newbie -- using old version -- cannot build hello_world

[nelson]

I am using v3.2.2 of esp-idf.

On Windows 10, using the Mingw32 Git bash shell, I go to the `esp-idf/examples/get-started/hello_world` folder and run make. I get the following output.

Code: Select all

make[1]: Entering directory '/home/nelson/esp/esp-idf/tools/kconfig'
bison -t -l -p zconf -o zconf.tab.c /home/nelson/esp/esp-idf/tools/kconfig/zconf.y
bison: m4 subprocess failed
make[1]: *** [Makefile:344: zconf.tab.c] Error 1
make[1]: Leaving directory '/home/nelson/esp/esp-idf/tools/kconfig'
make: *** No rule to make target '/home/nelson/esp/esp-idf/tools/kconfig/conf-idf', needed by '/home/nelson/esp/esp- 
idf/examples/get-started/hello_world/build/include/config/auto.conf'.  Stop.

Obviously bison's m4 subprocess failed.

Can anyone help me figure out what is set up wrong?
Any suggestions on what to check?
