#843 Error in building file?(not c code troubleshooting)

[tan zheng boon]

hi. why does my compiler keep refering to math.h even though i didnt #include it in and even deleted it?
it just shows 50+ build errors

include <stdio.h></stdio.h>

void main (void)
{//main start

printf("Hello World");
}//main end
is what i tried to compile, this was the build error log

this is completely invalid syntax :
include <stdio.h></stdio.h>

C/C++ is not html. I would suggest you read a book on C/C++ first ;-)

[tan zheng boon]

oh, the paste was not text only. my code was
(#)include <stdio.h>
void main (void)
{//main start</stdio.h>

printf("Hello World");
}//main end
idk why the pound isnt showing

Next time use the code tag (fourth icon above when editing) so your code is not interpreted as formatting tags by the editor.

[Lieven de Cock]

ensure you have setup you compiler corectly, C/C++ headers can include others, so well possible that stdio is including math for example. It seems to point then in the direciton that your compiler, or include paths are not setup correctly ?

[Miguel Gimenez]

This is not the place to discuss this, if you think it is a C::B problem then post a full rebuild log in the forum.

oh my bad, thank you for all your advice

Broken compiler, closing as invalid...
