Question about Compiling Ice on True64 ?

[myer]

hi.
When I compile Ice on True64, there comes many configure errors.
Then I try modifying the Makefile and ./config/Make.rules to avoid the errors, still no use.

Can anyone tell me It's possible that compiling Ice success on True64(ver5.1b) or not ?
And then some advice for compiling that ?

For we must use alpha workstation with true64, when I think of using Ice for distribute systembristol, the feasibility I must first to know. Any information would be greatly appreciated!

Thanks. Myer.

Ice is not supported on Tru64, and as far as I know, was never ported to this OS by any of our users.

If you like, you can do this port yourself; it should be reasonably easy since Ice builds with many C++ compilers, in both 32 and 64 bit mode. You'd start by writing your own <ice-root>/config/Make.rules.`uname` and edit <ice-root>/include/IceUtil/Config.h to add Tru64 conditionals.

Another possibility is to have ZeroC do this port; in this way, Tru64 could become a supported platform in the next Ice release. Please e-mail us at sales@zeroc.com if you want to discuss this option.

Best regards,
Bernard

I try to modify "Make.rules" and "Config.h", creat a file "Make.rules.OSF1" for tru64,
then run "gmake", something like only link error:

...
cxx -shared -L../../lib -o ../../lib/libIceUtil.so.2.1.2 -h libIceUtil.so.21 Base64.o Cond.o CountDownLatch.o CtrlCHandler.o Exception.o Shared.o GC.o GCRecMutex.o GCShared.o InputUtil.o MD5.o MD5I.o Options.o OutputUtil.o RWRecMutex.o RecMutex.o StaticMutex.o StringUtil.o Thread.o ThreadException.o Time.o UUID.o Unicode.o

thanks.

Segmentation fault when you link the library ... this looks like a bug in the linker or compiler. I am afraid we can't do much to help; you may want to contact HP support or the Tru64 support forums.

Cheers,

Thank you.

When I resolve it, I will go back for a conclusion.

[myer]

I changed the configure file and used gmake and gcc. And in file "IceUtil/Thread.cpp" I modified
"nanosleep(&ts, 0);"
to
"pthread_delay_np (&ts);"
to avoid the link error.

Now, it seems working.
but it is so so slow. why?
For example , with the demo "printer", it takes 2.5s for the client to connect to the server for printing a "Hello world!" message.

Help! Thanks!

[myer]

Again...

At Client, I give some "cout" info to see which statement is most slowly.
like this:
int main(...)
{
cout << "First!" << endl; //first statement;
.......
}
Run the program, after about 2.4s, message "First" is showed.

why? all this on windows is very fast.

[myer]

chang this:
OPTIMIZE = yes

then the init speed is very fast too.

On tru64, All is OK.
Thank you.

Congratulations for completing this port so quickly!

If you like, you could post a patch on the "Patches" forum with your changes: I am sure other Tru64 users would appreciate.

Thanks,
Bernard
