Ii have a makefile that is pre-configured for a graphics display interface. I want to add the libgpiod interface to it, but am doing an excellent job of failing at it right now!
In the preconfigured makefile I put GPIO_DIR_LIB = -L /usr/lib/aarch64-linux-gnu which is where the libgpiod.a and libgpiod.so are located. Yet when I run the makefile, I get an error:
pi@raspberrypi:~/projects/StepperRoutines $ make -f makefile.david
( gcc -L/home/pi/glg/lib -L /usr/lib/aarch64-linux-gnu -L. -o main main.o BSP.o ADC.o Move.o \
-lglg_ext -lglg -lglg_map_stub \ -lgpiod \
-lXm -lXt -lX11 \
-lXft -lfontconfig -lfreetype -ljpeg -lz -lpng \
-lm -ldl -lpthread -lgpiod \
|| ( rm main ; exit 1 ) )
/usr/bin/ld: cannot find -lgpiod: No such file or directory
collect2: error: ld returned 1 exit status
rm: cannot remove 'main': No such file or directory
make: *** [makefile.david:163: main] Error 1
I know gpiod is loaded, because if I compile an example named blink ->gcc -o blink blink.c -lgpiod, it compiles cleanly and runs as expected.
Here is the preconfigured makefile - if anyone can break me out of the excellent job of failing, I would appreciate it. Being a Loser is such a drag!
Kind regards,
David

# INTENDED USE
#
# This makefile may be used to compile and link individual source files
# in a directory that contains several versions of the same example,
# such as examples in the examples_c_cpp/Dashboard directory.
#
# The makefile uses the X11 version of the GLG library. Use a makefile
# with the "_gtk" suffix to use the GTK version of the GLG library.
#
# USING THE FILE
#
# This file assumes GNU make is used as a make utility.
# It compiles a single .c or .cpp file (with the basename defined by
# TARGET) as well as any additional files specified by ADD_FILES.
# Edit TARGET and ADD_FILES variables as needed.
#
# This file must be edited by adjusting directory path as well as
# uncommenting additional options depending on the platform.
# By default, Linux options are used.
#
# Edit the GLG_LIB_DIR line to use either GLG EVALUATION or PRODUCT
# libraries.
