7.5.2 Library Information Archiver Example

Consider these object file libraries that all have the same members, but are built with different build options:

Object File Library Name	Build Options
mylib_64plus_be.lib	-mv6400+ --endian=big
mylib_64plus_le.lib	-mv6400+ --endian=little
mylib_6740_le.lib	-mv6740 --endian=little
mylib_6600_be.lib	-mv6600 --endian=big

Using the library information archiver, you can create an index library called mylib.lib from the above libraries:

libinfo6x -o mylib.lib mylib_6600_be.lib mylib_6600_le.lib

You can now specify mylib.lib as a library for the linker of an application. The linker uses the index library to choose the appropriate version of the library to use. If the --issue_remarks option is specified before the --run_linker option, the linker reports which library was chosen.

Example 1 (ISA 64plus, little endian):

   cl6x -mv64plus --endian=little --issue_remarks main.c -z -l lnk.cmd ./mylib.lib
   <Linking>
   remark: linking in "mylib_64plus_le.lib" in place of "mylib.lib"

Example 2 (ISA 6600, big endian):

   cl6x -mv6600 --endian=big --issue_remarks main.c -z -l lnk.cmd ./mylib.lib
   <Linking>
   remark: linking in "mylib_6600_be.lib" in place of "mylib.lib"
