Cannot compile makeobj

[Vladki]

While working on smoke patches I found out that I cannot compile makeobj any more.
Last time I compiled (successfully) was on march 5th. (But I did not compile since then).
Simutrans itself can be compiled.

This seems to have caused the nightly build to fail, the nightly paksets are empty.

[jamespetts]

Thank you for the report: I believe that I have now fixed this.

[Vladki]

The error is still there. Now it says:

../descriptor/writer/bridge_writer.cc:153:92: error: 'pow' is not a member of 'std'

isntead of

../descriptor/writer/bridge_writer.cc:153:121: error: 'pow' was not declared in this scope

The rest of messages is the same

[jamespetts]

Thank you for the report: it seems as if this had been fixed for Windows but not Linux. I have now pushed a series of fixes which seems to work for both Windows and Linux, so this should be working in the nightly builds now.

Apologies for the trouble.
