问题应该处在最近安装的软件上，检查系统的历史记录，发现最近只安装过SKYPE 1.3。
有可能是skype的问题，于是google之。找到了答案：

There is a solution for the Skype microphone problem:

1.

Install Skype 1.3 beta (see http://www.macewan.org/2006/06/28/skype-13-ubuntu-dapper/#comments)
Do NOT run it during working on next point.
2.

Go to your sound channel settings (i.e. right-click the reproductor icon in the Gnome interface and select “Open volume settings”) and make sure that both Microphone AND Capture channels are selected as recording devices.
And yes, I also had Capture off in Breezy with Skype 1.2, but now it is needed to have it on or the microphone will not work. It is probably good idea also to enable the capture “output” which in fact enables automatic volume level control of the microphone.
3.

Run Skype

Another possibly affecting factor is that I have installed the oss-alsa package as result of my previous attempts to get skype to work (I do not know if it matters or not).
This way it works for me, I hope it will for you also…

apt-cache search mapserver
cgi-mapserver – cgi module of mapserver
mapserver-bin – mapserver binary utilities
mapserver-doc – documentation for mapserver
perl-mapscript – perl mapserver library
php4-mapscript – module for php4-cgi to use mapserver
php5-mapscript – module for php5-cgi to use mapserver
python-mapscript – python mapserver lib

debian stable中是4.4.1，testing和unstable是4.8.3版本。

并且发现现在安装mapserver好简单了：

./configure –with-ogr –with-gdal –with-geos –with-proj –with-postgis –with-php=/usr/include/php5/
make
sudo cp php_mapscript.so /usr/lib/php5/20051025/
#// 加入php_mapscript.so的extensions
sudo nano /etc/php5/apache2/php.ini
sudo /etc/init.d/apache2 restart

已经安装了apache2-mpm-prefork，libapache2-mod-php5包。

QMAKE_INCDIR_QT = /usr/local/qt4-w32/4.1.2/include
QMAKE_LIBDIR_QT = /usr/local/qt4-w32/4.1.2/lib

QMAKE_LINK = i586-mingw32msvc-g++

# ne pas oublier le -mwindows ici
QMAKE_LFLAGS = -mthreads -Wl,-enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -mwindows

QMAKE_RC = i586-mingw32msvc-windres

QMAKE_STRIP = i586-mingw32msvc-strip

6、QT4的跨平台编译支持就完成了，以后可以这样编译WINDOWS程序：
qmake-qt4 -project
qmake-qt4 -spec win32-x-g++
make

下载源码，解压缩：

cd sqlite-3.3.5
nano Makefile.linux-gcc
#modify:
#TOP = ../sqlite-3.3.5
#这个修改不知道有没有意义

# Note: SQLite is using for example its own parser (lemon) which must be compiled first for Linux

make -f Makefile.linux-gcc lemon keywordhash.h

cp Makefile.linux-gcc Makefile.mingw-gcc

nano Makefile.mingw-gcc
# modify Makefile.mingw-gcc (BCC,TCC,AR,RANLIB):
# 修改一下相关部分：
# BCC = i586-mingw32msvc-gcc -g -O2
# TCC = i586-mingw32msvc-gcc -O6
# AR = i586-mingw32msvc-ar cr
# RANLIB = i586-mingw32msvc-ranlib

# delete tclsqlite.o from LIBOBJ in main.mk

make -f Makefile.mingw-gcc libsqlite3.a

i586-mingw32msvc-g++ –shared -o sqlite3.dll \
-Wl,–out-implib=libsqlite3.dll.a \
-Wl,–export-all-symbols \
-Wl,–enable-auto-import \
-Wl,–whole-archive libsqlite3.a \
-Wl,–no-whole-archive -lmingw32

i586-mingw32msvc-strip sqlite3.dll
cp sqlite3.dll /usr/i586-mingw32msvc/bin/
cp libsqlite3.dll.a /usr/i586-mingw32msvc/lib
cp sqlite3.h /usr/i586-mingw32msvc/include

下载allportscombine包，然后：

./configure –with-msw –target=i586-mingw32msvc –host=i586-mingw32msvc –build=i386-linux –enable-unicode –prefix=/usr/i586-mingw32msvc/
make
make install

注意编译的时候要分两步走，不能象G++那样一步到位：

i586-mingw32msvc-g++ -c -o minimal.o minimal.cpp `/usr/i586-mingw32/bin/wx-config –cxxflags`

i586-mingw32msvc-g++ -o minimal.exe minimal.o `/usr/i586-mingw32/bin/wx-config –libs`

因为wxWidgets是以动态库的方式编译的，还需要拷贝相关的DLL：

cp /usr/i586-mingw32msvc/lib/wx*.dll .

同时，还要拷贝mingw32的一个库过来：

cp /usr/share/doc/mingw32-runtime/mingwm10.dll.gz .
gzip -d *.gz

然后就可以进行测试了：
wine minimal.exe

mv Thuban-1.1.0 thuban-1.1.0
cd thuban-1.1.0
nano debian/control
#修改几个相关依赖，主要是gdal和python相关的部分
#libwxgtk2.6-dev, libgdal1-1.3.1-dev, python-wxgtk2.6
dch -i
dpkgbuildpackage -rfakeroot
cd ..
sudo dpkg -i *.deb

我印象中原来thuban是用C＋＋写的，怎么现在改成python+wxWidgets了。

./configure –prefix=/usr
make
checkinstall -D
sudo dpkg -i *.deb
