but when it comes to building SDL_image, it dosnt seem to want to find the jpeg

there is someting amiss with the configure script.

IIRC, Cygwin’s packages such as libjpeg, libpng,… have a binary version
containing just the dll’s (that is what you seem to have installed so far)
and a development package including the header files and the necessary files
to perform the linking stage. Look for them in the “development” category of
Cygwin.

Can i build SDL audio with libasound(alsa-lib) static??
Thanks…
Hello !
IIRC, Cygwin’s packages such as libjpeg, libpng,… have a binary version
containing just the dll’s (that is what you seem to have installed so far)
and a development package including the header files and the necessary
files
to perform the linking stage. Look for them in the “development” category
of
Cygwin.
No this is a general problem with SDL_image and JPEG.
Under cygwin i have all needed JPEG libs and includes installed
from the GnuWin32 Site ( http://gnuwin32.sf.net )
and i get this error.
Configure detects a working jpeg library
but when it comes to printing out the dynamic names for example jpeg.dll
libpngxyxy.dll and so on, it only prints the libpng…dll and the
libtiff…dll.
The exact same thing is happening under Linux ( Slackware 11 ).
The same problem there.

Does it happen if you grab the latest code from SVN?

mine was from SVN ( cygwin )
i dont seem to be able to get a linux to install on this mcahine without it
freaking out and switching off, sorry i tell everyone that. winds me up
cronic.
1024x768 windows xp home as a development environment, great, just freaking
great. right you probably already knew i used svn for cygwin so i’m
spamming up
the lists with my random keeerap again. freaking winxp home… freaking
playmobile flatscreen monitor… blah.
oh yes, i did still have to do the put the .h files in the same directory type
make and hope for the best thing to get it to find png tiff and zlib…
even tho
they are in /usr/include… still dont know if it’s my fault they didnt get
found…

autogen spits out some errors… sunno if these are significant…

and i still had to put jpeglib.h png tiff z etc in the SDL_image dirctory to
get it to behave… even tho they are in /usr/include - is this something i am
doing wrong? shouldnt the configure / sdl_image find this?
i am about as good with makefiles / autoconf as i am at writing sane
understandable posts to this list
and this pops up at the end

Hello !
SDL_image shows “dynamic linking jpeg.dll …” now.
The only thing i have to do to get it compile
is to do export CFLAGS=-I/usr/local/include
then call configure.
jpeg is installed the same as libpng in /usr/local
on my system.
