Compile warnings /lib/netplay.c

[R3dP!pe]

I want to modify the intelligence menu a bit, so I downloaded and compiled the svn trunk. I'm using Ubuntu 7.10 and your description in the Wiki worked fine (except that the required flex version is newer than the Ubuntu package).

But make failed because of 3 warnings in /lib/netplay.c. In lines 1620, 1251 and 1530 the function SDLNet_TCP_Send() is given a const char*, but the function seems to remove the const qualifier:
msgid "passing argument %d of %qE discards qualifiers from pointer target type"

When I add a typecast to char* (SDLNet_TCP_Send(tcp_socket, (char*)"list", 5); ) it compiles.

Hooray for const correctness!  ::)

[Per]

What version of gcc are you using?

Also interesting: Which version of SDL_net is that?

[R3dP!pe]

libsdl1.2debian is version 1.2.11-9ubuntu2, also libsdl1.2-dev is 1.2.11-9ubuntu2.

gcc is version: gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

These are the standard 7.10 distribution packages.

Warnings are treated as errors. Isn't this a setting in the make file?

[Per]

You should check your version of SDL_net. Here it has a const pointer in its second argument, which should not give these warnings.

Actually it's an option you can give to the configure script. Try running configure with --enable-debug=relaxed to allow warzone to compile with warnings.
