Code::Blocks Fortran DLL Primer Tutorial<\/p><\/div>\n

The tutorial today is about a programming IDE called Code::Blocks, and we use this to create a project in which a Fortran Windows 32bit application calls a Fortran DLL<\/a> doing some simple work with a two-dimensional array (and saying hello<\/a> … bienvenuto … selamat pagi … g’day).<\/p>\n

Programming IDE<\/a>s take a lot of the hard work out of tasks such as compiling and linking in languages such as D, Matlab, Fortran (Code::Blocks) or Java, C, C++, VB.Net and C# (NetBeans) … and please know that there are many other languages and many other IDEs. In the case of Code::Blocks IDE, which this blog reintroduces to you today (it’s customary to shake hands, and no Klingon<\/a> is necessary), it can create a C++ Win32 GUI project environment. To cut a long story short, there aint nothin’ wrong with a good ol’ IDE, but beware of IDEs in March<\/a>.<\/p>\n

In saying that about IDEs, and how they make programming easier, often with Open Source programming, it is advantageous to know what goes on “under the hood” (or even “in the ‘hood” … chortle, chortle). So if you ever get an opportunity to get helped creating your own makefile (or make it yourself, even with the Sweet Green Icing<\/a> … knew it could be worked in!) for something, take the opportunity to learn how to do this, as the Open Source world will become a little easier to navigate with such types of knowledge. You’ve got to admire those early designers of computer languages, and those days when all you had was this tiny bit of memory (64k<\/a> or “into the heliosphere on 8,000 bytes of memory”<\/a>) to play with to create your program. <\/p>\n

In today’s tutorial<\/a> we write a simple Fortran Windows 32bit application that calls a DLL. <\/p>\n
