Description of problem: I installed FC6 from CD set (checksums verified), then installed svgalib (www.svgalib.org) both versions 1.4.3 and 1.9.25. After building according to instructions (with a few changes mainly to correct new compiler issues in 1.4.3) I tried to run a demo. It fails to load libraries, complaining that it cannot restore segment protection after relocation. Same result by doing ldd -r on the libraries. The problem is resolved and the demos run after I copy the libraries to a usb thumb-drive and change the links in /usr/local/lib to point there. I was running as root and had full permissions on all directories in the path to the demo program and the libraries, and on those files. I have used svgalib on several other Linux distros, including a Fedora Core laptop installation from Emperor Linux, without running into this issue. I can't think how to determine whether this is a FC6 issue or svgalib issue. Version-Release number of selected component (if applicable): How reproducible: completely Steps to Reproduce: see above
Fixing component and reassigning.
You built svgalib incorrectly (or it has buggy Makefiles?). Shared libraries need to be built as position independent code (i.e. using -fpic or -fPIC compile time flags). In FC6 the SELinux policy by default disallows DT_TEXTREL shared libraries (on some arches like x86_64 DT_TEXTREL has never been supported at all), unless the library uses a special SELinux type (e.g. textrel_shlib_t). On the USB thumb drive guess you don't have a filesystem that supports SELinux ACLs. The best fix is just make sure the library is built with -fpic. As a fallback, if it is not (easily) possible to fix it, you can chcon -t textrel_shlib_t the shared library.
