How to compile GCC on x86 for Sun4v?

Question

I am writing a programming assignment using C ++. The instructor for this course requires that all code be compiled and run on a UNIX server. The server is a SunOS machine. I wrote all my code on my personal laptop with GCC 5.2, which supports most of the functions of C ++ 11. However, when I upload my code to the server and try to compile it, I suddenly found that the version of g ++ on the server is 4.2.1, released in mid-2007. Many of the features of C ++ 11 are not supported. Even the argument is -stdnot accepted.

I tried to download the source code of the latest GCC and compile it on the server. Unfortunately, the disk quota is limited to 500 M per account. I'm just wondering if it is possible to cross-compile GCC on my x86 machine and upload the binary to the server so that I can compile my C ++ code.

By the way, I contacted the IT department for software updates, but they replied that they did not have such plans in the near future.

I did cross-compilation research online and found a couple of tutorials. But they are not easy to follow. In addition to binaries, there are also many dependencies such as headers and libraries. So before I give up and change my code to fit the old compiler, can anyone give me some suggestions?

Thanks.
