IntelliSense error with __null

[Dan]

Hi, I am currently testing VisualGDB for the company I’m working for in order to program a STM32F4xx micro-controller on a PCB we designed. I could’ve gone with Atollic TrueSTUDIO or IAR embedded workbench, but I am really dependant on the IntelliSense plus we’ve been coding the rest of the application on Visual Studio 2010, so VisualGDB with the GNU toolchain was an obvious easy transition for me.

The problem is that I am developping the software in ANSI C and I suspect that some compiler definitions (preprocessing definitions) are missing. When I include or or (well anything that uses ) and that I want to use the NULL definition, I get an IntelliSense error that __null is undefined because these lines in :

#if defined (_STDDEF_H) || defined (__need_NULL)
#undef NULL /* in case has defined it. */
#ifdef __GNUG__
#define NULL __null
#else /* G++ */
#ifndef __cplusplus
#define NULL ((void *)0)
#else /* C++ */
#define NULL 0
#endif /* C++ */
#endif /* G++ */
#endif /* NULL not defined and or need NULL. */
#undef __need_NULL

Looked everywhere for the __null definition and couldn’ find it. I suppose it is a reserved word for GNUC. What should I do to remove that intelliSense error ?

Also, I seem to be unable to compile a single file without having to re-compile the whole project which I believe is absurd. Is there a way to go around that ?

Hi,

You can add a definition of __null for IntelliSense in the gcc_compat.h file located in the VisualGDB installation directory.

Normally make should compile only the changed files when compiling the project. If you are changing files included in many other files, then of course those files too need to be recompiled.

Great added to gcc_compat.h
#define __null 0
and I get no IntelliSense error, sweet thx.

Indeed the makefile only recompiles the changed files, but what I meant is the “Build->Compile (Ctrl-F7)” from the Visual Studio main menu as well as the mouse’s context menu (right-click) “Compile (Ctrl-F7)” are grayed out. The shortcut is also disabled. This kinda sucks when you want to verify the compile success of only 1 source file when you’re modifying a bunch files altogether while merging projects and have to go through a makefile that will compile all the modified sources that you know will most probably cause compile errors and add useless compile time. So, is there a way to go around that missing feature ?

[ket]

Hi,

We currently do not support compiling single files. We are considering adding support for it, but as it is a complicated feature to support for some of the project types, we may add support for it gradually.

As a workaround you could disable makefile auto-updating of SOURCEFILES temporarily (remove the #VisualGDB: AutoSourceFiles line from the Makefile) and use the Makefile to compile only the files you add to SOURCEFILES.

[Dan]

Ok great. Keep me informed when that feature is added, can’t wait to test it.

Great tool, keep it up and thx for everything 🙂

Hi,

Are you looking into kernel sources? What libraries and includes are you using i.e. how could we reproduce the same errors on our side?

[Lonko]

Oh found where the problem exists, until i have cdefs.h file open i have all those errros.

But why i went to the file in the first place is because of the anoying
/* The GNU libc does not support any K&R compilers or the traditional mode
of ISO C compilers anymore. Check for some of the combinations not
anymore supported. */
#if defined __GNUC__ && !defined __STDC__
# error “You need a ISO C conforming compiler to use the glibc headers”
#endif

and it is because __STDC__ is not defined. is this normal?
Can i define it?

Regards,

[support]

This is strange. __STDC__ should be defined in a gcc_Debug.h file in your project directory and this file should be added to ‘forced includes’ in Visual Studio project properties. Could you please recheck whether the file contains the __STDC__ and whether it’s parsed by IntelliSense?

[Lonko]

in gcc_Debug.h is only #define __STDC_HOSTED__ 1

and no __STDC__ and intellisense does not parse it.
What is more strange is that intellisense does not find some of the header files that are in the local cache.
For example it cannot find #include “svc_uif.h” but compilation goes ok. The file is located in C:UsersUporabnikAppDataLocalVisualGDBRemoteSourceCache192.168.3.207005includesvc_uif.h but for some reason intellisense does not pick up the file!

also in gcc_Debug.h
// — Include directories begin — //
//all includes are commented so no includes listed here!

Also it nags about redefinition of DEBUG

This is the whole gcc_Debug.h
/*
This file is only used by IntelliSense (VisualStudio code suggestion system)
DO NOT INCLUDE THIS FILE FROM YOUR ACTUAL SOURCE FILES.
This file lists the preprocessor macros extracted from your GCC.
It is needed for IntelliSense to parse other header files correctly.

The compilation and IntelliSense use two independent source parsing mechanisms, so it could happen that IntelliSense shows false positive errors when its mechanism runs out of sync with the build mechanism.
Regarding svc_uif.h file, is C:UsersUporabnikAppDataLocalVisualGDBRemoteSourceCache192.168.3.207005include referenced in Include Search Path (Visual Studio Project Properties -> NMake -> Include Search Path)?

If __STDC__ is not present in the .h file, this can be happening because GCC does not report it when being tested with your configuration settings. This can be specific to your GCC version or some settings. The easiest workaround would be to create a new file (e.g. called gccfix.h), add it to ‘forced includes’ in Visual Studio Project Properties -> NMake and add the following code to it:

#ifdef _MSC_VER
#define __STDC__
#endif

This should provide IntelliSense with the missing definitions. _MSC_VER is a macro that is defined by Microsoft Compiler (and Microsoft IntelliSense engine) and won’t be present during build with GCC.

[Lonko]

You are correct the cached include folder was not in the NMAKE options!
Now the errors are gone but somehow intellisense sometimes show limits and all the errors in it but that will be survivable 😀

Thank you!
