Compiling mysql on CENTOS

[Ni3ls]

Hi all,

Im trying to setup async mysql connection with libcod. However, no matter which github I use, I wont compile the mysql functions.
Error using iznogods github (https://github.com/iznogod/libcod)

##### COMPILE GSC_MYSQL.CPP #####
cc1plus: error: unrecognized command line option "-std=gnu++11"

So no mysql is not compiled

What the hell is going on?

The java crap can be ignored, was a thingy kung tried to add long ago but never did

I've recently added some sort of mysql detection (Since i moved my VPS to Arch Linux and the do not provide multilib mysql packages) which checks the existanse of libmysqlclient.so.18 inside /usr/lib and if its not found, mysql compilation will be skipped, if you sure you have mysql installed, just force it then, e.g set mysql_enable="true" in doit.sh after lib checks (e.g line 49)

It did compile, but I get segmentation fault by startup. No gametype or map is set at this point.

Dunno but seems unrelated to mysql, was there any other errors/warnings durning compilation?

[voron00]

Does it present in build from kung's or Mitch's repo too or just in mine?

[Ni3ls]

In all the other ones I also got segmentation fault. And they were even build without mysql.

CentOS doesn't like this function, but I have no idea why.

		char* defaultweapon_mp = (char*)malloc(MAX_WEAPON_NAME_SIZE);
void gsc_utils_init() {
    strcpy(defaultweapon_mp, "defaultweapon_mp");
    defaultweapon_mp[strlen(defaultweapon_mp)] = '\0';
} 
	

Edit: maybe try this:

		strcpy(defaultweapon_mp, (char*)"defaultweapon_mp"); 
	

[IzNoGoD]

Confirmed starting without those 2 lines, but the fix suggested doesnt work.

It works fine without the gsc_utils_init though, so there's definitely a problem in there.

This works though:

		
#define MAX_WEAPON_IGNORE_SIZE 20
#define MAX_WEAPON_NAME_SIZE 32
char defaultweapon_mp[MAX_WEAPON_NAME_SIZE];
char ignoredWeapons[MAX_WEAPON_IGNORE_SIZE][MAX_WEAPON_NAME_SIZE];
int ignoredWeaponCount = 0;

void gsc_utils_init() {
        strcpy(defaultweapon_mp, (char*)"defaultweapon_mp");
        defaultweapon_mp[strlen(defaultweapon_mp)] = '\0';
}

void gsc_utils_free() {
        //free(defaultweapon_mp);
} 
	

Not sure if this fucks up anything anywhere else, please advise.
