I applied a patch for golang/go#62440 (02e7122 and eed5a7f) for Go 1.21. Now the authentic change will be merged for Go 1.21.4 (golang/go#63209), so our hack will no longer be needed.

open C:\Program Files\Go\src\os\rlimit.go: The system cannot find the file specified.

The file rlimit.go was moved at https://go-review.googlesource.com/c/go/+/478659.

• gccgo12 already supports Go 1.18 (https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=libgo/VERSION;h=39560f0fcdd63e4bb8eead6a3f849e91636d31eb;hb=2ee5e4300186a92ad73f1a1a64cb918dc76c8d67)
• Debian stable already supports Go 1.18 (note that Ubuntu stable supports Go 1.15 by default...)
• The Go team no longer supports Go 1.17 and older, as we know

@TotallyGamerJet what do you think? Are there extra tasks for this?

Some environments might have a different page size than 4096.

golang/go#67401

Some platforms don't offer mmap/munmap, but might offer counterparts. For such platforms, let's add a new option to enable hooking.

Now syscall 278 (getrandom) is missing.

I found signal.h is not available in some special environments (amd64).

On the latest commit, the title message appears when running example/helloworld/run.sh.
/usr/lib/go-1.19/src/syscall/ has indeed no file named rlimit.go, but it can be found in /usr/share/go-1.19/src/os/rlimit.go.

worth noting i am using amd64 (not trying to run just yet, i'd prefer compiling outside a VM)
Config:
debian 12 up to date
golang-1.19-go/stable,now 1.19.8-2 amd64

full output:
