Description

I use gitea on a shared hoster environment and compiling gitea from source. threads-per-user are limited to 300. Sometimes i got following error while make build for multiple modules:

runtime: failed to create new OS thread (have 7 already; errno=11)
runtime: may need to increase max user processes (ulimit -u)
fatal error: newosproc

I try to limit the threads by make with

make generate build -j2

but the result is the same. Is it possible to limit threads/processes while compiling?

use EXTRA_GOFLAGS="-j2" make generate build

I will give it a try thanks :)

Seems not to work. I try TAGS="bindata" EXTRA_GOFLAGS="-j1" make generate build but sometimes i get the same error:

runtime: failed to create new OS thread (have 14 already; errno=11)
runtime: may need to increase max user processes (ulimit -u)
fatal error: newosproc

Otherwise i can see the line

go build -i -v -tags 'bindata' -ldflags '-s -w -X "main.Version=1.1.2" -X "main.Tags=bindata"' -o gitea

TAGS are applied to the go build but -j1 is missing. Is it normal?

just add -j1 in this line then https://github.com/go-gitea/gitea/blob/master/Makefile#L23

Ok Makefile included in 1.1.2 not use GOFLAGS and EXTRA_GOFLAGS. WIll this changes merged to next releases?

yes, it will be in 1.2.0 when it is released

Sounds good, thanks for clarification.

-j is no legal option for go build :( Luckily you can use GOMAXPROCS=2 to limit the os threads :) Maybe you want add this to the build documentation?
