What does
which xsubpp
give on your system ?

Mac OS X 10.9 has this:
/usr/bin/xsubpp

(And I have perl from /usr/bin/perl):
which perl
/usr/bin/perl

Does it help to adjust your $PATH to use perl from /usr/bin ?

Hi,

Unfortunately Perl failed when building 3.15.1 on OS X Yosemite, with PERL 5.16.3 installed by MacPorts,

$ which perl
/opt/local/bin/perl
$ $ perl -V:bin
bin='/opt/local/bin';

The xsubpp program should be /opt/local/bin/xsubpp.
$ ls -l /opt/local/bin/xsubpp*
lrwxr-xr-x  1 root  admin    11 Oct 18 22:41 /opt/local/bin/xsubpp -> xsubpp-5.16
-rwxr-xr-x  1 root  admin  4576 Oct 18 22:40 /opt/local/bin/xsubpp-5.16

This creates the following warning,
=========
$ perl -CSD /usr/bin/xsubpp -typemap /opt/local/lib/perl5/5.16.3/ExtUtils/typemap ../Cap5.xs > Cap5.c_new && mv Cap5.c_new Cap5.c
perl version 5.16.3 can't run /usr/bin/xsubpp.  Try the alternative(s):

/usr/bin/xsubpp5.16 (uses perl 5.16)
/usr/bin/xsubpp5.18 (uses perl 5.18)

Run "man perl" for more information about multiple version support in
Mac OS X.
=========

Maybe one should not hardcode perl’s binary path, but derive it from perl config:

   PERLBIN = $(shell $(PERL) ../perlConfig.pl bin)

   XSUBPP = $(firstword $(wildcard $(PERLBIN)/xsubpp $(EXTUTILS)/xsubpp))

This fixes my problem.

Best

Thanks guys. I committed Michael's version and added a patch to the
3.14.12 Known Problems page.

In RHEL 6 /usr/share/perl5/Extutils/xsubpp exists as a soft-link to
/usr/bin/xsubpp, while earlier Perl versions have it only in Perl's
ExtUtils directory.

A more (OS) portable way to accomplish this

XSUBPP = $(firstword $(wildcard /usr/bin/xsubpp $(EXTUTILS)/xsubpp))

Hi,

I tried to compile EPICS under "Scientific Linux release 7.0 (Nitrogen)"

It failed, because xsubpp is no longer here:
/usr/share/perl5/Extutils/xsubpp
but found here:
/usr/bin/xsubpp

Thanks to Götz, who helped me debugging the error and finding a fix.

For now I added a shell script to see where xsubpp is.
The following applies to base-3.15.1-rc1 (but the problem is in older
bases as well)

Does this sound reasonable, or are there better ways ?
