emerge gcc 4.52 results in downgrading glibc [Solved]

[k4ph]

Hi all,

I'm trying to emerge gcc 4.5.2, but all that happens is, that every time, emerge tries to downgrade glibc to glibc-2.9_p20081201-r3:

I have done

Code: Select all

echo ">sys-libs/glibc-2.11.2" >> /etc/portage/package.mask

but emerge just ignores this masking, so I don't get a clue, how to solve my problem. Every forum entry I found within sabayon/gentoo forums told me to mask it.

Is there any other step, I can/must make?

Best regards,

Karl

Did you look at /etc/portage/package.mask ? Should be an entry already there to edit, you probably have a couple entries now.

Thanks, wolfden, the hint was very good!
Indeed I found a second entry of glibc. After setting it back to only one glibc-entry (>sys-libs/glibc-2.11.2) - it only wanted to downgrade me to glibc 2.10.x.
I then set /etc/portage/package.mask to sys-libs/glibc - and that works, I'm just compiling version 4.52 of gcc. But I must again read the complete portage guide. I still don't understand, while it tried downgrading when setting the mask to >2.11.2 and doesn't try when setting the mask to no version.

Thanks again for helping,

Karl

>>> Installing (4 of 4) sys-devel/gcc-4.5.2

^.^ .... that was the message, I wanted to see.
GNU CC 4.5.2 is installed up and running - and works perfectly for me.

Thanks a lot again!
