header files cannot be opened

[rkambika]

hi,

I am developing an s60 application(s60 3rd edition) in carbide.express using c++. I have installed the s60 3rd edition MR sdk and carbide.c++ edition v1.1 for application development. I am trying to build the application using this ide but i am getting the following errors repeatedly:

the file stdio.h cannot be opened.
the file errorno.h cannot be opened.
the file string.h cannot be opened.
the file fstream.h cannot be opened.
.
.
.
.

Since these header files are included in many cpp files, the errors are repeating. Where do we change or specify the path information of these files.
I am new to this symbian application development. Please clear my doubt and give me the solution.

And one more question, Can i use Microsoft Visual Studio 6.0 to develop my application for s60 3rd edition?

Thanks in advance,
Ambika.

Check whether the paths you specified to these header files are correct.

generally these headers are in \include\libc directory

hi,

i have tried with the line(SYSTEMINCLUDE \epoc32\include\libc which you have mentioned in your reply.

Still i am getting the same errors.

Thanks,

hi ambika,

check in this path whether ur required header files are present in this path or not.
C:\Symbian\9.1\S60_3rd_MR\Epoc32\include\libc

then

go to ur .mmp file
check for this line

SYSTEMINCLUDE \Epoc32\include \epoc32\include\libc
save ur mmp clean and rebuild and reimport should link to the headers.

Hi,

I had gone through all the steps as instructed by you. But i am not getting positive result.

You asked me to clean and rebuild and reimport. I did the clean and rebuild process but not reimported. Because i am not able to import my project. When i try to import my project, I am getting the error, CTags not installed. So i am just opening the workspace and working with my application.

Thanks for ur quick replies,
Ambika.

well,

u need to reimport the project to see the changes made to the mmp file.

I also come to this problem ,
part of the original Melib.mmp is following :

/*& START_SEARCH_PATHS &*/
// NOTE: Content in this section is auto-generated, any changes are overwritten in the next update process.
SYSTEMINCLUDE \epoc32\include
USERINCLUDE ..\..\include ..\..\platforms ..\..\include\common ..\..\symbian ..\inc
#if (defined(__HIDE_WATCHER_API_V1__) && !defined(EPOC32)) || (defined(EPOC32) && defined(__HIDE_WATCHER_API_V1__) && !defined(MARM_ARMI))
SYSTEMINCLUDE \epoc32\include\variant
#endif
#if (defined(EPOC32) && defined(__HIDE_WATCHER_API_V1__) && !defined(MARM_ARMI))
SYSTEMINCLUDE \epoc32\include\libc
#endif
/*& END_SEARCH_PATHS &*/

should it be modified to this ?
/*& START_SEARCH_PATHS &*/
// NOTE: Content in this section is auto-generated, any changes are overwritten in the next update process.
SYSTEMINCLUDE \epoc32\include \epoc32\include\libc
USERINCLUDE ..\..\include ..\..\platforms ..\..\include\common ..\..\symbian ..\inc
#if (defined(__HIDE_WATCHER_API_V1__) && !defined(EPOC32)) || (defined(EPOC32) && defined(__HIDE_WATCHER_API_V1__) && !defined(MARM_ARMI))
SYSTEMINCLUDE \epoc32\include\variant
#endif
#if (defined(EPOC32) && defined(__HIDE_WATCHER_API_V1__) && !defined(MARM_ARMI))
SYSTEMINCLUDE \epoc32\include\libc
#endif
/*& END_SEARCH_PATHS &*/
