New AntiVir software will freeze Windows UI?

After upgrading to new Avira AntiVir, my WindowsXP sometimes stop responding requests and only mouse cursor is still alive, and all applications can't be launched and the machine is not able to be shutdown either.

In my case, restarting explorer.exe can solve this abnormal issue:
1. Press [Ctrl] + [Alt] + [Del], launch [Task Manager].
2. Find "explorer.exe" process and terminate it.
3. From [File] menu of [Task Manager], choose [New Task]...
4. Run explorer.exe again.

Porting JVM to Embedded Device

Using Infineon Wildpass as target platform. "http://www.linux-mips.org/wiki/Adm5120#ADM8668_-_WildPass".
The compilation(host) platform is Fedora 10 installed in VMware.

Files:
classpath-0.97.2.tar.gz (classpath-0.98.tar.gz, Not recommend.)
fastjar-0.97.tar.gz
libtool-1.5.20.tar.gz (libtool-2.2.6.tar.gz, Not recommend.)
zziplib-0.13.50.tar.bz2
kaffe-1.1.9.tar.bz2

Define PREFIX as "TARGET/ramdisk/usr".
Define TARGET as "mipsel-linux".
Define HOST as "i386-redhat-linux".

Building Procedure:

1. Untar all files and run "./configure; make; make install" to install programs to host machine. It will reduce some compiling troubles.

2. Compile classpath-0.97.2.tar.gz
# ./configure --prefix=${PREFIX} --target=${TARGET} --host=${TARGET} --build=${HOST} CC=${IFX_CC} CFLAGS=-O2 --disable-gtk-peer --disable-gconf-peer --disable-plugin
# make CC=${IFX_CC} STRIP=${IFX_STRIP} LD=${IFX_LD} AR=${IFX_AR} RANLIB=${IFX_RANLIB} IFX_CFLAGS="${IFX_CFLAGS}" IFX_LDFLAGS="${IFX_LDFLAGS}"
# make install

3. Compile fastjar-0.97.tar.gz, libtool-2.2.6a.tar.gz and zziplib-0.13.50.tar.bz2
# ./configure --prefix=${PREFIX} --host=${TARGET} --build=${HOST} CC=${IFX_CC} CFLAGS=-O2
# make CC=${IFX_CC} STRIP=${IFX_STRIP} LD=${IFX_LD} AR=${IFX_AR} RANLIB=${IFX_RANLIB} IFX_CFLAGS="${IFX_CFLAGS}" IFX_LDFLAGS="${IFX_LDFLAGS}"
# make install

4. Compile kaffe-1.1.9.tar.bz2
# ./configure --prefix=${IFX_ROOTFS_DIR}JVM --host=${TARGET} --build=${HOST} CC=${IFX_CC} CFLAGS=-O2 ZZIP_CFLAGS=-I${IFX_ROOTFS_DIR}JVM/include ZZIP_LIBS=-L${IFX_ROOTFS_DIR}JVM/lib
# make CC=${IFX_CC} STRIP=${IFX_STRIP} LD=${IFX_LD} AR=${IFX_AR} RANLIB=${IFX_RANLIB} IFX_CFLAGS="${IFX_CFLAGS}" IFX_LDFLAGS="${IFX_LDFLAGS}"
# make install


Issues Solved:

1. With the latest libtool-2.2.6a, kaffe may fail in configuring as:
#checking for library containing lt_dlcaller_register... no
#configure: error: Can't find the libltdl library.
Thus, to vanish the configuring error, here we install an old version, libtool-1.5.20, for building kaffe.

2. The two ZZIP related arguments are used to solve:
#checking for ZZIP... configure: error: Package requirements (zziplib >= 0.13.24) were not met: #No package 'zziplib' found

3. If you encounter cross-compiling error as following, please install kaffe to host first.
# configure: error: please set KAFFEH to the full pathname of a locally executable kaffeh
Reference from: "http://www.kaffe.org/pipermail/kaffe/2002-October/177793.html".

While compiling kaffe for host machine, you may see make failure due to "CPStringBuilder" issue.
#ERROR in java/lang/reflect/Constructor.java (at line 235)
# Modifier.toString(getModifiers(), sb).append(' ');
^^^^^^^^
#The method toString(int, CPStringBuilder) in the type Modifier is not applicable for the #arguments (int, StringBuilder)
In my case, this issue comes with classpath-0.98.tar.gz package, but it is vanished after downgrade to classpath-0.97.2.tar.gz. Maybe 0.98 version is too new?

4. Issue prompt while cross-compiling kaffe:
# trampolines.S:33:11: invalid preprocessing directive #needed # trampolines.S:46:11: invalid preprocessing directive #$fp
Commenting/removing those two lines to pass the compilation.
(Is it a correct fix? Not sure.)

5. Issue prompt while cross-compiling kaffe:
# : undefined reference to `lt_preloaded_symbols'
# ../../kaffe/kaffevm/.libs/libkaffe.so: undefined reference to `isfinite'
# ../../kaffe/kaffevm/.libs/libkaffe.so: undefined reference to `signbit'
# ../../kaffe/kaffevm/.libs/libkaffe.so: undefined reference to `g_atomic_pointer_compare_and_exchange'

Install VMwareTools in Fedora 10

Issue: Cannot use share-folder after VMWareTools installed in Fedora 10.

After googling, found a solution from internet. With the following steps, the share-folder issue has been fixed. (My machine is WinXP-SP2 with v6.0.0 build-45731 VMware installed.)

1. Download open-vm-tools source from
"http://sourceforge.net/project/showfiles.php?group_id=204462&package_id=244023".
2. Do the compilation
# tar zxvf open-vm-tools-2009.02.18-148847.tar.gz
# cd open-vm-tools-2009.02.18-148847
# ./configure --disable-unity --without-gtkmm --without-dnet --without-icu
// Need --disable-unity --without-gtkmm --without-dnet --without-icu on my machine.
# make
3. Create needed tar files for VMwareTools.
# cd open-vm-tools-2009.02.18-148847/modules/linux
# for i in *; do mv ${i} ${i}-only; tar -cf ${i}.tar ${i}-only; done
// vmblock.tar, vmci.tar, vmhgfs.tar, vmmemctl.tar, vmsync.tar and vmxnet.tar will be created.
3. Untar VMwareTools-6.0.0-45731.tar.gz, the source is from VMware software itself.
4. Copy all tar files created by open-vm-tools to vmware-tools-distrib/lib/modules/source.
5. Run VMwareTools installation
# cd vmware-tools-distrib
# ./vmware-install.pl
6. Besides, "RgbPath" is not a valid keyword in /etc/X11/xorg.conf, "startx" cannot be activated due to the error. Please comment it from L:13 of /etc/X11/xorg.conf.
