MemoryAnalyzer/WSL

Windows Subsystem for Linux

it is possible to test Linux builds on a Windows 10 (or 11) machine using Windows Subsystem for Linux.

Install WSL2 with for example Ubuntu or Ubuntu 20

For Windows 10: Install Cygwin and X-Server

For Windows 11: X-Server is installed on WSL2 by default

For Windows 10: Install the appropriate graphics driver: Microsoft WSL GUI apps

For Windows 11: Graphics driver is installed on WSL2 by default

Install unzip

sudo apt install unzip

Install GTK:

sudo apt-get install libswt-gtk-4-jni libswt-gtk-4-java

Install WebKit:

Eclipse instructions sudo apt-get install libwebkit2gtk-4.0-37

Install Java 17 or later

sudo apt install openjdk-17-jre-headless

For Windows 10, start the X-server: Find the IP address of the WSL2 system: ip addr | grep eth0

From Cygwin64 command prompt. xhost should have the IP address of the WSL2 system as seen from Windows / Cygwin

startxwin -- -listen tcp
xhost +127.0.0.1 #Add the appropriate IP address, need to check for WSL2
# xhost +172.22.46.35 # or use this for WSL2, replace the address with the address from ip addr above
# xhost +$(wsl hostname -I) # or use this from a Cygwin xterm window to automatically find the WSL2 address

Download Memory Analyzer zip

unzip MemoryAnalyzer-1.12.0.20210602-linux.gtk.x86_64.zip

For WSL1

cd mat
export DISPLAY=:0
./MemoryAnalyzer

or for WSL2, Windows 10

cd mat
export DISPLAY=$(ip route | grep default | cut -d ' ' -f 3)':0' # Finds the IP address of the Windows machine
./MemoryAnalyzer

or for WSL2, Windows 11 ./MemoryAnalyzer

Problems

Problem: Failed to load swt-pi3

 ./MemoryAnalyzer
SWT OS.java Error: Failed to load swt-pi3, loading swt-pi4 as fallback.
MemoryAnalyzer:
An error has occurred. See the log file
/home/user1/mat/configuration/1689022953567.log.

Solution:

Install GTK4

Problem: Failed to create a browser

 Failed to create a browser because of: No more handles because there is no underlying browser available.
Please ensure that WebKit with its GTK 3.x/4.x bindings is installed.
Consult error log for more details.
Press F1 or the help icon for help.

Solution:

Install WebKit

Charts

To get charts working, add -Djava.awt.headless=true to `MemoryAnalyzer.ini` in the vmargs section.

WebKit problems - e.g. Ubuntu 22.04

If you get errors such as the following, and blank pages for reports or help:

 (WebKitWebProcess:22883): Gdk-ERROR **: 12:42:02.853: The program 'WebKitWebProcess' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadFBConfig'.
  (Details: serial 148 error_code 161 request_code 148 (GLX) minor_code 21)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

try starting Memory Analyzer like this WEBKIT_DISABLE_COMPOSITING_MODE=1 ./MemoryAnalyzer
