There are significant differences between 4.2 and 5.8 as far as C++ source code and C++ compilers are concerned. For starters you are going to have to provide prototypes for each function either through a header or in the source code itself.
yes when i included string.h it is working fine..it just a sample code
but for my entire project to migrate, any helpful information plzz ,as i vent found even in migration guide to include additional libraries.

I am facing linking issues in the project i feel it is because of the standard libraries, i included standard libraies of SUN CC 5.8
actually code is written in SUN CC 4.3
will theire be any compilation option to resolve linking issues
any solution to this problem is highly appriciated
I am migrating the code written in SUN 4.3 to SUN 5.8
while linking i am getting the following errors
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.

Assuming that this is the problem you're still seeing, have you recompiled everything with the new compiler?
It looks like the compiler can't find the C++ run-time libraries. Or it can't find the proper version...
There's probably a command-line option for the CC command to have it emit intermediate steps, so we can see what commands are actually getting run, especially the final link step.
Or, you can just run that CC link command under truss, and just truss the execve() calls:
You can also post here, where you're likely to get help from someone who actually works for Oracle on the Studio compilers:
Usually, good code uses #include and that provides any declaration or prototype, but if you wrote without prototypes, you have to add them to your includes, usually. I often put the calling code after the called code, so the prototype is the full subroutine, but if called externally, you need an include with a prototype (or hand made prototype copies all over the place, which is bad practice).
for a header file like iostream.h, there will be some .so file right, so do i need to link that .so file, if include header in my code, do i have to include corresponding .so file, explicitly???
as i could see Iostream_init::Iostream_init(void) Iostream_init::~Iostream_init(void)
these two prototypes in iostream.h, while linking i am getting Symbol referencing errors as mentioned in the thread.
so is there any way i can trace the corresponding .so file for .h file

Hi all,
currently I'm facing a issue in linking a .so file.
In my build machine, I've libcrypto.so.6 and there is a softlink as libcrypto.so.
In my make file I'm trying to link to the lib using -L -lcrypto and it is success and created my test.exe.
When I copy this test.exe to other... (4 Replies)

Hi,
I'm new, here, and I'm searching for a simple solution for a simple problem.
I'm working on RedHat 4.4.6-4 through a CentOS Virtual Machine and due to some reasons I must compile my C++ codes with these two different g++ versions: 4.4.6 and 4.2.2.
The fact is that I should be able to... (4 Replies)

Hi all.
I have a simple question.
There's a way to install under AIX system (5.3) two different compiler version, i.e. ibm xlf fortran 11 and 12?
Seems that smitty doesn't allows user to change the default installation path; it only allows you to save the replaced files of the superseded... (1 Reply)
