aCC Compiler error

[CRAZY SANTHOSH]

Hi all,

I am porting tripwire product on HP-UX and when use aCC Compiler I am getting following error while compilation but compilation is successfull when i use g++ compiler(3.4.3 version)

error is:

Please help me if any source code modifications has to be done or any compiler options to be provided ...

Suggesions are appreciated...

Thank you in Advance

Shalom,

To recommend source code modifications, someone might actually need to see the source code.

The compiler is telling you what lines to look at. Looks like a code review problem to me.

g++ is probably not as strict. When you throw, the copy constructor must exist and be accessible. Even if the copy ctor can be optimized out. Error 2330 occurs if not accessible.

To get error 2334 it requires that you have the wrong type of copy ctor, one without const&:
eFileOpen(eFileOpen&);

>Please help me if any source code modifications

Why would you not have const above? Did you want to modify the source? If you need to do that you need to make the field mutable or use a const_cast.

Hi Dennis,

Thank you for your help...

I am bit confused Dennis ...I am herewith sending file_unix.cpp gile along with this mail...

Please help me in this regard(What needs to be added??? or modified????)

Typically .cpp files are useless, you don't see the headers. If you compile with -E -.i, you can produce a .i file. Of course you may not want to post it here if there is valuable IP or copyrighted info in it. (Ok, this is GNU GPL.)

>Please help me in this regard (What needs to be added??? or modified????)

I need the header that declares the copy ctor for eFileOpen. As I said, you probably have:
eFileOpen(eFileOpen&) and you should have
eFileOpen(const eFileOpen&)

[CRAZY SANTHOSH]

Hi Dennis,

I tried with that -E option and Generated the intemediate file also and got the constructors ...

I will am sending you the three .h files 1.file.h

Look at this line

(TSS_FILE_EXCEPTION(eFileOpen, eFile );)

2.fileerror.h

Look at this line

#define TSS_FILE_EXCEPTION( except, base ) \
TSS_BEGIN_EXCEPTION( except, base ) \
except( const TSTRING& filename, const TSTRING& msg, uint32 flags = 0 ) \
: base( filename, msg, flags ) {} \
TSS_END_EXCEPTION()

#endif

3.fsservices.h

look at this line
virtual TSTRING GetErrString() const = 0;

[CRAZY SANTHOSH]

Find fileerror.h file in attached format

[CRAZY SANTHOSH]

Find fssserrvices.h file in attached format

[CRAZY SANTHOSH]

Find find the intermediate file in attached format

[Dennis Handly]

>Find fileerror.h file

This shows the problem, a little different than I mentioned:
explicit eFileError(const eFileError& rhs)
: eError(rhs) { mFilename = rhs.mFilename; }

Using "explicit" here causes the copy ctor to be ignored. 12.3.1(2) says that this constructor can only be used where direct initialization is used.
8.5(12) says that throw is a copy-initialization, so that copy constructor isn't considered.
So remove "explicit".

HI Dennis,

Thank you for the reply and problem got resolved ...

I removed explicit keyword from the .h file and it is working fine ...

Thanks once again for your help ...
