Hello everyone! :
I have some problems with the lib Genvis.
I downloaded the library from the cvs server of berlios
(http://cvs.berlios.de/cgi-bin/viewcvs.cgi/opensgplus/) and i put it
on the Opensg/Source/Experimental, and i followed rthe instructions to
put it on the OpenSG tree, but when i was compiling the test program
for the collisions (testCollision.cpp), i have a lot of errors (listed
at the end of the message, and the Makefile is listed too), can
anybody tell me why i have this errors? (Im working on Linux Slackware
10.0 kernel 2.4.26)
Well i hope somebody will help me!, Thanks!
(by the way... sorry if my english isn't pretty god...)
Ok, I try to :-)
Errors:
/X11R6/lib -o testCollision
/tmp/ccDBZ0Cd.o(.text+0x57a): In function `main':
/home/felipe/CAVE/progOSG/testCollision.cpp:100: undefined reference
to `genvis::OpenSGCache::the()'
/tmp/ccDBZ0Cd.o(.text+0x583):/home/felipe/CAVE/progOSG/testCollision.cpp:100:
undefined reference to
`genvis::OpenSGCache::setHierarchy(genvis::StaticInput<genvis::OpenSGTraits>*)'
<snip>
That is pretty much everything used in testCollision from Genvis...
Makefile:
# "opt" if you use the optimized library otherwise it is "dbg"
LIBTYPE ?= dbg
# set the path to the installed osg-config executable here
OSGCONFIG := /usr/local/bin/osg-config
# use osg-config to set the options needs to compile and link
CC = "$(shell $(OSGCONFIG) --compiler)"
CCFLAGS = $(shell $(OSGCONFIG) --cflags --$(LIBTYPE) Base System GLUT)
LDFLAGS = $(shell $(OSGCONFIG) --libs --$(LIBTYPE) Base System GLUT)
You do not link the GenvisLib at all.
So put "OSGGenvisD.lib" for DBG resp. "OSGGenvis.lib" for OPT into the
line LDFLAGS
LDFLAGS = $(shell $(OSGCONFIG) --libs --$(LIBTYPE) Base System GLUT)
OSGGenvisD.lib
# setting up the wildcard for *.cpp
TUTS := $(wildcard *.cpp)
PROGS := $(TUTS:.cpp=)
# program dependencies
default: $(PROGS)
# make rules
.PHONY: clean Clean
clean:
rm -f *.o
Clean: clean
rm -f $(PROGS)
%.o: %.cpp
$(CC) -c $(CCFLAGS) $<
%: %.o
$(CC) -o $@ $< $(LDFLAGS)
%: %.cpp
$(CC) $(CCFLAGS) $< $(LDFLAGS) -o $@
Hope it helps,
Christoph
