Hello,

I remember having some issues when I needed to switch to profile 23.0 from 17.0 and now gcc will not compile. I think I changed the CHOST and later changed it back.

Installing GCC gives the following error
Quote:
make[1]: *** [Makefile:24550: stage1-bubble] Error 2
which seems to indicate that GCC is not properly installed.

Code:
gcc-config -l


Quote:
* gcc-config: No gcc profile is active!
/usr/bin/gcc-config: line 104: /etc/env.d/gcc/config-armv7a-unknown-linux-gnueabihf: No such file or directory


After switching the profile I did a complete recompile of the system with emerge -E and saw GCC fail together with docker and decided it was a problem for future me.

I tried to reinstall the currently install GCC (13.2.1_p20240210) but it gives the same stage1-bubble error. What steps can I take to resolve this issue?

Thank you,
Frank.

Indicate you want to use soft-float,

Quote:
CHOST="armv7a-unknown-linux-gnueabihf"


Indicate your build server is hard-float.

As far as I know, this will require cross compile. The default will not work.

That makes sense as I was using cross-compile before. Any idea how I can resolve this? I don't want to use distcc anymore. Do I need to change the chost or the common flags?

frank0x01,

If you want to have working gcc, then check /usr/armv7a-unknown-linux-XXXX.

your CHOST should match that.

Once you have working gcc, then if you still want a soft-float toolchain, you need cross-dev and may be setup chroot to build new rootfs.

To follow up on this issue, what I eventually did was to remove the softfloat references and to comment out the CHOST variable:


Quote:

COMMON_FLAGS="-O2 -pipe -march=armv7-a" # -mfpu=vfpv3-d16 -mfloat-abi=softfp"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult https://wiki.gentoo.org/wiki/Changing_the_CHOST_variable before changing.

#CHOST="armv7a-unknown-linux-gnueabihf"

# NOTE: This stage was built with the bindist Use flag enabled

#PYTHON_TARGETS="python3_9"

# This sets the language of build output to English.
# Please keep this setting intact when reporting bugs.
LC_MESSAGES=C
#MAKEOPTS="-j25 -l4"
USE="-X acl bluetooth"
ACCEPT_LICENSE="@FREE"


After this it successfully merged gcc.
