I'm trying to build a version of vim with perl support that will run

when I fire up vim and do a test perl command like ":perl 'my $i=1;'",
vim quits with this message:
Vim: Caught deadly signal SEGV
Vim: Finished.
Segmentation fault
Versions used:
- latest cygwin as of this post (setup.exe v2.686)
- vim 7.2 sources (runtime, lang, and extras), applied patches 001
through 394
- Perl 5.10.1-3 (the one that comes with cygwin)
Steps followed:
- open a cygwin terminal...
- download, unzip and patch vim sources from vim.org
- cd vim72/src
- run './configure --enable-perlinterp --prefix=/opt/vimtest' (to
avoid interfering with cygwin's pre-existing vim)
- run 'make&& make install'
- run '/opt/vimtest/bin/vim.exe'
- try a ":perl" command -> observed segfault
Is there something I've overlooked? Can someone please point me in the
right direction, either to fix or to troubleshoot?
Thanks very much,
Peter
Running configure separately is dangerous if the "requirements" of the
Makefile have been modified, because in that case "make" will rebuild
the Makefile, running configure in the process (without your handcrafted
command-line arguments).
I recommend to set configure arguments via environment variables passed
to make, seehttp://users.skynet.be/antoine.mechelynck/vim/compunix.htm
for an example.
I'm not saying that this is necessarily your problem, but it could be,
since you applied quite a number of patches and some of them modify one
or more of Makefile, auto/configure, config.mk etc.
Also, if configure has a problem, it will return a nonzero exit code,
and in that case (if configure was invoked by make) the "compile" step
will not be launched. The config log should tell you what went wrong (I
recommend logging the console messages from configure and make via tee,
but a more detailed config.log is put in the src/auto directory; I
usually don't need that much detail to know what went wrong.
To reconfigure and recompile, use either
make reconfig
(one step) or
make config
make
(two steps), in both cases after setting the proper environment variables.
Best regards,
Tony.

Thanks for your quick reply, Tony.
I've followed your instructions on the above HowTo page, but
unfortunately the segfault problem persists. As a "control"
experiment, I also tried the procedure below replacing
'CONF_OPT_PERL=--enable-perlinterp' with 'CONF_OPT_PYTHON=--enable-
pythoninterp' - the resulting vim.exe handles ":python 'foo=123'"
flawlessly. The trouble seems to be Perl-specific.
Here's a breakdown of the steps I followed (from the HowTo):
# starting with a fresh source dir described at the top of the
thread (runtime/lang/extras + patches 001-394 applied)
cd vim 72/src
export CONF_OPT_PERL=--enable-perlinterp
export CONF_OPT_FEAT=--with-features=huge
export CONF_OPT_COMPBY="[email protected]"
export CONF_OPT_MULTIBYTE=--enable-multibyte
# I left the remaining CONF_OPT env variables unset for simplicity
(no ruby, tk, etc)
make config 2>&1 | tee config.log # ran ok ($? was 0)
make 2>&1 | tee make.log # also ran ok
But running the resulting vim.exe with command ":perl 'my $foo=123;'"
still causes the same segfault, unfortunately.
Is there anything else I could try?
Best regards,
Peter
Hm... Which perl interpreter are you using? For a Vim "for Cygwin",
_both_ the Perl interpreter used to convert src/if_perl.xs to
src/auto/if_perl.c (before compiling src/auto.if_perl.c to
src/objects/if_perl.o or similar) _and_ the one used to interpret Perl
commands issued from Vim must be the same version of Perl, which in this
case must be IIUC _not_ a Perl "for Windows" but a Perl "for Cygwin" --
but I'm not sure that I did UC.
So: What is the reply to "which perl" at the Cygwin bash prompt? Does it
look like a path to a "Cygwin" program or to a "Windows" program? Are
you running Vim-for-Cygwin from Cygwin bash (recommended), from a
Windows Dos Box, from a desktop icon, or in some other way...?
Best regards,
Tony.
