Compiler Error During build when i used file concept (fopen and fprintf) to write into file

[shekharsulgiti]

Hi All,

Need one help.
When I try write to file using fopen / fwrite functions in debug mode I receive like
Error: L6200E: Symbol __stdout multiply defined (by stdio_streams.o and my_lib.a)

not enough information to list the image map
while building the code. and how I can solve it.

You're using Keil, aren't you?

"multiply defined" is their clumsy way of saying that you have multiple definitions of __stdout

As this is specific to Keil - not really to do with STM32 - you'd be better asking them:

(BTW: it's not a Compiler error - it's a Linker error)
