Problems compiling MIPS cross compiler

[rosco_pc]

As stated here Re: Ingenic Jz4740/Jz4732 players I have problems compiling a MIPS cross compiler. I'm using the rockboxdev.sh script to do this under Ubuntu 8.04 (Hardy).

I get an " 'O_RDONLY' undeclared " error, which would suggest that I do not have a proper build environment set-up (missing linux headers), but I do have both build-essential, libc6-dev and the linux headers instaled. And compiling another cross compiler (ARM) works without problems.

What I tried sofar:
 

• Use --disable-libssp
• Use --disable-libmudflap --disable-libssp
• Use --without-headers
• Use --without-headers -- disable-libssp

None helps, any other idea's?

PS I got a working copy via mcuelenaere, but I'm just curious as to why it does not compile

Hi, I tried compiling the mips crosscompiler on my hardy box and got the exact same error in libssp but adding "--disable-libssp" in rockboxdev.sh (end of line 253) made gcc build fine.
Where did you put your command line switches?

I guess my latest commit to rockboxdev.sh broke the MIPS cross compiler, but I wanted it to be the same version as the one Ingenic provides; but I can't see why some other version numbers break building gcc..

(BTW the version Ingenic provides has some patches applied)

It's an oldish gcc bug that exist in 4.1 and later AFAIR, just build with --disable-libssp, we don't use it anyway. It might be nice to make rckboxdev.sh do this automatically for >= 4.1 builds. This does affect gcc for other targets too but that doesn't matter much since rockboxdev.sh is for building recomended versions.

yep, got it to compile now as well with --disable-libssp. Not sure how I missed it, but the editor I have been using (nano) wrapped the  line

Use a real editor

[cool_walking_]

 

Turn wrapping off.

[mcuelenaere]

Compiling MIPS should now be fixed in SVN..

[rosco_pc]

Turn wrapping off.

This is using the defaults from Ubuntu, did not think they had wrapping on (and I certainly did not turn it on). Ah well

Use a real editor

such as VI or EMACS?
