SDLMAIN_LIBRARY not set in cmake about shadowgrounds HOT 6 CLOSED

Hi,

Looks like cmake was not able to find SDL core library.
From cmake's FindSDL.cmake:

Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
configuration and no SDL_LIBRARY, it means CMake did not find your SDL
library (SDL.dll, libsdl.so, SDL.framework, etc). Set
SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
value as appropriate. These values are used to generate the final
SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
does not get created.

Does 64-bit version of libSDL.so exist in default libraries location (/usr/lib/ or /usr/lib64/)? It should be installed by SDL.x86_64, I guess. Make sure it is SDL-1, but not SDL-2.
What cmake version do you use?

Details on libSDL.so:

[roland@farsight build]$ ls -l /usr/lib64/libSDL.so
lrwxrwxrwx. 1 root root 20 15 aoû  2014 /usr/lib64/libSDL.so -> libSDL-1.2.so.0.11.4

Version of CMake is 3.0.2

from shadowgrounds.

As I can see in cmake-3.5's FindSDL.cmake, there is hardcoded version of SDLmain library:

find_library(SDLMAIN_LIBRARY NAMES SDLmain SDLmain-1.1

I've got /usr/lib64/libSDLmain.a on my machine. Maybe there is a versioned libSDLmain on yours? If you are using SDL-1.2 this could be a problem.
Could you please run cmake with following additional arguments:
-DSDL_LIBRARY_TEMP=/usr/lib64/libSDL.so -DSDLMAIN_LIBRARY=PATH-TO-YOUR-SDLmain-LIBRARY

from shadowgrounds.

SDLmain was not installed on my system, after spending sometimes searching I find the package that contained it. I install it and cmake and make works as described in the wiki/build.

The package for fedora 21 is SDL-static.x86_64, maybe you could add this to the wiki.

I don't really get it on how to specify the location of the data files. The --data argument must be provided to cmake or make?

from shadowgrounds.

You can specify data location at run-time: shadowgrounds --data=/usr/share/games/shadowgrounds. You can also change the default path at compile-time: cmake -DSHADOWGROUNDS_DATA_PATH=/usr/share/games/shadowgrounds ... or via CMAKE_DATA_PATH -- it is a prefix of data directory: **/usr/share/games/**shadowgrounds .
Similarly for Survivor.

$ shadowgrounds --help

                                        Path to game-data directory

I'll update wiki in a few days.

Thanks. I can start shadowgrounds (I have not installed my copy of survivor yet), but it crashes at some point. I will open an issue for it.
