@@ -277,6 +277,30 @@ the library names. The compilation of these extra libraries and the compiler optimizations slow down the build process and need more disk space. +?? I get failures during `make check'. What shall I do? + +{AJ} The testsuite should compile and run cleanly on your system, every +failure should be looked into. Depending on the failure I wouldn't advise +installing the library at all. + +You should consider using the `glibcbug' script to report the failure, +providing as much detail as possible. If you run a test directly, please +remember to set up the environment correctly. You want to test the compiled +library - and not your installed one. The best way is to copy the exact +command line which failed and run the test from the subdirectory for this +test in the sources. + +There are some failures which are not directly related to the GNU libc: +- Some compiler produce buggy code. The current egcs snapshots are ok and + the not yet released egcs 1.1 should be ok. gcc 2.8.1 might cause some + failures, gcc 2.7.2.x is so buggy, that explicit checks have been used so + that you can't build with it. +- The kernel might have bugs. For example on Linux/Alpha 2.0.34 the + floating point handling has quite a number of bugs and therefore most of + the test cases in the math subdirectory will fail. The current Linux 2.1 + development kernels have fixes for the floating point support on Alpha. + + ? Installation and configuration issues ?? Can I replace the libc on my Linux system with GNU libc? |
