Cmake Problem

Hi my cmake give error can u help me ?

It sounds like you need to include hardware-mapping.c in the sources. Maybe you missed it because the other files are *.cc, and this is the only c file.

[K0rkunc]

Kaynaklara donanım-mapping.c eklemeniz gerekiyor gibi görünüyor. Belki diğer dosyalar *.cc olduğu için kaçırdınız ve bu tek c dosyası.

Zeller fixed framebuffer but now gives new error

The word "regular" needs to be a string, so maybe you have to extra-quote it in cmake, maybe with single quotes around? '"regular"'

[K0rkunc]

i tried single but again same problem

[K0rkunc]

how to setup standart regular hw map ?

[hzeller]

If you give the cmake call a -DCMAKE_VERBOSE_MAKEFILE=true parameter, it will output the full compiler command line when compiling, so it will be easier to diagnose what is wrong.

Ideally the compiler calls then have a -DDEFAULT_HARDWARE='"regular"', so a single-quoted thing around the double-quoted string. So you essentially you have to find out how to pass a literal string in a cmake CXX_FLAGS.

If you look at the output of the Makefile that comes with the project, there you see how such a compiler call looks like

g++ -I../include -W -Wall -Wextra -Wno-unused-parameter -O3 -g -fPIC  -DDEFAULT_HARDWARE='"regular"' -fno-exceptions -std=c++11 -c -o led-matrix.o led-matrix.cc

[hzeller]

Also, if you don't pass the DEFAULT_HARDWARE define, the code should automatically default to "regular". Probably the simplest solution for you, just remove the -DDEFAULT_HARDWARE="regular" in your cmake CXX_FLAGS setting.

yes master, i tried that, now unfortunately i got such an error this time

The matrix_hardware_mappings is defined in the C-file as mentioned above . So you have to add that in your cmake file

file(GLOB_RECURSE RGB_SRC_FILES lib/*.cc lib/*.c)

[K0rkunc]

matrix_hardware_mappingsC-dosyasında tanımlanır yukarıda bahsedilen . Yani bunu cmake dosyanıza eklemelisiniz

file(GLOB_RECURSE RGB_SRC_FILES lib/*.cc lib/*.c)

sir you are amazing!!

lib and thank you very much for your help.

I've included it below if anyone wants to use it. CMAKE EXAMPLE

add_executable(kickass main.cc ${HW_HEADER_FILEs} ${RGB_SRC_FILES} ${RGB_HEADER_FILES} ${SRC_FILES} ${HEADER_FILES})
