warning: deprecated conversion ......

[James C. Fuller]

Fred,
  The following code compiles fine with g++  but I get the dreaded
warning: deprecated conversion from string constant to 'PCHAR {aka char*}' [-Wwrite-strings].
How would one define the struct or the assignment to remedy this?

I tried adding const to the struct

const PCHAR    sNAME;

but still get the warning.

  Thank you,
James

Will this help ...

{(char*)"bVal",vt_BYTE,0},

in front of each string literal?

[Frederick J. Harris]

I just tested that, and it seemed to work.  Before I put the (char*) before each literal in your struct array initiation I got the error too.  This compiled with Code::Blocks 10.05 without errors ...

Code: [Select]

#include <cstdio>
typedef char* PCHAR;

enum
{
 vt_UNKNOWN,
 vt_STRLIT,
 vt_INTEGER,
 vt_INT = vt_INTEGER,
 vt_SINGLE,
 vt_FLOAT = vt_SINGLE,
 vt_DOUBLE,
 vt_LDOUBLE
};

typedef struct _tagVVN
{
  PCHAR    sNAME;
  int      iTYPE;
  int      iPTRS;
}tagVVN, *LPTAGVVN;

static tagVVN atVARIANTVALUENAMES[]=
{
 {(char*)"dblVal",vt_DOUBLE,0},
 {(char*)"fltVal",vt_FLOAT,0},
 {(char*)"intVal",vt_INT,0}
};


int main()
{
 printf("vt_UNKNOWN = %d\n",vt_UNKNOWN);
 printf("vt_STRLIT  = %d\n",vt_STRLIT);
 printf("vt_INTEGER = %d\n",vt_INTEGER);
 printf("atVARIANTVALUENAMES[0].sName = %s\n",atVARIANTVALUENAMES[0].sNAME);
 getchar();

 return 0;
}

I run into that one frequently.  They must have added that warning in whatever mingw version is in 10.05, as it didn't do that in 10.02.  Sometimes ya gotta just love C++!

[Frederick J. Harris]

By the way, I got a gmail account.  My email account with my ISP still works good in terms of spam.  It doesn't lose any of that!

[James C. Fuller]

Thanks Fred works fine here but......

I have 10811 warnings in 43k+ lines of c++ source.
Might take awhile

James

[Frederick J. Harris]

Wow, I feel for 'ya James!  I've already had to fix several dozens of those.  You know, there's likely some way of manipulating the warning level to turn that silly (in my mind anyway) warning off.  For me, it was always easier to fix them than to investigate. But if I had thousands of them, I might rethink that!

[James C. Fuller]

Fred,
  Oh there is a way to turn them off: -Wno-write-strings
I just started compiling bc9 as a g++ app so I could use the pcre library class code for parsing and got a bit carried away to see how many warnings there actually were. Now .... I CAN"T STOP!!!!!

James

[James C. Fuller]

Fred,
  I'm done!
It really should not have taken as long as it did. I had a brain cramp and negelected to notice a  redefinition of fprintf -> 10k+ warnings.

I now have 10 warnings on 43k lines of code; all for unused variables I use for debugging.

This all started because I wanted to add properties to bc9 as I had done to Bcx8.

I began windows with VB and of course that was the way it was done. The original PBWIN did not have them as it
did not have any classes of anytype. With the new COM interface I lobbied hard for properties during the early beta.

Now that I am working with bc9/c++ I miss them.
I found an implementation that has limitations but does work rather well; just a lot of coding in c++ but not to worry as I don't code in c++! I code in bc9.

Glad its working out! 

VB was my first Windows programming too, back about 1996.  VB4 I think.  Before that all I did was DOS.  I never even used Windows before that, unlike many who did 16 bit Windows. 

I spent a lot of time since last weekend working with that 64 bit GNU compiler you turned me on to.  I enjoyed it.  I wanted to learn a little bit more about 64 bit code.  I really have absolutely no need for it, nor can I even envision any need for it by myself at any point, but being a coder, I was interested to play with it. 

I managed to get two interesting programs I had written up a couple years back on a command line compiling tutorial I had been working on working in both 32 bit and 64 bit versions, UNICODE or ansi, GNU or Microsoft compilers working perfectly.  Same source code exactly.  Think about it.  That's a lot of conditional compilation, macros, #defines, and other fancy stuff!  Maybe I can post that tomorrow.

Next week I gotta get back to real work!
