>Description:
1. editors/emacs20 tries to link against libXaw.so (-lXaw). This library is called in pkgsrc libXaw6.so a/o libXaw7.so.

Options:

        emacs-pop inet6 x11 xaw


        * XAW_TYPE = standard


2. On linux, emacs20 does not run (slackware 13 - gcc-4.3.3, CLAGS=-O2 -march=pentium4)

# /usr/current/bin/emacs
Fatal error (11).Segmentation fault


Nowadays, emacs20 coredumps on a lot of machines. Time to retire this package?

 It works for me (TM):

 % ldd /usr/pkg/bin/emacs
 /usr/pkg/bin/emacs:
         -lXaw7.7 => /usr/pkg/lib/libXaw7.so.7
             :

 That's emacs20 with pkgsrc libXaw-1.0.7. However, that's not on Linux.
 Perhaps the configure script is examining your /usr/X11R6, but the
 build is using the buildlinked pkgsrc libs?

 What's it crashing on? If it's using mixed versions of X libraries (as
 point (1) suggests it may be) core dumping isn't particularly a
 surprise.

 Now, that I try to compile emacs20 again, I don't have any problems with linking libXaw, anymore.

 I used to have X stuff from my linux distribution installed, but not anymore. When I filed the bug report I *may* have had still the X stuff from my linux distribution. So, you may be right.

 It crashes on startup. I found the problem. From the Makefile:

 # This matches NetBSD <1.7 releases and 1.6A-1.6P, where ld is <2.13.2.1.
 .if (${OPSYS} == "NetBSD" && \
     (empty(OS_VERSION:M1.[0-5]*) && \
      empty(OS_VERSION:M1.6_*) && \
      empty(OS_VERSION:M1.6) && \
      empty(OS_VERSION:M1.6.[0-9]*) && \
      empty(OS_VERSION:M1.6[A-P]*))) || \
     (${OPSYS} == "DragonFly")
 # If using GNU ld 2.13.2.1 or later, avoid creating combined reloc
 # sections and .data reloc sections, both of which Emacs can't handle
 # properly.  Analyzed by Stephen Ma.
 LDFLAGS+=	-Wl,-z,nocombreloc
 .endif


 Nowadays, most Linux-distributions should have ld 2.13.2.1 or later. Suggestion:

 Replace

     (${OPSYS} == "DragonFly")

 with

     (${OPSYS} == "DragonFly") ||
     (${OPSYS} == "Linux")

 With that change, emacs20 works on linux slackware 13.0.




 I encountered one voodoo-magic problem

 When I compile editors/emacs20 with -O2 or -O1, I get

 /tmp/pkgsrc/editors/emacs20/work/emacs-20.7/lib-src/sorted-doc.c:12: error: conflicting types for 'malloc'
 /tmp/pkgsrc/editors/emacs20/work/emacs-20.7/lib-src/sorted-doc.c: In function 'fatal':


 mk.conf:
 CFLAGS+=		-O2
 CXXFLAGS+=		-O2


 (commenting out the two malloc declarations in sorted-doc.c fixes the problem).



 When I compile emacs20 with -O0, everything compiles (the error is now a warning and there is a built-in function opposed to ???).

 /tmp/pkgsrc/editors/emacs20/work/emacs-20.7/lib-src/sorted-doc.c:12: warning: conflicting types for built-in function 'malloc'

 mk.conf:
 CFLAGS+=-O0
 CXXFLAGS+=-O0



 Environment: gcc-4.3.3 on Slackware 13.0

 Log Message:
 emacs20: retire elaborate logic to match versions of NetBSD below 1.7

 older binutils worked fine without this option, and it was a performance
 hit, but it's unrealistic to see anyone using such old binutils today.

 not matching some operating systems will cause runtime crashes.

 forgotten to apply patch in PR pkg/43091: emacs20 doesn't work
 (..on linux, which doesn't match the elaborate logic)

 bump PKGREVISION as it is only apparent at runtime.
