+ | DESCRIPTION |
+ Guys:
+
+ Because your object files are stored in a different directory and you use suffix
+ rules to build the object files make (gmake) fails to find the target and figure
+ out that it has been built and is up to date, hence rebuilding it every time you
+ do make.
+
+ Here's a patch that uses 'vpath' to fix this common problem with GNU make, the
+ file patched is src/Makefile.incl and it should work on all (Unix) platforms.
+
+ === Begin patch
+ *** src/Makefile.incl Wed Mar 21 13:43:12 2001
+ --- src/Makefile.incl.patched Wed Mar 21 13:53:24 2001
+ ***************
+ *** 394,399 ****
+ --- 394,402 ----
+ .SUFFIXES:
+ .SUFFIXES: .cpp .c .$(TO)
+
+ + # Tell make where the object files are for proper resolution of suffix rules
+ + vpath %.$(TO) $(XML_OBJ_DIR)
+ +
+ .cpp.$(TO):
+ $(CC1) -c $(XML_BUILD_OPTIONS) $(XML_DEF) $(XML_INCL)
+ $(EXTRA_COMPILE_OPTIONS) -o $(XML_OBJ_DIR)/$(@) $(<)
+
+ === End patch
+
+ Thanks!
