@ccall for adslib.so

General Usage
1

Hello,
I sucessfully used the TcAdsDll under windows which is used to communicate with beckhoff hardware. Now I m switching stuff to linux and want to use the library here which produces adslib.so TcAdsDll. Julia can load the library but any function I try to call reports undefined symbol. What should I do ?

If julia errors out because the symbol you’re trying to ccall it means that either you’re using the wrong name, or that the symbol is not visible. Check with

nm -D /path/to/adslib.so | grep '<symbol name>'

to find the function name and its visibility status.

Thanks, that’s effectively the problem; this lib version does export only a part of the functions !
