Application runs fine from the IDE but when run from the exe, the app crashes

Sometimes errors are subtle. Are you using absolute file names to locate the config file(s) or are you doing something trying to figure out the proper location from argv[0]?

[QIII]

Depends on what it will be running on.

It still really sounds to me that something is causing the code to run out of bounds of an array. Do you have a test harness built so that you can vary inputs and test boundary conditions and such?

What was your testing methodology? Did you "see if it works" or "try to break it"?

Edit -- lisati caught something I missed and I had to read back through the thread. Depending on where and how to are catching exceptions, that error may be a red herring. Make sure you have the path right. If it is not running on ANY other machine, that may be it.

I have absolute file names but here is an interesting part..on some machines I have to have the complete filename with extension such as MyParameters.txt. The Window pops up from the exe. on other machines, I have had to cut out the extension .txt to have the exe pop up window, otherwise there is no response.

Apologies for a duplicate reply. My path is the folder I am running the exe from.

[QIII]

So, is that behavior consistent between OSes?

I.e.: On Ubuntu you have to have it one way and Fedora the other?


(BTW: Are you checking for the existence of the file before you try to read from it and handling a "file not found" exception gracefully?)

[nasdaqtr]

I have only used Ubuntu..that is the target OS.

[QIII]

In general, C++ doesn't give a hoot about file extensions. It should be able to find foo as easily as bar.txt. Of course foo is not the same ast foo.txt.

I don't believe I have ever run across something like this.
