Broken Build on Mac OS X

Broken Build on Mac OS X

[Andre Smith]

I would like to report a broken build on Mac OS X using cross  
compiler powerpc-elf version 4.0.2 using binutils 2.16.1 and newlib  
1.13.0. I get the following error message after running configure -- 
host=powerpc-elf followed by a make:

grub2/commands/help.c: In function 'grub_cmd_help':
grub2/commands/help.c:42: error: nested functions are not supported  
on MacOSX
grub2/commands/help.c:65: error: nested functions are not supported  
on MacOSX
make: *** [grub_emu-commands_help.o] Error 1
console:~/opensource/bootcode/source asmith$


Fair warning, I am new to the list and GRUB2 source code. I wanted to  
report this to the list first, to see if anyone was aware and/or  
working on this issue. I am interested in getting GRUB2 to work on  
the Mac in an effort to support porting efforts of OpenSolaris on  
Apple hardware. Any help on this is greatly appreciated.

Thanks,
Andre

You omitted the full gcc invocation, but I suspect that you are not 
actually using your powerpc-elf cross-compiler here. Could you verify 
that?

Re: Broken Build on Mac OS X

[andre-smith]

My apologies, if I'm not doing this right. I set the path from my cross compiler; it points to powerpc-elf-gcc, powerpc-elf-ld, powerpc-elf-*. If I don't do this, configure actually fails since using the darwin version of these compiler tools produce binaries that can not link at absolute address 2000.

Andre

P.S. I can certainly post the complete results from the make; as soon as I get home.

Here is the full build process; it includes the setting of the PATH  
to the cross compiler tools, the configure statement, and finally the  
make:

After searching a bit with google, I found this thread:

http://lists.apple.com/archives/Xcode-users/2005/Nov/msg00267.html

It seems that the apple version of gcc (?) had nested functions
disabled because of the executable stack.  It seems to me that this
was done by the apple developers and not by the gcc developers.

The reason they did this was because they was to disable executable
stacks.  And the way they did seems quite awkward to me.  Instead of
disabling it by default they just disabled it completely.  You might
have to consider building gcc yourself or using an older version.

Re: Broken Build on Mac OS X

[Andre Smith]

Thank you for that information Marco. I will get on the gcc mailing  
list to see if there is a known process for re-enabling nested  
functions. I swear that really bites, and I wish Apple used some sort  
of flag to disable that feature. If I find out something positive,  
I'll report back to GRUB2 list.

Re: Broken Build on Mac OS X

[Andrei Warkentin]

Hello,

I would suggest building a bootstrap gcc powerpc crosscompiler and  
binutils, where the the host is your OS X system and the target is  
powerpc-linux. This will allow you to build PowerPC ELF objects,  
which you can then boot with OF. It is my understanding that the  
GRUB2 PowerPC build pretty much assumes ELF. OpenFirmware is now  
capable of running Mach-O executables, but I have never tried that.

Here is the configure
command I passed to configure GCC4 prior to compiling -

../gcc-4.0.2/configure --target=powerpc-linux
--prefix=/Users/andreywarkentin/crossdev/powerpc-linux --disable- 
shared --disable-threads
--enable-languages=c,c++ --with-newlib

[Andre Smith]

Thanks Much! I will build that tool chain and rebuild GRUB2.

Re: Broken Build on Mac OS X

[Andrei Warkentin]

Hello,

I should add a 'caveat emptor'. I've never built GRUB2 on OS X  
before, and, although I do not anticipate issues with the method I  
mentioned in my previous email, I am not guaranteeing success either.  
I've built my kernel both on Linux and OS X this way though, and I  
had no issues. My understanding is that you will have to somehow  
convince the GRUB2 build to use your gcc versus the system one.

Have a good day.
