[Ovmsdev] Error compiling simcom and lwip

[Mark Webb-Johnson]

I just tried a full ‘make clean; make' re-compile on mine, and it worked fine.

Can you check:

1. ESP-IDF version

$ cd ~/esp/esp-idf

$ git status
On branch release/v2.1
Your branch is up-to-date with 'origin/release/v2.1'.
nothing to commit, working tree clean

$ git remote -v
origin	https://github.com/openvehicles/esp-idf.git (fetch)
origin	https://github.com/openvehicles/esp-idf.git (push)

2. Version of xtensa crosstool-NG

$ xtensa-esp32-elf-c++ -v 2>&1 | tail -1
gcc version 5.2.0 (crosstool-NG crosstool-ng-1.22.0-61-gab8375a)

Then check 'git diff sdkconfig.default sdkconfig’ in your OVMS tree, to make sure that looks ok. Perhaps you don’t have PPP enabled?

$ fgrep PPP sdkconfig
CONFIG_PPP_SUPPORT=y
CONFIG_PPP_PAP_SUPPORT=y
CONFIG_PPP_CHAP_SUPPORT=y
# CONFIG_PPP_MSCHAP_SUPPORT is not set
# CONFIG_PPP_MPPE_SUPPORT is not set
# CONFIG_PPP_DEBUG_ON is not set

And also that your OVMS tree is up-to-date?

Regards, Mark.
