pkg-config config error

[hedayat]

In libhttpserver.pc.in there is this line:
Libs: -L${libdir} -lmicrohttpd

Which should be
Libs: -L${libdir} -lhttpserver
instead.

I think microhttpd as a dependency should be included as well. So:
Libs: -L${libdir} -lmicrohttpd -lhttpserver

[hedayat]

I don't think so. According to pkg-config man page, libmicrohttpd should be added to "Requires" (or maybe Requires.private).

No relevant anymore as the lib doesn't use pkg-config

I think this might still be relevant...

In my case, I am implementing an HTTP service using this library. My code uses the meson build system, which as far as I can tell, figures out how to link against libhttpserver by reading the libhttpserver.pc pkg-config file installed by homebrew.

If I:

1. Install libhttpserver, meson, and ninja (I'm on OSX 10.14 Mojave):
   brew install libhttpserver meson ninja

2. Create a file called bug.cxx with the following contents:

#include "httpserver.hpp"

int main() {
    httpserver::webserver server = httpserver::create_webserver();
    return 0;
}

and a file named meson.build containing:

project('bug', 'cpp', default_options : ['cpp_std=c++11'])
dep_libhttpserver = dependency('libhttpserver')
executable('bug', 'bug.cxx', dependencies : dep_libhttpserver)

in an empty directory, and then

3. attempt to build by running:

meson build
ninja -C build

I get:

ninja: Entering directory `build'

ninja: build stopped: subcommand failed.

Changing the Lib: line in libhttpserver.pc as suggested by @hedayat gives me a working build.

Taking a look

Fix is on head

Thanks!
