Undeclared dependency on gio-unix-2.0

[Jan Tojnar]

I am building audio-recorder 2.1.3 on NixOS and getting the following error:

```
dbus-player.c:22:10: fatal error: gio/gdesktopappinfo.h: No such file or directory
 #include <gio/gdesktopappinfo.h>

Hello,

I saw on the internet some similar bug-reports related to "gio-unix-2.0" library.
Can you check

$ pkg-config --cflags gio-unix-2.0

gio-unix-2.0 is part of libglib2.0-dev package.
Ref: https://packages.debian.org/search?suite=stretch&arch=any&searchon=contents&keywords=gio-unix-2.0.pc

Have you installed "libglib2.0-dev"?.

Running `pkg-config --cflags gio-unix-2.0` in the package prints the following:

-I/nix/store/l1v16k68v3njjw281fbfk20zxsb52q35-glib-2.56.0-dev/include/gio-unix-2.0/ -I/nix/store/l1v16k68v3njjw281fbfk20zxsb52q35-glib-2.56.0-dev/include/glib-2.0 -I/nix/store/ycpkd4jxpy913v6fxf4b5mmy9bz81vsy-glib-2.56.0/lib/glib-2.0/include

I think the issue is that the gio-unix-2.0 cflags are not passed to the dbus-player.c file.

Hello,
Yes, I may agree with you.

Looks like some systems prefer gio-unix-2.0 instead of gio-2.0.
F.eks some pure Unix systems: https://developer.gnome.org/
gio/stable/ch03.html

NixOS is a Linux-distro, but the packaging and package system is different
from Debian or Fedora.

You should study two (2) options.

Option 1)
Include the glib-unix.h in the dbus-player.h or .c file.

The re-compile.

Ref:
https://developer.gnome.org/glib/stable/glib-UNIX-specific-utilities-and-integration.html

----

Option 2)
Try this.
Would you please edit the "configure.ac" and add gio-unix-2.0 to it.

Check you library version with
pkg-config --modversion gio-unix-2.0

The lines may look like this:

PKG_CHECK_MODULES(GLIB_UNIX, glib-unix-2.0 >= 2.0)
AC_SUBST(GLIB_UNIX_CFLAGS)
AC_SUBST(GLIB_UNIX_LIBS)

--------------------------------

The reset and re-configure the source:

cd audio-recorder*
make clean

aclocal
autoconf
automake -a

Or as one-liner:
aclocal && autoconf && automake -a

You may also run:
autoreconf -i
-------------

These commands will configure, build/compile, and install the program:

cd audio-recorder*
./configure
make clean
make

sudo make install # run this as root or sudo! AT LEAST ONCE.
-------------

Notice: KILL or QUIT previous instances of the program !
pkill audio-recorder

Then re-run the program
src/audio-recorder
--------------

Good luck.

I can later add necessary changes to the source on Launchpad.

It is not that some systems prefer it, but that some software requires it. For example, audio-recorder requires gio/gdesktopappinfo.h header, which is provided by gio-unix-2.0.

Apparently it works on some systems without explicitly declaring the dependency because GTK sometimes adds `-I.../include/gio-unix-2.0` to Cflags but that should not be relied on.

Regarding the options, 1) would not work since glib-unix.h header from glib-2.0 package is completely different thing from gio-unix-2.0 package. 2) is closer, it would need to be changed to correct package name (gio-unix instead of glib-unix) and the variables would need to be added to the correct Makefile.in files.

[moma (osmoma)]

Ok, I thought that Unix version of glib bundles all gio, glib, gthread, ..

May I ask if the solution is to subtitute gio-2.0 with gio-unix-2.0 in the
configure.ac ?

PKG_CHECK_MODULES(GIO, gio-2.0 >= $GLIB_REQUIRED)
AC_SUBST(GIO_CFLAGS)
AC_SUBST(GIO_LIBS)

with

PKG_CHECK_MODULES(GIO, gio-unix-2.0 >= $GLIB_REQUIRED)
AC_SUBST(GIO_CFLAGS)
AC_SUBST(GIO_LIBS)

Then run the mantra to re-configure and compile/link.

Yes, glib package on linux distributions often bundles all the libraries listed, but each library has its own pkg-config module with its set of own compiler flags.

As gio-unix-2.0 is a distinct module, it should be used where needed in addition to gio-2.0. It is needed whenever using one of the following headers:

gio
├── gdesktopappinfo.h
├── gfiledescriptorbased.h
├── gunixconnection.h
├── gunixcredentialsmessage.h
├── gunixfdlist.h
├── gunixfdmessage.h
├── gunixinputstream.h
├── gunixmounts.h
├── gunixoutputstream.h
└── gunixsocketaddress.h
