build qt source in vs2022 win11

by

Don't download qt source in tar.xz format, for in Windows, if we unzip it using 7zip, some deep file paths may be truncated, for example, ECMFindModuleHelpersStub.cmake referred by FindEGL.cmake in qtbase\cmake\3rdparty\extra-cmake-modules\find-modules.

This time I download qt-everywhere-src-6.2.2.zip.

In preparation, as to README.md, ActivePerl must be installed, it sucks, we must have an account of it. However, we can find another perl alternative, Strawberry Perl portable edition.

When we build, qt source root path should be short enough like d:\qt.

bld.bat

cmake --build . --parallel

if 0 == 1 (
	rem if we build QtDoc, we must add clang path to system path, otherwise we will get exit code 0xc0000135.
	set path=%path%;%clangpath%\bin
	cmake --build . --target docs
)
 
set path=%oldpath%
cd ..

Modify paths at the beginning of above bld.bat and put the batch file in the qt source root directory, then execute it.

ps1: all in one release of qt is like below url, but we should know all in one is not available since Qt 5.15.
http://download.qt.io/archive/qt/5.9/5.9.2/qt-opensource-linux-x64-5.9.2.run
And we need download online installer for Qt above 5.15 if we don't want to build from scratch:
https://download.qt.io/official_releases/online_installers/

Windows lacks non money smell softwares.

If we encouter warning C4819 when building, change system setting 'Language for non-Unicode programs' to 'US/English' and reboot.

bad security of vmware guest isolation from host

by

1. without administrative privilege, only using guest os user password, we can copy any file from guest to host by

#startup win7.vmx first.
vmrun.exe -gu guest_os_user_name -gp guest_os_user_password copyFileFromGuestToHost "E:\vmimg\win7\win7.vmx" c:\windows\system32\notepad.exe e:\notepad.exe

2. example about communication between guest and host using vmware backdoor routines:
