415: Abiword fixed

Thanks for the feedback on 415. Abiword crashes when an attempt is made to print. Running abiword from a terminal shows that a symbol is missing from libgnomecups. The following reads like one of those who-done-it TV shows...

Right, well I had upgraded libgnomecups. That's the problem we run into when just some libraries are upgraded. The original Puppy 400 was compiled in T2. Since then we have been upgrading a bit at a time.

But not to worry, this is fixable. I am taking the opportunity to upgrade the 'wv' package. This provides MS Word import/export capability so is important. Puppy 412 has wv 1.2.4 and the latest is 1.2.5.

wv 1.2.5
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=i486-pc-linux-gnu

abiword 2.6.3
The other dependencies are already present, so no problem, however there is a bit of a trick required when configuring abiword. If you run the 'configure' script, the internal 'goffice' gets chosen, but that is wasteful as 41x already has goffice 0.6.3 package installed. This is what you have to do:

Edit 'configure', change "libgoffice-0.4" to "libgoffice-0.4":

GOFFICE_VERSION_REQUIRED='0.4.0'
goffice_modules="libgoffice-0.6 >= $GOFFICE_VERSION_REQUIRED"

# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-printing --enable-threads --disable-gucharmap --disable-scripting --without-ImageMagick

Configured to build on a Unix/Linux platform.
Configured with printing capabilities.
Configured with XFT support.

Ah, but still had the crashing bug. Ttuuxxx reported that CUPS had to be recompiled, so I will do that too:

cups 1.1.23
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --disable-dbus --enable-openssl --disable-pam --with-logdir=/var/cups/log

...oh dear, won't compile, a missing symbol in libpng.

Yes, back when all of this was done in T2, November 2007, I patched libpng. The patched package is currently installed, it has been in 4.x all along, so I don't know what is wrong here. The patch was required because cups 1.1.23 needs a symbol (png_read_destroy) in libcups that is no longer exported. The patch fixed that. I do have that patched source, so might as well compile that:

libpng 1.2.22-patched1
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=i486-pc-linux-gnu

Yep, cups now compiles ok. Now for the moment of truth, selecting "File->Print preview..." in abiword... oh dear, still crashes:

abiword: symbol lookup error: /usr/lib/libgnomecups-1.0.so.1: undefined symbol: ippNewRequest

Okay, a quick little test. I had upgraded libgnomecups prior to releasing 415. The version in pup 412 is 0.2.2 and I had upgraded to 0.2.3. Substituting the original library file from pup 412... yes, abiword print-preview works!

So all the rigmarole above probably wasn't necessary. Yeah, but what is wrong with the libgnomecups that I compiled before? Trying again:

libgnomecups 0.2.3
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=i486-pc-linux-gnu

...nup, abiword crashes. Now trying the previous version:

libgnomecups 0.2.2
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=i486-pc-linux-gnu

ABIWORD PRINT PREVIEW NOW WORKS!!!!

The entire problem was the move from libgnomecups 0.2.2 to 0.2.3, where a symbol disappeared that abiword needs.
Alright, I'll probably put all of the above into the next pup, 416. It might look pretty tedious what I went through, and it was, but at least I have found that both the libpng and libgnomecups needed to be fixed.
