Crossover Linux

CrossOver Linux allows you to install many popular Windows productivity
applications, plugins and games in Linux, without needing Microsoft Operating System license. Once installed, your application mix with Gnome or KDE environment. Just click and run your application, just like yangAnda do on Windows, but with full freedom of Linux.

Compatibility

CrossOver Linux lets you use many Windows plugins directly
from your Linux browser.Plugin works on any Linux distribution based
x86 and will integrate with most browsers including Firefox, Netscape, Konqueror, Mozilla, and Opera. CrossOver also integrates with Gnome and KDE to let you transparently open Word, Excel or PowerPoint files. But even better, you can open these attachment types directly from the mail client.


CodeWeavers aim is to make Unix (including Linux and Mac OS X) and Windows-compatible operating systems entirely. All must be able to run Windows applications on Unix: clean, harmonious, in the native environment, and without using an emulator. For that, we maintain a Center Compatibility. Here, you can learn the exact status of a given Windows application vis-à-vis the CrossOver. We also hope you will join us in helping to support your applications in CrossOver.

There are approximately 7463 Windows applications supported by CrossOver order to work properly on Linux or Mac Os X.

kompile kernel Fedora 12 ( online & offline )

Cara mengupgrade kernel Linux di Fedora 12

berikut ini kompilasi kernel Linux untuk Fedora 12 secara offline dan online.

Langkah-langkah compile kernel Fedora 12 secara offline sebagai berikut:

1.Setelah source kernel di-download, copy ke direktori lokasi source kernel di /usr/src/kernels.

Ini adalah lokasi source kernel yang digunakan pada Fedora 12

# cp /home/umar2972/Download/linux-2.6.34.tar.bz2 /usr/src/kernels/

2. Masuk ke direktori tersebut
# cd /usr/src/kernels/


3. Ekstrak tarbal source kernel
# tar xvjf linux-2.6.34.tar.bz2

4. Masuk ke direktori hasil ekstraksi
# cd linux-2.6.34

5. Mulai konfigurasi kernel, jalankan command:
# make menuconfig


6. Akan muncul window konfigurasi kernel. Untuk kepentingan upgrade, kita gunakan saja

konfigurasi default kernel supaya lebih mudah. Pilih Exit dan Save untuk menyimpan

konfigurasi.


7. Jalankan kompilasi:
# make


8. Membuat image vmlinuz dengan command:
# make bzImage


9. Membuat module aktif yang sudah dikompilasi:
# make modules

10. Instal module dengan command:
# make modules_install


11. Sampai disini kita hanya perlu instal kernel yang baru di GRUB (boot loader default Fedora

12). Gunakan command:
# make install


Silahkan check file konfigurasi GRUB di /etc/grub.conf, disitu akan muncul konfigurasi untuk

menjalankan kernel baru kita.


Langkah-langkah compile kernel Fedora 12 secara online sebagai berikut:

Sebelum mengupdate kernel yang baru install telebih dahulu gcc nya dengan perintah sebagai berikut :

# yum install gcc

Setelah itu update kernel yang baru dengan perintah :

# yum –y install devel*.*

Kemudian kernel headernya :

# yum install kernel-header*.*

Cara meremove kernel yang lama :

# cat /etc/yum.conf

Search kernel yang ada :

# rpm –q | grap kernel

Remove kernel yang diinginkan dengan perintah :

# yum remove ( versi kernel )
