Hi! I'm a newbie with using Keil C-51 Compiler! I want to compile a sourcecode and always recive Error 107 unbalanced #if-endif controls! I've looked to all statements and i can not find any mistakes! There is another one! Error 106 unclosed comment! In the compiler discribtion is written: it occurs if there is a '*/' missing, but i don't use comments like this /*--*/ only // comments! because if i am using this /*--*/ type the there is apearring another Error: like this error 141 in line ... near '/' please could anybody help me or give me an advise which is probably wrong! Thanks DANIEL
Well! I am sure that the compiler supports '//' I've changed a couple of things for example i deleted all '*' in the comments and used '//' for '/*-*/' in all files! Moreover i set all #if to #ifdef Now there is no longer the error message #if-endif and unclosed comment! But instead of being free of errors i get about 50 more syntax errors!!! It is really frustrating! Ok! I had to life with the error messages, but i don't understand that the original source is compileable at the newest version, without any problems! Have they changed so many thing? Best regards DANIEL
I am using Keil C51 Compiler Version 3!!!! Have they changed so many thing? Well, we're currently shipping C51 version 7. Version 3 was released sometime around 1991. So, yes, in 13 years I'm sure some things were changed. Jon
Have you looked at the preprocessor listing yet?
When having mismatched #if..#endif problems myself some time ago, I wrote a little PC utility to check them - I'll see if I can find it again... Meanwhile, have you tried GREP?
Well, now have i solved the most errors! It seems to be that the compiler don't like #defines which are calling a other #define for example: #XXX 10 #YYY 1000/XXX I think it causes the most problems. Now there only 4 errors left! I think i could solve them by myself, too. Thanks to all which have replaied! I'll be back!!! :) I am sure with new problems! Best regards DANIEL
