[libmicrohttpd] Trying to get the hellobrowser example to work

[Lance Lefebure]

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
