Hi, I am trying to use GOption feature in my program to pass command line arguments. However, when I try to use GOption functions I am getting the following error. g++ -g -O2 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -o param param-scanner.o param.o param-driver.o param-parser.o param.o: In function `main':./param.cc:17: undefined reference to `g_option_context_new' :./param.cc:18: undefined reference to `g_option_context_add_main_entries' :./param.cc:19: undefined reference to `g_option_context_parse' :./param.cc:20: undefined reference to `g_option_context_free' :./param.cc:22: undefined reference to `g_print' collect2: ld returned 1 exit status I found that GOption is only available in Glib>=2.6 and I checked it in configure.ac and and found it is available. However, it is only failing to locate above functions. Other GOption types referred correctly.(ex: gboolean,GOptionEntry,GOptionContext) Please let me know your thoughts on this?
