Hi Ard, Thanks for your help. I had attempted to do something similar before for klibc package. There were few hurdles 1. I could not increase the disk size of the foundation model (didn't know how to do that. Could not find anything on the manual) and I needed larger disk space to first compile linux headers. May be for gmp I will not need that. 2. I was having trouble accessing internet from inside the foundation model and was running into difficulties copying files into the model, i.e. I could mount my build machine files from inside the foundation model but not the other way round. I remember struggling with this for few days before I settled with having all the code sit on the build machine and mounting them from inside the foundation model. This worked fine for the klibc package. Now this gmp package simply takes too long to build natively on the foundation model, so i was doing cross compiling to aarch64 equivalent of the MPN primitive functions. But now that I am done with that I would like to test and debug the code, so need something faster.
I will still give what you suggested a try. If I don't succeed, may be I will have to simply find a faster server where the foundation model is faster. let me know if you have any other ideas.
