Output Debug String

As we know, we can use API OutputDebugString to show string on output window, like,

OutputDebugString(" This is debug message. ");
OutputDebugStringW(L" This is debug message. ");

You also can attach some variable to the output string.

wchar_t* world = L"world";
wchar_t* szBuffer = new wchar_t[512];
wsprintf(szBuffer, _T(" Hello %s \n"),  world);
OutputDebugString(szBuffer);
delete[] szBuffer;

or

wchar_t* message = L"world !";

wchar_t* str = L" Hello ";
wchar_t* buffer = new wchar_t[sizeof(str)+sizeof(message)+1];
wcscpy(buffer, str);
wcscat(buffer, message);
OutputDebugStringW(buffer);


or

float value = 100;
wchar_t* szBuffer = new wchar_t[512];
wsprintf(szBuffer, L" My math grade is %d \n",   (int)value);
OutputDebugString(szBuffer);
delete[] szBuffer;

or

float value = 100;
char* szBuffer = new char[512];
sprintf(szBuffer, L" My math grade is %f \n",  value);
OutputDebugStringA(szBuffer);
delete[] szBuffer;

[Platform Builder] Output Logging Message to File

As we all know, there are lots of useful message shown in output window.
The window doesn't has huge buffer to keep all of messages.

We can try to output it to file and check it later.
Click Target->Debug Message Options->Check Send to file and specify file path

  * After you save the file, execute following command.
    $ sudo chmod a+r /etc/udev/rules.d/51-android.rules

8. Setting up ccache
$ export USE_CCACHE=1


Download source  ============
1. Create a bin/ directory in home directory and make it included in path.
$ mkdir ~/bin
$ PATH=~/bin:$PATH

2. Download the Repo script
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

3. Create a working directory, the name is up to you.
$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY

4. Run repo init
$ repo init -u https://android.googlesource.com/platform/manifest

5. Check out branch
$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.1.2_r1

6. Start to download
$ repo sync

7. Verifying Git Tags, I don't know what the step for.
$ gpg --import

Solution:
Open file in  
external/smali/smali/Android.mk
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.)

Change it to:
    if not terminator.rstrip() == "@end"

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.
