Help sought with nettool compile issue

[jamespetts]

I am in the process of trying, eventually, to release the next version of Simutrans-Experimental (10.12), but I have hit upon a bizarre problem compiling Nettool - I am getting the following compile errors:

The float32e8_t is a special class for cross-platform network synchronised capable floating point values written by Bernd Gabriel for the physics calculations. I cannot find any references to it in the nettool files, which I think are more or less unchanged from the Standard versions. If there is no reference to any float32e_8_t object in any of the nettool .cc files, I cannot understand how the LNK2001 error is thrown in MSVC. Any thoughts on the topic would be much appreciated.

Any thoughts, anyone...?

network.cc includes network_cmd_ingame.h, which includes simworld.h, which includes simunits.h, which has float-arithmetic with constants, which the linker cannot resolve.

hope this helps.

That does help - thatnk you very much! Now fixed.
