Cant compile - no png support

[Shaolin]

This is the error I get while compiling:

Code: Select all

checking for PNG support in SDL_image... no
configure: error: *** SDL_image has no PNG support! You need SDL_image with PNG support

The puzzling thing about this is, that i have both the normal sdl-image and the developement package installed.
So what is the problem?


EDIT: Probably important, I overlooked it before:

Code: Select all

configure: WARNING: SDL.h: proceeding with the preprocessor's result

I get those warnings for all sdl libs...

Maybe this patch helps you: https://gna.org/patch/?624

I have the same problem as well, except that I have already applied the most recent version of the patch already (1474). In addition to that, I get a bunch of errors saying how the headers of the SDL files are there, but can't be compiled. I also get something saying that g++ isn't being used, when I've installed it already. For reference, I've installed all the SDL files and their dev addons, along with g++, and the patch for configure.ac.

configure: error: *** SDL_image has no PNG support! You need SDL_image with PNG support

I'm curious as to why it says it's using the GNU compiler and not the GNU C++ compiler, as well. I would think that would solve compiling the header problems (and thus the PNG support problem as well).

Hello Forum,

I'd be very interested in an answer, too. Same problem here.

I even patched the configure.ac (hope I have done it right with patch -b configure.ac configure.ac.final.diff), but the same problem is still there. ./configure says, that the SDL_image library would not support png.

Any suggestions?

tarwin.

[greywolfexcel]

Thanks to grzywacz, my problem is solved. It appears that I had another version of g++ installed (g++ 4.1, to be exact), and it wasn't detected, so installed the normal g++, and it worked perfectly.

Sorry, I did not really understand, what you meant. I'd be very grateful if you could tell me (step by step), what is to be done...

Thank you!

tarwin.

P.S.: Isn't there any Ubuntu-Repository which hosts the newest Wesnoth version?

[greywolfexcel]

Heh, no problem. I'm using Kubuntu (the KDE version of Ubuntu), so some things might be different, like your package manager and stuff, but what I did was this:

1. Start up Adept Package Manager
2. Search for g++
3. Install the default g++ package (the plain "vanilla" version, NOT g++ 4.1 or anything like that).
4. Run ./configure again.

If it still doesn't work, then check to see if you see this line anywhere in the output:

Code: Select all

checking whether we are using the GNU C++ compiler... no 

If it says no, then you haven't installed the right package, or it isn't linked right or something similar. You should go onto the wesnoth irc channel; there should be a few linux wizards on there that can help you better than I can.

If it says yes, then it's another problem entirely. You should probably try checking the irc channel in that case.

As for a repository, there is one, but I think the newest version is 1.1.8, so unless you want to play that old version, keep at it!

[tarwin]

Dear greywolfexcel!

Wonderful, this is it! You helped me a lot and I think it worked out now (the game is acutally running). I use the normal Ubuntu distribution and yes, after installing the right compiler everything turned out fine.

Thanks a lot!

Best wishes!

tarwin. <-- still wondering, which compiler Ubuntu installed on default

[greywolfexcel]

Good to hear it's working for you! But please, thank grzywacz! He's the real hero here.

If none of the above works to get rid of that SDL_Image/png error?

Run ./autogen.sh

[PhotonX]

Hello,

I've the same problem:

Code: Select all

checking for PNG support in SDL_image... no
configure: error: *** Either your test image has vanished, or SDL_image has no PNG support!

I've g++ installed (both the normal one and the 4.1 one) and I've run ./autogen.sh. The Wesnoth version is the latest SVN (trunk) and I'm running Ubuntu Gutsy. All dependencies (and also all the sdl libs) seem to be installed but I still get this error. Any ideas?

[SkeletonCrew]

Try 'apt-get build-dep wesnoth' to make sure all dependencies are properly installed.

[PhotonX]

Thanks for the hint but unfortunately it didn't work. There were really packages missing (cdbs debhelper html2text intltool-debian libfribidi-dev po-debconf) but I still get the same error. I think there is something wrong with sdl-image. Which version do I need for compiling? I've libsdl-image1.2 and libsdl-image1.2-dev installed, both are version 1.2.5-3 (from the Gutsy repos).

[SkeletonCrew]

Those missing packages shouldn't cause this problem, not even sure whether they are really needed.

I also use sdl image 1.2.5 (Debian Etch) and have no problems...
Do you have the file 'images/buttons/button-pressed.png' on your system?
If not this error also occurs, since that's the test image.

[PhotonX]

Hmm, I've the file /home/photon/svn/wesnoth/images/buttons/buttons-pressed.png so if this is the needed file: Yes, it's here. But if it isn't, there isn't such a file elsewhere on the system, only where the Wesnoth files are.
