Setting Up Dev-cpp

[MattPurland]

Hi, I've followed the tutorial on the wiki (http://wiki.gp2x.org/wiki/Using_Devcpp) for setting up dev-cpp with the devkitgp2x but I get the following error:

File format not recognized
G:\My Documents\Work\PNGTest\Makefile.win [Build Error] [PNGTest.gpe] Error 1

I'm a bit of a n00b at this, but any idea's why it would give this error? I've double checked the setup many times and I can't see where I've gone wrong

Cheers!

Any ideas? I've replaced the devkitGP2X with a newer one (HW SDL, etc) and I get the following:

no input files
G:\My Documents\Work\PNGTest\Makefile.win [Build Error] [main.o] Error 1

I don't undsertand why it can't find main.cpp

Someone had a similar problem a while ago on this forum. Have a little dig in the old posts and see if you can find it. I use codeblocks myself so I can't help. Sorry.

I've given up on dev-cpp and gone for codeblocks. Better results but I get this when compiling:

Any ideas?

Yep, you need to link with libjpeg and libpng (if I'm not mistaken)

(Add -ljpeg and -lpng to the link part of your makefile)

 

[MattPurland]

I'm not using any jpeg's but ok

Edit:
Now I get this error, any ideas?

Can I see your linker line? eg
-static -lSDL etc

Also, did you manage to get the example to compile from the Wiki tutorial?

 

[Blah]

Add -lz

Remember that SDL_Image depends on libjpeg and libpng. And libpng depends on zlib.

 

[MattPurland]

This is my linker line:

-static -lSDL_ttf -lSDL_image -lSDL -lfreetype -lpthread -ljpeg -lpng

I'll try the test program now

ooh it compiled, thanks Mr. Blah!

 

[yaustar]

Blah was right, you are missing -lz. Glad you got things going now
