Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

This is a problem that needs to be fixed in gccgo's Go library.

[YallaPayInc]

how please ?

Change https://go.dev/cl/486576 mentions this issue: syscall: add prlimit

[ianlancetaylor]

@YallaPayInc You'll have to patch and rebuild gccgo's libgo library. The fix is https://go.dev/cl/486576.

i uploaded patch file on project directory but still error exist

[ianlancetaylor]

@YallaPayInc To be clear, you are using gccgo, which is not the usual Go compiler. In order to use the patch, you will have to build and install a new version of gccgo. If you have not done that before, that is a difficult job. But if you have done that before, are you sure that you want to be using gccgo? Perhaps you should be using the default Go compiler, which is known as gc.

i have path for gcc under usr/lib so is this correct path to add patch file for fix issue ?

[ianlancetaylor]

In order to apply the patch you must download the GCC sources, you must apply the patch to the GCC sources, and you must rebuild and reinstall GCC.

If you have not done this before I do not recommend doing it today. It is difficult.

@ianlancetaylor I assigned this to you in triage, assuming that your CL is the fix and will close out the issue.
