Boost string conversion warning

Description

Just upgraded to PostgreSQL 8.3 on my Ubuntu PC and wanted to compile the trunk version of pgRouting. Boost wrapper always gave me a warning: "Warnung: veraltete Konvertierung von Zeichenkettenkonstante in »char*«" That means something like "Warning: outdated conversion of string constants in »char*«"

Because there are so many of those warnings, would be nice to get rid of them. Looks better ;-) I don't know it's a difficult task or not.

Can you switch your system language and post the warning in English? Can you also check your compiler version?

Anton,

The compiler version is 

daniel@bougainvilla:/opt/workspace/pgRouting$ gcc --version
gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7)

Boost: 1.34.1
OS: Ubuntu 8.04

OK, I've found the reason - g++ 4.2 rejects a quoted string constant, where the function prototype has char*. Now I'm searching for a safe way to fix this. Probably, it is a good time to convert the error messages to error codes.

06/17/08 10:10:37 changed by daniel

If you change to error codes, let's file a new ticket and add a Wiki page.

06/17/08 10:36:54 changed by anton

Well, I found out that it is more easy to change char* to const char*. I'm going to do it and then I will ask you to check it with your g++ version.

06/17/08 16:15:35 changed by anton

Probably fixed with [178]. Can you please check it with your version of gcc?

06/17/08 16:31:11 changed by daniel

  • status changed from assigned to closed.
  • resolution set to fixed.

Not tested with routing query, but the warnings disappeared.
