[gobo-eiffel-develop] EDP -- The Eiffel Developer's Project

[Howard T. <how...@di...>]

Hi all,

I have made a download available of the current state of my Eiffel IDE 
project, as a tar.bz2 archive of the source code of my development tree.

I have also provided executables for Linux and Windows, both 32-bit.

The 64-bit executable for Linux now works when compiled by edp+gcc, and the 
32-bit Linux code can also be compiled by EiffelStudio, or at least I have 
successfully done so once.

It is very much alpha status, and is certainly not yet a replacement for 
anything else, although I am starting to find it useful in it's code-browsing 
usage, with feedback about which classes within a class universe are part of 
the current system.

The WIN32 version compiles and links, albeit not yet using geant for the 
complete process. Although the SmartEiffel compiled version ran, I have made 
some major API changes since then between the Eiffel code and the supporting 
WIN32 glue code, so the current code may not.

When renamed as 'gec', the edp executable performs as 'gec' and is the version 
of 'gec' that I use to generate both Linux and Win32 C files for further 
processing. I may well need to provide a bootstrap process to simplify 
startup for working with the EDP project code.

The supplied directories 'edp' and 'tool' are intended to be located as 
subdirectories of $GOBO, with 'tool' provided primarily to show that some of 
the entries are symlinks into 'edp/tool/' and 'edp/library' containing 
modified classes needed for the adapted 'gec' functionality.

Note that the Eiffel code links directly with libX11 and libgdi32 and is 
therefore independent of any C/C++ GUI code on either platform, and that was 
one of my primary aims when starting out on this project.

The (minimal !) website is at http://ashford-ht.vm.bytemark.co.uk

Comments and criticism welcome ...

Regards,

Howard Thomson

I just tried the Linux executable, and I get:

Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Exception no 11
Printing ge_stack ...
gestack_ptr = bf9d4184
   Current->id = 78
gestack_ptr = bf9d41cc
   Current->id = 78
gestack_ptr = bf9d420c
   Current->id = 21
gestack_ptr = bf9d425c
   Current->id = 21
gestack_ptr = bf9d42b4
   Current->id = 21
gestack_ptr = bf9d42e8
   Current->id = 21

The DISPLAY environment variable is set to :1.0 here - looks like it is
ignoring it for some reason.

Hi Colin,

Yes, that is a deficiency, which I will be fixing in the near future ...

How i love the smarteiffel stack traces - one reason to never purchase

Hi Lothar,

You don't say whether you tried the Linux version or the Win32 version ?

The Win32 version uses a lot more C glue code, and the Gobo tools need some 
persuading (i.e. kludges) to establish the correct type-set returned from an 
external "C" call. I have also made some changes to the interface between 
Eiffel and C since it (the Win32 version) was last working ...

I have'nt had a crash on the Linux version for quite a while (months).

Regards,

Howard

Hi Lothar,

As I thought, the Gobo tools compilation results in a call to gevoid() from 
the callback from the C glue code, whereas the previously functional 
compilation was by SmartEiffel which does not do such an analysis.

I have made available a new executable with that bug fixed ...

Howard

I downloaded edp.exe again and I still get a call-on-void-target.
