HP-UX to Linux migration
 

Hi All,

We are starting Hp-UX to Linux migration project.
It's a huge project, and I hope it's already done on lot of places.

I am looking for the forum, where I can discuss the problems which I am facing during the migration.

Currently I am looking for migrating HP-UX C code to Red-Hat.

Regards,
Amar

Greetingz!
See my post in your other thread.

I've already mentioned which forums here at LQ you could probably benefit from. It really seems like this is a double-post. Please try not to double-post.

Sorry about that. But Those are very general forms and I tried searching this topic and nothing found.
I hope there are some place where discussions are only on migration to Linux.

You might be thinking a little too broad. There doesn't appear to be a forum specific to Linux Migrations here at LQ. Things are broken down to either a general topic (like Virtualization) or very specific per-thread problems (like compiles failing with weird errors).

Do you have something like a bullet-list of problems you want to address?

Yes, actually it's a huge list where I am already working on.
I know for most of them there is no direct answer. It's always need a disscusion.

There are lot of differences in HP-UX and Linux, which I need to find it.
So it will be very helpful if there is already existing on net.

Right now, I am going with hit and trial method and finding problem one by one.

I can give you some example.
1) Find all the macro which is only avaliable in HP. Also find corresponding macro in Red-Hat
2) Fill all the external varaiable like errno. where no include needed in HP, but Linux don't work without including header files.
3) strcpy(a, b). If b is NULL it crash on Linux, but not in HP-UX.

This list contain more than 300 items for that I am working on.

By chance would the "Linux to HP-UX Porting Guide" on HPs website help out?
You might also be interested in the GCC documentation.

Thanks for the help.
I hope very soon Unix to Linux migration forum will also start, as I know currently lot of projects in USA and Canada just started.

Even COBOL->C conversion is also in place.

Closed as this is a duplicate
