libpspglue issues

[TommyBear]

Hi Guys,

Currently in ScummVM-PSP we've had to stub off these functions because of the following undefined symbols:

Now I know libpspglue implements these right? Has anyone successfully compiled a c++ file using libstdc++, libpspglue, libpsplibc and libc combined?

Here is the PSPSDK_LIBC_LIB var we are using:

PSPSDK_LIBC_LIB = -lm -lstdc++ -lpsplibc -lpspglue -lc

You're only to use either libpsplibc, or libc + libpspglue. Never both at the same time.

Well okay but libpsplibc does not implement:
__errorno
_impure_ptr
__assert

I'm using this:
-lm -lstdc++ -lpsplibc

Get this:

Unless I'm doing something completely whacky... This is why I included libc which implements these. This is using the latest released psptoolchain 625.

Well, you should really be using Newlib's libc. Your earlier output indicated you weren't using the latest toolchain, as read, write, sbrk, etc. should have an underscore in front of their names.

So grab the latest toolchain, and if you are manually specifying your libraries use -lc -lpspglue. Preserve the library order in build.mak.

[TommyBear]

Ok will do. Thanks

Tommy.

I'm basically in the same situation as TommyBear. After switching to newlib I got rid of some errors with _ctype_, _errno, etc, but now it's unable to find a number of functions (open, lseek, read, write, close, stat, fstat, and several others).

mrbrown indicated that if it had been compiled with the most recent toolchain that these functions should be prefixed with underscores, but I'm running today's 20050705 release and that doesn't seem to be the case. That's newer than the one available at the time of that post so things may have reverted or something but I had the same errors at one point with the 0625 version of the toolchain. Any suggestions?

For reference:
psp-gcc -O2 -G0 -fno-strength-reduce -Wall -D"USE_PSP" -L$(PSPSDK)/lib -lpspdebug -lstdc++ -lc -lpspglue -lpspkernel ...
