cross-compiling support

[Henrique Ferreiro]

Hi, when using goma there was support for cross-compiling for Windows on a Linux host with goma. It appears that this functionality was lost with the migration to reclient. Will this setup be supported at some point?

Hi Henrique,

Could you clarify which of the two things you are trying to do?

1) You run autoninja on a Windows PC and want to build a Windows Chromium binary, but use cross-compilation on Linux workers for remote execution?

2) You run autoninja on a Linux PC and want to build a Windows Chromium binary, and use remote execution (not sure if you're looking to use Windows or Linux workers)?

Cheers,

Philipp

It's 2. This would just work on goma: https://chromium.googlesource.com/chromium/src/+/master/docs/win_cross.md#goma. I assume only Linux workers would be involved, but that all was transparent to the user.

Thank you for the information! I will find out why this no longer works and how we can fix it.

By the way, what is the error you get if you try to do the cross-compile build using reclient?

[Henrique Ferreiro]

I'm sorry, I had a misconfiguration regarding the Windows SDK that I misinterpreted as lack of support from reclient. Everything is working as expected :-)
