Setup Toolchain for Mac OS from Scratch - multiple problems

[ghost]

OK so I am trying to get the esp IDF installed on OSX.

First problem is described here: https://github.com/espressif/esp-idf/issues/2600

So I then think OK well maybe if I build the toolchain from scratch it might get around the above problem.

So I follow these instructions: https://docs.espressif.com/projects/esp-idf/en/latest/get-started/macos-setup-scratch.html

$ git clone -b xtensa-1.22.x https://github.com/espressif/crosstool-NG.git
**fatal: destination path 'crosstool-NG' already exists and is not an empty directory.**

So I get around this by first doing: cd ~/esp/crosstool-NG/

Then: git clone -b xtensa-1.22.x https://github.com/espressif/crosstool-NG.git

Then: cd ~/esp/crosstool-NG/crosstool-NG/

I then do:

$ ./bootstrap && ./configure --enable-local && make install
**-bash: ./bootstrap: /bin/sh^M: bad interpreter: No such file or directory**

Can anyone please suggest what I can do to get the idf installed on OSX?

thanks

Since the original issue is related to building mconf, building the toolchain from scratch is not going to resolve that.

Thanks for pointing out the mismatch between crosstool-NG directories, will fix this.

However this error messages likely explains the issue:

-bash: ./bootstrap: /bin/sh^M: bad interpreter: No such file or directory

There is an extra CR symbol at the end of the line, indicated by ^M. This can happen if your git is configured to check out files with CRLF line endings... which isn't a common thing to do on macOS. This can also happen when you clone the repository on Windows and later use it under macOS (when dual booting). Given the description of the issue, the former is more likely to be the case.

Could you please run the following (in crosstool-NG repository) and see if there's anything related to core.autocrlf?

git config --list

Seems to have fixed it thanks!
