Thanks for your help with the Xm/Xm.h problem. I've downloaded Open Motif and now have Xm.h on my disk. That solved that problem but now I have another one... Another file that is required for Alliance but I can't find anywhere, is the Xintl library. Therefore my attempts to compile Alliance are stuck at this point now: [...] make[1]: Entering directory `/opt/alliance-4.0.6/sources/dreal' /usr/bin/gcc -g -DLinux -o /opt/alliance-4.0.6/archi/Linux/bin/dreal GSB_share.o GSB_parse.o GSB_error.o GRD_rds.o GRD_window.o GRD_error.o GRD_undo.o GRD_select.o GRD_search.o GTB_icon.o GTB_panel.o GTB_menu.o GTB_pixmap.o GTB_cursor.o GTB_dialog.o GMX_motif.o GMX_color.o GMX_graphic.o GMX_panel.o GMX_menu.o GMX_message.o GMX_grid.o GMX_event.o GMX_cursor.o GMX_dialog.o GMX_view.o GMX_icon.o GMF_menu.o GMF_panel.o GMF_dialog.o GMF_file.o GMV_view.o GMV_panel.o GMV_menu.o GMV_dialog.o GMV_message.o GMV_map.o GMT_tools.o GMT_menu.o GMT_panel.o GMT_dialog.o GMT_message.o GMS_setup.o GMS_menu.o GMS_dialog.o GMS_panel.o GMC_create.o GMC_menu.o GMC_panel.o GMC_dialog.o GMC_message.o GME_edit.o GME_panel.o GME_dialog.o GME_menu.o GME_message.o GME_modify.o GME_search.o GME_select.o GMH_help.o GMH_menu.o GMH_panel.o dreal.o -L/usr/X11R6/lib -lXm -L. -L/usr/X11R6/lib -lSM -lICE -lXintl -lXt -lX11 -L/opt/alliance-4.0.6/archi/Linux/lib -lRtl110 -lRgs112 -lRcf111 -lRut208 -lRfm210 -lRpr213 -lRds209 -L/opt/alliance-4.0.6/archi/Linux/lib -lMpu406 -lMap406 -lMmg402 -lMcp407 -lMph410 -lMut325 -lm /usr/bin/ld: cannot find -lXintl So, where would I find Xintl.so? (Or is it libXintl.so?) I've found some FAQ that mentions Xintl and why it's required in some cases, but nowhere any hint where to get this library. Xintl seems not part of the standard Open Motif, Lesstif, Xfree86, or X distributions, unless I checked/downloaded the wrong files. As always, any help is very much appreciated. - Rolf -- Rolf Lochbühler <rolf@weitewelt.net>
