Archiver .a and .lib difference

John Mielke

Hi,

I notice that there are two types of library files: .a and .lib.

Both are described in ARM compiler/assembler as libraries.

As libraries are eventually linked by linker, I do not see obvious difference between the two such as between dynamic linked DLL and static LIB. What is the key difference between .a and .lib?

 

Cheers,

    This description applies only to the libraries found in the /lib directory of the TI ARM compiler installation.  That said, the conventions established there are commonly used elsewhere.

    A .lib file is a library of object files.  Such a library is created with the command armar.  That command is described in the chapter titled Archiver Description in the ARM assembly language tools manual.  A .a file is an index library.  It is created with the command armlibinfo.  This command is described in the sub-chapter titled Library Information Archiver Description.

    Thanks and regards,
