Disney Dynamica Bullet 2.76 not compile-Ubuntu 10.04 64-bit

[mrplatzangst]

Hi there,

I already posted in this thread, that I couldn't compile the plug-in successfully.

Now I realized, that it was definitely the wrong location. It has to go inside this forum!

I will continue the discussion here.
It would be nice if someone could join the threads.

So..
Again, my error message:

Code: Select all

A friend of mine advised me to add #include <stdio.h> to the bt_solver.cpp file.
...like this:

Code: Select all

#include "LinearMath/btSerializer.h"
#include "bt_solver.h"
#include "../BulletColladaConverter/ColladaConverter.h"
#include <string.h>
#include <stdio.h>

I decided to give it another try.

Code: Select all

make clean && cmake . -G "Unix Makefiles" && make

After some more successful compiling, it stopped here:

I think it tries to tell me to recompile something with -fPIC.

I tried the following code:

Code: Select all

export "CC=/usr/bin/gcc-4.4 -fPIC"; make

...same errors

Any ideas?
Do you need additional information about my system? Tell me

Greetings!

Looks like you are using an out-of-date source tree, where and when did you get it?

That #include <stdio.h> was already fixed back in April 2010.
Also the -fPIC issue was fixed.

Can you please download the latest revision 41 from http://code.google.com/p/dynamica/downloads/list (or svn trunk) and see if that helps?
Thanks,
Erwin

Hey Erwin,

thanks for the reply!

Ironically I did get the sources from the same website a few days ago. At least I think so.

These issues are fixed? This sounds awesome!
Now I definitely give it another try

I will keep you updated!

Greetings

EDIT:
I have downloaded the new code in revision 41 and the compiler still has problems

Code: Select all

unzip dynamica-src-rev41.zip
cd dynamica-src
cmake . -G "Unix Makefiles"
make

Then I get this:

There is still this -fPIC error. Just in a different file.

After some googling I found this article in the Gentoo Linux Documentation.
http://www.gentoo.org/proj/en/base/amd6 ... t=1&chap=3

It is about fixing -fPIC errors. In my case it recommends to recompile libXML.a with -fPIC enabled.
I'd love to do this, but how?

Greetings!

[Erwin Coumans]

Currently we only add the -fPic for C++ files but LibXML has C files.

Can you edit CMakeLists.txt in the Dynamica root directory, and add the following red lines around line 16, and see if that helps?

IF (UNIX AND NOT APPLE )
ADD_DEFINITIONS(-DBUILD_SHARED_LIBS=ON)
OPTION(BUILD_FPIC "Build Linux/Unix version using -fPIC" ON)
IF(BUILD_FPIC)
SET( CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -fPIC" )
SET( CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -fPIC" )
SET( CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -fPIC" )
SET( CMAKE_C_FLAGS_DEBUG "${CMAKE_C_FLAGS_DEBUG} -fPIC" )
ENDIF(BUILD_FPIC)
ENDIF()

Thanks,
Erwin

Thank you very much Erwin!

The plugin compiled without errors and it works!
You just made my day

The only weird thing was the installation of the plugin itself. The README told me to run make install. But there was no make install target in the Makefile. I ended up copying the files into the right place by hand.

Greetings!

[Erwin Coumans]

Thanks for the feedback and testing.

The README is out of date and assume using the Makefile instead of CMake.

Thanks,
Erwin

I have been waiting for someone to compile Dynamica for linux for a very long time. Could you please post your working plugin? Or at least explain how to make one to someone without a lot of programming experience.

I am using Cent OS with maya 2011


thank you!!
