Newlib does not support CPU xtensa

[jackwilsdon]

I'm experiencing an issue with compiling xtensa-lx106-elf with newlib as the standard library, as I am receiving the message "Newlib does not support CPU xtensa" whenever I run ct-ng build.

Files

• .config
• build.log (lag warning - large file)
• /tmp/xtensa-build/xtensa-lx106-elf/build/build-libc/config.log
• /tmp/xtensa-build/xtensa-lx106-elf/build/build-libc/xtensa-lx106-elf/newlib/config.log

If you need any more information please don't hesitate to ask.

possible with this fork? https://github.com/espressif/crosstool-NG

Hm... I am using espressif fork and getting the same error. Ah, perhaps the version of newlib 2.2.0 is not part of 1.22.0 release, which has 2.1.0 as the latest.

@creatica-soft you can enable ct-ng experimental features and then specify newlib repository by URL. Chosen newlib version doesn't matter in that case.
See this config for example.
