[fpc-pascal] Linking object file

[md at rpzdesign.com]

Darius:

I just went through this and it is fresh in my mind, but with 32 bit code.

I used CodeBlocks with MingGW to compile the c source code to a static 
library with an mylib.A suffix.

I am pretty sure you cannot use MSVC to compile the c code.

Then use the {$LINKLIB path/mylib.a} directive to link.

You do not need to use individual object files since many times there 
are many that are combined into a single static library.

When you use codeblocks, you will need to make an adjustment to produce 
64 bit binary.

It is just easier to stay with 32 bit if you can.

Let us know how it turns out in 64 bit {$LINKLIB xxxx}

Cheers,

md
