I've downloaded source tarball of Vala 0.22, compiled and install it but no effect... :-/ I was wondering if it was not a system problem. But I can not admit that I would have to reinstall linux to make it work. I'll search for reinstall only glib Thanks Raum > Seems like it is problem with glib2 package, try to reinstall it, I can't > say how it exactly called in Ubuntu, because I'm not an Ubuntu user. > > > > From: > raum@no-log.orgSent: > ??, > 26 > ?? > 2013 > ?. > 22:17To: > vala-list@gnome.orgSubject: > Re: > [Vala] > [Fwd: > Binary > File > is > not > seekable > ?!?] > Hello, > > Let me explain.

The example code runs fine on Arch ia32, x86_64, arm7 and Ubuntu 13.04 (ia32, x86_64) for me. -jh ___ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
Re: [Vala] [Fwd: Binary File is not seekable ?!?]
Hello, Let me explain. I want to create a tool for Linux and Windows. I need to open a binary file and seek to a position... With MingW on Windows, it runs without error but on Linux, I've a "seekable" error with the same code, same compile options, etc. I dont understand why... # Code public void main() { try { File file = File.new_for_path ("test.pcap"); DataInputStream dis = new DataInputStream (file.read ()); stdout.printf("seekable: %s\n",(dis.can_seek())?"true":"false"); } catch (Error e) { } } # WINDOWS 32bits / MingW32 $ valac --pkg gio-2.0 seek.vala $ ./seek seekable: true ## LINUX -Ubuntu 13.03- 64 bits $ valac --pkg gio-2.0 seek.vala $ ./seek (process:8097): GLib-GIO-CRITICAL **: g_seekable_can_seek: assertion `G_IS_SEEKABLE (seekable)' failed seekable: false Do you have an idea why it's running on Windows but not on Linux ?
