I have couple of queries:
I am trying to cross compile NGINX for powerpc. From what I read over internet, I figured out that we just have to specify the path of the toolchain and arch in the environment variables CC & ARCH respectively.
Followed by running ./configure --with-openssl=./openssl
and
make
But when I am runnning the configure command, I am getting the error:
./configure: error: C compiler ...../powerpc-linux-gnu-gcc is not found

I use the same tool chain for cross-compiling my other tools as well and didn't faced this kind of issue.

The other thing which obtrused me is the MARCO "NGX_THREADS".
I am really trying to find out its usage, and how to compile NGINX with it.(Does it actually compiles it in thread mode ??)
