musl binary is not statically linked

[dufferzafar]

I downloaded the latest musl binary from GitHub releases, but am unable to run it.

Your ldd output says that musl libc is not installed in your system.

[dufferzafar]

@rhysd But I've never needed it before with other application's musl build. I thought the point of musl was to create a statically linked binary that works anywhere?

[rhysd]

OK, I understood your point. I'll change the title.

Can you download binary from the following link and check if this issue was fixed on your side?

https://github.com/rhysd/hgrep/suites/6685740113/artifacts/253610627

[dufferzafar]

Yes it works! What did you change on your end?

I was facing this error with another rust app as well: jmacdonald/amp#255

[rhysd]

This is the change:

f228502

I noticed that -crt-static prevents linking libc statically. I just removed it and rebuilt release binary.

v0.2.6 was released
