Subject: | [libmicrohttpd] Trying to get the hellobrowser example to work |
Date: | Sun, 24 May 2009 22:53:58 -0500 |
Greetings. I’m relatively new to C/C++ and I’m trying
to get the hellobrowser example to work. I’m using libmicrohttpd-0.4.2
and my environment is Kubuntu 9.04 with Kdevelop 3.5.3. I start a new C++
project and insert the contents of /doc/examples/hellobrowser.c. That tells me
I need to get platform.h and microhttpd.h, so I grab those from /src/include/,
along with plibc.h and put them in my program’s src directory. I then
find that I need MHD_config.h. I find a file with that name and a “.in”
extension in the root of the downloaded file, so I rename it and copy to my
program’s src directory. Next, when I try to build the app, I get these errors: ts3.o: In function `main': /home/lance/TS3/src/ts3.cpp:31: undefined reference to
`MHD_start_daemon' /home/lance/TS3/src/ts3.cpp:37: undefined reference to
`MHD_stop_daemon' ts3.o: In function `answer_to_connection(void*,
MHD_Connection*, char const*, char const*, char const*, char const*, unsigned
int*, void**)': /home/lance/TS3/src/ts3.cpp:18: undefined reference to
`MHD_create_response_from_data' /home/lance/TS3/src/ts3.cpp:19: undefined reference to
`MHD_queue_response' /home/lance/TS3/src/ts3.cpp:20: undefined reference to
`MHD_destroy_response' I find that I can resolve the undefined reference messages
by locating each of those functions in microhttpd.h, removing the trailing semi
colon, and adding a { } to it. I figured this was something to do with C code
in C++, although I now realize the problem is deeper. That resolves my errors, I can built the program, it starts,
but isn’t listening on the port like it should be. I then notice that the
functions in microhttpd.h don’t seem to do anything. I look around and
notice that in the folder /src/daemon/ there are a bunch of .c and .h files
that look useful, but I have no idea how to use them. I’m lost here. Any insight would be much appreciated. Thanks, Lance |
