Hi


I can't cross compile openvpn with-crypto-library=polarssl according to https://community.openvpn.net/openvpn/w ... ericsubdir

Compiling without host parameter is fine.

anyway to cross compile openvpn with polarssl enabled?

Hi arium,

I can compile 2.3.1 with --host=i686-w64-mingw32 and --with-crypto-library=polarssl with the following flags: When I remove the -lpolarssl from the POLARSSL_LIBS, I get the same indefined reference errors you get.

What I also noticed, your POLARSSL_CFLAGS include dir (-I) seems to point to the openvpn include dir rather than the polarssl include dir. Finally, the -L in your POLARSSL_LIBS points to the libpolarssl.a file, whereas I believe the -L should point to the directory where the libpolarssl.a file resides.

Thanks for your help

Your reply helped me a lot.

Instead of "make && make install", I compiled polarssl with this command:
and now problem solved

I'm going to cross compile polarssl for openvpn x64 with:
I hope it's ok, if It's wrong please tell me.

Best Regards

I was able to compile openvpn in open-build script with:
