On OS X, I’ve installed XForms and compiled the demos and they all work.
But trying to compile the simplest program directly, e.g.
gcc -o pshme pshme.c -lforms
fails with "ld: library not found for -lforms”
Same happens if I tell gcc where to look:
gcc -o pshme pshme.c -L/….../xforms-1.2.4/lib -lforms
ls lib/*forms*
lib/forms.c lib/forms.lo lib/forms.o lib/libforms.la lib/xforms.5 lib/xforms.man
No doubt it is something very trivial, but I’ve spent a long time trying to fix this.

Try putting in the full path name instead of a relative path name.
the library is called libforms.so and that is what the -lforms looks for.
Where is your libforms.so ?

Maybe you do not have the libforms library istalled?

Did you install it (i.e. did you run "make install")? And if you
did, did it get installed in a path the linker checks for per
default? The default for the installation is '/usr/local/lib'.
And even then you may have to make the runtime linker aware of
newly installed libraries.
I have no experience with OS X, but on Linux you need to run
'ldconfig' (as root) before it gets found after installing it
for the very first time. And the runtime linker can be made
to include '/usr/local/lib' into the default search path by
editing /etc/ld.so.conf' or, on newer systems, creating a file
with in 'etc/ld.so.conf.d'. Perhaps it's handled in a similar
way under OS X?

The finished library is in 'lib/.lib', not in the 'lib'
directory itself. So it should work with

doing some odd stuff. Digging into some old projects I see things like
this:
gcc -O3 -I/usr/local/include -I/opt/X11/include -L/usr/local/lib -l forms mycode.c
If the above does not help then you may need to dig through BSDisms like
this, good luck!

am not sure if this is still true but it was at one point.
I have some bash scripts with code like this:
P=`pwd'/lib/mylib
gcc blabla -L$P

Thank you all for your suggestions. I had already used the -I option to locate header files, and I used absolute not relative path for -L. I will try them out tomorrow, as I had minor fall off my bike on way home for lunch! (May have injured shoulder). The guide states that the Xpm library is named libforms??

Which guide states that where? If some XForms related documentation
claims that it's definitely a bug I would like to get rid off!
Hope you shoulder is ok, Jens

Was the xforms lib installed before or after the last OS upgrade?
I have been reading in some other mailing lists[2] that some features of the new System Integrity Protection [1] (AKA rootless) has been causing issues with packages that want to install links in / or /usr, also there is an issue with boost [3] that might be similar.
Food for thought? Places to ask what their related solutions were?

The forms library is in /usr/local/lib.
I had wrongly assumed that since I was installing XForms in my own directory the forms library would be there too.
The object files (*.o) but not the library (forms.a) are in xforms-1.2.4/lib/.lib.
