TD-18475: TD freezes at step 'Compiling ext. functs...'

[drasmussen]

Please see the attached Repro-/Test-Case, which shows a current problem with implementing and compiling an interface to some functions of an certain external dll.
This problem does occur in TD41 and also in other major releases of the TD.

I don't understand, what is going wrong at this constellation?

Any help is appreciated!
Thanks in advance!

Yes, you will need to zip and attach desko_ipl.dll by itself. PageScanAPI.dll imports it.

The DLL will be even in zipped mode too large for the uploader of your forum.

I don't either. I got your zip with all files and see that TD hangs at the step you mention. I checked DLLs, and they open OK with PE Explorer. Only thing I have not seen is where one ext. DLL requires another ext. DLL. That *may* be the problem.
(Well, many DLLs require other Windows DLLs, for example. I guess I meant a 3rd-party DLL requiring a non-Win. 3rd-party DLL and getting a prompt when it wasn't there. That is the first time I have seen this.)

All I can do is submit this as a TD defect, Dirk, which I will do and update this msg. with the TD numbeR: TD-18475

Hi Jeff,
many thanks for your effort!

BTW:
I've already verified, wether these DLLs require some other ext. DLL, by compiling my TestCase directly in the directory of the DESKO-Demo/Sample-Application (DESKO-SDK ...), where indeed some other DLL-files exists. But no change -- TD still hangs while compiling the external function section.

Hello,

I guess that you don't have the sources of the DLLs.
Maybe there are some debugging options that you can set in a DLL related configuration file!?
Because when TD compiles the external functions, it has to load the DLLs which in turn causes the DLL-initialization function DllMain to be executed.
If the DLL does heavy stuff in there, it may cause a hang.
But if you could enable some kind of logging for the DLL, you may get some mor information!

Hi Max,

thanks for your hint.

And you are right, I don't have sources of the DLLs. ...
But in parallel, I have posted this issue to the developer/manufacturer of these DLLs.
