Bug 416697 – cross-x86_64-pc-linux-gnu/binutils-2.22-r1 - configure:4060: i686-pc-linux-gnu-gcc -O2 -march=pentium4 ... // conftest.c:1:0: error: CPU you selected does not support x86-64 instruction set

• Status: RESOLVED OBSOLETE
• Product: Gentoo Linux

[Description Vu Tran Kien 2012-05-20 09:17:37 UTC]

I'm on a x86 machine and want to set up toolchain for amd64 with crossdev. So I called: crossdev -t x86_64-pc-linux-gnu, but the command failed with: C compiler cannot create executable.
Further investigation I figured out that crossdev is using the wrong abi for x86 machine: amd64, so I have to provide crossdev with: --abis i686
So if I was correct then please set the default abi for crossdev on x86 to i686 so it won't confuse newbies like me!
Thanks!!

Step to reproduce:
1. Sit on a  x86 machine
2. fireup: crossdev -t x86_64-pc-linux-gnu

1) Please attach to this bug report all files that the crossdev output mentions.

Now, should crossdev filter these out or should the toolchain ebuilds handle it themselves?

[Comment 8 SpanKY 2012-05-25 05:33:43 UTC]

i686 is not a valid ABI

the error you posted makes no sense.  what do you see if you run:
$ echo 'main(){}' > test.c
$ i686-pc-linux-gnu-gcc -O2 -march=pentium4 -mtune=pentium4  -Wl,-O1 \
  -Wl,--as-needed test.c

the two command exitted successfully.
file ./a.out gives: 
./a.out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped

cross-binutil environment file

May be the environment file will help
