[srslte-users] Problem compiling own srsLTE-based program

[Vasil Velichkov]

Hi Johannes,

It does not find the main function because it does not compile the .c file.

And it does not compiles it because you need to specify it.  Try with

     $(CC) $(WARN) $(CFLAGS) $(INCLUDES) -o pdsch_listener pdsch_listener.c

Vasil
