Title: Cross compile no go
Post by: Trenatos on June 27, 2017, 10:41:48 pm: I'm trying to cross compile from OSX to Linux.

I get the same error from inside Lazarus as when I do it from terminal with fink cross compile command.

Fatal: Cannot find system used by BrookRT of package BrookRT.

I tried creating a new application, just slapped a button on the form, and get a similar error different package.

Fatal: Cannot find system used by fcllaz of package FCL.

I've no clue what's wrong.

Should it be filled out when cross compiling?

Lazarus project settings may be empty, but your fpc.cfg may not be. Depending on how you install the cross compiler chain (that is, compiler + utils + packages), it might require changes (only when you install following the same structure as the host toolchain then it can be reused without changes). Look for -Fu lines in this file, make sure it matches your cross compiler packages path.
