Question

I’ve recently written a C program which uses the public-domain mpir and mpfr libraries. I’ve been compiling it on Windows, using the Microsoft Visual C++ 10.0 compiler. To get that to work, I had to do the following:

• Download / build the mpir and mpfr libraries from http://gladman.plushost.co.uk/oldsite/computing/gmp4win.php
• Move the files mpir.h and mpfr.h into the Include directory for the Microsoft compiler
• Move the files mpir.lib, mpir.pdb, mpfr.lib and mpfr.pdb into the lib directory for the Microsoft compiler
• #include mpir.h and mpfr.h in the program
• Compile using cl <..module names..> /link mpir.lib mpfr.lib

I now want to send the source / header files I’ve written to someone else, along with a makefile that they can use to compile the code and check that it works. Since that person won’t have the mpir / mpfr libraries installed, and might not be using the same compiler, I’m not quite sure how to do this.

Here is what I can do:

• Send them the binaries mpir.lib, mpir.pdb, mpfr.lib and mpfr.pdb as well as the source / header files.

Here is what I can’t do:

• Send them my entire Microsoft Visual C++ 10.0 setup
• Ask them to stick files in their Include and lib directories (unless there’s no other way)

Ideally, I should be able to send them the source/header files, together with the pertinent mpir/mpfr binaries, and a makefile which they can then run to build the program.

Thanks in advance for your help!

Answer 1

Why on earth are you adding those files to your compiler installation path?? The compiler has command line options for specifying search paths.

For instance,

cl /I"path/to/mpfr/header" <...filenames...> /link /LIBPATH:"path/to/mpfr/lib" mpir.lib mpfr.lib

You should only have to send your source code, mpir.h, mpir.lib, mpfr.h and mpfr.lib. The PDB files contain debugging information, and are not necessary for compilation.

Also, I don’t know how to create a makefile, but a simple batch file with the command above should suffice for something so simple.
