Hello John,
In the test above, a valid definition for UINT32 was found.
The proper header file is getting included. The error message
is because Microsoft Visual Studio 2010 does not fully support
the C99 language standard. Your code is using the C99 feature,
"mixed declarations and code".
Microsoft support for the C99 language standard is work in
progress. While no Microsoft compiler fully supports C99,
Visual Studio 2013 does support mixed declarations and code.
Two solutions are possible: 1) Switch to Microsoft Visual
Studio 2013. 2) Avoid use of "mixed declarations and code".
For example:
// fails with VS2010
UINT32 test1 (UINT32 a)
{
a++;
UINT32 b = 1;
return a + b;
}
// passes with VS2010
UINT32 test2 (UINT32 a)
{
UINT32 b = 1;
a++;
return a + b;
}
Thanks,
Scott
