Hello. I have been presented an interesting challenge from someone who is trying to work with some very specialized equipment. He is attempting to migrate off a bunch of legacy equipment hosted with Windows and onto a Red Hat based platform where we can update much of this bulky legacy code. I am trying to help out where I can. The current sticky bit is the fact that we need a C compiler for the 1750A microprocessor. In our research we have found many many many dead ends. We did discover a source download for a Windows gcc version that we were able to successfully compile and run the binary exe's under Wine. While it works as a proof-of-concept, it is really slow and unsuitable for our needs. We decided that if we were to have any hope of getting this to work, we should use the tools that were available at the latest support release. So for the time being, we are working on a CentOS 2 install with the gcc 3.1 source file. We have overcome many of the obstacles but the latest roadblock is simply over our heads at the moment and we are not finding much online. I have pasted the make error at the end of the email. I don't expect someone to solve our problems from it, but hopefully it helps to see part of the issue we have run into. I can go into more details as to what we have done but I first thought it worth asking if there are any GCC Guru's out there who might be able to help us out with the 1750A. Is there anyone who might be able to help us get this cross compile working? Or maybe know someone that might be able to help us?
