gdb version too old - needs python2.7

[anm]

I can't run esp32 gdb because python2.7 is too old for my OS. Installing the latest version direct from espressif works.

I've seen other people encountering this problem on platformio forums too.

[Jason2866]

I have nowhere an issue not using python v2.7 with GDB

Same problem in Ubuntu 24.04.

I would really appreciate if this could be fixed soon. This ancient version of python2 - support for Python 2 ended Jan. 1, 2020 see announcement on python.org - may be a security risk.

[Jason2866]

What is the exact issue? What command is not working without Python2?

ldd xtensa-esp32-elf-gdb

gdb is linked dynamically against V2 of libpython. Several distros do no longer offer V2 - so you have either to install it manuallly - as I did longer ago (and forgot that fact until today 😉) - or you get an error message due to the missing lib.

I saw in the meantime that @valeros has upgraded the python version in CI to 3.9 - so I am little bit optimistic that the next release fixes this isuue

[Jason2866]

Ahh, you are using the old version

[arduhe]

Not voluntary 😆

[calint]

I am using the latest PlatformIO (6.1.15) and have the same issue.

The Python 2 library that is no longer available in Ubuntu 24.04.

It's even worse - xtensa-esp32s3-elf-gdb shows unsurprisingly the same behaviour

ldd ~/.platformio/packages/toolchain-xtensa-esp32s3/bin/xtensa-esp32s3-elf-gdb
       linux-vdso.so.1 (0x00007ffefe7e5000)
       libdl.so.2 => /lib64/libdl.so.2 (0x00007fe6980f4000)
       libpython2.7.so.1.0 => not found
       libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fe6980f1000)
       libutil.so.1 => /lib64/libutil.so.1 (0x00007fe6980ec000)
       libm.so.6 => /lib64/libm.so.6 (0x00007fe698002000)
       libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007fe697c00000)
       libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fe697fde000)
       libc.so.6 => /lib64/libc.so.6 (0x00007fe697800000)
       /lib64/ld-linux-x86-64.so.2 (0x00007fe698123000)

But if I install the missed library manually (and nothing else from python2.7) the linkage error disappears but instead a - at a first glance - strange python error occurs

This is IMHO due to missing support of python2.7 on my system.

I was able to reproduce this behavior under 3 different distributions/installations

• openSUSE Leap 15.6 (using python3.6)
• openSUSE Tumbleweed (using python3.11)
• debian 12 (using python3.11)

For those who are waiting like me for a solution of this issue - in the meantime I've found a workaround described here - nevertheless it would be REALLY fine, if the support for PYTHON3 would be pushed forward ...

Debian Bookworm is in the same club...
