Need help compiling crypto++

rain (84)
Hello I am trying to compile test.cpp which is built-in test file in crypto++ library. I have made makefile but it does not work.

"D:/Dropbox/cpp/praks/praks8" is in my case directory where all the crypto++ cpp and h files are.

It looks like you forgot to actually link to the static library. You only added the search directory with -L. I expect it should be -lcryptopp or something.

"D:/Dropbox/cpp/praks/praks8" is in my case directory where all the crypto++ cpp and h files are.


And does it also contain the library file, probably named libcryptopp.so or libcryptopp.a ?

Some things about your make file not related to your problem.

# If you use clang++, make sure the following line does not start with a comment (#)
CXX=g++


Should that be:

CXX = clang++

to use clang ?

# -Wall 	shows all warnings when compiling, always use this!
