_dirs=[], default_library_dirs=[], default_libraries=[], alt_exec=None): -- 2.4.0
