Hi Graham,
Indeed, I've found that building a C++ program adds several
layers of complexity compared to dynamic or .NET languages! One has to
deal with directories for include, library, and resource files, various
other compile and link options, etc. When the IDE is configured right, it
can make things convenient, but configuring it for a new application
framework can be challenging. It also has the disadvantage of hiding much
of the complexity that is often necessary to understand for systematic
debugging. Make files, although plain text, are hard to follow. I
still prefer a linear batch file whenever possible.
