Hello, I need access to the latest gcc compiler for some experimental work with some GPU enabled coding. [1,2]
So using this latest gcc compiler just for compiling some fancy new cluster codes using RDMA, is liable (probably ?) to be a wee bit tricky. Now, assuming I find an overlay somewhere, how do I go about ensuring it is slotted and only used with specific syntax just for a few codes and nothing on my general portage tree? Also, I have not found a gcc-5.0 or gcc-5.1 in an overlay (yet), but I did find this gcc-9999 by zorry[3]. It does not look to be gcc-5.x but I am as yet uncertain on that. Any discussion or suggestions how to best get access to gcc-5.x is most appreciated; as is methods to using it (control it) limited to just a few codes.
