Compiler Backends (Programming Perl)Copyright ©
If the binary code for your platform is not available, you need a C compiler to compile the source code manually. Compiling the source code offers more flexibility in terms of choice of features that you require in your installation.Here is a quick overview of installing Perl on various ...
compiler, the stable branch is called 'release', the newest perl releases usually don't work immediately. I typically need 6 months to catch up for perl5. With cperl B-C is included in CORE, so this is supported to work there. Known issues: Seehttps://github.com/rurban/perl-compiler...
use feature qw(say); use strict; use warnings; use Config; { my $compiler_name = 'x86_64-conda_cos6-linux-gnu-gcc'; my $cc = $Config{cc}; my ($old_prefix) = $cc =~ m{^(.*?)/bin/$compiler_name}; die "Unexpected: Could not find old sysroot prefix." if !defined $old_...

3,注定是要失败的,因为该模块是xs模块。需要配置一个C/C++ compiler(C/c++编译器环境)。 提示:It looks like you don't have a C compiler on your PATH, so you will not be able to compile C or XS extension modules. 4,有文章推荐用Microsoft visual c++ 2005 express edition 大小462M左右。下载...
Ifrequire()fails to load the file, either because it couldn't find the file in question or the code failed to compile, or it didn't returnTRUE, then the program woulddie().To prevent this therequire()statement can be enclosed into aneval()exception-handling block, as in this example:...
