| Subject: | 3.05 breaks XS modules on Cygwin/perl-5.10 |
Cross posted from https://rt.cpan.org/Public/Bug/Display.html?id=71897.
XS modules fail to compile on Cygwin with error (sample):
~~~~~~
lib/Archive/Extract/Libarchive.c:207:1: error: external linkage required
for symbol ‘XS_Archive__Extract__Libarchive__extract’ because of
‘dllexport’ attribute
lib/Archive/Extract/Libarchive.c:208:1: error: external linkage required
for symbol ‘XS_Archive__Extract__Libarchive__extract’ because of
‘dllexport’ attribute
~~~~~~
See attached file for more info on environment and build log.
Using 3.04 works fine.
Thanks,
-Mithun
