Last weekend I've upgraded the OS on my Dell Inspiron 2650 laptop, from Solaris 10 GA to Solaris Nevada Build 17 (aka snv_17 or Solaris 11). In fact, I have no plans to upgrade it in imminent future, but thanks to an unexpected power outage, that made my laptop sleep for few hours, after running 57 days continuously. So, I took that opportunity to do, some of the things that I have been keep postponing for quite a few days:Prepare the system to install OpenSolaris bitsThis is the major reason for the upgrade; but I'm not sure if I'll be able to...

Solaris 10: Recovering from a Runtime Linker Failure III
Posted on 21:07 by Unknown
With the arrival of Solaris 10, the instructions of Recovering from a Runtime Linker Failure web page became obsolete. Since this problem appears to be very common, thought it would be useful to document it.Symptom: For all commands, system responds (only) with the following error: Cannot execute /usr/lib/ld.so.1Due to the Solaris Process Model Unification, all static binaries were removed from Solaris 10 distribution. One simple workaround is to pro-actively copying the essential static executables...

Movie Spoilers
Posted on 20:43 by Unknown
At last I was able to watch the movie Book of Shadows - Blair witch 2, from the beginning to the end. It is a long, boring, sick flick which offers nothing, but lots of weirdness and insane brutality (I was holding back on The Texas Chainsaw Massacre, for the same reason; that's another story). Nothing really happens in the middle {of the movie}; and it is hard (and painful) to watch the illusions and delusions of the characters throughout the movie.Anyway the main idea of this post is not to write a review, but to provide a web resource that has...

Sun Studio 9: RR or GA?
Posted on 13:17 by Unknown
The other day I was trying to build a large enterprise application with Sun Studio 9 C/C++ compilers and with profile feedback optimization. For some reason, iropt (code optimizer) failed with the error: compiler(iropt) error: heap_free: misaligned argument(0x666f2a3e). As a first step to see if this is a bug, I thought of installing SS9's backend patch 115983-04; but surprisingly the patch installer refused to install the patch. Even though it doesn't make any sense, I tried to install the patch 115983-01, before installing 115983-04, with no...

Sun Studio C/C++: Annotated listing (compiler commentary) with er_src
Posted on 18:10 by Unknown
Wouldn't it be nice if we know what exactly the compiler did when we specify a set of optimization flags on compile line? We specify a wide variety of compiler options with the hope that the resulting binary performs better. But unless we know for sure that using a certain compilation flag helps, most of the times it appears that the compiler is doing nothing, and even we may think that certain options were there just to give placebo effect to the user.Sun ships a tool called er_src with Sun Studio compilers; so the users can examine or have a...
