[reSIProcate] Extreme link problem
Hi,
I'm not sure how extreme this is, but I'm ready to grasp at straws, so I
thought I'd see if anybody here has an idea. I already have a SIP app that
uses RogueWave and JThreads/C++ (JTC), a thread class library. Those two
together have a lot of stuff that ordinarily comes from libstdc++, so that
library is not currently linked into the app. I have a wrapper class that
calls the reSIProcate DNS lookup code, and am not using the rest of the
resip stack.
When I add -lresip -lrutil -lares, along with my wrapper, it wont link
unless I add -lstdc++ at the end. Then it links fine but crashes at
runtime. I'll include the stack trace and link line below. The CORBA stuff
is Orbacus but I don't figure that's causing a problem. On looking around,
I see the ~ostrstream destructor comes from the JTC library in the original
link, but now it comes from stdc++. It seems like no matter what I do with
the link order, it always comes from stdc++.
Is there a way to build the resip stuff as a subset or group that is linked
against stdc++, while the rest of the program is linked as before? I
considered building the resip code and libraries into a new .a archive, then
linking that into my program, but I wonder if the stdc++ symbols would still
get pulled in.
Thanks for any ideas you might have,
Dave
