如何使用 DEBUG_LEAKING_SCALARS 编译 perl? [英] How to compile perl with DEBUG_LEAKING_SCALARS?
本文介绍了如何使用 DEBUG_LEAKING_SCALARS 编译 perl?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使用 -DDEBUG_LEAKING_SCALARS
perlbrew install perl-5.24.1 -DDEBUGGING -DDEBUG_LEAKING_SCALARS --as perl-debug-5.24.1
但没有成功:
$ perl -V | perl -MData::Dumper -e 'local $/; $_ = <>; $h{$1} = $2 while /(-(?:DDEBUGGING|DDEBUG_LEAKING_SCALARS))(?:=(.*?))?(?=\s|$)/g; print Dumper \%h'
$VAR1 = {
'-DDEBUGGING' => undef,
'-DDEBUG_LEAKING_SCALARS' => undef
};

如何使用 DEBUG_LEAKING_SCALARS 编译 perl?
How to compile perl with DEBUG_LEAKING_SCALARS?
推荐答案
文档有错误.要使用此选项编译 perl，您应该使用下一个命令:
The doc has error. To compile perl with this option on you should use next command:
perlbrew install perl-5.24.1 -DDEBUGGING -Accflags=-DDEBUG_LEAKING_SCALARS -j9 --as perl-debug-5.24.1
我从此提交
UPD
DOC 在提交 #b49862865 时由 David Mitchell 修复.谢谢
UPD
DOC was fixed at commit #b49862865 by David Mitchell. Thanks
这篇关于如何使用 DEBUG_LEAKING_SCALARS 编译 perl?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
