Need help with aCC compiler version 6

nayeem khan — Thu, 03 May 2007 05:50:19 GMT

Hi

We were using aC++ compiler version 5 and now we are migrating to new Version 6 Compiler

But one of the module which compiles fine but on execution throws a run time error

"aCC runtime: Use of "-mt" must be consistent during both compilation and linking
.
ABORT instruction (core dumped)"

This means some of the libraries/archives are not compiled with "-mt" option,this error was not appearing with Version 5 compiler may its a new compiler feature

Can someone tell me how to switch off this feature in version 6 compiler

Thanks in advance

Hi,

do exactly what the compiler tells you:
if you want to create a multithreaded application, every part of it need to be compiled/linked with the option '-mt'.

If it worked before without using '-mt' in all calls to aCC, it was by mistake.
Other UNIXes/Compilers behave exactly this way, as well.

You switch off this error by not linking with libpthread. -mt is a required option for making multithreaded aC++ applications.

It it didn't appear with aCC5, it is either a fluke, (the heap wasn't zeroed), or aCC6 generates better/smaller code.

There is a bug with one version of the aC++ runtime lib that will give false missing -mt errors if you have illegally linked a shared lib with the aC++ runtime libs in the wrong order. You can fix that by going to the latest:
PHSS_35978

>Peter: do exactly what the compiler tells you:

Right.

one of the TAO libraries was not compiled with -mt option
