Compatibility between HP-UX 10.20 cc compiler and HP-UX 11.0 aCC A.03.50

[Vladimir L Marques]

Hi there,

It's possible to maintain HP-UX 10.20 cc compiler in HP-UX 11.0 ?? I'm facing many problems migrating our applications (and we have more than 50) to this new compiler version.

thanks,

Vlad.

While it is possible to build your applications on 10.20 and run them on 11.00, it is not possible to use a 10.20 compiler on 11.00. The 11.00 development files will not match what the 10.20 compiler expects. There are many files such as crt0.o, header files, and the lib*.sl symbolic links to libraries which will not match the versions that 10.20 built programs are using.

Ok Mike, thank you.

Vlad,

Taking Mike's excellent point one step further, why don't you just copy your 10.20 apps onto the 11.0 system and run them as is.? You can then work on compiling them at your leisure.

Pete,

We are just upgrading our development environment to version HP-UX 11.0. On HP-UX 10.20 we've been using cc compiler - this is one of our compilation problems (migration from cc to aCC). Do you know if it's possible to use cc on HP-UX 11.0 ?

regards,

Vlad.

Guys,

Please forget my last question regarding "cc on HP-UX 11.0" - I've found it.

thanks,

Vlad.
