[yocto] Yocto toolchain compilation Issues

[Rohit2 Jindal]

Hi ,

Actually I am trying to compile our own toolchain by applying our board specific patches to it in yocto . But getting error (attached error log) while running gcc-cross-initial for 4.6.3 toolchain .

I have removed some patches to make it compatible for my own required toolchain patch versions.


I have changed SRC_URI to download toolchain 4.6.3 tar and removed some patches applicable for 4.7.2 version of toolchain and added my own board specific
Toolchain patch. Its applying properly but at the compilation time gcc-cross-initial fails I am not able to understand the reason.

I have downloaded binutils 2.22 version for specific to our toolchain patch of binutils_222.patch and removed some patches compatible to 2.23.1 version of binutils .
Bitbake binutils-cross works fine removing some patches


But when I compile bitbake gcc-cross-initial do_compile failed .


1 I am not getting if I want to compile and install my own board specific toolchain I have to run only

Bitbake gcc-cross-initial
Bitbake gcc-runtime
Bitbake gcc-cross

2Please tell whether the above three bitbake commands all are mandatory to compile and install my specific toolchain or which command can be skipped.

3Please tell its dependency on newlib eglibc uclibc etc I am confused on all these things

4And please tell the mandatory changes to made for elf toolchain and linux toolchain respectively.

Thanks in advance!!


Regards,
Rohit Jindal
