Hey, have you tried these binaries (I haven't): http://wildfiregames.com/forum/index.php?showtopic=16680&p=264680 I am trying to build the game under Ubuntu and getting the exact same errors (using those instructions: http://trac.wildfiregames.com/wiki/BuildInstructions). 'binaries/system/libCollada.so' does not exist. Whe re-running 'update-workspaces.sh, the suspicious messages are: -- Looking for DirectX - not found -- Looking for TIFF - not found I solved the second issue by installing some `libtiff` packages. I wonder if this is a mistake on my part or is a missed package in the isntructions. But after rebuilding, there is still no libColldata: vorac@laptop:~/projects/0ad/binaries/system$ ls | grep libColldata return nothing. ------------------------------ EDIT: So, here's the happy ending to my story. I called clean-workspace, followed by update-workspace and now all tests are passing.
