[Dev-C++] .cpp to .lib or .a

[<age...@co...>]

I have been wanting to write my own library of classes that perform OpenGL 
functions in order to reuse code effectivley. I was thinking about adding the 
declerations in a .h file, and writing the actual definitions in a .cpp file, 
which i would convert to a .lib file. Dev-C++ uses .a, so would I just run the 
project static library to make the .a file, or is there a command line utility 
which takes a .cpp file and makes it into a .a file? Thank you for replies in 
advance.

For what I know about it the .a format is the same than the .lib for 
MSVisual C++ (coff), so you shall only need a rename of the .a file to 
.lib; if you want use it for Borland, which uses OMF format, you need 
run coff2omf.exe, which is in the binary folder of Borland.
If that doesn't work, then it seems you'll need use reimp, if you need 
it (I don't think so), email me and I'll send it to you, it's small and 
it seems not very easy to find.

Hope it works.

There IS a command line utility which creates archives, or libraries and 
it comes with Dev-C++ (MinGW). It is called "ar" (archiver). Actually, 
Dev-C++ uses this. It can create archives from object files. You first 
need to compile all sources to object files.
Type "ar --help" to get a list of comand line options. The most common 
options are "ar cru <libxxx.a> *.o"
In "*.o" * is a wildcard, so ar will get all .o object files and create 
the archive.

A quick'n'dirty way to create an archive (library) of all sources (.cpp 
and .c) in the current dir, type these 2 commands:

g++ -c *.cpp *.c        - (compile all .cpp and .c files to objects)
ar cru libxxx.a *.o     - (create the archive)
