Can‘t compile esp_idf？

[xzwang]

hi,all,

I has update the esp_idf today, It has three months since last update. I try to compile the latest esp_idf but failed.
The error information is:
include/esp_assert.h:23:28: error: first argument to '__builtin_choose_expr' not a constant
_Static_assert(__builtin_choose_expr(__builtin_constant_p(CONDITION), (CONDITION), 1), #MSG); \

I have no idea how to fix the error.
Does anyone can give me some suggestion?

You probably need to update the toolchain (compiler), similar errors have been seen when compiling latest ESP-IDF with gcc 4.8.5.
Please follow the getting started guide for your platform to install new toolchain.
