I'm using the include: < openssl/md5.h > in my c code. When I compile it with "gcc" compiler I don't have any errors, but when I compile it with cross compiler "arm-linux-gnueabi-gcc" I have the following error:
/usr/include/openssl/e_os2.h:56:33: fatal error: openssl/opensslconf.h: No such file or directory
compilation terminated.
I think that this error is because I don't have the openssl libraries in the cross compiler folder "/usr/arm-linux-gnueabi-gcc".
Can anyone say me if is this the cause of the error? And how I can install the openssl libraries for cross compiler?
I'm starting in cross-compiling, and I don't have much knowledge about this. Thanks for your time!

Cross-compilation is the act of compiling code for one computer system (often known as the target) on a different system, called the host. It's a very useful technique, for instance when the target system is too small to host the compiler and all relevant files.
A cross compiler is useful to compile code for multiple platforms from one development host. Direct compilation on the target platform might be infeasible, for example on embedded systems with limited computing resources. Cross compilers are distinct from source-to-source compilers.
In my case, exactly the same error message (but I was compiling in 32 bits on a 64 bits machine). I solved this with installing another architecture:
apt-get install libssl-dev:i386
