My question is: Only when I set the crosstool-ng to build a GCC 11.1 I got this erros message:

Dwarf Error: found dwarf version '5', this reader only handles version 2, 3 and 4 information.

Could this cause problems? Should I use GCC 10 to avoid this above error?
Is there a way to get a GCC 11.1 working with my configurations?

• Linux Kernel 2.6.32
• Glibc 2.23
• armv6

Here is my .config file.
ct_config_GCC_11.1_glib-2.23.txt

CrossTool-Ng version: latest (cloned from master today 30 June 2021) I think that is 1.24.0
Host OS: Ubuntu 20.04 LTS x64
Target/sample used: arm-unknown-linux-gnueabi

Hi, I for some reason I cannot see your config file.
What version of the binutils you are using?
Could you try to lower the binutils version and check if that'd fix your issue?

Look for the DWARF 5 related info here https://gcc.gnu.org/gcc-11/changes.html

Hi, I'm using:

CT_BINUTILS_V_2_26=y
CT_BINUTILS_VERSION="2.26.1"

This is the lower version of Binutils in the current master version of Crosstool-ng.

In this page above, I saw:

To make GCC 11 generate an older DWARF version use -g together with -gdwarf-2, -gdwarf-3 or -gdwarf-4.

But I cannot localize where to put the -gdwarf-4 inside the Crosstool-ng.
Could you help me?

[nikkon-dev]

If that's a GLibc related flag, you may update GLIBC_EXTRA_CFLAGS in the config.

what about install another type of gcc? I just has the same issue while i was build a c++ project in centos. And my solution is trying to install lower gcc type
