Find the line 
$(GEN): PRIVATE_CUSTOM_TOOL = java -jar $(ANTLR_JAR) -fo $(dir $@) $<
Change it to 
$(GEN): PRIVATE_CUSTOM_TOOL = java -Xmx512m -jar $(ANTLR_JAR) -fo $(dir $@) $<

error LNK2005: * already defined in *.lib(*.obj)

Problem:

When I build Seahorse in branch bsquare, sometimes I got lots of linking error like this

error LNK2005: * already defined in *.obj

I’m sure it had been successful built before, but it doesn’t work now.

Solution:

I found it can be avoid if putting /FORCE:MULTIPLE into build options.

Right click on project -> Properties -> Linker -> Command Line -> Additional Options -> add /FORCE:MULTIPLE

(It just a first-add, please see the first reference for root cause.)

error C3861: '_ASSERTE': identifier not found

Error:
error C3861: '_ASSERTE': identifier not found

Solution:

The reason for this is, there is a crtdbg.h in project. so #include crtdbg.h goes to own crtdbg.h

1. In my case, tt is caused _ASSERTE doesn't defined in wceshunt.

    Please remove path wceshunt\include from include directories.

2. If the path already be removed, such as project icu.

    Please add C:\Program Files\Microsoft Visual Studio 9.0\VC\include to include directories. It should be added ahead wceshunt\include if you don't remove wceshunt from include directories.

[bash] $'\r': command not found

Error:
I got message below when I execute a bash script.
D:/asmbin/gnuasm: line 2: $'\r': command not found
D:/asmbin/gnuasm: line 4: $'\r': command not found

Solution:
It is caused by end of line is Windows style '\n\r'
Unix think the eol should be '\n'
Mac think the eol should be '\r'

The bash is unix environment, so we have to change '\n\r' to 'n'.
I use notepad++ as editor to fix the script.

[Webkit] error LNK2019: unresolved external symbol localtime_s referenced in function localtimeOffset

When I build webkit with WinCE 6.0 SDK, I got the error message as title.
error LNK2019: unresolved external symbol localtime_s referenced in function localtimeOffset

To solve the problem, I remove the code in bold font below.

#if !defined(HAVE_LOCALTIME_R) && !defined(HAVE_LOCALTIME_S) && \
     defined(_MSC_VER) && defined(_CRT_INSECURE_DEPRECATE)
//#define HAVE_LOCALTIME_S 1
#endif


After that, I got the error message below.
error C2040: 'localtime' : 'tm *(const time_t *)' differs in levels of indirection from 'int ()'

To solve the problem, I add the code before where function localtime is called.
struct tm *__cdecl localtime(const time_t *t);

#include "stdafx.h" #include "stdlib.h" int _tmain(int argc, _TCHAR* argv[]) {     system( "cd c:\\windows\\system32");     system( "notepad.exe C:\\1.txt");     return 0; }

Example for execute system call for WinCE

#include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) {     SHELLEXECUTEINFO ExecuteInfo;     memset(&ExecuteInfo, 0, sizeof(ExecuteInfo));       ExecuteInfo.cbSize       = sizeof(ExecuteInfo);     ExecuteInfo.fMask        = 0;                   ExecuteInfo.hwnd         = 0;                   ExecuteInfo.lpVerb       = _T("open"); // Operation to perform     ExecuteInfo.lpFile         = _T("\\storage card\\myBrowser.exe"); // Application name     ExecuteInfo.lpParameters = _T("--shell"); // Additional parameters     ExecuteInfo.lpDirectory  = 0; // Default directory     ExecuteInfo.nShow        = SW_SHOW;     ExecuteInfo.hInstApp     = 0;       ShellExecuteEx(&ExecuteInfo);     return 0; }

[Platform Builder] Launch AP when boot up in WinCE

I would like to launch an application when the WinCE device boot up, the AP I made is named 'test.exe'

Step 1:
Copy 'test.exe' along with its necessary dll and resource files into 'C:\WINCE700\platform\SDK_Name\FILES'
All files in the folder will be copy into the object folder (release/debug folder) after project build.


Step 2:
Modify file 'C:\WINCE700\platform\SDK_Name\FILES\platform.bib'
Add 'test.exe $(_FLATRELEASEDIR)\test.exe NK SH' in end of file, but before '; @CESYSGEN ENDIF CE_MODULES_DEVICE'

Step 2.1 (Option):
If you hope your .exe file locate at '\MyFiles\exe' folder, you should modify  'C:\WINCE700\platform\SDK_Name\FILES\platform.dat'

First, add folder into root, add script
root:-Directory("MyFiles")
then, add folder into MyFiles, add script 
Directory("\MyFiles"):-Directory("exe")
Final, add file into \MyFiles\exe, add script
Directory("\MyFiles\exe"):-File("test.exe", "\Windows\test.exe")

Step 3:
Modify file 'C:\WINCE700\platform\SDK_Name\FILES\platform.reg'
Add following statement in end of file, but before '; @CESYSGEN ENDIF CE_MODULES_DEVICE'
[HKEY_LOCAL_MACHINE\init]
"Launch300"="bsqBrowser.exe --shell"

If there is already exist [HKEY_LOCAL_MACHINE\init] , you can just append "Launch300"="bsqBrowser.exe --shell" after exist statement.
The number 300 is the order of initialization, you should give a number beyond exist statement. Avoid using the number smaller than 100 to prevent conflict to system program.

Step 4:
Build, make image and attach device.

Saturated Arithmetic

In general binary operation that 11111111（255）+00000001（1）＝100000000（256）

The operation result will be 0 for 8 bit Adder, because the processor is 8 bits only.

If a processor support saturated arithmetic, 255+1 would be 255 (stop at max or min value), and it would not overflow or underflow.

[Platform Builder] A script required for this install to complete could not be run.

Problem:
When I install the QFE 2011_Rollup for CE6.0 Platform Builder, I got an error message below.
There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor.

Solve:
Right click on the msi, select the Compatibility tab, and check the box that says "Run this program in compatibility mode for". Leave the rest as is, and it should install after that. You may also need to do the same thing for some of the other QFE's.

    const int count = 10;
    int number[count] = {0};

    printf("Before: ");
    int i;
    for(i = 0; i < count; i++) {
        number[i] = rand() % 100;
        printf("%d ", number[i]);
    }
    printf("\n");

    quickSortEx(number, count, true, 0, count-1);

    printf("Afer: ");
    for(i = 0; i < count; i++)
        printf("%d ", number[i]);

    printf("\n");
    return 0;
}

void quickSortEx(int number[], int count, bool desc, int left, int right)
{
    qsort(number, count, sizeof(number[0]), cmp);

    if (desc)

[C++] Create GUID

You can create GUID by using CoCreateGuid API.
I copy example source code from my reference article for memo as below.

#include "stdafx.h" #include <objbase.h> #include <string> using namespace std; wstring GetGUID() {     _TUCHAR *guidStr = NULL;     GUID *pguid = new GUID;     CoCreateGuid(pguid);     // Convert the GUID to a string     UuidToString(pguid, (RPC_WSTR*)&guidStr);     delete pguid;     return wstring(guidStr); } int _tmain(int argc, _TCHAR* argv[]) { wstring guid = GetGUID();     wprintf(guid.c_str());     return 0; }

[MS SQL] Performance counter registry hive consistency check

To avoid meet the problem again, I memo the solution here.

While installing SQLServer 2008 on Windows 7 64bit - Traditional Chinese Version.
I got an error message told me "Performance counter registry hive consistency check".
It would not happen on English version OS.
Here is an article will help.
http://www.dotblogs.com.tw/lastsecret/archive/2010/06/14/15865.aspx

In addition, you should execute window update to download Visual Studio 2008 sp1 if you like to install SQL Server 2008 Management Studio. Otherwise you'll got error message as "Another version of Microsoft Visual Studio 2008 has been detected on this system that must be updated to SP1.  Please update all Visual Studio 2008 installations to SP1 level, by visiting Microsoft Update."

Watch Virtual / Physical Memory Usage

With previous article http://twnin.blogspot.com/2012/05/watch-process-memory-usage.html
There is another way to watch memory usage in program with win32 api.

    MEMORYSTATUS ms;
    ms.dwLength = sizeof(ms);
    GlobalMemoryStatus(&ms);

    const int nBufSize = 512;
    TCHAR chBuf[nBufSize];
    ::ZeroMemory(chBuf,nBufSize);

    // Process-specific info (for calling process)
    wsprintf(chBuf,_T("TotalVirtual: %ld\n"), ms.dwTotalVirtual);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("AvailVirtual: %ld\n"), ms.dwAvailVirtual);
    OutputDebugString(chBuf);

    // Process virtual memory usage (reserved + commit)
    wsprintf(chBuf,_T("UsageVirtual: %ld\n"), ms.dwTotalVirtual - ms.dwAvailVirtual);
    OutputDebugString(chBuf);

    // System info
    wsprintf(chBuf,_T("MemoryLoad: %ld\n"), ms.dwMemoryLoad);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("TotalPhys: %ld\n"), ms.dwTotalPhys);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("AvailPhys: %ld\n"), ms.dwAvailPhys);
    OutputDebugString(chBuf);

    // System usage
    wsprintf(chBuf,_T("UsagePhys: %ld\n"), ms.dwTotalPhys - ms.dwAvailPhys);
    OutputDebugString(chBuf);

    // Unused/unsupported
    wsprintf(chBuf,_T("TotalPageFile: %lu\n"), ms.dwTotalPageFile);
    OutputDebugString(chBuf);
    wsprintf(chBuf,_T("AvailPageFile: %lu\n"), ms.dwAvailPageFile);
    OutputDebugString(chBuf);

Watch Process Memory Usage

To watch current process memory usage, we can use GetProcessMemoryInfo to get paging information.
It is sample code below.

    HANDLE hProcess = ::GetCurrentProcess();
    PROCESS_MEMORY_COUNTERS pmc;
    pmc.cb = sizeof(PROCESS_MEMORY_COUNTERS);
    ::GetProcessMemoryInfo(hProcess, &pmc, sizeof(pmc));

    const int nBufSize = 512;
    TCHAR chBuf[nBufSize];
    ::ZeroMemory(chBuf,nBufSize);

    wsprintf(chBuf,_T("PageFaultCount: 0x%08X\n"), pmc.PageFaultCount );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("PeakWorkingSetSize: 0x%08X\n"),
    pmc.PeakWorkingSetSize );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("WorkingSetSize: 0x%08X\n"), pmc.WorkingSetSize );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("QuotaPeakPagedPoolUsage: 0x%08X\n"),
    pmc.QuotaPeakPagedPoolUsage );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("QuotaPagedPoolUsage: 0x%08X\n"),
    pmc.QuotaPagedPoolUsage );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("QuotaPeakNonPagedPoolUsage: 0x%08X\n"),
    pmc.QuotaPeakNonPagedPoolUsage );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("QuotaNonPagedPoolUsage: 0x%08X\n"),
    pmc.QuotaNonPagedPoolUsage );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("PagefileUsage: 0x%08X\n"), pmc.PagefileUsage );
    OutputDebugString(chBuf);

    wsprintf(chBuf,_T("PeakPagefileUsage: 0x%08X\n"),
    pmc.PeakPagefileUsage );
    OutputDebugString(chBuf);

    CloseHandle(hProcess);
