Error compiling darknet

[ABesginow]

Hello Lars,

while compiling the darknet directory (Step. 5), I get the following error:

> make
g++ -Iinclude -Isrc -DOPENCV -I/opt/opencv320/include/opencv -I/opt/opencv320/include -Wall -Wfatal-errors -fPIC -Ofast -DOPENCV -c ./src/wrapper_c.c -o obj/wrapper_c.o
./src/wrapper_c.c: In function ‘void setup_network(const char*, const char*)’:
./src/wrapper_c.c:26:36: error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive]
     net = parse_network_cfg(cfgfile);
                                    ^
compilation terminated due to -Wfatal-errors.
Makefile:68: recipe for target 'obj/wrapper_c.o' failed
make: *** [obj/wrapper_c.o] Error 1

Suddenly, the above is compiling....

But ~100 lines later, there is a different error for the same file:

./src/wrapper_c.c: In function ‘detect_img’:
./src/wrapper_c.c:158:16: warning: implicit declaration of function ‘ipl_to_image’ [-Wimplicit-function-declaration]
     image im = ipl_to_image(src);
                ^
./src/wrapper_c.c:158:16: error: invalid initializer
compilation terminated due to -Wfatal-errors.
Makefile:68: recipe for target 'obj/wrapper_c.o' failed
make: *** [obj/wrapper_c.o] Error 1

In my understanding, it is not including the "image.h" file correctly, but I am not sure why.

Is there a way to fix this? Any help is appreciated!

Thanks in advance!

regards Andreas

Too little too late I'm sure, but the problem is that in the image.h file the declaration of ipl_to_image() is contained within an #ifdef OPENCV. So if OPENCV is not defined, then you will get this error. Hopefully this helps someone else.
