Compiling mysql on CENTOS

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)

Code:

---

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

---

So no mysql is not compiled

Code:

---


[olger@static libcod_iznogod]$ ./doit.sh cod2_1_0
##### COMPILE cod2_1_0 LIBCOD.CPP #####
##### COMPILE cod2_1_0 GSC.CPP #####
##### COMPILE cod2_1_0 GSC_PLAYER.CPP #####
##### COMPILE cod2_1_0 GSC_UTILS.CPP #####
##### LINK libcod2_1_0.so #####

---

using Voron00 github (https://github.com/voron00/libcod)

Code:

---

##### WARNING: MYSQL libs not found, MYSQL compilation skipped #####

---

using kungs github (https://github.com/kungfooman/libcod)

Code:

---

##### COMPILE JAVA_EMBED.C #####
Ignore java_embed.c, because java_enable==false (e.g. because the dir $java_jdk=/root/helper/openjdk8 does not exist)

---

Code:

---

##### COMPILE cod2_1_0 LIBCOD.CPP #####
##### COMPILE cod2_1_0 GSC.CPP #####
##### COMPILE cod2_1_0 GSC_PLAYER.CPP #####
##### COMPILE cod2_1_0 GSC_UTILS.CPP #####
##### LINK libcod2_1_0.so #####

---

mysql not compiled?!

using mitchs github (https://github.com/M-itch/libcod)

Code:

---

##### WARNING: Skipped java_embed.c because OpenJDK 8 does not exist #####

---

Code:

---

./doit.sh cod2_1_0

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.

Code:

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

Thats all.



BTW: Im using this method to compile
http://killtube.org/showthread.php?2...ll=1#post10702

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

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.

PHP Code:

---

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:

PHP Code:

---

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


---

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:

PHP Code:

---


#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.

To follow up on the previous thing: the malloc() the the non-function space (outside of any function) returns a NULL-pointer.

The libcod code doesnt check for that, and as a result, the code will crash.

Better fix which follows http://stackoverflow.com/questions/1...h-file-scope-c

PHP Code:

---

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

void gsc_utils_init() {
        if(defaultweapon_mp == NULL)
                defaultweapon_mp = (char*)malloc(sizeof(char) * MAX_WEAPON_NAME_SIZE);
        if(defaultweapon_mp == NULL)
                printf("Failed to malloc defaultweapon_mp\n");
        strcpy(defaultweapon_mp, (char*)"defaultweapon_mp");
        defaultweapon_mp[strlen(defaultweapon_mp)] = '\0';
}

void gsc_utils_free() {
        free(defaultweapon_mp);
}

So it does now compile without any problems.
However, when I use the this script to setup mysql
https://killtube.org/showthread.php?...ll=1#post13719

I get this error

Code:

---

unknown function: (file 'maps/mp/gametypes/_mysql.gsc', line 136)
        mysql_close(mysql);
        *

---

However, when I open gsc.ccp

Code:

---

        {"mysql_init"              , gsc_mysql_init              , 0},
        {"mysql_real_connect"      , gsc_mysql_real_connect      , 0},

        {"mysql_async_initializer" , gsc_mysql_async_initializer , 0},
        {"mysql_reuse_connection"  , gsc_mysql_reuse_connection  , 0},
        #endif

What can be the problem?

Sorry for double post.
I added the fix of Iznogod to the github of Kungfooman and I can connect to my database :)
Thanks for all the help !
