Hello world issues

[charles_west]

Hello,
I'm a newbie trying to get the hello world program (http://www.bulletphysics.org/mediawiki- ... ello_World) to compile. I'm using gcc with ubuntu 8.10. I seem to have a problem similar to that discussed here: http://bulletphysics.org/Bullet/phpBB3/ ... f=9&t=3747 but I do not know how to fix it. I ran cmake -G"Unix Makefiles" then make but the readme in bullet-2.75/lib says:

At the moment there are no binary packages from Bullet library.

Once this is done, 3 libraries will be placed here:



bulletmath.a

bulletcollision.a

bulletdynamics.a



The C-API will be available in the include folder.



For now, there is only C++ files, see src/btBulletCollisionCommon.h and src/btBulletDynamicsCommon.h

What should I do to try to get the libraries to compile correctly?

Thank you for your time.

[Erwin Coumans]

Have you tried to compile the Bullet demos, and afterwards do a grep/search in all Bullet directories for .a (or under Windows .lib) files?

Thanks,
Erwin

[charles_west]

Sir,
The demos compiled fine. When I ran the search, the libraries showed up in the src folder.

I ran sudo make install again and the output is as follows:

collect2: ld returned 1 exit status

It seems like it is finding the libraries, but it can't resolve the references?
Thanks.

[pxq]

try command like this:
g++ -o test main.cpp -llinearmath -lbulletcollision -lbulletdynamics

NOTE:
1) -L mean library path, and -l is the library name.
2) link linearmath first, bulletcollision second, bulletdynamics third, it seem like the linker not solved the lib dependence. (i dont know, just try it)

hope it help.

[charles_west]

I gave it a shot using:
g++ -o test main.cpp -llinearmath -lbulletcollision -lbulletdynamics

but it couldn't find the linear math library (though it is in usr/local/lib/):

/usr/bin/ld: cannot find -llinearmath
collect2: ld returned 1 exit status

Thanks

NOTE:
1) -L mean library path, and -l is the library name.
2) link linearmath first, bulletcollision second, bulletdynamics third, it seem like the linker not solved the lib dependence. (i dont know, just try it)

hope it help.

i noticed that, your bullet install log, the files you installed is:
libLinearMath.a
libBulletCollision.a
libBulletDynamics.a

so, your command is like:
g++ -o test main.cpp -lLinearMath -lBulletCollision -lBulletDynamics
or:
g++ -o test main.cpp -lBulletDynamics -lBulletCollision -lLinearMath

in linux, file "a.txt" is difference with "A.txt"

YES!

The first one didn't work, but the second one did. It compiled with no errors and ran without problems.

Thank you, that really helps!
