[OpendTect_Developers] Regarding DTECT_APPL env. variable

[John Watson]

Hi Vaqar
 
Are you developing on Windows using Visual Studio? I find I get the
"missing icons" problem when I run OpendTect on windows but without the
correct working directory. In OpendTect code file Basic/oddirs.c the
function GetSoftwareDir() uses _getcwd() to work out where the software
is installed and hence where to find the toolbar icons. This means in
order to launch opendtect correctly on windows, you must either open a
cmd window, cd to the bin/win64 where od_main.exe resides and run
od_main from there, or you can setup a windows shortcut which has the
"Start in" property correctly set.
 
Maybe a minor change to GetSoftwareDir() would also help: if it were to
use the more Windowsy function GetModuleFileName(), this would return
the location of od_main.exe regardles of the working directory. It would
then be possible to run OpendTect correctly from the windows Start menu
"Run" option for instance.
 
Cheers
 
John

Subject: [OpendTect_Developers] Regarding DTECT_APPL env. variable


Dear All,
I am working over the compilation of OD's 4.2.0. The compilation process
was successful so far but the application does not have the necessary
graphical item like e.g. icons don't show up. Now I tried few other ways
to fix this but it seems like the problem of
DTECT_APPL=%WORK%\OpendTect-4.2.0
Here the OpenDtect 4.2.0 application resides in the work folder.
Application compiles and runs successfully (as mentioned above) if I
dont set this variable but in case I have this variable set, I come
across the following error

"Unhandled exception at 0x09b906a2 in od_main.exe: 0xC0000005: Access
violation writing location 0x0110156c."

I am cluesless as I cant catch it via debugging since it keeps on
occuring on different locations in the source code. 
Any suggestions!
Thanks in anticipation
