"Could not load cFE application" error -- yet .so file exists

[ChristopherRabotin]

cFE refuses to load my custom app. I built it from the sample_app provided, and it compiles correctly. Moreover make realclean && make config && make will create the expected lls_app.so and place them in the expected locations (i.e. build/cpu1/exe/cf/apps/lls_app.so and build/cpu1/exe/lls_app.so). Furthermore, the header of these dynamic libraries confirms that they compiled for the correct target when compared to the other default libraries which load.

Any hint is greatly appreciated as I've been struggling with this issue for several long hours now.

Here's the relevant log:

You may want to also post your startup script and double check the name of the entry function.

X-POST

I'm told by a coworker this error is typical of a runtime error when loading the app. I'll investigate that issue.

[ChristopherRabotin]

That error code does indeed mean the app itself encountered a runtime error.

In my case, I had a typo in one of the functions called from in the *_AppInit initialization function.
