Glibtop libraries, problems with .h

[Furiwel]

HEllo guys, the problems I have is that in this little program:
#include <stdio.h>
#include </usr/include/libgtop-2.0/glibtop.h>
#include </usr/include/libgtop-2.0/glibtop/proclist.h>
#include </usr/include/glib-2.0/glib.h>


int main(){

glibtop_init();

//glibtop_cpu cpu;
//glibtop_mem memory;
glibtop_proclist proclist;

//glibtop_get_cpu (&cpu);
//glibtop_get_mem(&memory);

int which,arg;
glibtop_get_proclist(&proclist,which,arg);
printf("%ld\n%ld\n%ld\n",
(unsigned long)proclist.number,
(unsigned long)proclist.total,
(unsigned long)proclist.size);
return 0;
}

I compile it, and I start to have these stranges errors in libraries I dont even know:
(a little example because is huge)
In file included from /usr/include/glib-2.0/glib.h:80,
from /usr/include/libgtop-2.0/glibtop.h:25,
from proclist.c:2:

/usr/include/glib-2.0/glib/gstring.h:70: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token

Any idea?

ANd, if someone has a glibtop functions guide, I will be really gratefull.

Thank you very much.

Your #includes are invalid. Do this:

#include <stdio.h>
#include <libgtop-2.0/glibtop.h>
#include <libgtop-2.0/glibtop/proclist.h>
#include <glib-2.0/glib.h>

Also, the errors you are getting are indicating that you probably need some #define declared before you include the headers (or a -D name=value in your Makefile's CFLAGS variable).

[Furiwel]

Thanks you man, I will try it.

The way you did it is "non-standard", but should work. However, the normal way is to leave the leading "/usr/include/" off of the #include directives for headers found in the /usr/include tree. From the error messages, it was reading those files. In any case, looking at my version of that file, from what I can tell, it seems that possibly the 'gsize' type has not been defined. It should be defined in /usr/include/glib-2.0/glib/gtypes.h or /usr/include/glib-2.0/glib.h - in my case it is in glib.h. So, try reordering your headers like this:

#include <stdio.h>
#include <glib-2.0/glib.h>
#include <libgtop-2.0/glibtop.h>
#include <libgtop-2.0/glibtop/proclist.h>

and see what happens.

I think I resolve that problem, but now I have another one:

cpu.c:18: error: expected specifier-qualifier-list before ‘guint64’
The error is in the first line of the declaration inside the structure.
And also I get this one:
cpu.c:29: error: ‘myCpu’ undeclared (first use in this function)
inside the glibtop_get_cpu function
and this one in the printf function:
cpu.c:28: warning: incompatible implicit declaration of built-in function ‘printf’

In this code:

#include </usr/include/libgtop-2.0/glibtop.h>

#include </usr/include/libgtop-2.0/glibtop/mem.h>

#include </home/furiwel/Escritorio/PFC/cpu.h>



#include </usr/include/glib-2.0/glib.h>

#include <unistd.h>




int main(void) 

{ 
	

        

        

        glibtop_init(); 

	typedef struct _glibtop_cpu
	{
		guint64 total;				/* GLIBTOP_CPU_TOTAL		*/
		guint64 user;				/* GLIBTOP_CPU_USER		*/
		guint64 nice;				/* GLIBTOP_CPU_NICE		*/
		guint64 sys;				/* GLIBTOP_CPU_SYS		*/
		guint64 idle;				/* GLIBTOP_CPU_IDLE		*/
		guint64 frequency;			/* GLIBTOP_CPU_FREQUENCY	*/
	} glibtop_cpu;

        

        void glibtop_get_cpu(glibtop_cpu *myCpu); 

        

        printf("total:%ld\nuser:%ld\nnice:%ld\nsys:%ld\nidle:%ld\nfrequency:%ld\n", 

                myCpu.total, myCpu.user, myCpu.nice, myCpu.sys, myCpu.idle,myCpu.frequency); 

                

    	  glibtop_close();            

    	

        return(0);

}

Any Ideas?

I think I solve those problems, but then:
cpu.c.text+0xf): undefined reference to `glibtop_init'
cpu.c.text+0x50): undefined reference to `glibtop_close'

and I have the close.h header.
