I ve created some sample Program

Sample.c

#include<iostream.h>
int main()
{
cout<<"Hello world";
}

/opt/SUNWspro/bin/CC -temp=/tmp -c -xtarget=ultra -xarch=v8plusa -DENABLE_ASSERT -mt -I/home1/tnpm_testuser/export/src/wm/wm_cpp_loader/libs/rwextensions/include sample.C

generated Sample.o

./Sample.o

./Sample

ksh: ./sample.o: cannot execute

I ve checked file permissions they are fine (777)

OK, what's the output from "file Sample" and "file Sample.o" along with "elfdump -e Sample" and "elfdump -e Sample.o"? ("elfdump" should be in /usr/ccs/bin)

Try compiling with this:

Code:
 /opt/SUNWspro/bin/CC -temp=/tmp -c -xarch=generic -xtarget=generic -DENABLE_ASSERT -mt  -I/home1/tnpm_testuser/export/src/wm/wm_cpp_loader/libs/rwextensions/include  sample.C

Is the code compatible when compiled without -fast or any -x* options. I recall it being very easygoing, then. If you want that extra speed, compiling for each box -fast or with the options from the tool on the prior page seems like the right direction.

Usually, when it does not run, it logs something appropriate about the CPU compatibility.

Hello

I am migrating the code written in SUN 4.3 to SUN 5.8

while linking i am getting the following errors

Code:
Undefined                       first referenced
 symbol                             in file

ld: fatal: Symbol referencing errors. No output written to msggen
*** Error code 1


I have written a sample program using the Prototypes for which it is firing out above error

#include<stdio.h>
#include<iostream.h>
int main()
{
int len=10;
char *coded = new char[len];
int *a=new int();
printf("Herllo");
cerr<<"Hello world:";
cerr << "\nString Array Out of Bounds!! index: " << ":elem"
<< " String length (0-"
<<" len" << ")\n";

delete [] coded;
delete a;
}

i could able to compile and run the program

so i am not getting any pointers to fix the issue. any pointer to fix the issue are highly appreciated.

Regards.

What are you using to link? "ld" or "CC"?

Hello,

I am working on migration of code from 4.2 to 5.8

I can complie a snippet with CC 5.8


Code:
#include<stdio.h>
#include<iostream.h>
int main()
{
int len=10;
char *coded = new char[len];
int *a=new int();
printf("Herllo");
cerr<<"Hello world:";
 cerr << "\nString Array Out of Bounds!! index: " << ":elem"
             << " String length (0-"
             <<" len" << ")\n";
int len1=strlen("idjfhdjfjtxt") + 1;
printf("%d\n",len1);
delete [] coded;
delete a;
}

Code:
CC sample.C
compiled well and good and i could see the out put when i run

Code:
CC --compat=4 sample.C
"Ccode.C", line 13: Error: The function "strlen" must have a prototype.
1 Error(s) detected.

How can i resolve this, as i am migrating my entire code during linking i am getting many symbol referencing errors as mentioned in previoues post


Thanks in advance,
Revathi R.

man strlen

You probably need to include string.h or strings.h.
