yes, no doubt about it: it is to be avoided, unless you are really motivated!
You have an extremely hacked application driver in pre-alpha state for an abandoned video grabber that has never seen a half source released by the company that marketed it, nothing has been documented and the only thing available comes from the reverse engineered binary-only driver (for Windows) , which helped create a couple of experimental source files written in GoLang, a language for which you don't have a compiler for your hardware because PA-RISC is not yet supported by llvm, so there is no GoLang compiler.
This is the scenario. What is this? ... love? for information technology? or just bloody masochism?
I don't know, but I'd really like to support this (crazy) idea, so ...
... any advice on how to convert GoLang to C?
Because, to make matters worse, I don't know GoLang at all.
---> yup, going to reverse engineer a reverse engineered hack in alpha-state for an abandoned hardware, supporting an experimental abandoned architecture
I can not do it, or can I?
