Visual 2010 compilation errors
in [MFC]
|
From: DamL on 8 Jun 2010 09:05 Hi, I have solutions that compile under VS2008 with no warning nor errors. While porting them to VS2010 I've got this kind of behavior : C:\Program Files\Microsoft Visual Studio 10.0\VC\atlmfc\include\afx.h(469): error C2146: syntax error : missing ';' before identifier 'AfxCrtErrorCheck' etc., all related to VS2010 own files and mainly related to types definitions. Our solutions are using mfc. What's wrong with VS2010 while compiling ?

Probably nothing wrong there. :-) The symbol immediately before 'AfxCrtErrorCheck' is errno_t. You don't have a macro redefining that, do you? Or some unusual way of including the header files?

The text is: inline errno_t AfxCrtErrorCheck(errno_t error) which tells you immediately that the word errno_t is not defined, and therefore is not known to be a type, resulting in a syntax error. You did not tell us where the #include <afx.h> occurs, or what precedes it, or what follows it. The afx.h file includes <errno.h> up towards its front. This can suggest that perhaps you are getting the wrong file, perhaps from some older library header set. A technique that can be used to determine exactly what happened is to use the /P compilation option (there's a property, and I'm not sure where it is in 2010, that sets this, or you can hand-edit this option into the command line for the file that is producing the problem; note that this is case-sensitive, and must be /P, not /p) The result is a .i file in the source directory, which is the expanded text from the preprocessor. Now locate the above line that defines AfxCrtErrorCheck. See what it says (note: the file will be huge, hundreds of thousands of lines). If it says errno_t, then search backwards from this line looking for typedef int errno_t which should be in the file crtdefs.h. If you don't find it, that's what is wrong. Go look to see where crtdefs.h is included (it is included by errno.h). You should see the whole path displayed. It sounds like, just at a first guess, you have messed up your search paths and are getting some incorrect file, so the symbol errno_t is not being properly defined. But as to why this is, without having the ability to poke around on your running version of VS2010, there's no easy way to find it from where I sit. But you can look. joe **** > >etc., all related to VS2010 own files and mainly related to types >definitions. > >Our solutions are using mfc. > >What's wrong with VS2010 while compiling ? > Joseph M.

From: DamL on 9 Jun 2010 09:39 Hi, problem is now solved : I've reincluded the root VS2010 inc/lib and same for VS2010 atlmfc inc/lib directories into "VC++ directories" option of project itself and it now compiles and links. Execution is also correct.
