check-gmp always fails, even though gmp is installed (Cygwin)

[kernaltrap8]

Hello,
Im trying to install the toolchain to build PSL1GHT. I don't dual boot, so im using Cygwin since it's open-source. When running toolchain.sh in bash, it runs for a bit and then says this:

I have GMP installed, I even broke Ruby to install it.

Any help is appreciated,
James

I don't use Cygwin (I don't dual boot either :), but I suspect the libgmp-devel package is the one you need.
https://cygwin.com/packages/summary/libgmp-devel.html

If you end up with a list of Cygwin packages you needed to install, I'm sure we could add it to the readme to help other Cygwin users.

Hello,
Seems installing libgmp-devel fixed the gmp issue, but now it gets stuck on libelf

So, since you got the same problem with libelf that you got with gmp, maybe you should try the same solution (install the -devel package)? Just a thought...

yup, seems installing the devel packages of the dependencies works. add to the readme that Cygwin users must install the devel packages as well as the other dependencies.

now i got another issue.

well, the error is clear, you need to set the $PS3DEV environment variable before running the script.

You can: export PS3DEV=/usr/local/ps3dev
or try running toolchain-sudo.sh
