Question

For some reason when I try to run b2 with toolset=gcc I get the following.

C:\boost_1_49_0>.\b2.exe toolset=gcc
C:/boost_1_49_0/tools/build/v2/tools\gcc.jam:129: in gcc.init from module gcc
error: toolset gcc initialization:
error: no command provided, default command 'g++' not found

What am I doing wrong?

Edit: I had to add C:\MinGW\bin to my Path environment variable.

You should run this command in a command line which can access mingw/cygwin bin directory. I mean when you type g++ it works and doesn’t return command not found. If you are using mingw or cygwin they have dedicated command lines which g++ (bin directory) paths are registered in environment variables. Of course you can use Eclipse for compiling your c++ apps under windows.
