Bug 31877

Summary:	Perl's Config.pm is broken with respect to system includes.

Description Vadim Belman 2001-11-09 16:10:00 UTC

	The following line in Perl's Config.pm breaks compilation of
multiple p5-ports and independent Perl modules:

optimize='-nostdinc -O -pipe   -DAPPLLIB_EXP="/usr/libdata/perl/BSDPAN"   -I/usr/obj/usr/src/i386/usr/include '

	Due to presence of -nostdinc any build of Perl XS fails if /usr/obj
directory has been removed prior to compilation as compiler will look for
includes in /usr/obj/usr/src/i386/usr/include instead of presumed
/usr/include.

Fix: 

Immidiate workaround would be either removal of -nostdinc or
changing the include path with proper one. I.e. one of the following will
do:

optimize='-O -pipe   -DAPPLLIB_EXP="/usr/libdata/perl/BSDPAN"   -I/usr/obj/usr/src/i386/usr/include '
optimize='-nostdinc -O -pipe   -DAPPLLIB_EXP="/usr/libdata/perl/BSDPAN"   -I/usr/include '

	No fix for buildworld is known: Perl building is a mess, Anton must
know better.
How-To-Repeat: 
	Build and install world in order to get Perl updated and BSDPAN
installed.

	# cd /usr/obj && rm -rf *
	cd /usr/ports/security/p5-Digest-MD5
	make

	And make fails.

The problem was introduced in rev. 1.27 of 
gnu/usr.bin/perl/Makefile.inc.  It is not feasible to back it out at 
this point, since rev. 1.27 fixed another problem with Perl build. 

Unfortunately, the proper fix is rather non-trivial.  As a workaround I 
suggest you to put CFLAGS=-O -pipe (or whatever other value you usually 
use) into /etc/make.conf.  This will fix the problem, but this will mean 
that buildworld will not be done *really* properly - at this point 
setting CFLAGS in /etc/make.conf leads to -nostdinc being dropped in 
places where it is supposed to be.  This will not bite a typical 
buildworld user. 

We discussed the problem with Ruslan, and he decided to try to come up 
with the proper fix in the future.

Ruslan's going to take care of this.

The offending change to gnu/usr.bin/perlMakefile.inc was backed out.
