[SOLVED]Problems with i686-elf-gcc

Posted: Mon Jan 19, 2015 5:05 pm
by bashcommando
Hello again, I am having problems with my cross-compiled version of gcc. Just like the tutorial I cross-compiled gcc and binutils(and had to build some packages from the source). Whenever I try to compile something with it it says it that ld can not find certain files and the build fails. Any help? I am currently using GNU/Linux(Pinguy 14.04) and I don't know what to do. :D Please help?

Please read your post. Do you really think that there is enough information there to guarantee that someone can provide constructive help ?

Hint: The answer is not "Yes".

I don't need the hint, what else can I provide? Oh wait, I am using gcc 4.9.2, binutils 2.25 and here is a error log(I got a different error this time):

cross-compiler
Why is the only instance of "elf" in the thread title, and everything else "linux-gnu"? There's no cross-compiler involved anywhere.

Minimalism is all very well in its place, but you are still not providing enough information. At the least we need to know the contents of your $PATH variable and the command line that you are using to compile your program. The fact that it is trying to link against your normal library files rather than the cross-compiler ones indicates some fairly fundamental mistake.

Also note that whatever you are trying to compile does not contain a "main" function which C assumes exists (crt1.o will call it) unless you tell it otherwise. What are you trying to compile? A kernel, a user program, a library, or what?

Thanks for replying, no I didn't compile it with -ffreestanding and yes I am using a cross-compiler. It is located in ~/opt/cross/bin/i686-elf-gcc.

A program to test if it would work, my path was just like it said in the tutorial.

Code: Select all

void main() {
    asm volatile("nop");
}
And sorry again for being a noob. OS development is confusing, I will try to read a lot more of the wiki and search ddg before posting my next question.

So I compiled with -ffreestanding and it gave me the error I had before:

Code: Select all

ffreestanding

What noobish mistake did I do this time?
Edit: I figured it out. I don't have libgcc for i686-elf.

You did not follow gcc build recomendations.

Try to exit gcc directory and create another directory for call the make.

Try to exit gcc directory and create another directory for call the make.

More instructions: http://wiki.osdev.org/GCC_Cross-Compiler
So I have to re-download gcc again? I already followed the instructions. I'll try again.

No, you haven't. re-extract GCC files and call make out of GCC dir

Example:

cd /home/user
extract command
mkdir build_dir
cd build_dir

Inside of build dir, you call the make

../gccdir/make

No, you don't do it like this, because it doesn't matter from where you 'make' the project, but from/to where you 'configure'd it.
You call the binutils/gcc/whatever configure scripts from within the build dir and then call make within the build dir.

Code: Select all

mkdir gcc-4.x-build
cd gcc-4.x-build
../gcc-4.x/configure yourflags
make
make install

I followed the tutorial as accurate as possible and downgraded to gcc 4.8.3 and binutils 2.24. I got this:

Code: Select all

/home/bashcommando/opt/cross/lib/gcc/i686-elf/4.8.3/../../../../i686-elf/bin/ld: cannot find crt0.o: No such file or directory
/home/bashcommando/opt/cross/lib/gcc/i686-elf/4.8.3/../../../../i686-elf/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
What else am I doing wrong?
