Latest ESP-IDF 4.0 compilation error

[jerome]

Dear all
I just updated esp-idf to the latest version and my project no longer compiles.
esp-idf version is v4.0-dev-728
I'm using wrover module

I'm facing the following errors, and cannot find anything useful after searching.

CC build/esp32/spiram_psram.o
/esp32Dev/esp-idf/components/esp32/spiram_psram.c: In function 'psram_enable':

Anybody here having the same issue ?
Thanks to all
