compilation problems with glib
Hello vino ,

i have the program

# cat glibtest.c

Code:
#include <stdio.h>
#include <glib.h>

int main(){

        GHashTable *hash = g_hash_table_new(g_int_hash, g_int_equal);
        g_hash_table_insert(hash,"Virginia","Richmond");

        printf(" %s ",g_hash_table_lookup(hash,"Virginia"));
        gboolean found = g_hash_table_remove(hash,"Virginia");
        printf("The Value 'virginia' was %s found and removed \n",found ? "":"not");
        g_hash_table_destory(hash);

        return 0;
}

the compilation problems are

# gcc -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g glibtest.c -o glibtest.o
/tmp/ccElT30B.o(.text+0x20): In function `main':

cachefslog

cachefslog(1M)						  System Administration Commands					    cachefslog(1M)

NAME

       cachefslog - Cache File System logging

SYNOPSIS

       cachefslog [-f logfile | -h]  cachefs_mount_point

DESCRIPTION

       The  cachefslog	command displays where CacheFS statistics are being logged. Optionally, it sets where CacheFS statistics are being logged,
       or it halts logging for a cache specified by cachefs_mount_point. The cachefs_mount_point argument is a mount point of a cache file system.
       All file systems cached under the same cache as cachefs_mount_point will be logged.

OPTIONS

       The following options are supported. You must be super-user to use the -f and -h options.

       -f logfile      Specify the log file to be used.

       -h	       Halt logging.

OPERANDS

       cachefs_mount_point     A mount point of a cache file system.

USAGE

       See largefile(5) for the description of the behavior of cachefslog when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

EXAMPLES

       Example 1: Checking the Logging of a directory.

       The example below checks if the directory /home/sam is being logged:

       example% cachefslog /home/sam
       not logged: /home/sam

       Example 2: Changing the logfile.

       The example below changes the logfile of  /home/sam to /var/tmp/samlog:

       example# cachefslog -f /var/tmp/samlog /home/sam
       /var/tmp/samlog: /home/sam

       Example 3: Verifying the change of a logfile.

       The example below verifies the change of the previous example:

       example% cachefslog /home/sam
       /var/tmp/samlog: /home/sam

       Example 4: Halting the logging of a directory.

       The example below halts logging for the /home/sam directory:

       example# cachefslog -h /home/sam
       not logged: /home/sam

EXIT STATUS

       The following exit values are returned:

       0	       success

       non-zero        an error has occurred.

ATTRIBUTES
