How to fix error: python cannot open cross compiled shared object file?

2 New Member
Hi,
Iam trying to build crda agent module on a cross platform(ARM).
To build the same, one of the input module is m2crypto shared object file.
I have sucesfully cross compiled and m2crypto.so file has been generated.

when I give the make command, python script is called internally which should
take m2crypto.so module as input and should generate openssl(RSA) keys.

The problem Iam facing is the python script could'nt import any of the modules from the __m2crypto.so file.
the error iam getting is
-------------------------------
$ make

GEN keys-ssl.c
Trusted pubkeys: /home/tools/crda/pubkeys/linville.key.pu b.pem
Traceback (most recent call last):
File "./utils/key2pub.py", line 6, in ?
import m2crypto
ImportError: /usr/lib/python2.4/lib-dynload/m2crypto.so: cannot open shared object file: No such file or directory
make: *** [keys-ssl.c] Error 1
--------------------------------
where as, when I compile m2crypto for host machine(x86 platform) and try to build the crda for the same,
python is able to import the m2crypto.so file.

Any suggestions on how to build it successfully on the different platform(ARM).

Thanks in Advance,
Rams ch

Are you using Python2.4 on a 32 bit computer? If not, find the Python installation. Start with /usr/lib and /usr/local/lib, and then a symlink to /usr/lib/python2.4 would probably be the simplest solution.

Yes Iam using Python2.4 on a 32-bit machine.
I tried using symlink but of no avail.

My doubt is Should I build python for class platform(ARM)? so that it can read the .so file compiled for the same.

I think you have to in fact, but you should emulate it on your PC first and work out the bugs http://www.crosscompile.org/static/pages/Python.html

Suppose I have defined a templete function prototype in a header file and the body in .cpp file and created executable without actually calling the templete function. Now let say from that executable I am loading a shared object and executing(dlsym-ing) some f() function, which inside calls the templete function. (Of course the header file with templete prototype is included in shared object source file, so it could be compiled.)

I need to call a function in a shared object with this signature: init_dialog(FILE *input, FILE *output) The FILE*'s are to stdin and stdout. The call from python is libdialog.init_dialog( x, y) I need to define x and y so that they will have the structure of sys.stdin and sys.stdout; the called function (init_dialog) is using a (std?) function fileno to extract the fileno from the FILE* describing stdin and stdout. How can I do this?
