The .bin is better

install form the offical .bin file

Do it as peter

this means everyting is in the same dir under ~/, very clean

peter@cow:~/Desktop$ chmod u+x qt-sdk-linux-x86-opensource-2010.01.bin
peter@cow:~/Desktop$ ./qt-sdk-linux-x86-opensource-2010.01.bin

external deps

Apart from a C++ compiler, a number of development libraries need to
be present to enable Qt Creator to build your Qt applications. On
Debian and Ubuntu, use the following command in a terminal to make
sure they are installed:

  sudo apt-get install libglib2.0-dev libSM-dev libxrender-dev libfontconfig1-dev libxext-dev

If you're using QtOpenGL, you'll also need OpenGL development
files. You can use the following command to find out which packages to
install:

  sudo apt-get install libgl-dev libglu-dev

Environment Settings

NOTE: no need to export PATH or LD_LIBRARY_PATH everything just works. check Project->Build Setting, then I understand why.

then I

root@cow:~# dpkg-query -L qt-creator|grep bin
/usr/bin/qtcreator

but qmake is not available now

so I check packages.ubuntu.com

DO:

root@cow:~# sudo apt-get install qt4-qmake

g++

gcc is installed automatically , but we still need manually install g++

try to compile tata, then No headers found

/usr/include/qt4/QtCore

and the creator

Get Started not working and missing MySql driver

I think I'd better use the bin instead

Other Tips

qt_creator_git

ldd

peter-first is compiled in creator, So creator export its own lib path
tata is compiled in apt-get qt4

basically, tomboy and my former errrors are mainly about
libfreetype.so.6 libfontconfig.so.1
and this is satisfied with apt-get qt4(or maybe sth else)
anyway no error this time.
