You will need a 32-bit winearch. Typically your default .wine directory is 64-bit. Let’s leave that alone and create a new 32-bit wineprefix and setup Goldwave 5. (Goldwave 6 is not WINE compatible as of WINE 1.6).
Download Goldwave 5 to your ~/Downloads directory.
Then, from Terminal,
WINEPREFIX=~/.wine32 WINEARCH=win32 winetricks wmp10 WINEPREFIX=~/.wine32 wine ~/Downloads/gwave5*.exe
Once you’ve installed Goldwave 5, press the F11 key to open Control Properties, then select the System tab, and click the “Use DirectSound AP” radio button. You can test your setup by clicking the Device tab, and the Test playback button, you should hear a brief test tone. Click OK to save this setting.
You should be able to create new/save/play sound files (this gives Goldwave 5 a WINE Silver rating I think)
At this time, Goldwave 6 is not compatible with WINE that I know of. I get the following errors from Goldwave 6 after installing and trying to run Goldwave 6 in a 64-bit Windows 7 wineprefix:
err:module:import_dll Library BTHPROPS (which is needed by L"C:\\Program Files\\GoldWave\\GoldWave.exe") not found err:module:import_dll Library BLUETOOTHAPIS (which is needed by L"C:\\Program Files\\GoldWave\\GoldWave.exe") not found err:module:LdrInitializeThunk Main exe initialization for L"C:\\Program Files\\GoldWave\\GoldWave.exe" failed, status c0000135
This procedure is for OpenCV3 beta.
Some of the functions you might want like cv2.createBackgroundSubtractorGMG are not in the standard OpenCV 3 package at this time. The newer functions by design go into the opencv_contrib repository.
If you’re comfortable with the previous procedure, you might be ready to try adding these packages.
CRITICAL POINT: you must have the space between -D OPENCV_EXTRA_MODULES_PATH= for this to work, or it will silently ignore the opencv_contrib modules.
I will assume you have the prereqs installed already.
cmake command, scroll back up and check that you see something like (for example, look for bgsegm, that’s one of the opencv_contrib modules)

# the -j6 is for compilation only, to use up to 6 threads. It has no effect on the compiled opencv code execution make -j6 make install
Once installed, you should be able to from within Python type:
import cv2 x = cv2.bgsegm.createBackgroundSubtractorGMG()
I wanted to have access to OpenCV3 in Python3, so I compiled OpenCV3 for Anaconda Python3 as follows, using this reference.
I have not tried it, but I think that this would work for Python 2.7 as well by changing the python3 references to python2.
BE SURE when you type in Terminal
python3 that it’s the anaconda python you get. If not, make an alias in ~/.bash_aliases

NOTE: I assume you’re using an Ubuntu 14.04 system, within Anaconda Python 3.4 installed to ~/anaconda3/
Note: I have disabled Cuda via “-DWITH_CUDA=OFF”, assuming you don’t have a GPU to use. Because Cuda takes so much longer to compile, even if you have the GPU, maybe first try without CUDA, to see if OpenCV3 is going to work for you, then recompile with CUDA.
Note: To avoid the libopencv_imgcodecs.so.3.0.0: undefined reference to `TIFFOpen@LIBTIFF_4.0′ type errors, I added the -DBUILD_TIFF=ON option
Note: If you get the error like
lib/libm.so.6: version `GLIBC_2.15′ not found (required by /usr/lib/x86_64-linux-gnu/libx264.so.142)
mv libm.so.6 libm.so.6.bak
The standard Python indentation is four spaces, not tabs.
To make nano do this by default, add to your ~/.bash_aliases file the following:
<code>alias nano=”nano -c -ET4″</code>
where the -c is another option for having a row/column display.
Even if your system is 64-bit, you should use 32-bit Google Earth at this time.
On some installs, typing in terminal
gives the error
./googleearth-bin: error while loading shared libraries: libfontconfig.so.1: cannot open shared object file: No such file or directory
and libSM.so.6, etc.
This is remedied by typing:
sudo apt-get install libfontconfig1:i386 libX11-6:i386 libxrender1:i386 libxext6:i386 libsm6:i386
If you get errors about libGL.so.1, try:
sudo apt-get install libglu1-mesa:i386 libgl1-mesa-glx:i386
If you still get errors about libGL.so.1, try:
find /usr -name "libGL.so.1"
let’s assume you found it in /usr/lib/i386-linux-gnu/mesa
ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib
If you don’t have a graphical desktop, BU’s Enterprise Wifi requires the following manual settigns. The settings below are from BU’s recommended settings.
Their webpage has now been updated per my suggestion.
# nano /etc/wpa_supplicant/wpa_supplicant.conf
paste at the end

This results in the feedback upon successful connection:

The new plotting engine in Matlab R2014b has caused some hangups and reduced quality plots for people using Matlab over X11 forwarding.
Consider starting Matlab this way:
If you can’t start Matlab with the -nosoftwareopengl open, omit that open and try plotting with the
set(gcf….’painters’) line as shown above for each figure.
AGI STK (Systems Tool kit) does not currently run under WINE for version 10 of STK.
However, you can run STK from VirtualBox using Windows guest virtual machine.
Currently (with VirtualBox 4.3.16) you may find that STK crashes upon opening a scenario. Shutdown your virtual machine and try disabling 3D acceleration, enabling 2D acceleration, and setting video memory to at least 64MB. This “worked for me”
I save a script named “findtext” that will look for specific text you want inside any file smaller than a maximum size (avoiding searching huge binary file)
you can find this and several other useful scripts at
