Java also uses compiler. So, if we meet with compile error, we need to check compile option.

[Cases]
Error : "Access restriction : the field ..." [in Eclipse]

'Project' -> 'Properties' -> 'Java Compiler' -> 'Errors/Warnings' -> 'Deprecated and restricted API' -> Forbidden reference (access rule) -> change from 'Error' to 'Warning'.
=> We can make compile success. But, please keep it mind... using forbidden reference is not recommended!!

Using external Jar [in Eclipse]

Right click on Project -> Properties -> select 'Java Build Path' -> select 'Libraries' tab -> select 'Add External JARs' button...

[Win32][Tips] Creating Window...

* Making Blended & Clink-Through window

We can use following window style option at CreateWindowEx().
WS_EX_TRANSPARENT -> click-though
WS_EX_LAYERED -> alpha-blended window.

We can changne configuration in runtime by using following API.

SetLayeredWindowAttributes(...)
: Layered window's attributes (Alpha value, Transparet color etc) can be changed.

SetWindowLong(...)
: Window의 Ex Style can be changed. We can set or clear "Click-Through" by setting or clearing WS_EX_TRANSPARENT attributes.

* We can remove menu

by set 'lpszMenuName' as 'NULL' at 'WNDCLASSEX' structure when 'CreateWindowEx' is called.

* We can change initial background color of Window

by creating brush of preferred color at 'hbrBackground'.

* We can remove 'titlebar' and 'boarder'

by set 'dwStype' parameter as 'WS_POPUP' style.

* (Issue) Maximized window covers Taskbar!

We can resolve this issue by using 'WM_GETMINMAXINFO' and 'SystemParametersInfo/SPI_GETWORKAREA'.
('WM_GETMINMAXINFO' is sent when Window is moved or Window's size is changed.)

Let's put following code in the handler of 'WM_GETMINMAXINFO'.

MINMAXINFO* pi = (MINMAXINFO*)lParam;
RECT        r;
SystemParametersInfo(SPI_GETWORKAREA, 0, &r,0);
memset(pi, 0x00, sizeof(MINMAXINFO));
pi->ptMaxSize.x = r.right - r.left;
pi->ptMaxSize.y = r.bottom - r.top;
pi->ptMaxPosition.x = r.left;
pi->ptMaxPosition.y = r.top;

[Tips] Cross-Compiling on Windows for Linux

Have you ever wanted to compile Linux binaries under Windows? This is how it

happens:
1. Get Cygwin setup.exe: http://www.cygwin.com/
1.1. Run setup.exe and continue to package selection list.
1.2. Under Devel catagory select tools you need for compiling your source. For example 'GNU make'.
1.3. Finish installing.

2. Get linux cross-compilers for cygwin:
"cygwin-gcc-linux.tar.bz2" (68.2 Mb). md5sum: 340e91a346f5bb17e660db10e43005b8
These compilers are made with crosstool 0.28-rc37. This package contains:
gcc-3.3.4 and gcc-2.95.3 for i386 (glibc 2.1.3) and gcc-3.3.3 for amd64
(glibc 2.3.2).

--------------------------------------------------------------------------------

Note! There is now newer version of GCC avaible with glibc 2.3.2:
"cygwin-gcc-3.3.6-glibc-2.3.2-linux.tar.bz2 (i386, x86_64)".
2.1. Copy 'cygwin-gcc-linux.tar.bz2' to 'c:\cygwin' or install directory which you selected in setup.exe.
2.2. Open Cygwin shell and change directory to root with 'cd /'.
2.3. Uncompress to Cygwin root with command:
'tar -jxvf cygwin-gcc-linux.tar.bz2'.

Cross-compilers are installed under '/opt/crosstool'. You can use them directly or with commands: gcc-linux, g++-linux, gcc-linux-2.95, g++-linux-2.95, gcc-linux-x86_64 and g++-linux-x86_64.

[Tips] cygwin 'make' issue

Error when executing shell command in "Cygwin make"
Here is the case.

path=c:\cygwin\bin; (...omitted... );; (...omitted...)

Take you attention to ';;' - two consecutive semicolon.

In above path environment, executable binaries like 'cp', 'mkdir' that are in 'c:\cywin\bin', works well. But, shell command like 'cmd' raise error something like "command not found".

After removing ';;' - consecutive semicolon (empty path) -, all works well.

So, here is my inference.

"Cywin make" executes command by following order.
  1. searching path environment to file executable binary.
  2. regards command as 'shell command' and try to execute.

In case that ';;' is appeared in the path, "Cygwin make" cannot recognize path after ';;'. So, executables located in the directory those are before ';;' works well. But, those are not, "Cygwin make" treats it as "shell command" and raises error (there is no shell command like this...).
