[svn] SDL.h not found, broken compile

#1 Post by greycat »

Code: Select all

==== Building physfs ====
Creating ../obj/Debug/physfs
physfs_byteorder.c
physfs.c
physfsrwops.c
In file included from ../src/physfs/physfsrwops.c:24:
../src/physfs/physfsrwops.h:30:17: error: SDL.h: No such file or directory

Code: Select all

#include "physfs.h"
#ifdef __APPLE__
#include <SDL/SDL.h>
#else
#include "SDL.h"
#endif
I am on Debian 6.0. Presumably __APPLE__ is not set. My SDL.h is in /usr/include/SDL/ so the __APPLE__ version is what should be used here. I'm not familiar with premake4, but shouldn't that be figuring out where the libraries and headers are, so we don't hard-code OS symbols in the code?

Ah, and if I fix that one by hand, then:

Code: Select all

==== Building TEngine ====
Creating ../obj/Debug/TEngine
main.c
In file included from ../src/display_sdl.h:24,
                 from ../src/display.h:23,

etc.
And:

../src/main.c:54: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘maincontext’
And if I fix all of those, then:

Code: Select all

../src/main.c:53: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token

src/main.c doesn't have any SDL #includes at all!

All I know is that latest svn requires sdl 1.2.

According to IRC, it requires 1.3. And if you go to the SDL home page you won't find it easily; it's hidden in the HG link. Also, it doesn't compile cleanly on Linux, or at least not the version I got moments ago....

Wow, this is ... huge. I got it working, with many steps involved, guided by the folks in the IRC channel. Let me attempt to write this all down while I can still remember some of it:
  • You need libsdl 1.3 which is NOT obtained by following the SDL 1.3 link on the SDL home page, but rather, is obtained from http://www.libsdl.org/hg.php using a Mercurial checkout. (sudo apt-get install mercurial to get the hg command.)
  • libsdl 1.3 from Hg would not build for me, on Linux. It blew up with fatal errors. I traced down the definitions and took a guess at a workaround: ./configure --disable-input-events -- this worked for me. You may not need this, if the bug is fixed in your own Hg checkout. Or you may not need it on non-Linux systems. (--enable-input-events is "use Linux 2.4 unified input interface" and toggles the bit of code that was blowing up.)
  • You do not need separate Hg versions of libsdl-ttf or libsdl-image. You do, however, need to tell premake4 where everything is. If you are building libsdl 1.3 in the default place, it installs into /usr/local/lib. The Lua files in t-engine expect it elsewhere, so they need to be edited:

    Note that the /usr/include/SDL/ path is where the Debian versions of libsdl-ttf and libsdl-image are; while /usr/local/include/SDL/ is where the Hg (1.3) version of libsdl itself is. Also note I had to tell it to link against png. This is apparently not needed on some other systems, but it was needed on mine.
  • After linking, it needs to be able to find libSDL-1.3.so.whatever, which in my case was accomplished by running ldconfig -v (as root). Alternatives include editing /etc/ld.so.conf first, or setting LD_LIBRARY_PATH at runtime, etc.

/edit: I realized I edited the wrong file xD. Still trying to get it to work.

I am trying to install SDL 1.3 and compile on ubuntu.
I installed SDL.
I tried to edit premake but some parts where missing from the premake file (no configuration linux)
I got the following errors:

Code: Select all

==== Building TEngine (debug) ====

To be honest I have no clue what I am doing.

This is what I did to my premake4 file:

The configuration "linux" part is in build/te4core.lua. You don't add it to ./premake4.lua.

I got this error too, using archlinux.

The problem is that we are using a different SDL version than DarkGod is. If you look at the source code for SDL_threads you can see that the SDL_CreateThread function has changed:

Code: Select all

DECLSPEC SDL_Thread *SDLCALL
SDL_CreateThread(int (SDLCALL * fn) (void *),
                 const char *name, void *data)
The important change is that the "name" argument has been inserted before the "data" one. This is fairly straight-forward to fix by finding all of the SDL_CreateThread calls in T-Engine4 and adding a dummy string name for the second argument. Here is my complete diff:

Which version of C lets you define a new variable in the middle of a function without starting a new block? Is that a C99 feature? I stopped using C professionally in between 89 and 99 so I don't know all the 99 stuff....

As of b34, DarkGod uses revision hg5580 from the SDL-1.3 mercurial repository. For the linux binary anyway.
