I am trying to compile a molecular image viewing program called Molscript. I made a few changes to the Makefile but cannot get it to finish compiling. I keep getting the following:

[localhost:/usr/local/molscript-2.1.2] root# make
cc -o molscript molscript.tab.o global.o lex.o col.o select.o state.o graphics.o segment.o coord.o xform.o postscript.o raster3d.o vrml.o regex.o clib/clib.a -lm
/usr/bin/ld: Undefined symbols:
_eps_set
_eps_set_bw

_jpgi_set

_ogl_set
_ogl_set_accum
_pngi_set
_pngi_set_compression
_sgii_set
_glutStrokeRoman
make: *** [molscript] Error 1

I know a lot of this is program specific, but what does the "Error 1" mean?

Sorry for the newbie question, but I used to use this program on our IRIX system and want to try it on my mac.

In case anyone is interested, the program is at http://www.avatar.se/molscript/

Thanks.

A quick guess from name of those undefine functions, I think you miss some file format process libraries/routines.

The Error 1 is from `make' and tells you the cc does not finish its job.

They are missing functions.

Your missing the support libraries for various output formats.

See: http://www.avatar.se/molscript/doc/links.html#libraries

If you cannot get or compile those libraries first, you need to somehow
tell the molscript compile to not use those formats.

Thanks for the replies.
The makefile that I am using is, according to the instructions, supposed to work without any installed external libraries.

From the installation instructions:

"However, the basic implementation of MolScript (with the PostScript, Raster3D and VRML 2.0 output modes) needs no external software, and is straightforward to compile. "

But I still get the above error when I try to complie.

Any other thoughts?

OK. Got it. I needed to reinstall the source folder and do the basic makefile. It worked fine.

Now I need to get Ghostscript installed so I can view PS files. This is providing to be more difficult...

I'm getting pretty far on compiling Ghostscript...I get caught when it looks for the X11 libraries. I can't find them and don't think they are part of X. Any ideas?

In case you're not aware, there's already a carbonized PostScript viewer out, called MacGhostView.

See www.kiffe.com/macghostview.html

Thanks Peter. That is very helpful. I had given up on compiling Ghostscript and was using Photoshop in Classic. This is much better, though.

I am trying to complie Rayshade now (to render the molecular output files from molscript).

The Configure file from Rayshade asks me where my C libraries are located... They are not in /usr/local or /usr/lib. Where are they kept?

Remove -lm from the LIBS line. OSX has this functionality without having the library.

This is no longer needed. OS X 10.0 still functions with -lms included, since it was such a pain to remove them all, but it might be linked against automatically, i don't know.

libm.dylib is a link to libSystem.dylib, and libSystem.dylib is again a link to libSystem.B.dylib.

It looks like functions that you might expect from -lm are included in libSystem.B.dylib.
