Subject: [PATCH 24/36] perf tools: Fix up build in hardnened environments

From: Jiri Olsa <>

On Fedora systems the perl and python CFLAGS/LDFLAGS include the
hardened specs from redhat-rpm-config package. We apply them only for
perl/python objects, which makes them not compatible with the rest of
the objects and the build fails with:

  /usr/bin/ld: perf-in.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -f
  /usr/bin/ld: libperf.a(libperf-in.o): relocation R_X86_64_32S against `.text' can not be used when making a shared object; recompile w
+ith -fPIC
  /usr/bin/ld: final link failed: Nonrepresentable section on output
  collect2: error: ld returned 1 exit status
  make[2]: *** [Makefile.perf:507: perf] Error 1
  make[1]: *** [Makefile.perf:210: sub-make] Error 2
  make: *** [Makefile:69: all] Error 2

Mainly it's caused by perl/python objects being compiled with:


which prevent the final link impossible, because it will check
for 'proper' objects with following option:
