Problem compiling boost

[misterxx]

Hello community

When updating the system, gcc was updated from 13.3.1_p20241025 to 14.2.1_p20241221. Now I am about to carry out the steps according to the instructions https://wiki.gentoo.org/wiki/Upgrading_ ... de-general. The instruction

#revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc

fails when compiling boost.

Code: Select all

The problem seems to be that it is still not correctly referenced to /usr/lib/gcc/..

Code: Select all

b2: /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/13/libstdc++.so.6: version `CXXABI_1.3.15' not found (required by b2)

Code: Select all

matrixstorage /usr/lib/gcc # l
insgesamt 8,0K
drwxr-xr-x 3 root root 4,0K  9. Nov 2023  armv7a-hardfloat-linux-gnueabi/
drwxr-xr-x 3 root root 4,0K 18. Mär 20:46 armv7a-unknown-linux-gnueabihf/

it should be referred to as follows:

Code: Select all

matrixstorage /usr/lib/gcc/armv7a-unknown-linux-gnueabihf/14 # l libstdc++.so.6
lrwxrwxrwx 1 root root 19  7. Apr 21:40 libstdc++.so.6 -> libstdc++.so.6.0.33*

but gcc seems to be set correctly:

Code: Select all

matrixstorage /usr/lib/gcc/armv7a-unknown-linux-gnueabihf/14 # gcc-config -l
 [1] armv7a-unknown-linux-gnueabihf-14 *

Does anyone know what the problem could be and what I could try to solve it?

gcc-cofnig shows just the version 14

Code: Select all

matrixstorage /usr/lib/gcc # gcc-config -l
 [1] armv7a-unknown-linux-gnueabihf-14 *
matrixstorage /usr/lib/gcc # 

But some packages does still refer to 13, for example

Code: Select all

misterxx@matrixstorage ~/.config $ vncserver :1
Using desktop session xfce

New 'matrixstorage:1 (oleg)' desktop is matrixstorage:1

Starting desktop session xfce

/usr/bin/Xvnc: /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/13/libstdc++.so.6: version `CXXABI_1.3.15' not found (required by /usr/bin/Xvnc)

It must be a problem with toolchain. But there is nothing to rebuild.

Code: Select all

matrixstorage /usr/lib/gcc # revdep-rebuild -p
 * This is the new python coded version

Someone an idea?

The cause of the problem was probably the CHOST variable commented out in make.conf. It was commented out when the profile was changed from 17.0 to 23.0.

I commented it back in and recompile the relevant packages ...

Let's see if it helps
