The Question is: Hi, I am working on an DEC ALPHA 433 using OVMS 7.1 porting a software package that was written under UNIX. Unfortunatlly my customer is using OVMS 6.2 and the c++ compiler the I was using is not compatiable. The Port wend fine with that compiler. So we aquired a C compiler version 5.5-0003 to do the job. I am getting massive problems while using simple calls like chmod, open, opendir, bind, ioctl, fileno, etc. My questions is must I uninstall the C++ compiler before I can continue? I noticed that in the header files that the 5.5 compiler is accessing a version check for 7000000 is done. If so How do I do this? I am not an expert on the OVMS system. Please help Thanks in advance Bahram Djavidan ZING/SOFT Berlin Germany The Answer is : Please be cautious when indicating the system -- the OpenVMS Wizard is not aware of any "DEC ALPHA 433" system sold by DIGITAL or Compaq. You will want to use the backport library available in DEC C V5.6 and later, or you will want to upgrade to OpenVMS Alpha V7.1 or later, to gain access to the largest set of C routines. (The current DEC C release is V6.0, and the current OpenVMS Alpha release is V7.2.) You will want to use the /PREFIX=ALL qualifier on the DEC C compilation, to allow the LINKER to automatically locate the routines in the DEC C run-time library. (Routines such as "open" could not be included in the default library as there are many user programs containing routines with this name that would encounter duplicate symbol errors. As a result of this, DEC C can add a prefix of "decc$" to the C library routine calls and thus routines such as decc$open can be located by the LINKER.) Note that ioctl and certain other calls can be specific to a platform or to a particular device driver.
