I try to install YamCha tool for NLP tasks, like NER, POS, and chunking.
While trying to install, I followed the installation steps
% ./configure
% make
% make check
% su
# make install
I got the following error messages:-
param.cpp: In member function 'bool YamCha::Param::open(int, char**, const YamCha::Option*)': param.cpp:102:42: error: 'strlen' was not declared in this scope size_t nlen = strlen (opts[i].name); ^ param.cpp:103:68: error: 'strncmp' was not declared in this scope if (nlen == len && strncmp (&argv[ind][2], opts[i].name, len) == 0) { ^ param.cpp: In member function 'bool YamCha::Param::open(const char*, const YamCha::Option*)': param.cpp:182:28: error: 'strncpy' was not declared in this scope strncpy (str, arg, 1024); ^ param.cpp:185:12: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings] make all-recursive make1: Entering directory

There is a header file missing in your code files. The link you provided above, contains a source file src/common.h , just add #include<string.h> in this file. With this addition, it should work.
