Eu estava tentando instalar o perf no slackware 13.1 Quando eu corri pela primeira vez em / usr / src / linux / tools / perf, tive alguns erros. E eu encontrei este patch link E quando eu corri fazer novamente, emitiu alguns erros diferentes como abaixo. Mas eu já instalei o pacote perl perl-5.10.1-i486-1
libperf.a(trace-event-perl.o): In function 'define_flag_value':

Por fim, resolvi esse problema apenas comente a seguinte linha no 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
Parecia que o MExtUtils :: Embed gerava o LDFLAGS errado para libperl Eu também descobri que o pacote perl do slackware apenas fornece libperl.a lib estática
