Build fails undefined reference about lampify HOT 8 OPEN

@ophirHav I will try this out tomorrow (actually I already gave up so many thanks for your reply). Can you elaborate a bit?

so changing line 9 of the makefile from:
$(CC) $(CFLAG) $(INC) $(LIB) -o $(BASE) $(BASE).c

To:
$(CC) $(BASE).c $(CFLAG) $(INC) $(LIB) -o $(BASE)

It seems you only changed the order of the parameters passed to gcc, does this mean original make file was always incorrect or did gcc change or something.
How did you arrive at this fix if I may ask?

Update: It works now, I can compile the program without errors, thank you very much!

I had to replace line 3 of the Makefile to use pkg-config to build on Ubuntu 22.04 :

INC   = -I /usr/include/glib-2.0 -I /usr/lib/glib-2.0/include -I /usr/include/gdk-pixbuf-2.0

with

INC   = $(shell pkg-config --cflags glib-2.0) $(shell pkg-config --cflags gdk-pixbuf-2.0)

to fix build fail #2
change the Makefile for the compilation to be -
$(CC) $(BASE).c $(CFLAG) $(INC) $(LIB) -o $(BASE)

Same problem with me :-(

worked for me as well :-)

Newer versions of GCC have made the order of arguments relevant for linking and optimization purposes. That's why your sources should go first and then reference libraries the code uses.

For Ubuntu 24.04 also, this worked

Yup, it built. Anyone else having the problem where it outputs [I] Connecting to the lamp [E] Failed to set advertising parameters!? I also tried running as root, but that didn't work. Also it doesn't make the light blink, and lights are unresponsive.
