I have tried compiling the software for minsoc under the Ubuntu pre-compiled toolchain.
This results in the following error when compiling the support code:

/opt/or32-elf-1.0rc1/bin/../libexec/gcc/or32-elf/4.5.1-or32-1.0rc4/cc1: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory

However on a different machine when using a toolchain that I compiled from source, the above compilation goes through. Any ideas why?

That's a shared library failing to be found.

GCC requires the GMP, MPFR and MPC libraries to run.

Try:

Thanks that worked out.

Now I was trying to update the adv_jtag_bridge.
After modifying the Makefile (using the sed command), the make command fails:

cable_xpc_dlc9.c:24:35: error: usb.h: No such file or directory

Apart from this there are a few other errors but they will mostly get resolved if this one is. Any fixes?

The default configuration for adv_jtag_bridge includes support for USB cables. Either you don't have libusb installed, or it's not where adv_jtag_bridge is expecting it. If you haven't installed libusb, do so (probably something like 'sudo apt-get install libusb-dev', but I'm not certain). If you have installed it, find where it put usb.h, and add that to the include paths defined in the Makefile. If you're compiling the driver for the Xilinx XPC DLC9, you'll also need libftdi.

Alternately, if you're going to use a parallel JTAG cable, you can edit the Makefile and set support for USB cables to false.

This is not directly related to MinSoc but I am trying to compile or32-elf-gcc and am getting the same error as stated above.

I used to command given in the response:
sudo apt-get -y install libmpfr-dev libgmp3-dev libmpc-dev

and get the following response:

libgmp3-dev is already the newest version.

Which I am assuming means it has all of the latest packages. I cannot seem to figure out why I am still getting the error
