But i don't know how to modify the makefile and how to include the this is a example when using the library. g++ -o normFileRecv normFileRecv.cpp -D_FILE_OFFSET_BITS=64 -I../common/ \ -I../protolib/include -I../include/ ../lib/libnorm.a ../protolib/lib/libprotokit.a \ -lpthread the third-party libraries include libnorm.a, libprotokit.a, and lpthread. and the include files are under the directory of common and protolib/include. If i want to involve the API in the file: src\mpid\ch3\channels\nemesis\src\Ch3-istartmsg.c how should i modify the makefile? I am really appreciate your help.
