Re: Make problem Mac OS X

[Roger Mc Murtrie]

Hi Greg,
I've been using locate, find and grep to find missing bits and pieces.
Also the search function of Mac Finder windows (which doesn't seem to  
search all files)
On my machine
locate libltdl
produces
.
.
.
/usr/lib/libltdl.3.1.4.dylib
/usr/lib/libltdl.3.dylib
/usr/lib/libltdl.a
/usr/lib/libltdl.dylib
/usr/lib/libltdl.la

Perhaps for Debian you have to install it yourself. I think the   
libguile-ltdl is a separate thing.
Of course, to use libltdl.a you have to inclide -ltdl in your gcc link  
commands, usually by setting the environment variable before running  
configure:
LDFLAGS=-ltdl
export LDFLAGS
(Although for one package that I build, setting environment variables  
suggested by configure -help results in empty Makefiles!)
Googling libltdl leads to www.gnu.org/software/libtool. Looks like  
libltdl comes with GNU Libtool which I seem to remember having to  
install at some stage

I don't recall getting the  "you may need to run ldconfig". message,  
but I think I've had it from other installs in the past.
I never have found out how to use it. I think it comes from the loader  
and is really a message, perhaps, to gcc rather than humans.

I'm not much more than a "novice" myself, just stumble along with lots  
of trial and error.
Nowadays, package installation seems to involve one battle after  
another!

Good luck
Roger
