Re: [DynInst_API:] undefined reference to `dlopen' error during parseThat build

[Andrew Bernat <bernat@xxxxxxxxxxx>]

We have been fighting with that for a long time, and I had thought we had it fixed. Apparently not. 

Can you manually copy that compile line and add -ldl to the end, after -ldwarf? I'll go figure out why it's not there to start with.

Hi devs,

I was trying out dyninst 8 on 32-bit Ubuntu 12.04 and hit the following compile error doing 'make DyninstAPI'.

I noticed that the '-ldl' library is specified, so I'm not sure what's going on. Any ideas?
