Hello, when installing FATCAT under Ubuntu 20.94, I get the following:

make: *** [Makefile:27: AFPchain.o] Error 1

Could you please let me know how to fix this? Thanks!

davidhbrann commented 2 years ago

I received the same error, but was able to install it after using gcc/g++ 4.8.5 instead of 6.2.0 or 9.2.0

lucajovine commented 2 years ago

Thanks for the reply, but where to find a distribution of that gcc/g++ version for 20.04? Alternatively, I suppose I can simply use the executables within the FATCAT-dist/FATCATMain directory... or?

krcurtis commented 1 year ago

I had success in compiling and checking the example describe in the Install file when specifying which C++ standard to use to the Makefile: CCOPT = -O2 -Wall --std=c++03 and changing the line about #include <string> to #include <cstring> in basic.h. I'm not entirely sure if those are quite the correct changes to make though.
