Re: [ROOT] Compilation trouble on Solaris 2.8 with CC 5.3

Hi Rene,

The problem only occured during linking.

After not finding any solution at the root web pages, I searched the
solaris related news-groups and found that this problem was described
there.
I played around a bit with several options and finally I added the option
-xar at the LDFlags in Makefile.config - *NOT* at the start of the
compilation, but when the error the first time happens.
Then root compiled and finally also my program.

But...
Unfortuately I discovered this morning that I in fact can compile my
program, but can not start the root interpreter....

;-(

After deleting the current ROOT installation and restaring from scratch it
compiled without any modifications! (Remark: Yesterday I also started from
scratch!)

One difference was that I only compiled with gmake instead of gmake -j 2,
ie I only used one processor instead of all two.

I have no idea if this was the reason (gmake -j 2 works on Linux).


I would be interested if anybody else had similar problems with Solaris
2.8 and Compiler 5.3.
Otherwise the problem could be related to our installation.
