Could you please include `mipsle` in releases?

[missingcharacter]

I see https://github.com/grafana/agent/pull/602

For now, I'd like to not bundle it with releases. New platforms really bloat up the CI time, and I'd prefer to wait until we have more people asking for it before we do that.

Could you have people show their interest in mipsle in this issue?

We have a use case to install Grafana Agent on hundreds of OpenWRT based routers, these devices are based on MIPS architecture. Currently we are building our own, It would really helpful to get Grafana Agent release supported for MIPS.

Hi @rfratto 👋

Would really appreciate your attention on this.

[ksingh-scogo]

@missingcharacter did you manage to find a workaround on this topic.

[missingcharacter]

@ksingh-scogo Yes, I manually build agent and agentctl with GOOS=linux GOARCH=mipsle GOMIPS=softfloat

[missingcharacter]

@ksingh-scogo I did it in an older version, but I believe the following should work

Requirements:

• docker should be installed
• Propagate GOMIPS environment variable

The actual commands

$ export GOOS=linux GOARCH=mipsle GOMIPS=softfloat USE_CONTAINER=1
$ make binaries

and if it doesn't work you can try to go back to this version https://github.com/grafana/agent/pull/602/files

[missingcharacter]

welp, newer versions don't even support mipsle, I get these errors when building:

with CGO_ENABLED=1

$ export GOOS=linux GOARCH=mipsle GOMIPS=softfloat CGO_ENABLED=1 USE_CONTAINER=1
$ make binaries
...
fatal: unsupported $VICEROYARCH mipsle for linux. Must be one of: amd64, 386, arm, arm64, ppc64le, s390x

you'd have to git checkout to a previous version like https://github.com/grafana/agent/pull/602/files

[missingcharacter]

seems like mipsle is not supported by https://github.com/rfratto/viceroy/issues/6

[missingcharacter]

Trying to add mips support here https://github.com/rfratto/viceroy/pull/7

@ksingh-scogo if you are interested in an "easy" way to build the agent and agentctl binaries, sadly, these would be for an older version. Try the below:

$ git checkout b8ec553
$ CROSS_BUILD='true' BUILD_IN_CONTAINER='true' RELEASE_BUILD='true' TARGETPLATFORM='mipls' make all
...
