Why doesn't the commands to build openBR run? - c++

When I run the commands specified in OpenBR page to build the library, I am getting the following error. Its coming when I execute the sub module update command.
Is it because the the repository is not available in that location? If that's not the case, why is it not running?

(At first I think it should be a comment but I cant).
I have the same issue like you when I install it. I believe the problem here is the link to repos of doc of openbr(it's not correct, maybe it's changed). You can continue with build process, this error dont have any effect in it and use the doc from official website. Good luck!

MinGW can't be installed on Windows 10

I am trying to install MinGW but it's always failing to install. See the picture for the error message.
Error
Welcome to StackOverflow! My name is Alex and I will try my best to fix this problem of yours.
First, do you have a firewall running? Try running it as an Administrator.
If those didn't work, then I believe it's to the sourgeforge or the network itself. This is probably temporary and will be fixed so I suggest you try it later.
Good luck!
Since I cannot comment, I suppose there is no other way than write an answer. I am having the same issue and it seems to be related to the automated installer, it appears to be broken. Try installing manually (download the zip and manually place in correct directories and set system paths).

Datomic can't find Clojure.main

I've been learning Clojure for around a month now and I've decided to experiment with Datomic. I'm following the tutorial on the site exactly, but I can't even get past the first tutorial page (http://docs.datomic.com/first-db.html) because I get the following error on run:
run -m datomic.peer-server -p 8998 -a myaccesskey,mysecret -d firstdb,datomic:mem://firstdb
The system cannot find the path specified.
Error: Could not find or load main class clojure.main
I think this is just a classpath issue (I only picked up Java to work with Clojure), but looking at run.bat I think Datomic is set up to determine classpaths automatically, and I'd rather understand why it doesn't work out of the box (presumably a config issue on my machine, although I've tried another).
I've tried the latest version (0.9.5544) as well as the version explicitly mentioned in the tutorial (0.9.5530), as well as installing via Maven. Tried numerous other tutorials and forum-searches as well - plenty of general classpath advice, but nothing relevant to this. Please, send help!

Update - I seem to have resolved my issue. The instructions on the Datomic tutorial page appear to be incorrect (they say bin/run, but bin\run works). I worked around the bin/run error by running directly from the bin folder, but this obviously had the knock-on effect of making any relative paths incorrect.
I suspect I'm not great at Stack Exchange since I seem to have answered all of my own questions so far, but I hope someone else finds this useful!

Calling a OSX package from xcode c++ program terminal

im planning to build a c++ application based on another c++ package (aria2c) i found over the internet which acts as a ready made wheel for me. I have already installed the package on my machine, but the problem is when i run system("aria2c"); it outputs "command not found", whereas if i run system("git"); (which i have also installed) it will output the git's man page.
calling "brew" also doesnt work whereas git, ls and some other that i tried work.
So can someone explain to me why i cant access that package ? and if there is any solution to it ?
The most common mistake is that the pacakge might be installed for a particular user or at a particular path. Make sure that you have the library/application in your path list
To do that ,i would suggest first finding where the package is installed and then do echo $PATH in terminal to see if its in your path variable

PyQt-win-gpl-4.11.1 installation

I saw there was a previous question about installing PyQt on a Mac, but unfortunately I'm not quite able to comment on the thread so I had to post a new question. Like that user, I have been having issues downloading QT 4.11.1. I downloaded SIP as well as PyQT4 (link to instructions), but when I try to run python configure-ng.py from my downloads folder, I keep getting the same error saying:
Error: Use the --qmake argument to explicitly specify a working Qt qmake.
Unfortunately I can't find the Qt settings which means I can't keep following the directions from the previous answer and I was hoping someone might be able to help walk me through how to download this module. Sorry for the duplication and thanks in advance.

Subversion and DBUnit - How to download a specific snapshot version

I posted a question to the DBunit mailing list about an error I see when I compile my program. One of the response I get is shown below:
Please try 2.4.9-SNAPSHOT (you will have to build from source;
snapshots are not currently pre-built). I believe commit 1209 fixes
the problem you are experiencing:
I looked at the DBunit project and I can't figure out how to download this specific version.
I tried this command but it comes back with a Does not exist error
svn checkout https://dbunit.svn.sourceforge.net/svnroot/dbunit/trunc/2.4.9-SNAPSHOT dbunit
I think the command is correct because if I try a release that does exist it does work. For example the following command works
svn checkout https://dbunit.svn.sourceforge.net/svnroot/dbunit/tags/dbunit-2.4.8 dbunit
Looking at the online code browser I can't see an entry with the tag I want. See Example at http://dbunit.svn.sourceforge.net/viewvc/dbunit/
Does this mean that the 2.4.9-SNAPSHOT does not exist or am I doing it wrong?
Also, what does the SNAPSHOT label mean at the end of the release version? I have seen this used quite a lot but not really sure what it means.
Thanks
Just download the source code in specified revision:
$ svn co https://dbunit.svn.sourceforge.net/svnroot/dbunit/trunk dbunit -r 1209
$ cd dbunit
$ mvn clean install
The 2.4.9-SNAPSHOT version should appear in your repository when the build finishes. However I encounter some problems while building it, the com.oracle:ojdbc14:jar:10.2.0.4.0 cannot be found. Consult library developers how to fix this.
