It should either work out of the box or you can get a bit version of the MinGW-w64 package. You should be able to run dlltool standalone or at least get an error if something is missing.

The first file is a. This is a text file and can be created by hand, or dlltool can be used to create it using the -z option. In this case dlltool will scan the object files specified on its command line looking for those functions which have been specially marked as being exported and put entries for them in the. This can be done in C by using the asm operator:. The second file needed for DLL creation is an exports file. This file is linked with the object files that make up the body of the DLL and it handles the interface between the DLL and the outside world.

This is a binary file and it can be created by giving the -e option to dlltool when it is creating or reading in a. This file can be created by giving the -l option to dlltool when it is creating or reading in a.

If the -y option is specified, dlltool generates a delay-import library that can be used instead of the normal import library to allow a program to link to the dll only as soon as an imported function is called for the first time. The -S command-line option can be used to specify the path to the assembler that dlltool will use, and the -f option can be used to pass specific flags to that assembler.

The -n can be used to prevent dlltool from deleting these temporary assembler files when it is done, and if -n is specified twice then this will prevent dlltool from deleting the temporary object files it used to build the library.

The linker places this name in the DLL's import library. You assign the function an ordinal value by following the function's name with an at sign and a number.

When you specify ordinal values, they must be in the range 1 through N, where N is the number of functions exported by the DLL. For example, a DLL that contains the code to implement a binary search tree might look like the following:. Add the names of the functions to be exported to this file. Note that the decorated names produced by the compiler are compiler specific.
