..while I'm in the complaints department:

Don't know if it's a bug or not, but if I create a .cpp-file in
a package with the same name as the package, then after a small
number of edit's and compile's, theide crashes and then refuses to
load the package when I select it at start-up giving the above error-message.

I get it to reload the package only if I rename the package &
.upp-file OR the .cpp-file to something else.

Could be something that needs attention.

Hello slashupp

Could you upload a sample package just "ready to crash"?

What system are you using?: Windows, Linux.

Best regards
Iñaki

I'm using upp nightly 6840 on debian wheezy/sid.

I'll try to create such a package...(at moment am fire-fighting)

Another couple of things:

Irregularly (difficult to isolate) I get a segmentation-fault
when editing a layout; I restart theide again & all is OK - for
now I just live with it.

Had a strange case getting a theide seg-fault when loading my
package where in my source-code I called at(0) on an empty
std::string - changed my source (debugging uppsrc/ide-package in
theide itself) to check that the string is not empty and theide
then loaded my package:
Changed: if (s.at(0)!='#') { ... }
to: if (s.length() && (s.at(0)!='#')) {...}
(strange one this)

REALLY REALLY NEED a working debian package for theide
especially a NOGTK version - I failed to create a stable NOGTK
compile using input from another thread and is currently using
the standard make / make install version from 6840

(I'm using theide to develop UI's for my own apps that has some
urgency; I would have liked to but cannot really afford the time
at the moment to assist in full debugging of theide - will do so
once the urgent stuff is done)

Praise & thanks where it is deserved:
theide makes building GUI's really easy and straight-forward
and I like the intuitive-ness of it - thanks to all you devs

Try this.

if (s.length()) {
 if (s.at(0)!='#')) {...}
}



Warm Regards

Hello slashupp,

You can use my script to compile Ultimate++ in X11 mode.

1. Copy all files included by me in this message to upp directory.
2. Execute following commands:
chmod +x compile.sh
./compile.sh

3. Enjoy X11 IDE!

P.S.
Use at your own risk! (First, please check what script do).

Sincerely,
Klugier

Hi deep
You're right with that, but you miss the point:
The entire theide crashes when it is loading my application's
source (which contains that line) - THIS SHOULD NOT HAPPEN!
I should be able to write any kind of junk in my source files
and fully expect theide to load them without complaint.

I've managed to narrow-down somewhat to a possible cause for
theide crashing: it seems to have something to do with the
<UUID?>.cache-files and/or "MyPkgName@MyWorkDir.cfg" that theide
creates in ~/.upp/theide/cfg

If I delete "MyPkgName@MyWorkDir.cfg" theide loads the package
most-times without crashing with the above error, other times I
need to delete all the <UUID?>.cache-files as well

What I do now before I open a project is to delete both the above
sets of files from ~/.upp/theide/cfg

What are these files for anyway? Are they really needed?
For me they cause more harm, hassle and frustration than any
perceivable benefit whatsoever.

So, what do you recomend insted of bash?

You should put it in "extracted sources" directory. Exactly the same place where you are typing "make" command.

@klugier:

Done as you said with the scripts:

copied the new theide to my ~/bin (it is in my PATH)
and ran it ...

1. doesn't do setup

I manually copied bazaar, ..., uppsrc, to ~/upp
ran theide again:

2. no build methods

found GCC.bm and imported it

Tried to compile Addressbook example: failed because it could
not find a load of headers from "/usr/include/gtk-2.0/..."
Why is looking for gtk-stuff?

3. not "Enjoy X11 IDE!" yet

any suggestions?

It seems that you compile "x11 ide" successfully.

Does IDE detect all necessary ultimate++ packages like CtrlLib, CtrlCore etc?

Quote:

Did you copy GCC.bm.in also?

Quote:

It is only the path for gtk headers. Remember that even if you have X11 IDE the executable is still compiling in full GTK mode. If you want to fully remove GTK from your project try following compilation flags:
X11 - Deletes GTK backend, but GTK theme can still be used. (GTK libraries are linked to yours executable file).
NOGTK - Fully remove gtk, no GTK theme. (GTK libraries are NOT linked to yours executable file).

TheIDE only does setup when it detects ~/.upp doesn't exist. You can run it explicitly from theide itself, it is accessible from Setup -> Source management...

I've copied mkfile and compile.sh into extracted source dir.
I ran ./compile in extracted source dir - it compiled
I deleted existing ~/.upp and ~/upp dirs.
I copied theide into path-dir.
I ran theide and I got what looks like X11 windows, it did not do setup; build methods are empty.
I copied bazaar, ..., uppsrc to ~/upp
I created build method GCC, and selected builder GCC.
I create a new package (helloworld-style) and specify 'GUI SSE2 NOGTK'.
Tried to do 'GCC Debug'-build and got:
----- CtrlLib ( GUI SSE2 NOGTK GCC DEBUG LINUX POSIX ) (1 / 9)
ChGtk.cpp
In file included from /home/slash/upp/uppsrc/CtrlLib/ChGtk.cpp:2:0:
/home/slash/upp/uppsrc/CtrlLib/ChGtk.h:9:21: fatal error: gtk/gtk.h: No such file or directory
 #include <gtk/gtk.h>
                     ^
compilation terminated.
CtrlLib: 1 file(s) built in (0:00.70), 701 msecs / file, duration = 713 msecs, parallelization 0%

There were errors. (0:00.71)


Can I ever become rid of gtk?

What version of U++ sources do you have? This seems a lot like problem that was solved in revision 6698...

ah! now I'm starting to get the picture ...
The reason I need get rid of GTK is that I have build (B)LFS with minimal extras, only X11 with openbox for window management
Ok, that brings more sense into what you're trying to do Wink

Quote:

Can I add these flags to 'make -C uppsrc' in the domake script?
Unfortunately, some things are pretty hard-coded in the makefile Sad I would recommend you to rather use the universal makefile. Just download the file, put it in the directory with unpacked sources and run this:
make -f mkfile PKG=ide NESTS=uppsrc LDFLAGS="-Wl,--gc-sections -Wl,-O,2" TIME= COLOR=0 USEMAINCFG=0 FLAGS="GUI NOGTK GCC" TARGET=$(pwd)/theide JOBS=5

This should build theide without GTK. You can also use this for any other U++ package, just by tweaking the parameters a bit. Detailed documentation is inside the makefile.

Honza
