Hi! Im using HI-TECH PICC Lite COMPILER (Microchip PIC) V8.01 PL3 and the following code gives me some problems. void meep(const char * s) { // Dummy function } void main(void) { meep(" frax was here! "); meep("12345678903434343434"); meep(" frax was here! "); meep("12345678903434343434"); } When I compile with: picl -16f877 -ICD main.c I get: C:\Tmp\_1BK.AAA: 77: undefined symbol u39 (error) C:\Tmp\_1BK.AAA: 84: undefined symbol u49 (error) Exit status = 1 (error) This gives me the same error: void main(void) { meep(" frax was here! "); meep(" frax was here! "); } This works: void main(void) { meep(" frax was here! "); meep("12345678903434343434"); } I couldn't find anything in the manual, did I miss something or is this a bug? tia /frax -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
