Re: [Vala] [ANNOUNCE] Vala 0.9.6 - Compiler for the GObject type system

Hello 
Thanks for reply!
Is it really the solution to manually set LD_LIBRARY_PATH every time?
This is not recommended from various sources (e.g.
http://linuxmafia.com/faq/Admin/ld-lib-path.html)
Also this wasn't necessary in the past. So why now?

Hello Christer

Something has changed.



Since vala 0.9.5, the suffix 1.0 is replaced by 0.10

Christers mail:
All versions including 0.9.6 have worked for me. Here is my output from
ldd
if it helps:

ldd /usr/bin/valac

    linux-gate.so.1 =>  (0xb7732000)
    libvala-0.10.so.0 => /usr/lib/libvala-0.10.so.0 (0xb7479000)
    libgobject-2.0.so.0 => /usr/lib/libgobject-2.0.so.0 (0xb743b000)
    libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0xb7373000)
    libpthread.so.0 => /lib/libpthread.so.0 (0xb7359000)
    libc.so.6 => /lib/libc.so.6 (0xb720d000)
    libgthread-2.0.so.0 => /usr/lib/libgthread-2.0.so.0 (0xb7209000)
    librt.so.1 => /lib/librt.so.1 (0xb7200000)
    libpcre.so.0 => /lib/libpcre.so.0 (0xb71c9000)
    /lib/ld-linux.so.2 (0xb7733000)





There seems to be a problem with the current release. Typing valac into
the terminal gives:

$ valac
valac: error while loading shared libraries: libvala-0.10.so.0: cannot
open shared object file: No such file or directory

The problem didn't exist with vala-0.9.4, which is the last version
before 0.9.6 that I used.

Anybody else has this issue?

We are pleased to announce version 0.9.6 of Vala, a compiler for the
GObject type system.

Vala 0.9.6 is now available for download at:
   http://download.gnome.org/sources/vala/0.9/

Changes since 0.9.5
 * Drop deprecated support for assigning to construct properties.
 * Some refactoring in the code generator.
 * Bug fixes in bindings and vapigen.

Vala is a new programming language that aims to bring modern programming
language features to GNOME developers without imposing any additional
runtime requirements and without using a different ABI compared to
applications and libraries written in C.

valac, the Vala compiler, is a self-hosting compiler that translates
Vala source code into C source and header files. It uses the GObject
type system to create classes and interfaces declared in the Vala source
code.

The syntax of Vala is similar to C#, modified to better fit the GObject
type system. Vala supports modern language features as the following:

        * Interfaces
        * Properties
        * Signals
        * Foreach
        * Lambda expressions
        * Type inference for local variables
        * Generics
        * Non-null types
        * Assisted memory management
        * Exception handling

Vala is designed to allow access to existing C libraries, especially
GObject-based libraries, without the need for runtime bindings. All that
is needed to use a library with Vala is an API file, containing the class
and method declarations in Vala syntax. Vala currently comes with
bindings for GLib and GTK+. It's planned to provide generated bindings for
the full GNOME Platform at a later stage.

Using classes and methods written in Vala from an application written in
C is not difficult. The Vala library only has to install the generated
header files and C applications may then access the GObject-based API of
the Vala library as usual. It should also be easily possible to write a
bindings generator for access to Vala libraries from applications
written in e.g. C# as the Vala parser is written as a library, so that
all compile-time information is available when generating a binding.

More information about Vala is available at
