Rename the dir to testlink (Optional, just affect the URL)

3. Install MySQL,PHP5, and related mod
sudo apt-get install mysql-server php5 php5-mysql php5-gd

sudo vim /etc/apache2/httpd.conf
Add:
AddType application/x-httpd-php .php .htm .html
AddDefaultCharset UTF-8
ServerName 127.0.0.1
Restart apache server
sudo /etc/init.d/apache2 restart

5. Install with web installer.
http://your_ip/testlink
Just follow the instructions.

6. Finish the installation
Reload the page again and login as admin (pwd = admin)
Change admin's passwd in "Personal" page
Remove install/ in var/www/testlink
Edit config
sudo vim /var/www/testlink/config.inc.php
Turn off the warning message:

OpenCORE Debug Print on Android

To utilize the existing log statements without rebuilding the whole PV library, you can do this:
1. In the beginning of the file, after the last "#include" line, add following:
#include <utils/Log.h>
#undef LOG_TAG
#define LOG_TAG "YOUR_MODULE_NAME"
#undef PVLOGGER_LOGMSG
#define PVLOGGER_LOGMSG(IL, LOGGER, LEVEL, MESSAGE) JJLOGE MESSAGE
#define JJLOGE(id, ...) LOGE(__VA_ARGS__)


2. In the end of the file, add these:

#undef PVLOGGER_LOGMSG
#define PVLOGGER_LOGMSG(IL, LOGGER, LEVEL, MESSAGE) OSCL_UNUSED_ARG(LOGGER);


You can play with the macro to filter based on level too.
