It doesn't come with debian (i wrote it), it simply echoes

-I /usr/lib/ocaml/3.07/camlimages ci_core.cma ci_gif.cma ci_jpeg.cma 
ci_tiff.cma ci_bmp.cma ci_ppm.cma ci_png.cma ci_ps.cma ci_xpm.cma

as in

#!/bin/sh
LIBDIR=/usr/lib/ocaml/3.07/camlimages

echo -I $LIBDIR ci_core.cma ci_gif.cma ci_jpeg.cma ci_tiff.cma 
ci_bmp.cma ci_ppm.cma ci_png.cma ci_ps.cma ci_xpm.cma

It fails on xvthumb, but if I take that out it links ok. :?

ocamlc -custom -verbose `camlimages-config` -cclib "-L/usr/X11R6/lib 
-lXpm -lX11 -lpng -lfreetype -ljpeg -lgif" monochrome.ml
+ gcc -Wl,-E -o 'a.out' -I'/usr/lib/ocaml/3.07' -L/usr/X11R6/lib 
-Wl,-rpath,/usr/X11R6/lib /tmp/camlprim88d632.c 
'-L/usr/lib/ocaml/3.07/camlimages' '-L/usr/lib/ocaml/3.07' '-lci_xpm' 
'-lXpm' '-lci_png' '-lpng' '-lz' '-lci_tiff' '-ltiff' '-lci_jpeg' 
'-ljpeg' '-lci_gif' '-lgif' '-L/usr/X11R6/lib' '-lXpm' '-lX11' '-lpng' 
'-lfreetype' '-ljpeg' '-lgif' -lcamlrun -lm  -ldl -lcurses -lpthread

with -lxvthumb, it gives an error saying it can't find the lib (it's not 
on the system).

Also if -custom is removed it fails.

Yeah I know.  It's just that if I wanted to read xpm images, I'd have 
had a problem.


Thanks,
