I'm trying to print functions name with __func__ macro in a 8051 project.
But when I build on Keil, It has an error like this:
main.c(50): error C202: '__func__': undefined identifier
have any macro others similary? Please help me solves it.
As the documentation says, the Keil C51 compiler does not support this macro, and apparently no other of similar functionality:
The Cx51 Compiler provides the following predefined constants you may use in preprocessor directives and C code to create portable programs.
Constant Description __C51__Version number of the compiler (for example, 701 for version 7.01). __CX51__Version number of the compiler (for example, 701 for version 7.01). __DATE__Date when the compilation was started in ANSI format (month dd yyyy). __DATE2__Date when the compilation was started in short form (mm/dd/yy). __FILE__Name of the file being compiled. __LINE__Current line number in the file being compiled. __MODEL__Memory model selected:
0 for SMALL,
1 for COMPACT,
2 for LARGE.__TIME__Time when the compilation was started. (Format: hh:mm:ss) __STDC__Defined to 1 to indicate full conformance with the ANSI C Standard.
