RE: [Boost-users] Trouble linking regex library on Solaris machine

Howdy. As I am only interested in using the regex library right now, I followed the instructions for building that library only, using dmake. Compilation went fine. When I tried using the library in a little test program with the command:

g++ regextest.cxx -I./boost_1_31_0 -L./boost_1_31_0/libs/regex/build/sunpro -lboost_regex -o regextest.cxx

I get many undefined symbol errors. If requested, I can provide the entire error output.

It looks like you are trying to use the wrong library. SunPro refers to the Sun C++ compiler and tools whereas you are using GNU C++. You have to build the library and application with the same compiler.
