Current debian lenny comes with glibc-2.7 and does not provide __gnu_mcount_nc which will come with 2.8 as discussed on gcc-patches here:
http://gcc.gnu.org/ml/gcc-patches/2008-10/msg00319.html But this means that all the tests from gcc testsuite using -p fail to link, eg: Executing on host: /home/guerby/build-142984/gcc/xgcc -B/home/guerby/build-142984/gcc/ /home/guerby/trunk/gcc/testsuite/gcc.dg/20021014-1.c -O2 -p -lm -o ./20021014-1.exe (timeout = 300) /tmp/cc1YND67.o: In function `foo':^M 20021014-1.c:(.text+0x4): undefined reference to `__gnu_mcount_nc'^M /tmp/cc1YND67.o: In function `main':^M 20021014-1.c:(.text+0x18): undefined reference to `__gnu_mcount_nc'^M collect2: ld returned 1 exit status^M compiler exited with status 1 output is: /tmp/cc1YND67.o: In function `foo':^M 20021014-1.c:(.text+0x4): undefined reference to `__gnu_mcount_nc'^M /tmp/cc1YND67.o: In function `main':^M 20021014-1.c:(.text+0x18): undefined reference to `__gnu_mcount_nc'^M collect2: ld returned 1 exit status^M FAIL: gcc.dg/20021014-1.c (test for excess errors) May be there's a way to tell configure and/or dejagnu about missing profiling support and be a bit more graceful than a link error? -- Summary: testsuite __gnu_mcount_nc link error when profiling on arm Product: gcc Version: 4.4.0 Status: UNCONFIRMED Keywords: link-failure Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: laurent at guerby dot net GCC build triplet: arm-linux-gnueabi GCC host triplet: arm-linux-gnueabi GCC target triplet: arm-linux-gnueabi http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38703
