I've been given a Matlab program that uses an external C function. I only have the compiled version of this external function, and the extension is .mexglx . From what I have already red, it seems that this extension is the mex-file version compiled with linux. I run matlab under windows XP, and my problem is that my Matlab is not able to read the .mexglx extension. So my question is: is there any mean to change a file with the .mexglx extension to a .mex? Because for the moment I do not have the source code in C, so I can't recompile it correctly. I precise that my version of Matlab is R2007b if it can help.
Thank you for your answer
No there is no way, sorry. You need to get the source code to build it for a different platform.

Python : 3.5
PYinstaller : 3.5
Win64
cx_Freeze : 6.0
According to the above information, I have tried to convert Python project to exe but it does not work.
First I have tried pyinstaller but the process throw some error:
After that, I have tried cx_Freeze and it works, but the exe are working on some computer but not on every computer that have same platform.
I don't know what I can do. I looked for google and stackoverflow but there are unsolved problems or I couldn't see the solution.
Later I have tried to change python version but doesn't work again. Computers that have tried to running the exe, have same OS platform, I'm sure.
By the way, if you receive the following cx_Freeze error, resolving like this:
Build\exe.win-amd64-3.7\lib\scipy\spatial\cKDTree.cp37-win_amd64
change to
Build\exe.win-amd64-3.7\lib\scipy\spatial\ckdtree.cp37-win_amd64
Program uses the following modules : tkinter, pydicom, skimage, PIL, cv2, etc.
Primarily Program has 2 page that content code but I made single file for I came across this sentence "It's worth noting that pyinstaller can compile to a single .exe file"
What do you suggest I do? Thanks for your help.
Edit: I have been tried "Auto-py-to-exe" but I got an error (Fatal Error : Failed to execute script")
Edit2: I tried to run outside the anaconda. I think its work. But I'm still testing.
Edit3: I have tried to change python version, GUI was opened another computer but the program is not work properly. the program works on my computer but not on another computers
If you are not able to convert python file to executable format, you can try using auto py-to-exe library.
This library contains a GUI format to convert .py files to .exe
Here you can find auto py-to-exe with usage instructions,

I am new to python and need to compile it into .exe version. My question is when a py script is compiled into .exe does it mean it cant decode anymore?
Our goal is make python scripts safe when deploying to client servers as we dont want them to get our source code using the .exe.
No - a compiled piece of code is compiled into another language (byte code) - you can not actually read the source code.
Do have a look at this though...
A savvy user who has this .exe version could extract the .pyc (byte code) and then break that down using a python decompiler like Uncompyle to get it pretty much back to source code. Thus there is a way (and a chance) of the python source code (close to it) getting extracting from your .exe version.
I'm trying to set up a vehicle detection system from the LSVM code here: https://github.com/rbgirshick/voc-dpm
I'm using Red Hat Linux with Matlab 2011a.
I've unpacked the above system's files and opened Matlab. I select the whole directory where I unpacked the files, and all the subdirectories in it and right-click and do "Add to Path".
Then I right-click on compile.m in Matlab and then hit Run.
But I get the following error:
mex: fv_cache/fv_cache.cc not a normal file or does not exist.
Warning: Maybe you need to call fv_cache('unlock') first?
Does anyone have any idea of how to go about fixing this?
I tried calling fv_cache('unlock') in different places in the compile file, but to no avail. I'm not really experienced with Matlab and the whole mex thing.
This may because the fv_cache.cc not compiled correctly. My solution is using $ mex -DMX_COMPAT_32 $ when compile on a 64-bit machine.
I know I can use ResHacker to change a resource from windows and I know I can use ResourceUpdate function to do the same problematically (again in windows). My problem is that I have to update the icon of a windows exe file in linux, without using wine.
(the reason for not using wine is that this process should run on an automation server that change the files and sign them).
I don't know even where to start from.
You can change a files metadata like this:
gvfs-set-attribute '/path/to/file' -t stringv metadata::custom-icon "/path/to/image.png"
There's a program called windres that should suit your needs
Whoops, that's just a resource compiler, sorry.
However there is pefile a python module for working with PE executables, perhaps you could write a script with it that does what you want
I am having problem with implementing LibSVM to MATLAB.
I am using MATLAB R2009a (I also have the latest version, R2012b, but I dont use that one)
I downloaded LibSVM package, libsvm-3.14 to my Windows 7 PC, which MATLAB and OCTAVE interface come together.
I extracted the folder I downloaded. Which, below, you can see the printscreen of what the folder has in.
Where should I put my libsvm-3.14 extracted folder ? Should I put it under "bin" folder of my MATLAB installed in the directory?
C:\Program Files\MATLAB\R2009a\bin
I did that, however, it didn't work out. I will be grateful if you help me clearly. I just read README file, but it's not clear to understand and there is no other instructions online on the internet.
For the time being, it does not matter where you put that folder. You'll have to compile the Matlab-MEX files, from the source code that resides in the matlab subfolder of your extracted libsvm package.
Below, I will call the libsvm-3.14 (for example: C:\libsvm-3.14) extracted folder ROOT (so replace ROOT wilth C:\libsvm-3.14 below).
So, fire up Matlab and, then, at its command prompt, type:
cd ROOT
cd matlab
make
Now, in the ROOT/matlab folder, you should have obtained two MEX files (with the .mexw32 or .mexw64 extension). These are the files that you will use from now on. You can discard the rest, except those files (and, maybe, some other generated libraries).
According to the Makefile (that is ROOT/matlab/make.m), the MEX files are called svmtrain and svmpredic (+ the extension).
So, next step would be to create a subfolder called libsvm/ under your's Matlab/toolbox folder, copy the two MEX files therein and, then, add that libsvm/ folder to the Matlab Path (not the Path of your system, but of your Matlab installation).
Then, by typing:
svmtrain
and
svmpredict
you should have the help (usage) of these two functions.
With the aid of #axeoth, here is the solution. I followed instruction files in matlab subfolder of extracted libsvm package. I downloaded and installed Microsoft Visual Studio 2010 and wrote 'mex -setup' on command window of MATLAB to choose a suitable compiler for mex (I use MATLAB R2012b in 32-bit PC, so I found supported compilers in this link http://www.mathworks.com/support/compilers/R2012b/win64.html) After then, I followed #axeoth's instructions. I changed the name of the folder to ROOT and moved it to Documents/MATLAB. I started MATLAB and on command window, I wrote these below "one by one"
>> cd C:\Users\HUstat\Documents\MATLAB\ROOT\matlab
>> cd matlab
>> make
then I copied everything obtained in ROOT/matlab subfolder. I created a new folder named libsvm under MATLAB/toolbox folder and pasted everything there. and then, I added that libsvm/ folder to the Matlab Path by using "Set Path" button on MATLAB R2012b. After then I wrote "svmtrain" and "svmpredict" so I got the helps of these two commands.
For those having major compiler problems I thought I'd leave some extra information on the subject of installing compilers. This was a frustrating problem I had an ended up contacted MATLAB for help. I would have commented in the above posts but I do not have enough "rep" so here it is:
I was unable to install Microsoft Windows SDK 7.1, whether via Microsoft Visual Studio 2010 or otherwise. I found out that this was because I had a certain version of Microsoft Visual installed (version 10.0.04... was the cause of the problem for me). The work around was to uninstall Visual, install SDK 7.1 independently and then re-install Visual after. The process is written up in greater detail in the link below:
http://www.mathworks.com/matlabcentral/answers/95039-why-does-the-sdk-7-1-installation-fail-with-an-installation-failed-message-on-my-windows-system
It may also be that you have the compiler installed but that it wasn't recognised until MATLAB "found" it. This happened to me after the re-install. To check if you have the correct compiler and "find" it run mex.getCompilerConfigurations('Any','Installed') to get a full list. Then do mex -setup using the SDK 7.1 choosing the C/C++ version over FORTRAN.
I know the question is answered already but hopefully this may help someone the same predicament I had.
