 |
|
I tried to use crossdev to build a toolchain for mips.
I specified gcc version, uclibc version, and kernel header version.
But crossdev always ignores my kernel header version.
| Code: |
$ crossdev -pv -t mipsel-pc-linux-uclibc --b 2.16.1 --g 3.4.5 --k 2.6.11 --l 0.9.28

mips-heaaders are hard-masked, something like
| Code: | echo "cross-mipsel-unknown-linux-uclibc/mips-headers * ~* -*" >> /etc/portage/package.keywords
]echo ">cross-mipsel-unknown-linux-uclibc/mips-headers-2.6" >> /etc/portage/package.unmask |
may be required, though I thought crossdev inserted some of that for you. I think crossdev needs you to
specify a full build (i.e. 2.6.11) but I couldn't get it to work. In my case I inserted
| Code: | | echo "<cross-mipsel-unknown-linux-uclibc/mips-headers-2.5" >> /etc/portage/package.unmask |
to get crossdev to emerge the latest 2.4.xx kernel. I don't know if this is specific to mips, but with arm arch I was
able to specify a kernel version without incident, whereas for mips it iseemed like it gnored my settings.
You might be able to force >=2.6.11 in a similar way if the unmask doesn't help.

Thanks.
I noticed that crossdev didn't modify /etc/portage/package.unmask automatically.
So I put my desired package into it.
| Code: | =cross-mipsel-pc-linux-uclibc/mips-headers-2.6.11-r1
|
Now it works.  |

Cool! I'm still curious as to why mips-headers are hard masked and probably would be scared off by the answer 
Generally things aren't hard-masked without good reason.
Out of curiousity, what platform are you building for?
Btw, if you weren't aware, a nice feature of the 0.28 uClibc ebuild is the addition of the "savedconfig" USE flag, before which we had to settle for either a generic unoptimized toolchain or manual installs of uClibc. It's a *very* nice feature in fact, for making crossdev automation a lot more feasible for real applications. Just noticed savedconfig wasn't in your crossdev output, apologies if you already knew about the "savedconfig" option.
