To Workaround:

# modprobe -r kvm-intel

1	# modprobe -r kvm-intel

where is the whereis

Today when I’m applying some scripts on Solaris 11Express nodes, a interesting error comeup,

  -bash: whereis: command not found

1	-bash: whereis: command not found

As on Solaris 10, we use cmd whereis(/usr/ucb/whereis) as a standard component.
(On Linux, it’s also a part of the util-linux-ng package )

Solaris 11X doesn’t include this command in default set, so turn to documents for help:

  Changes the Directory to /usr/ucb For a live CD installation, the path /usr/ucb does 
not exist by default. It can be added, along with many of the standard /usr/ucb tools by 
installing the 'compatibility/ucb' package from the repository.
  Note though that support for legacy plotters has been removed and this sees the 
removal of the following files (PSARC/2009/540):
...
...
  Other than these changes all of the commands available in /usr/ucb in Oracle Solaris 10 
continue to be available in Oracle Solaris 11 through the compatibility/ucb package.

Very lucky the command whereis is the rest for kept in compatibility/ucb package as optional.
But it’s no longer suggested to use such cmds in further SOLs, I finally gave up refresh the toolkits.

[Refrence:]
Oracle Solaris 11 ISV Adoption Guide
Solaris 11 Express Changes: Where is /usr/ucb ?
PSARC/2009/540*
*this arc shows the discussion on some port specific /usr/ucb commands,
the abandon of those codes speed up the far and away of those BSD like code.

From this point, SOL’s running faster than Linux….

chmsee doesnt work on Fedora 15 official

just found that the chmsee tool doesnt work well today. it should worked at the release version and failed when yum up2date.
check and filed a bug on this issue.

compile rose-0.9.5a-14791 on Fedora 15

rose is a nice tool, suggested when reading the book <The CERT C Secure Coding Standard>

just install the tool on my Fedora 15 node,

1. Fetch the latest source code from official website: 0.9.5a-multiplatform-14791
2. Prepare the packages needed,(I use official Java Bins configured, which can be detected by configure script)

yum install  boost-devel  gcc-gfortran

1	yum install boost-devel gcc-gfortran

3. modify the configure script incase a boost version detect failure.

8622c8622
&lt; rose_boost_version=`grep "#define BOOST_VERSION " ${ac_boost_path}/include/boost/version.hpp | cut -d" " -f 3`
---
&gt; rose_boost_version=`grep "#define BOOST_VERSION " /usr/include/boost/version.hpp | cut -d" " -f 3`

8622c8622

< rose_boost_version=`grep "#define BOOST_VERSION " ${ac_boost_path}/include/boost/version.hpp | cut -d" " -f 3`

---

> rose_boost_version=`grep "#define BOOST_VERSION " /usr/include/boost/version.hpp | cut -d" " -f 3`

**About the path , I use following line to determine, it may also works on RH related platform.

      $grep BOOST_VERSION `rpm -ql boost-devel| grep version`

1	$grep BOOST_VERSION `rpm -ql boost-devel\| grep version`

4. configure with setting, for currently fedora.15 using gcc-4.6.0.

--disable-gcc-version-check
         Disable GCC version 4.0.x - 4.4.x verification check

1 2	--disable-gcc-version-check Disable GCC version 4.0.x - 4.4.x verification check

If you do only need some(not all) languages supported, using

--enable-languages=LIST Build specific languages:
                 all,none,binary-analysis,c,c++,cuda,fortran,java,opencl,php
                 (default=all)

--enable-languages=LIST Build specific languages:

all,none,binary-analysis,c,c++,cuda,fortran,java,opencl,php

(default=all)

5. make and continue.
Before make do modify the Makefile, or the script shall not fetch the related EDG binaries for version4.6.

让办公室台式机静音

这个问题确实困扰了我好久，pc上插着耳线，想要把机箱声音关掉，只开着耳机也不容易，每次都要开机后手动去设定。

摸索了一下午终于搞定了~

在/etc/profile中加入以下几行

if ! amixer  -c0  sget "Master Mono" | grep -q off ; then
   amixer  -c0  sset "Master Mono" toggle -q
fi

if ! amixer -c0 sget "Master Mono" | grep -q off ; then

amixer -c0 sset "Master Mono" toggle -q
