Various issues building

[tallero]

Hello, I'm having issues while building zlib, at linking stage.

The build script which causes error is this one.

Error is the following:

[ 97%] Linking C executable minigzip
/usr/bin/cmake -E cmake_link_script CMakeFiles/minigzip.dir/link.txt --verbose=1
/usr/bin/mips64r5900el-ps2-elf-gcc -I/usr/mips64r5900el-ps2-elf/include/pthread-embedded -I/usr/mips64r5900el-ps2-elf/include/newlib-nano -I/usr/mips64r5900el-ps2-elf/include -I/usr/include/ps2sdk -Wl,-L/usr/mips64r5900el-ps2-elf/lib/pthread-embedded -Wl,-L/usr/mips64r5900el-ps2-elf/lib -Wl,-Bstatic -lpthread -D_EE -O2 -G0 /usr/mips64r5900el-ps2-elf/lib/libc.a CMakeFiles/minigzip.dir/test/minigzip.o -o minigzip  libz.a

It goes on and on, apparently missing symbols from libc.

It seems mips64r5900el-ps2-elf-gcc is not able to produce a simple program without using the -r option.

If test.c is:

#include <stdio.h>
int main()
{
  int x = 5;
  printf("x = %d\n", x);
}

then mips64r5900el-ps2-elf-gcc -v test.c gives

Using built-in specs.

Including libc.a directly it's a lot of more undefined references.

It seems libzip requires attr.h

fatal error: sys/attr.h: No such file or directory
   47 | #include <sys/attr.h>
      |          ^~~~~~~~~~~~

[tallero]

Does really ode requires a build of libglvnd?

dreamgl.cpp:33:10: fatal error: GL/gl.h: No such file or directory
   33 | #include <GL/gl.h>
      |          ^~~~~~~~~

I don't know what you are doing, but I think you aren't putting proper flags when compiling.

The PS2 toolchain is kind of complex and there are some cycling dependencies, so you can't just link -lc and that's all. mips64r5900el-ps2-elf-gcc has some defaults libraries as you can see here: https://github.com/ps2dev/gcc/blob/ee-v11.3.0/gcc/config/mips/ps2sdk.h#L2-L11 These libraries are included by default, and you shouldn't include them again....

Then regarding your issues compiling zlib be sure that you don't compile also examples because ps2 binaries also require to have a custom linker file as you can see here: https://github.com/ps2dev/ps2sdk/blob/master/samples/Makefile.eeglobal_cpp_sample#L48

So not sure why it is not compiling for your arch distribution but something is wrong in your local I would bet.....

This doesn't seem to be an issue anymore. Reopen if this is not the case
