LIBX51 Introduction

The LIBX51 Library Manager allows you to create and maintain library files which may contain one or more object files. Library files may be used by the LX51 Linker to resolve external variable and function references.

The LIBX51 Library Manager may be controlled interactively from the command line, or may be used by µVision IDE. It works with object files generated by the following development tools:

  • Keil A51 Macro Assembler
  • Keil AX51 Macro Assembler
  • Keil C51 C Compiler
  • Keil CX51 C Compiler
  • Intel ASM-51 Assembler
  • Intel PL/M-51 Compiler


  • The LIBX51 Library Manager works with OMF51 object modules and OMF2 object modules.
