I was trying to install perf on slackware 13.1 When I first ran make at /usr/src/linux/tools/perf I got some errors. And I found this patch http://www.valimar.it/repo/linux/perf_fix-2.6.33.patch And when I ran make again, it issued some different errors as below. But I've already installed perl package perl-5.10.1-i486-1

Finally I solved this problem by just comment out the following line in Makefile

#ifndef NO_LIBPERL
#PERL_EMBED_LDOPTS = `perl -MExtUtils::Embed -e ldopts 2>/dev/null`
#PERL_EMBED_CCOPTS = `perl -MExtUtils::Embed -e ccopts 2>/dev/null`
#endif

It looked like MExtUtils::Embed generate wrong LDFLAGS for libperl I also found that slackware perl package only provide the static lib libperl.a

  • Thanks. This allowed me to solve my isse with perf as well (though on Gentoo rather than Slackware, with kernel2.6.36-gentoo-r4)... though instead of modifying Makefile I just ran make with NO_LIBPERL=1 (though I do have libperl.so; I don't know why those errors either). – Jakub Narębski Jun 22 '11 at 18:02
