Problem Setting Up libpng and zlib

[hyakuhei]

Hi guys,

Right, im setting up an environment to build a few test apps on the PSP, I should point out that im running gentoo not cygwin.

Ok, I have downloaded the trunk svn psp friendly libs, and here is a quick run down of what I have done:

Code: Select all

cd libpng
make
make install
//This installs correctly to the pspsdk include directory
cd ..

Code: Select all

cd zlib
make
make install prefix=/usr/local/pspdev/psp/sdk
//This seems to work and install into the right place
cd ..

Now the problem I have is that when I try to compile my very simple graphics program I get the following compiler library error:

Code: Select all

operative@serenity ~/Development/PSP/helloworld2 $ make clean
rm -f hello.elf  main.o graphics.o framebuffer.o PARAM.SFO EBOOT.PBP EBOOT.PBP
operative@serenity ~/Development/PSP/helloworld2 $ make

collect2: ld returned 1 exit status
make: *** [hello.elf] Error 1

As you can see, this sucks, any advice would be welcome

Thanks

Your compile of zlib seems to have produced an invalid lib, try to recompile and reinstall.
