Cannot install Algorithm::AhoCorasick::XS on Windows 10, MSYS2: ‘sigjmp_buf’ does not name a type; did you mean ‘Sigjmp_buf’

问题

I am trying to install Algorithm::AhoCorasick::XS on Windows 10, MSYS2:

$ perl Makefile.PL

What can be the problem here?

回答1:

It seems like the C++ option -std=c++11 is confusing MSYS2. In Makefile.PL line #20, we have:

CCFLAGS       => '-Wall -std=c++11',

if I remove -std=c++11 and save the file and recompile, it works fine:

$ make clean
$ perl Makefile.PL
