Hello,

We are trying to implement the C++ development and compilation in Z/os for our project.

In my basic C++ program, during compilation through CCNDRVR, it is not recognizing the cout/cin statements

Even though I use CXX parameter option during the compilation , below errors are thrown in the IEWL link edit step. Any Idea how to resolve this, let me know if you need more information. Fyi, am using coprorcessor for compilation and link edit.

Not sure what is "coprorcessor" you are referring to, but the link errors you are gettign indicate that you do not have proper libraries in your link step. I suggest experimenting with the C++ compiler invocation in UNIX System Serivices which if properly installed will allow you to determine which data sets need to be used in the link step if you are using JCL. To get the information about what data sets are used you can invoke the compiler with xlC -v ... ?.C command and observe the pseudo jcl that this command will produce for the link step.

hi, am using MVS JCL for compiling and linking the cpp code. I do not want to invoke the unix compiler since our goal is to achieve it through MVS applications.

within IEWL JCL my STEPLIB libraries that am using are below,

SYS1.SCEERUN2
SYS1.SCEERUN

SYSLIB system libraries below,

SYS1.SCEELKEX
SYS1.SCEELKED
SYS1.SCEECPP
SYS1.SCEEBND2

Apart from this through parameter options SE(//'SYS1.SCEEH.+','SYS1.SCLBH.+') is enabled as well.. Still basic cout/cin which is part of iostream is not working.

Thanks

The suggestion to try invoking the compiler from UNIX System Serivces was meant as a way for you to discover the proper way to invoke the link step. The alternative is to take a look at 'hlq.SCCNPRC(CBCCB)' JCL procedure that shipes with the compiler and compare your JCL to the procedure. Pay attention to the procedure variable STDLIBSD which is by default C128, but if you are not using XPLINK option then you need to use C128N instead.
