What did you do?

cd examples/vweb

v -os linux .
Cross compilation for Linux failed (first step, cc). Make sure you have clang installed.

This is very weird. You should have <arpa/inet.h> installed.

Could you try installing it manually? You should be able to find all the necessary files here, in the folder include.

[vitalyster]

@Bowero For cross-compilation you need to have target system headers and libraries installed.

[Bowero]

@vitalyster, I understand that, but MacOS should have <arpa/inet.h> installed by default, since it is shipped with UNIX, not?

[vitalyster]

MacOS headers are not used in cross-compilation

[seven1240]

it auto downloaded a linux image, it should comes with the image. might be broken image? where I can find the image and delete it and retry? and in case the image is missing that, is there any doc on fix up the image?

Hi @seven1240 ,

can you confirm that the problem still exists on a fresh V (0.2.4)?

@ArtemkaKun , confirmed on 0.2.4.
