 Posted: Wed Jun 14, 2006 9:19 pm Post subject: eselect compiler won't select gcc-4.1.1 |
 |
|
Hi,
I've upgraded gcc-config to 2.0.0-rc1. It tells me to use eselect:
| Code: | # gcc-config
Usage: gcc-config [<options>]
WARNING: gcc-config is deprecated and is just a frontend to the compiler
eselect module. In the future, gcc-config will be removed
from portage. Please see 'eselect compiler help'
|
So I did:
| Code: | # eselect compiler list
Available compilers for CTARGET i686-pc-linux-gnu
[1] i686-pc-linux-gnu-4.1.1/vanilla
Activated profiles:
i686-pc-linux-gnu i686-pc-linux-gnu-4.1.1/vanilla
# eselect compiler set 1
Successfully set compiler for i686-pc-linux-gnu to i686-pc-linux-gnu-4.1.1/vanilla.
# eselect compiler list
Available compilers for CTARGET i686-pc-linux-gnu
[1] i686-pc-linux-gnu-4.1.1/vanilla
Activated profiles:
i686-pc-linux-gnu i686-pc-linux-gnu-4.1.1/vanilla
# eselect compiler show
(none)
|
'gcc' doesn't work but 'i686-pc-linux-gcc' does:
| Code: | $gcc
gcc-config error: gcc wrapper: Could not determine which compiler to use. Invalid CTARGET or CTARGET has no selected profile.
|
Because of this 'emerge' fails. In my case, 'kdebase-3.5.3' cannot be installed.
Anybody has ideas what gives?
PS. 'emerge --info':

try running
gcc-4.1.1
and see if you have it installed. |

Yes, 'gcc-4.1.1' works: it produces working executables. It seems to be the same as 'i686-pc-linux-gnu-gcc'.
I emerged old gcc-config:
| Code: | # emerge =gcc-config-1.3.13-r2
|
It removed the old one (gcc-config-2.0.0_rc1) and now 'gcc' (version 4.1.1) works again like a charm 
So I think the problem was with the new gcc-config.
Unfortunately, 'gfortran' doesn't work. But 'gfortran-4.1.1' does work. Too bad there is no 'gfortran-config' 
| Code: | $gfortran
gcc-config error: gfortran wrapper: Could not determine which compiler to use. Invalid CTARGET or CTARGET has no selected profile.

There have been a few problems with the new gcc-config and eselect-compiler. I'd suggest masking them for now and filing a bug about it (as long as you can't find a similar one - I couldn't, at least).

I'm curious why you don't have a default CTARGET set. Do:
eselect compiler set -n 1

CTARGET disappeared when I emerged sys-devel/gcc-config-2.0.0_rc1
Trying 'eselect compiler set' multiple times with various options didn't help:
after each invocation CTARGET was undefined.
I had to mask sys-devel/gcc-config-2.0.0_rc1 and go back to sys-devel/gcc-config-1.3.13-r2.
Everything is OK since then: the compilers work without complaints (unlike before).
I'm using gcc-3.4.6 as a default gcc but gcc-4.1.1 also works when called by name. |

set assumes --native if you don't have a native set. Please try passing '-n' to force it, but before doing that, please tell me the output of:
/usr/libexec/eselect/compiler/profile-manager get-profiles | grep COMPILER_CONFIG_DEFAULT_CTARGET

Here it is:
| Code: | $/usr/libexec/eselect/compiler/profile-manager get-profiles | grep COMPILER_CONFIG_DEFAULT_CTARGET
COMPILER_CONFIG_DEFAULT_CTARGET="i486-pc-linux-gnu"

why didnt u just do this?
| Quote: | Code Listing 3.4: Upgrading GCC
# emerge -uav gcc
(Please substitute "i686-pc-linux-gnu-3.4.5" with the GCC
version and CHOST settings you've upgraded to:)
# gcc-config i686-pc-linux-gnu-3.4.5
# source /etc/profile |
worked fine for me, didnt use no autoselcter

Ok, and what do you have for:
eselect compiler show --ctarget="i486-pc-linux-gnu"
If it shows "(none)", then you don't have a compiler for that ctarget selected. Please do:
eselect compiler list
then select one of the i486 compilers. If you don't have any, then select one of them and use 'eselect compiler set -n <profile>'
to choose that one as default

Indeed
eselect compiler show --ctarget="i486-pc-linux-gnu"
responded with "(none)".
So I did:
eselect compiler list
and got:
[1] i686-pc-linux-gnu-3.4.6/hardened
[2] i686-pc-linux-gnu-3.4.6/hardenednopie
[3] i686-pc-linux-gnu-3.4.6/hardenednopiessp
[4] i686-pc-linux-gnu-3.4.6/hardenednossp
[5] i686-pc-linux-gnu-3.4.6/vanilla
[6] i686-pc-linux-gnu-4.1.1/vanilla
So I did:
eselect compiler set -n 5
Now:
eselect compiler show
gives:
i686-pc-linux-gnu-3.4.6/vanilla
So everything seems fine. But:
eselect compiler show --ctarget="i686-pc-linux-gnu"
gives:
(none)
In any case, both gcc-3.4.6 and gcc-4.1.1 work. gcc -v says it's gcc-3.4.6
so I'm happy. But I have a vague feeling something doesn't quite
connect somewhere...
Thank you eradicator for your help. |

I'm still confused why you have none for ctarget=i686-*. Could you please tell me the full output of:
/usr/libexec/eselect/compiler/profile-manager get-profiles

Ah ok... it appears there is a bug with eselect compiler show --ctarget="<blah>"
Thanks

I get the same problem with gcc-config-2.0.0_rc1/eselect-1.0.2
| Code: |
eselect compiler show
x86_64-pc-linux-gnu-4.1.1/amd64-vanilla
|
| Code: |
eselect compiler show --ctarget="x86_64-pc-linux-gnu"
(none)

I started my first ever gentoo build this past thursday.  So it's day 6 in my journey into the headaches of upgrading.
I have to be honest, installing Gentoo went quick by the guide in the doc's section. I wanted to upgrade to GCC 4.1.1, and started running into an entire series of challenges. P3t3r's problem was my most recent one. I finished emerge -e world, and now that I'm ready to put on PHP, I get the can't compile error.
The fix p3t3r mentioned took care of my problem entirely. Thanks. 
kind of silly I have to downgrade from eselect back to gcc-config though.
