Description Stefan Salewski 2006-11-08 07:54:19 UTC

I have done a clean 2006.1 (AMD64) install some weeks ago, using Kernel 2.6.18-r1.
emerge --update --deep --newuse world 
failed when emerging gcc4.1 with message like
"checking whether the c compiler works"
"configure: error:  cannot run C compiled programs."

After recompiling kernel with option
CONFIG_IA32_EMULATION=y
emerging gcc4.1 works. (of couse after reboot into new kernel)

Can you confirm that we have to enable IA_32_EMULATION to emerge gcc (and glibc)? (Emerging other software works fine without IA_32_EMULATION).

Best regards

Stefan Salewski

Yes. 

In future, please use #gentoo-amd64 on freenode, forums.gentoo.org or appropriate mailing list for support questions. Bugzilla is not a support forum.

So I call this a serious bug (at least in documentation)!
I think only very few people know that we have to enable
CONFIG_IA32_EMULATION=y
to emerge gcc or glibc. (I found some reports about this kind of emerge problem, but only one hint for enabling IA32_EMULATION. And no explanation why we need it.)
