#10 Error in building arpca.c

[Ilario Gelmetti]

Hi!
I just downloaded the latest code following the git instructions from the readme.
Then, following the build instructions I had the following error:

$ make
[  5%] Building C object src/CMakeFiles/arpon.dir/arpca.c.o

    inlined from ‘arpca_overwrite’ at /home/ilario/software/arpon/src/arpca.c:373:13:

make[1]: *** [CMakeFiles/Makefile2:242: src/CMakeFiles/arpon.dir/all] Error 2
make: *** [Makefile:136: all] Error 2

Then I applied the patch included in #1 and the error remained.

The file CMakeCache.txt in the build directory has a place to add CFLAGS, change it to include:

CMAKE_C_FLAGS:STRING=-Wno-error=stringop-truncation -Wno-error=implicit-fallthrough -Wno-error=pointer-compare
