I had similar problem when I first ported my code to polyorb. Are the
files displaydata.adb, tradesdk.adb, tradesdk-flexsdk.adb compiled
before in another step of your compilation script ?

What I'm used to do is to separate the annex E code from non Annex E
code. The non Annex E code can be compiled as a library and the DSA code
have to be compiled only once at the gnatdist time.

I hope it will help, please feel free to ask questions/ping me/...
