".mexa64: cannot dynamically load executable" problem

I am compiling a mexa64 file in Ubuntu 12.04 with matlab 2013a. I used gcc, g++, gfortran, all with version 4.6.3. I can compile it without showing error, and get the .mexa64 executable. However, when executing the executable, the above error message shows up:

-----------

"Invalid MEX-file '/home/lxzhu/cas2d/src/caspol2d.mexa64': /home/lxzhu/cas2d/src/caspol2d.mexa64: cannot dynamically load executable"

-----------

I used the ldd command to check the dependency, which is shown as follows and seems fine:

I have also set the LD_LIBRARY_PATH to include all the directories including the shared object files:

-----------

>> getenv LD_LIBRARY_PATH

ans =

/opt/MATLAB/R2013a/sys/os/glnxa64:/opt/MATLAB/R2013a/bin/glnxa64:/opt/MATLAB/R2013a/extern/lib/glnxa64:/opt/MATLAB/R2013a/runtime/glnxa64:/opt/MATLAB/R2013a/sys/java/jre/glnxa64/jre/lib/amd64/native_threads:/opt/MATLAB/R2013a/sys/java/jre/glnxa64/jre/lib/amd64/server:/opt/MATLAB/R2013a/sys/java/jre/glnxa64/jre/lib/amd64:/opt/MATLAB/R2013a/bin/glnxa64:/usr/lib:/opt/MATLAB/R2013a/sys/os/glnxa64:/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu:/lib64:

-----------

I have also tried to adding '-fPIC' to CFLAGS, CXXFLAGS, FFLAGS, CPPFLAGS in the configure stage, and adding the '-shared' option in the linking stage, but the error persist.

I have tried in another linux machine, and the same error appears. Besides, I have compiled this in macosx 10.8, by modifying some surfix, and file formats, and that can compile successfully. I can also run the executable successfully and produce the required simulation result. So I guess, I might have compiling and linking issue in the linux case.

Hope someone here can provide some hints about what is wrong with it.

Suggestion will be greatly appreciated.
