Starting with version 8, the preferred name for the IA Intel compiler is icc same name as on x Thus, the configure-line should look like this:. GCC v3. The workaround is to issue the following commands before running configure :. If libunwind seems to not work backtracing failing , try to compile it with -O0 , without optimizations.
There are some compiler problems depending on the version of your gcc. General building instructions apply. This port has been removed as of and is indeed no longer needed. Unless you have a very recent C library and compiler installed, it is currently expected to have the following tests fail on IA Linux:.
This does not mean that libunwind cannot be used with older compilers or C libraries, it just means that for certain corner cases, unwinding will fail.
Since they’re corner cases, it is not likely for applications to trigger them. Note: If you get lots of errors in Giatest-nat and Liatest-nat , it’s almost certainly a sign of an old assembler. The GNU assembler used to encode previous-stack-pointer-relative offsets incorrectly. This bug was fixed on Sep so any later assembler will be fine. Caveat: GCC v3. You can try to run it, but most tests will fail and some may fail to terminate.
The only test programs that are known to work at this time are:. The following six tests are consistently failing:. This distribution includes a few simple performance tests which give some idea of the basic cost of various libunwind operations. After building the library, you can run these tests with the following commands:.
