I decided to try using the cross-sdk method but i keep getting this error messege.

checking for SDL - version >= 1.0.1... no
*** Could not run SDL test program, checking why...
*** The test program compiled, but did not run. This usually means
*** that the run-time linker is not finding SDL or finding the wrong
*** version of SDL. If it is not finding SDL, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location  Also, make sure you have run ldconfig if that
*** is required on your system
***
*** If you have an old version installed, it is best to remove it, although
*** you may also be able to get things to work by modifying LD_LIBRARY_PATH
configure: error: *** SDL version 1.0.1 not found!

Any ideas. The host system is a 1.2 ghz pentium running gentoo.

it says it all

The program compiled but did not run.
because you are crosscompiling, the test program is compiled for arm, and did not run because it runs it on x86.

not all configure script are made or tested to behave correctly in the case of cross-compilation.

In this case I usually hack the configure script to bypass the test ( ie making it to return true all the time, if I know the answer)

The newvox program had a --disable-sdltest function so i used that and it passed the ./configure. Now when i "make" i get this

It compiles fine but wont execute on the zaurus i get an "cannot execute this binary" the permissions are set fine on it.

So far this whole experince has been extremly educational. I want to thank you pgas for all your help and patients.

thanks.

It seems that your compilation does not use the cross compiler.

did you run configure with  something like
Code: [Select]
LDFLAGS="-Wl,-rpath-link,/opt/arm/3.3.2/armv5tel-cacko-linux/X11R6/lib" ./configure --host=armv5tel-cacko-linux --build=i686-linux --x-includes=/opt/arm/3.3.2/armv5tel-cacko-linux/X11R6/include --x-libraries=/opt/arm/3.3.2/armv5tel-cacko-linux/X11R6/lib --disable-debug --prefix=/usr/local  
 replacing the path used by the one of your cross sdk?
 and replacing --host=armv5tel-cacko-linux by host=arm-cacko-linux (note that besides the path /opt/arm... in your sdk the X11R6/include might be just include)

is there no arm-cacko-linux-gcc in /opt/cross/arm/3.3.6-sa1100-softvfp/bin/ ?

do you run /opt/cross/arm/3.3.6-sa1100-softvfp/runsdk.sh before compiling?

I did run runsdk.sh before hand. I dont have arm-cacko-linux-gcc but i do have g++, gcc, c++. Should i make a symbolic ling from gcc to arm-cacko-linux-gcc?

Scratch that i was in /opt/cross/a/opt/cross/arm/3.3.6-sa1100-softvfp/arm-cacko-linux-gnu/bin/ instead of
 /opt/cross/arm/3.3.6-sa1100-softvfp/bin. SO yeah its there.

hmm, I guess I will have to download the cross sdk and try out to see If I can find what's wrong...

is it arm-cacko-linux-gnu or arm-cacko-linux ?

maybe you should pass --host=arm-cacko-linux-gnu ?

That was the problem. Everything works great now. Now its time to try and figure out the kernel stuff.
