Error Building In Ubuntu 16.04 LTS crosstool-NG

make[2]: Entering directory '/home/name/Documents/esp-open-sdk/crosstool-NG' [INFO ] Performing some trivial sanity checks [INFO ] Build started 20170310.121909 [INFO ] Building environment variables [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [ERROR]

This error seems to be because it is trying to reference an old version of expat The build is successful when the file crosstool-NG/scripts/build/companion_libs/210-expat.sh is renamed to 220-expat.sh which then downloads and installs expat version 2.2.0 with no reported errors.

I am new to esp and am not sure if upgrading the version here breaks anything.

(@UlmusLeo .. just a sanity check for you) I'm also having the same issue, though I couldn't get your fix working unfortunately I also tried on my ARM machine (Chromebook + crouton) and it too fails in crosstool-NG, but at a different companion-lib

Looks like the esp-open-sdk needs an update, but I'm also new to ESP - so it's hard for me to debug the problem as well

A way to fix this issue is this pull request: https://github.com/jcmvbkbc/crosstool-NG/pull/53 This also fixes https://github.com/pfalcon/esp-open-sdk/issues/307

It boils down to update the URL template in crosstool-NG/scripts/build/companion_libs/210-expat.sh from http://downloads.sourceforge.net/project/expat/expat/${CT_EXPAT_VERSION} to https://github.com/libexpat/libexpat/releases/download/R_${CT_EXPAT_VERSION//[.]/_}
