Problem building the sources

[lubertRoft]

Hi guys,

I am trying to install lgpio according to the docs, but unfortunately I am getting the following compile errors when I "make" the project. I also tried to use the commented CFLAGS in the Makefile, which did not help. I am building it on a raspi 4b running Ubuntu Server.

Here are the errors I am getting:

gcc -O3 -Wall -pthread -fpic -c -o lgCtx.o lgCtx.c
gcc -O3 -Wall -pthread -fpic -c -o lgDbg.o lgDbg.c
gcc -O3 -Wall -pthread -fpic -c -o lgErr.o lgErr.c
gcc -O3 -Wall -pthread -fpic -c -o lgGpio.o lgGpio.c
