Reopening an old file- "C++ does not support default-int"

[d_stranz]

I was wondering if there was some Qt configuration option I messed up

No, the error message says it all: C++ does not support default int. All functions must have their return types declared. There is no return type declared for WriteFile. If this worked at some time in the past, it was probably because the C++ compiler you were using at the time was not compliant to the C++ standard.

This error has noting to do with Qt or your Qt configuration. It's a compile-time error in -your- code.

Okay, yes, nevermind. I messed up my test case because I forgot to include the header file so it never compiled and it gave me the same error when included. I don't know how my compiler difference made a difference when that standard was implemented in 2005. I guess I'll have to go through and add void return types to all my functions. Thanks.

As far as I know, the C language uses "int" as the default return type for functions where a return type is not declared. Since most C++ compilers are written to also compile C, some of them allowed this for C++ methods even though it was not compliant with the standard. I do not know when Microsoft made their compilers compliant with this part of the standard - probably after Stan Lippman joined in 2001.
