 |
|
Hi!
I am trying to compile a go program in gentoo using the following flags:
| Code: | export CGO_LDFLAGS="-static -Wl,--fatal-warnings"
CGO_ENABLED=1 go build -o build/fail-over-agent cmd/fail-over-agent/main.go |
But I am seeing the following error:
| Code: | # command-line-arguments
/usr/lib/go/pkg/tool/linux_amd64/link: running x86_64-pc-linux-gnu-gcc failed: exit status 1

From googling around, it seemed that recompiling glibc with static-libs enabled should solve the issue , but it's not.
I have added static-libs to /etc/portage/make.conf and re-built glibc.
(It seems this the default btw)
Any idea how to overcome this error? |

Do you actually need to use cgo for building? If not just try
| Code: | | CGO_ENABLED=0 go build ... |
Also not seeing any actual error in the output other than the summary, only warnings. The warnings all relate to functions using NSS which uses dynamically loaded plugins using dlopen, which can cause problems when using static linking. If you don't know what NSS is, you probably won't need it (and therefore also won't need cgo). |

This is not correct, in multiple ways. First, you rarely need or want USE=static-libs, so you should use package.use to set it only on those packages where you cannot avoid it. Second, USE=static-libs is not the default on any standard Gentoo profile I know of. Third, I think enabling glibc static libraries is not the right way to resolve the shown warning. |
