Hi Thomas, Thanks for the hint. I'm trying to rebuild the original SRPM without the patch for know, but I'm getting the following error. rpmbuild --rebuild /tmp/clutter-1.14.4-12.el7.src.rpm ... checking for XIAllowTouchEvents... yes checking for XIScrollClassInfo.number... yes checking for XkbQueryExtension... yes checking for GDK_PIXBUF... no configure: error: Package requirements (gdk-pixbuf-2.0) were not met: Package libpng15 was not found in the pkg-config search path. Perhaps you should add the directory containing `libpng15.pc' to the PKG_CONFIG_PATH environment variable Package 'libpng15', required by 'GdkPixbuf', not found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GDK_PIXBUF_CFLAGS and GDK_PIXBUF_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. error: Bad exit status from /var/tmp/rpm-tmp.o3QHFY (%build) ... I've checked that libpng15.pc is in /usr/lib/pkgconfig. Tried to set PKG_CONFIG_PATH to /usr/lib/pkgconfig manually, but the error is the same. Do you have any idea how to work this around?
