Hello together,
I'm coding a simple UART-Application on the MCBSTM32 eval board and have problems with the preprocessor directives. I studied the whole documentation here and I'm pretty sure I'm coding in a common way, but still I can't compile my program. These are the very first lines of my main header file:
#ifndef ___MAIN_H_ #define ___MAIN_H_ #endif #undef EX #ifndef ___MAIN_C_ #define EX extern #else #define EX #endif
And my variables a coded that way:
EX unsigned int ui_TxFrameCounter;
When compiling the program, I get the error code "L6200E: symbol multiply defined" for my variables, because of including the header to other files. I want to declare the variables "extern" for the other header files. Could somebody help me? Would be nice. Geetings
I assumed that he had something inserted there, but now removed for brevity.
Anyway - most source code editors don't look for keywords in preprcessor lines - as soon as they see #define they color the full line using the "preprocessor" color. Same thing with comments - try to write keywords inside comments, and you still get the markup for a comment.
