Hi,
I tried to use +perl/dyn on Cygwin and Linux, but it seems that
Vim is statically linked to the perl library.
On Cygwin (with Perl 5.14):
$ ./configure --with-feature=huge --enable-perlinterp=dynamic
$ make
$ ./vim
/cygdrive/c/(snip)/vim/src/vim.exe: error while loading shared libraries:
cygperl5_14.dll: cannot open shared object file: No such file or directory
(if cygperl5_14.dll is not available)
On Linux (Ubuntu 12.04 with Perl 5.14):
$ ./configure --with-feature=huge --enable-perlinterp=dynamic
$ make
$ objdump -p ./vim | grep perl
NEEDED libperl.so.5.14
The cause is that the symbol PL_thr_key is linked statically.
Attached patch fixes this problem when used with Perl 5.14+.
I'm not sure about the older versions of Perl. (5.12, 5.10, ...)
Best regards,
Ken Takata
