In my project I have the following structure :
.
├── Makefile
├── include
│ ├── Game.h
│ ├── Game.h.gch
│ └── Letter.h.gch
├── letra_A_.png
├── main.cpp
├── modules
│ └── Game.cpp
└── resources
└── space.bmp
3 directories, 8 files
And my Makefile contains :
#Makefile for SDL universe
SOURCES := $(shell find . -name \*.cpp -o -name \*.h)
build:
echo "Building.."
g++ -L/usr/include -lSDL2 $(SOURCES) -o blocks
echo "Done"
The problem I am seeing is that it only works in one machine among the two I have. The one which is working fine has Kali Linux while the one where it fails has Ubuntu 18.10.
I can see SDL2 is installed in the same exact location in both distros :
(0) matias #> ls -ldh /usr/include/SDL2/
drwxr-xr-x 2 root root 4.0K Oct 28 11:27 /usr/include/SDL2/
Why is my project not building in Ubuntu? Im getting the below error :
./main.cpp: In function ‘int main()’:
./main.cpp:11:51: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
