Can't compile the Meaty Skeleton tutorial (Cygwin)

[heat]

I am trying to compile the Meaty Skeleton on my cross-compiler.It is failing to compile because it can't find the include files.
I am using a gcc 4.9.2 with a binutils 2.25.0 ,for the target i686-elf.I have downloaded the Meaty Skeleton from the Git repository.
I am compiling this in Windows 8.1.

I suspect that the sysroot option on my compiler is not working properly.

Please help me as I do not know what to do to solve this.

[Techel]

Seems like the include paths are not set properly.

[heat]

Shouldn't the --sysroot and -isystem options work as include paths?

[sortie]

Do you have any unexpected spaces or special characters in the path, perhaps?

[heat]

No.I even copied the whole folder to C:/, ran the build script and it still gave me the error.

[sortie]

Try pass --verbose to the compiler. Also please use code tags for your logs. Also, unless your identity actually needs to be hidden, please don't censor the output, I can help much better if I get the true data and I know it is the case.

Note: Meaty Skeleton was not designed with cygwin in mind. Any other cygwin users, please try and see if it works for you? But it's not designed to work on Windows, but I did not expect issues like this.

Here is the log with the --verbose option.And thanks for the tips.I am new to the osdev forums

I think your include paths were not set properly when you ran the compiler.
I recommend that you try adding something like '-I include/' based on where your "kernel" header directory (where "tty.h" is inside) is located.

stdio/putchar.c:4:24: fatal error: kernel/tty.h: No such file or directory
#include <kernel/tty.h>
^
compilation terminated.
Makefile:72: recipe for target 'stdio/putchar.libk.o' failed
make: *** [stdio/putchar.libk.o] Error 1

When you use the "<>" brackets in the '#include' directive, gcc looks through the include paths, and since it is unable to find 'kernel/tty.h' in the include paths, you should add it.

hope that's helpful.

Thanks! It worked. But i think that the problem was in here:

Code: Select all

ignoring nonexistent directory"c:/Users/Pedro/SpartanOS/sysrootC:/MinGW/msys/1.0/include"

The second path is for some reason mixed with the first path.

[sortie]

I'm more worried about:

Code: Select all

ignoring nonexistent directory "/cygdrive/c/Users/Pedro/SpartanOS/sysroot/usr/include"

But the output above claims it does exist. I think the problem is that your GCC doesn't like /cygdrive paths somehow.

It also tried to look for C:/MinGW/msys/1.0/include inside the sysroot, which doesn't make sense. Perhaps your cross-compiler somehow targets cygwin partially? Or perhaps that path came from the environment (see C_INCLUDE_PATH and such) in a weird way?
