Not building on OpenBSD

[pavanmishra]

Trying to build with

gmake HOST_ARCH=x86_64 HOST_OS=openbsd WITH_GMP_DIR=/usr/local

No rule to make gmp.h required by gc.o

I am running it on Virtualbox as a guest. From which its difficult to copy the errors from terminal. Tried with xsel but some parts are copied and some not.

That sounds like GMP is not installed. Can you confirm that /usr/local/include/gmp.h exists? I don't believe that GMP is part of a standard OpenBSD installation, so you may need to install it via an appropriate package manager.

Also, in most circumstances, you should not need to explicitly set HOST_ARCH and HOST_OS (or WITH_GMP_DIR, though that will depend on whether or not /usr/local/include and /usr/local/lib are on the default include and library paths).
