how to incorporate the libraries?

[rodrigoml]

hello, I m interested in intro to physics simulation, with the characteristic bullet libraries specially, on linux, but it is my first problem:

I done the installation procedure.. cmake, configure, make, make install (in this step, it copied the folders tree with .h libraries, "/usr/local/include/bullet").. but I cant compile my codes because gcc dont recognizes the bullet libraries! so, for example, any functional code with #include<btBulletDynamicsCommon.h> becomes non-functional (error to compile).

I appreciate any help for me. thanks for his works, i hope contribute.

Can you copy the error here? It might be easier for us to help if you do.

yes, here

little code, test.cpp:
#include <btBulletDynamicsCommon.h>
int main()
{
return 0;
}

compile:
rodri@dora:~/Escritorio/temporal$ gcc test.cpp -lBulletDynamics
test.cpp:1:36: error: btBulletDynamicsCommon.h: No existe el fichero ó directorio

(file does not exist)

I see, it's not even finding the headers.
In my code, I have:

Code: Select all

#include <bullet/btBulletDynamicsCommon.h>

Because all the Bullet headers are within the /usr/include/bullet directory, and normally GCC will just check /usr/include.

U thanks, I can compile now!!

#include <bullet/btBulletDynamicsCommon.h> --->

rodri@dora:~/Escritorio/temporal$ gcc test.cpp -lBulletDynamics
In file included from /usr/local/include/bullet/btBulletCollisionCommon.h:22,
from /usr/local/include/bullet/btBulletDynamicsCommon.h:20,

...........


so I directlly changed the bullet directory to the folder up, and use #include <btBulletDynamicsCommon.h>, and so compile without errors..

thank you very much.
I'm programming right now!

hello again, new problems:

it can compile, but the binary does not work

rodri@dora:~$ '/home/rodri/Escritorio/temporal/test'
/home/rodri/Escritorio/temporal/test: error while loading shared libraries: libBulletDynamics.so.2.77: cannot open shared object file: No such file or directory

I look for these libBulletDynamics.so.2.77 in the linux file system, but was not, I dont know, bad make intstall may be. Then I try coping the .so files generating for the make, in the libs folders into the linux file system, not work..

sorry for the delay, connection problem.

If you run 'ldd' on your executable, it will list the path where it expects to find each library it is attempting to load.
