Hi all, please help me solve that error:

Thanks for helping ...

Just add -fPIC to your Makefile or where the build settings are specified.

Thanks again) I will try

looks like hcustom have used this option on compile time:

i check that with "-c" option:

hcustom -c

-DVERSION=\"11.0.813\" -D_GNU_SOURCE -DLINUX -DAMD64 -m64 -fPIC -DSIZEOF_VOID_P=8 -DSESI_LITTLE_ENDIAN -DENABLE_THREADS -DUSE_PTHREADS -D_REENTRANT -D_FILE_OFFSET_BITS=64 -c -DGCC4 -DGCC3 -Wno-deprecated -I/opt/h11/toolkit/include -I/opt/h11/toolkit/include/htools -Wall -W -Wno-parentheses -Wno-sign-compare -Wno-reorder -Wno-uninitialized -Wunused -Wno-unused-parameter -O2

?

That indeed is already in there. From what repository did you check out the source code? I'll try compiling it here if I get the time.

Bullet from there: http://code.google.com/p/bullet/downloads/list

i have not ideas what i can do with that error... Something is wrong with btSequentialImpulseConstraintSolver.o or it's src code.. I think i need Bullet DOP some developers help and attention, may be something versions mismatch...

Sad.

Sorry it took some time. Trying to finish up my thesis. Anyways the problem is that bullet itself aint compiled with -fPIC.

You can fix this by when creating your makefiles for bullet use

cmake . -G "Unix Makefiles" -DCMAKE_CXX_FLAGS="-fPIC" -DCMAKE_C_FLAGS="-fPIC"

instead of the regular

cmake . -G "Unix Makefiles"

After that it compiled fine here. I also used http://gitorious.org/~almatea/bullet-physics-solver/almateas-bullet-physics-solver instead which seems to be a slightly more recent fork but i think it should work with the regular one as well.

System specs for my machine:

Linux Mint 11 (Ubuntu 11.04) 64bit

Houdini 11.0.733

Bullet 2.78

Thanks !

Today i have found another solution, all works but i'm on testing stage.

cmake . -G "Unix Makefiles" -DBUILD_SHARED_LIBS=ON -DBUILD_DEMOS=OFF

after that i can compile all what i need..

Now i test DOP and have some troubles. But this is for another thread

Thanks Erik_JE !

No problem, good that you got it working. It will be great with the native bullet solver in H12.
