All the other files in the Alliance distribution have compiled successfully. I believe during the dreal make, gcc is looking for two files that I do not have: libXt.a, and libX11.a. I do have very similarly named files in my X11 lib directory called libXt.so and libX11.so but the only *.a files are libFS.a, libMrm.a, libXau.a, libXdmcp.a, libXm.a, libXpm.a, liboldX.a, and libxkbfile.a. I don't know much about X, but could any of these files contain the functions that dreal needs? My powerpc.mk file uses X11_LIB=/usr/X11R6.3/lib which is the directory containing these lib files. Thank you for any help you can give. *.so are dynamic libraries *.a are static libraries So you'll have to compile "dreal" in a dynamic format. Try "cc -Bdynamic ...." or "cc -dynamic ....", this give the linker "ld" switches to link dynamically. To do this try to edit the file Makefile and search for CC. -- Regards, Olivier. ==================================================================== Olivier SIROL Alliance Team ASIM/LIP6/UPMC Coul. 55-65, 2e etg, Bur. 213 75252 Paris Cedex 05 mailto:Olivier.Sirol@asim.lip6.fr Tel: (33/0) 1.44.27.30.43 http://asim.lip6.fr/alliance/ Fax: (33/0) 1.44.27.72.80 --------------------------------------------------------------------
