Cannot currently build stoken about stoken HOT 4 CLOSED

The libtomcrypt RSA library functions used to compute BatchSignature want the caller to specify which math library should be used for big number arithmetic. There is some information on this in crypt.pdf under Math Descriptors and in the RSA example program.

Are you seeing an error at compile time or link time? If the latter, you could try linking with -ltommath to see if that helps. Perhaps my build configuration isn't quite right.

Or, maybe the libtomcrypt installation on your system uses a different math library. This could be worked around by adding checks to configure.ac: maybe try different a few different math library backends, or perhaps switch to nettle if the tomcrypt ltm_desc check fails.

Are you using a tomcrypt package from a specific distribution/version, or is it self-installed?

The issue was in the distribution (ArchLinux) build/release of the libtomcrypt package. I've submitted a request to have that updated by adding the Math Descriptor definitions during compilation. Thanks for the pointers.

I just pushed nmav's nettle support patches to master. Intended behavior: if libtomcrypt isn't usable (either missing entirely, or we can't figure out how to set up bignum arithmetic) stoken will try to link against nettle instead.

Do you want to give it a shot and see if this works on your setup?

Confirmed working when using libtomcrypt without libtommath. Thanks.
