I found that if you add linux-headers to the apk install command, libressl will build fine :)

Thanks!

Hello guys,

While searching for the same error message, I landed up on this message. I am seeing the same error on Travis CI which runs Ubuntu 14: https://travis-ci.org/kaushalmodi/hello_musl/builds/440319409#L1332.

I installed sudo apt install linux-headers-$(uname -r), but that didn't help. Would you guys be able to help out?

I need to compile static libressl with musl.
