Re: [Vala] Header file not found ?!?
Hello, In fact, I've the same problem as : http://www.perlmonks.org/?node_id=896237 $ valac --pkg libpcap -X -I/opt/include test.vala test.vala.c: In function 'main': test.vala.c:29:2: warning: 'g_type_init' is deprecated (declared at C:\TEMP\cccVFFzy.o:test.vala.c:(.text+0x47): undefined reference to `pcap_lib_version' collect2: ld returned 1 exit status error: cc exited with status 1 Compilation failed: 1 error(s), 0 warning(s) I will try the fix explained in the web page.
