cross-gdb build fails

[horvathp]

On OS X, with the latest master, [ERROR] /Volumes/ESPToolchain/esp-open-sdk/crosstool-NG/.build/src/gdb-7.10/gdb/guile/scm-ports.c:231:47: error: incomplete definition of type 'struct scm_t_port'

Is this a known issue?

I have very similar issue on linux:

Same. It seems to be due to this: https://sourceware.org/bugzilla/show_bug.cgi?id=21104 Edit: see also https://github.com/crosstool-ng/crosstool-ng/issues/718

[flannelhead]

A reasonable workaround to get the rest of the build to succeed is disabling the gdb build. It can be done by adding the line

CT_DEBUG_gdb=n

to the file crosstool-config-overrides. A proper workaround would be to somehow pass --with-guile=guile-2.0 to the gdb configure script. I'll report if I figure out how to do that.

[flannelhead]

Yep, it seems

CT_GDB_CROSS_EXTRA_CONFIG_ARRAY="--with-guile=guile-2.0"

did the trick and I was able to build also gdb. Ideally this situation should be detected on the crosstool-ng side, but this serves as a temporary workaround.

Notice that this might break the build for users with older guile. Guile 2.0 has been released in 2011 though, so this shouldn't be a major issue.

[roger-zacharczyk]

Where did you put this line?

[flannelhead]

In crosstool-config-overrides (which I mentioned in my comment right above).

[ricardoquesada]

sorry, but where should I put that file, I couldn't find it. I'm following these steps: https://docs.espressif.com/projects/esp-idf/en/stable/get-started/macos-setup-scratch.html

but I couldn't find any crosstool-config-overrides in the ~/esp folder. Thanks!

[flannelhead]

@ricardoquesada : you seem to be not using esp-open-sdk but building directly from crosstool-ng by Espressif's instructions. However, if you're getting the build failure, you can append the configuration line

CT_GDB_CROSS_EXTRA_CONFIG_ARRAY="--with-guile=guile-2.0"

to crosstool-ng's config file (located in the same folder as the ct-ng binary). Do this after running

./ct-ng xtensa-esp32-elf

but before

./ct-ng build

[ricardoquesada]

thanks @flannelhead !

I have guile 2.2 and using the following doesn't seem to fix the issue. Any idea? CT_GDB_CROSS_EXTRA_CONFIG_ARRAY="--with-guile=guile-2.2"

how can i make this workaround work if i need the 106 compiler and not the 32 one ?

seems ct-ng doesn't have a rule for xtensa-esp106-elf

edit: Nevermind! i made a typo. just do: ./ct-ng xtensa-lx106-elf

For me (using Arch Linux) using guile-2.2 didn't work either. I just installed guile-2.0 and used this.

I had the same error compiling with Ubuntu 20.04. Second fix from flannelhead (CT_GDB_CROSS_EXTRA_CONFIG_ARRAY="--with-guile=guile-2.0") did't work.

The first fix did the trick (CT_DEBUG_gdb=n)
