Recompiling with ./configure --enable-graphics=cairo worked.

Maybe in a couple of years... I'm not quite up to snuff yet.

Worked!

Is it possibly causing the problems for the last few things in
dev-libs that won't compile?
How would I resolve that? As far as I can tell, I only have one
libobjc library installed, which is libobjc2 version 4.3.2

True... because it compiles now.

So is there anything I can do short of learning how to develop gnustep-db?

Actually, I'm not using any special windowing servers, just plain old
Xorg. I've got a circa 2001 Thinkpad with an integrated Savage video
card... so all that fancy stuff just doesn't work for me :(....

It certainly did.

Thanks, Fred and Tim!


Here's what compiled after a more careful reading of the make errors:

gscrypt
Installed libpam0g-dev, compiled fine. There wasn't any README or
INSTALL file to look for dependencies in, but after reading the error
messages more carefully (duh), I ran "apt-cache --names-only search
lib pam dev" which turned up the library I needed.

smbkit
Same deal as gscrypt: needed to install libsmbclient-dev. README is
empty, and INSTALL only contains the text "make install".


Here's what still won't compile in modules/dev-libs:

db
Tim said it was a 'problem'.

So did I screw up with compiling some objc stuff?


Also, is there a dependency list for everything somewhere? I've tried
looking, but I couldn't find anything, so I just blindly attempt to
compile/install things.

Thanks,
