Hello today I started to make a small app that acts as a clock for the PSP.
I ran into trouble when compiling as I get various errors where Cywin says that the header psprtc.h supplied with the pspsdk toolchain has syntax errors on almost every line. I also recieve an error due to the command
Code:
pspTime time

In the code below I have left out the initialisation of time. If anyone knows where Im going wrong whether it be coding or something else that works.

Thanks

Code:

          Thanks to www.ps2dev.org for the PSP SDK

Putting this line
#include <psprtc.h>
after this line
#include <pspkernel.h>
might help.

If you're compiling as .c then this
pspDebugScreenInit();
SetupCallbacks();
SceCtrlData pad;
pspTime time;
is all back to front. You can't have declarations inline with the code.
SceCtrlData pad;
pspTime time;
pspDebugScreenInit();
SetupCallbacks();

That will help a bit.

Jim

Ok thanks jim that got rid of that error. However I now get a
make: *** [Clock.elf] Error 1 message when compiling.

I remember I had this problem with another project which occured cause I missed out a required library on the makefile.
So far Ive got -lz but I dont know what other libs I need since just lz worked fine for similar coding,

yet this project includes the psprtc.h file so either Its not working or I need to state the lib for psprtc.h in the makefile.

But thanks jim.


EDIT: Ok i should have done this first but I did a google search there and found the lib i needed to add was -lpsprtc. And it works :)

For future reference, thats not the actual error message, just make informing you that it's quiting because something earlier failed.. It is completely unhelpful when trying to figure out what went wrong... You need to read up a bit higher to get the error message ;)
