Errors compiling SDL_image library...

[statikeffeck]

OK I would like to compile the "Vectoroids" game found in pspware of SVN.

So I am getting all of the required libraries from SVN (in order)
zlib - maked & installed
libpng - maked & installed
jpeg - maked & installed
SDL - maked & installed
SDL_image - got errors, explained below
SDL_mixer - didn't try yet

for SDL_image, I ran ./autogen.sh and then did:

Code: Select all

LDFLAGS="-L`psp-config --pspsdk-path`/lib -lc -lpspuser" \
     ./configure --host psp --with-sdl-prefix=`psp-config --psp-prefix` \
     --prefix=`psp-config --psp-prefix`

it complained with:

Code: Select all

...
checking for PSPSDK... /usr/local/pspdev/psp/sdk
checking for sdl-config... /usr/local/pspdev/psp/bin/sdl-config
checking for SDL - version >= 1.2.4... cross compiling; assumed OK...
yes
checking for jpeg_CreateDecompress in -ljpeg... no
configure: WARNING:
*** Unable to find JPEG library (http://www.ijg.org/)

configure: WARNING: JPG image loading disabled
...
similar errors for PNG and zlib libraries

I'm sure there's a way to tell the ./configure where the image libraries are. I did a search and found that libjpeg.a exists 3 times:
in C:/cygwin/lib
C:/cygwin/home/StatiK/jpeg
C:/cygwin/usr/local/pspdev/psp/lib

Thanks people.

You should have a file in the SDL_image directory called config.log that gives details on why it failed to find libjpeg (near the bottom). Could you post the relevant portions of that log here?

ok here is the relevant info from config.log:

ah... so we see pspSdkInstallNoDeviceCheckPatch has something to do with the problem.

[rinco]

you will need to update your SDL from SVN... sdl-config now spits out -lpspsdk (has pspSdkInstallNoDeviceCheckPatch).

[statikeffeck]

Thank you, this solved the issue.

Moral of the story: Update all your packages with SVN.

[rinco]

was my bad... but yes, always update from svn.
