Re: Confirm Installed Run-Time Version

[richard boaz <ivor boaz gmail com>]

hi john,

well that explains the dearth of google results, thanks.

i have to do this for MAC platforms as well, (where installing gtk+ is a right-old PITA), so i will use solution 2 and simply provide all the necessary gtk+ libraries as part of the app install itself.

however, as you note, this is a cumbersome burden i don't want to have to unnecessarily suffer on LINUX as well. �so, i've gone for a third option, namely:

• use a program (listing below) to confirm that the installed version conforms to minimum requirements, outputing:
• "TRUE" = minimum version satisfied
• "FALSE" = minimum version not satisfied
• executed by installer at beginning, inspecting/analyzing output and proceeding accordingly (or not)

cheers,

richard

====== VERSION CHECK BEGIN ========

#include <gtk/gtk.h>

// minimum version required = 2.14.0

#define GTK_MAJOR_VER_MIN 2

#define GTK_MINOR_VER_MIN 14

#define GTK_MICRO_VER_MIN 0

#define SUCCESS "TRUE"

#define FAILURE "FALSE"

int main(int argc, char **argv)

{

� const gchar *verCheck = gtk_check_version(GTK_MAJOR_VER_MIN,�

� � � � � � � � � � � � � � � � � � � � � � � GTK_MINOR_VER_MIN,

� � � � � � � � � � � � � � � � � � � � � � � GTK_MICRO_VER_MIN);

� printf("%s\n", (verCheck ? FAILURE : SUCCESS));

� return 0;

}

====== VERSION CHECK END ========

I think you have two possible solutions.

The easiest is to make a useful and popular program and simply let
other people package it for you for the various distributions. I think
this is probably the only way to safely link to the users existing set
of packages without having to do a crazy amount of work.

Second best is to do what people do on OS X and Windows and bundle the
libs you use with your program, plus a wrapper script that makes your
program pick up your gtk rather than the host one (if any). This is
what firefox does, for example. You'll find this is a lot of work,
sadly.

There are projects which aim to provide cross- Linux binary packaging
systems, but I've not tried any of them.
