Hi, I've the following problem: I'm using in a program the boost signals library. I compile and link the program with the command below: "g++ -static -o sig.exe -g2 -O0 -I<path to boost include files> -L<path to boost libs> main.cpp -lboost_signals-mgw-d" and I've put the line : "#define BOOST_SIGNALS_STATIC_LINK" in my source code. I'm under the windows platform and I'm using mingw (gcc 3.4.2) and boost 1.33.1 . The program compiles and links without any error but when I try to run it a dialog window says to me that the application has failed to start because "boost_signals-mgw-1_33_1.dll" was not found. It seems that the signal library is not linked statically but I don't succeed in figuring out the reason of this behavior. If I add to the PATH variable the path to the boost libs the program runs properly but I need to get the signal library statically linked, so some help will be very usefull. -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
