| Subject: | [PATCH] build help for VMS |
After a long hiatus, I got Module::Install working on VMS again. The attached patch does the
following things.
1.) The new() method does various things with $base_path that assume it is in Unix format.
On VMS, it isn't unless we make it so, so make it so.
2.) In find_extensions, set no_chdir for File::Find because various things change the current
working directory out from underneath us.
3.) In find_extensions, when reading the contents of a package in order to correct the case of
the package name, split on lines instead of characters because not many package names are
only one character long.
4.) In Module::Install::Can::can_cc(), just use ExtUtils::CBuilder on VMS to determine whether
we have a C compiler instead of the existing, hopelessly non-portable method. It seems like
this should be done on all platforms, but perhaps there is a version dependency.
