I built the library individually with the following line :

everything seems to compile properly but when I use the following from a

.so

:

boost::regex exp("std");

I get the following error from dlopen:

ld.so.1: output/Text2RvMsg_tester: fatal: relocation error: file
output/Text2RvMsg.so: symbol

__Q25boostt14reg_expression3ZcZQ25boostt12regex_traits1ZcZQ24_STLt9allocator
1ZcPCcUiRCQ24_STLt9allocator1Zc:

referenced symbol not found

does anyone know how to get around this?  There are similar symbols within
the debug.so that I am trying to use however they are usually a
regex_traits1ZcZt24 or something similar.

I have tried to search for this but can't find a match for it, is it some
gcc compilation error?

No idea we could use some input from a gcc expert to tell us what that
symbol means, just an idea here, but can you not link against the .a lib
file - apart from anything else your final code size will be much smaller
(including the size of the lib that is).

To de-mange gcc symbols, run the command c++filt <mangled symbol>. The symbol mentioned above is:

boost::reg_expression<char, boost::regex_traits<char>, _STL::allocator<char> >::reg_expression(char const *, unsigned int, _STL::allocator<char> const &)
