During configuration of one project, I got the error:

checking for JSON... no

no

configure: error: 

You must have JSON-GLib >= 0.14.0 development headers installed to build.



make: *** [config.status] Error 1

The configure script contains such strings:

$ cat configure | grep json-glib

    { { $as_echo "$as_me:${as_lineno-$LINENO}: $PKG_CONFIG --exists --print-errors "json-glib-1.0 >= 0.14.0""; } >&5

  ($PKG_CONFIG --exists --print-errors "json-glib-1.0 >= 0.14.0") 2>&5

  pkg_cv_JSON_CFLAGS=`$PKG_CONFIG --cflags "json-glib-1.0 >= 0.14.0" 2>/dev/null`

    { { $as_echo "$as_me:${as_lineno-$LINENO}: $PKG_CONFIG --exists --print-errors "json-glib-1.0 >= 0.14.0""; } >&5

  ($PKG_CONFIG --exists --print-errors "json-glib-1.0 >= 0.14.0") 2>&5

  pkg_cv_JSON_LIBS=`$PKG_CONFIG --libs "json-glib-1.0 >= 0.14.0" 2>/dev/null`

            JSON_PKG_ERRORS=`$PKG_CONFIG --short-errors --print-errors --cflags --libs "json-glib-1.0 >= 0.14.0" 2>&1`

            JSON_PKG_ERRORS=`$PKG_CONFIG --print-errors --cflags --libs "json-glib-1.0 >= 0.14.0" 2>&1`

So I assumed I need package json-glib-1.0 but it seems to be installed:

$ apt-cache policy json-glib-1.0

Does anyone know which package should I install? In the case it does matter, the source is Pidgin 3.0 development branch. Everything I found in Google is only a message about changing json-glib to 0.14 version.

As raaz suggested below, I downloaded, converted and installed RPM via alien. But the configure script produces the same error, even with the newest version of package.
