我试图在 slackware 13.1 上安装 perf 当我第一次在 /usr/src/linux/tools/perf 运行 make 时,出现了一些错误。我找到了这个补丁 http://www.valimar.it/repo/linux/perf_fix-2.6.33.patch 当我再次运行 make 时,它发出了一些不同的错误,如下所示。但我已经安装了 perl 软件包 perl-5.10.1-i486-1

答案1
最后我通过注释掉 Makefile 中的以下行解决了这个问题
#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
看起来 MExtUtils::Embed 为 libperl 生成错误的 LDFLAGS 我还发现 slackware perl 包仅提供静态库 libperl.a
