Solution: Nice IDE on Ubuntu (GTK2)
lazarus / 1-Linux

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

After installing Lazarus on Ubuntu, i got the same ugly IDE
(colors,fonts,control design) as many mentioned here already.

Recompiling for gtk2 didn't fix anything in the first place, because
the options don't match for that!

Here's the solution:

1. Click menu

Deutsch: "Werkzeuge/Lazarus erstellen einrichten ..."
English: "Tools/Rebuild Lazarus ..."  (or similar, i'm not sure cuz
using german)

2. Set all items in list to "Clean+Build" (rightmost icon), except the
following:

CodeTools -> "None"
Package registration -> "None"
Samples -> "None"

3. Select "gtk2" in LCL interface

4. Check "clean all" | "Alles säubern" at top right corner 

5. Check "with packages" | "Mit Packages" below lcl-groupbox

6. Check "restart.." | "Neustart ..." at bottom

7. Click "Create" | "Erstellen" button.

After that, lazarus should restart as a nice gnome/gtk2 application
with correct fonts and colors and design of all controls.

- can you resize a tListBox correctly or not ?
- Can you use the inline help (ex : form1. wait for the procedures and
functions list and select one) ?
- can you use the menu "find/replace" with a replacing word containing
an "a" ?

I get a Fatal error:

/usr/lib/lazarus/ide/main.pp(123,40) Fatal: Can't find unit Laz_XMLCfg

Any ideas???!!! I saw this same problem on this post:

http://www.lazarus.freepascal.org/index.php?name=PNphpBB2&file=viewtop
ic&p=16785

but he is using SUSE, what I use:

fpc 2.0.4
lazarus 0.9.22
ubuntu 7.04

The error disappears if you include the code tools option, but I get a
error while linking. (cannot find -lgdk_pixbuf-2.0) I'll try to
download it later to see if I can get it to work.

That´s a FAQ

http://wiki.lazarus.freepascal.org/Lazarus_Faq#Lazarus_compiles.2C_but
_linking_fails_with:_libgdk-pixbuf_not_found

Every time you get a can´t find -lanything you need to download and
install a package called:

libanything-dev or libanything-devel or something similar

The names change from distribution to distribution, but are similar

Yes I know, but the problem is this: I have the libgdk-pixbuf-dev
package (which supposibly have the library) installed, what I'm
looking right now is that the gdk_pixbuf-2.0 library does not exists
on my system.

I'm trying to make a symbolic link:

/usr/lib # ln -s libgdk_pixbuf.so.2.0.0 gdk_pixbuf-2.0.so

but is not working neither, I do not know if this is the correct name
that lazarus is looking for.

the libgdk_pixbuf.so.2.0.0 isn't the correct library
you must have libgdk_pixbuf-2.0.so.0.xxxx.xx first then symlink it to
libgdk_pixbuf-2.0.so.0 and libgdk_pixbuf-2.0.so

here is all the gtk package you must have :
libgdk-pixbuf2_0.22.0-8.1_i386.deb
libgdk-pixbuf-dev_0.22.0-8.1_i386.deb
libglib1.2_1.2.10-9_i386.deb
libglib1.2-dev_1.2.10-9_i386.deb
libgtk1.2_1.2.10-17_i386.deb
libgtk1.2-common_1.2.10-17_all.deb
libgtk1.2-dev_1.2.10-17_i386.deb
libpng10-0_1.0.18-1_i386.deb

Thanks Wanagen, you where right.

I already have all those packages installed. The problem I am facing
now is with the links to other libraries... so far a need to create
links to libgdk-x11, libgtk-x11, libgobject, libglib, libgthread,
libgmodule, libpango and libatk.

It looks nice but I see some problems with dbgrids and page controls
(tabs and notebook).

I think will keep working with gtk1 and leave gtk2 for a more stable
version.

Thanks again.

I recently switched to gtk2 Lazarus, and it's become generally usable.
It has a lot of quirks tho and I think we need more people to at least
try to use it and report bugs actively. There's more interest for gtk2
from the devs now too. They just need proper bugreports since many of
the gtk2 problems are eg: theme related (I just had one).

But for a stable development I'd still recommend gtk1

Thanks. It works. But there are still some problems with the source
editor. It display character incorrectly. For example:
Code: [Select]
form1.show();

will be display as:
Code: [Select]
form1          .        show   ()    ;

But when you select all text, it will display correctly.
Why? My system is Ubuntu 7.04 with zh_CN.UTF8 locale.
