问题
I have written and compiled a MEX function to be called from a MATLAB routine, it runs great on my computer. However, when I try to have a different computer run my routine, it breaks with an error saying the module does not exist. My MEX function is referencing the GSL libraries, and some others. I want to know if it is possible to compile my MEX function so that is a standalone. When I say standalone I mean that if I just copy the MEX file to another computer, and there are no libraries or compilers installed, it will still work.
Thanks!

Your external libraries need to be static libraries. Then there are a number of ways to do it:
- add a '-static' linker flag when running mex (gcc option).
- instead of using '-lgsl' add '/path/to/libgsl.a' (Linux)
- or simply add the object files from the libraries you use in your mex files to the mex command
The mex file itself will still only run on a compatible system (64bit vs 32bit, matching libc version).
On linux, to check whether you have compiled correctly type 'ldd mexfile.mexext'. Your external libraries should not show in the list.
