gcc-config: error: could not run/locate 'i686-pc-linux-gnu-gcc'

[klkblake]

I'm trying to update dev-libs/nss so I can update firefox, however it fails with a message saying that it cannot find "i686-pc-linux-gnu-gcc". I do not in fact have such a file on my system, except for /usr/bin/usr/bin/i686-pc-linux-gnu-gcc which is the gcc-config wrapper. Attempting to run that produces the final line of the log. I am particularly confused by the "broken config file" error, as I haven't touched that file to my knowledge. I would guess that I messed up something during the transition to ARCH_X86? Any help would be very much appreciated.

I don't know what You wanna make....

 

But: is correct "i686-pc-linux-gnu-gcc" ?

May be corect "i686-pc-linux-gnu" ?

 

Since You are on a 64 bit system, is not necessary to make:

 

# linux32 

 

before the compilation for 32 bits software then change the "CHOST=" ? but to change chost may be dangerous.....

 

(and excuse my ignorance ..... 

[klkblake]

I think the "-gcc" part is correct. If I understand what is going on correctly, their should be a directory of files called i686-pc-linux-gnu-{gcc,gas,ar,ld,etc} created by a multilib install of gcc, and it is complaining that it cannot find the gcc one. linux32 and CHOST changes should not be necessary; the multilib infrastructure should be responsible for doing that stuff as necessary, and I can confirm that at the point where gcc is being invoked CHOST=i686-pc-linux-gnu.

[Oleg Vinichenko]

what is ARCH_x86 transition mentioned above?

[klkblake]

Oh, that's a typo, sorry. I meant the transition from emul-linux-x86-* to ABI_X86="64 32".

[klkblake]

Problem solved!

qfile -o /usr/bin/i686-pc-linux-gnu-*

reported that several gcc-related files there were orphaned. I deleted them, and everything Just Worked. I *think* this is because I had the new toolchain unmasked when people where doing the experimental multilib wrappers or something.
