I wrote a very simple routine , just call a standard function in c51s.lib ,such as rand(), then transfer it to a lib , then add lib to another project and call the function , but got a link error: fatel error l251: restricted module in library not supported . what's the matter ?
Look on p349 of the Macro Assembler and Utilities for 8051 and Variants User's Guide 07.2000: "251 RESTRICTED MODULE IN LIBRARY NOT SUPPORTED A library contains a module that is created with an evaluation version or a code size limited version. This is not supported."
