[X-Motif] Linking order of X libraries
SYMPTOM/SOLUTION TEMPLATE:
PRODUCT: X Motif
OP/SYS: Linux Fedora Core 6
COMPONENT: X libraries
SOURCE: Philippe Vouters Fontainebleau/France
LOW-COST HIGH-TECH: http://techno-star.fr
SYMPTOM(S) or PROBLEM(S): On Linux Fedora Core 6, linking -lXt -lXm -lX11 causes the following run-time message: $ make -f makefile cc -c -w -g testy.c cc -o testy testy.o -lXt -lXm -lX11 $ ./testy Warning: XmManager ClassInitialize: XmeTraitSet failed Error: attempt to add non-widget child "DropSiteManager" to parent "testy" which supports only widgets
SOLUTION or COMPAQ RESPONSE: Change the link order to -lXM -lXt -lX11
ANALYSIS: This error is usually a result of using the Xt VendorShell instead of the Xm VendorShell, caused by linking ... -Xt -lXm -lX11.
