I installed the latest (2021-01-05) version of MinGW https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/installer/mingw-w64-install.exe/download.
It installed, but I can't find mingw-get, so I don't know how to update it. I also can't find make or bash (or rm).
How can I interact with the new version of MinGW?
I don't think this is a good way to have a updatable MinGW environment.
For that, I would recommend using MSYS2, where within the msys2 shell you can get MINGW packages using the pacman package manager.
Here you have the mingw-w64 package list. (It is quite extensive - I'm using pastebin for that reason)
First Edit
After installing MSYS2 you need to add a path C:\msys64\usr\bin to your $PATH.
You could add it via cmd.exe like:
setx PATH "%PATH%;c:\msys64\usr\bin"
If you need to gdb you could use scoop which is a package manager for windows. I'm using it regularly:
PS C:\Users\user> scoop search gdb
'main' bucket:
avr-gcc (10.2.0) --> includes 'avr-gdb.exe'
gdb (9.1-3)
PS C:\Users\user> scoop search MinGW
'extras' bucket:
codeblocks-mingw (20.03)
'main' bucket:
gcc (9.3.0-2) --> includes 'mingw32-make.exe'
msys2 (2021-01-05) --> includes 'mingw'
openssl-mingw (1.1.1i_2)
'versions' bucket:
msys2-20200517 (2020-05-17) --> includes 'mingw'
Again you need to enhance your path. I like to have the MSYS2 in the C:\ so I usually create:
cmd /c mklink /D C:\MSYS64 C:\app_scoop\apps\msys2\current
The instructions are for you.
For your students I would recommend creating a portable package which would include all necessary stuff. They would need to unpack it only.

While installing saleor, I have encountered with the below issue.
OSError: cannot load library 'gobject-2.0-0': error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library called 'gobject-2.0-0'
I have tried all the solutions given in stack overflow as well as git. Nothing seems to be working.
Can someone please help me out.
Tools installed:
python: 3.8 / 3.9
GTK3
I have also updated the GTK3\bin in the top of the environment variables as said in the other solutions.
Download the https://www.msys2.org/ and install it.
a) install gtk package and python bundles from MSYS2 terminal. We can start this with command shell. and pacman -S mingw-w64-x86_64-gtk3
b) pacman -S mingw-w64-x86_64-python-gobject
Update your $XDG_DATA_HOME and XDG_DATA_DIRS to the installed path for example :
'C:/msys64/mingw64/share'
Reboot your system and check, it will work.
Another option that worked for me is :
Install MSYS2 from https://www.msys2.org.
Install GTK3 DLL Dependencies from here : https://github.com/tschoonj/GTK-for-Windows-Runtime-Environment-Installer/releases
And then set environment path variables to your windows variable path file.

I followed this guide and installed emscripten using emsdk and activated it.Then I configured my $PATH as instructed by the emsdk itself and also sourced emsdk-master/emsdk_env.sh.Now I can access both emcc and em++ in the terminal.The file ~/.emscripten is also present(this is the file that QtCreator will fetch to find the path of compilers for WASM).
The WebAssembly kit for Qt also has been installed by the Qt Maintenance Tool.
Now in the Kit configuration in the QtCreator I get this(QtCreator is opened via terminal after sourcing emsdk_env.sh):
It cannot determine the path of compilers by itself.
In the Compilers tab I manually added a compiler as follows:
But I get this error in the Kits tab after that:
What does that mean? What did I skip? Does anybody ever have the experience of doing this?
Also changing the compiler from em++ to wasm-32-wasi-clang++ or clang++ doesn't change anything.
By the way if I use that kit I get:
Error while parsing file whatever.pro. Giving up.
Project ERROR: Cannot run target compiler 'em++'. Output:
===================
===================
Maybe you forgot to setup the environment?
And please don't tell me that this question is the duplicate of this because it isn't(mine has more details) and there's no useful answer for that after 9 months at this time.
Any help is much appreciated.
Make sure you run:
emsdk install
and
emsdk activate
within emsdk folder, not from a relative path.
You have to setup the emsdk inside QtCreator => Preferences => Devices => WebAssembly. Afterwards the compiler should be auto-detected by Qt Creator.
I had the same problem and the solution was, that python was not correctly recognized.
In my case the symbolic link /usr/bin/python was not set
ln -sf /usr/bin/python3 /usr/bin/python
Afterwards the emsripten Toolchain is recognized automatically in QtCreator.
Hi I have QtInstalled with the official qt installer (I haven't used the package with the name "qtcreator").
I need to run QtCreator from terminal but I can't locate the executable.
I'm using Ubuntu 16.04.
Probably you can find the executable in opt directory the location will be as this /opt/Qt/Tools/QtCreator/bin and you can run it through terminal as ./qtcreator
Latest QtCreator should by default be installed in
${HOME}/Qt/Tools/QtCreator/bin/
And you have two start-up options, the executable qtcreator or the shell script qtcreator.sh
To run the executable, type
~/Qt/Tools/QtCreator/bin/qtcreator
To run the shell script, type
~/Qt/Tools/QtCreator/bin/qtcreator.sh
Whic one to use: From the top portion of qtcreator.sh, it states that if you have library name conflicts (such as having same library names used by qtcreator with your own LD_LIBRARY_PATH), you may want to start with the shell script, rather than the bare executable.
Windows linux subsystem users
In case you have ubuntu as a subsystem for win10, it's located in your AppData folder (installing with sudo apt install command):
Also, you cannot run qtcreator from terminal as graphical interface is not supported by defeault. You need to instal X-server app first (https://sourceforge.net/projects/xming/) and then you can run QT from terminal.
C:\Users\[YOUR_USERNAME]\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs\usr\share\qtcreator
Or, it's in usr/lintian/overrides
But you should not modify anything inside this linux root, as it may lead to data loss.
For me it wasn't in the /opt directory, but rather the location I've chosen in the /home/user/ directory.
More specifically: /home/user/Qt5.12.1/Tools/QtCreator/bin/qtcreator
I got a source code from github. It writen by Qt, and I have installed the Qt from the Qt official website. But when I run ./configure. It said error: cannot find QtGui. What can I do? I don't want to install duplicated through the apt-get. I set the LD_LIBRARY_PATH in .zshrc. It's not work.
The usual way is to install dependencies through apt-get. If you install them manually, you need to resolve path issues by your own.
Since you've chosen the dark path, now you need to manually inform configure where your QT include files and libraries are located:
export CPPFLAGS='-I/qt/path/include'
export LDFLAGS='-L/qt/path/lib/'
./configure
One-liner:
env CPPFLAGS='-I/qt/path/include' LDFLAGS='-L/qt/path/lib/' ./configure

I am trying to install Code::Blocks 10.05 from (non-SVN) sources (codeblocks-10.05-src.tar.bz2). My OS is Ubuntu 11.04. I needed to download and install wxWidgets first (I now have wxGTK-2.8.12), which seemed to work. I compiled it according to these instructions:
http://wiki.codeblocks.org/index.php?title=Installing_Code::Blocks_from_source_on_Linux
Then I configured C::B with
./configure --with-wx-config=/opt/wx/2.8/bin/wx-config
and ran
export LDFLAGS="-Wl,-R /opt/wx/2.8/lib"
make
sudo -i
make install
When trying to run C::B, I get the following error:
codeblocks: error while loading shared libraries: libwx_gtk2u-2.8.so.0: cannot open shared object file: No such file or directory
The same question was asked here: error while loading shared libraries, but the suggested solution (namely adding the wxWidgets config to the options passed to configure) didn't work for me.
The output of wx-config --prefix is /opt/wx/2.8,
The output of wx-config --libs is -L/opt/wx/2.8/lib -pthread -lwx_gtk2u-2.8,
and that of which wx-config is /opt/wx/2.8/bin/wx-config.
I looked for the library and found /opt/wx/lib/libwx_gtk2u-2.8.so.0 to be a link to libwx_gtk2u-2.8.so.0.8.0 in the same folder.
What might be wrong here?
The problem is that the program cannot find the WX widgets libraries at run time. You will need to set your LD_LIBRARY_PATH variable to include the location of wxWidgets like this:
LD_LIBRARY_PATH=/opt/wx/2.8/lib ./codeblocks
The reason why its failing is because you compiled codeblocks against wxWidgets found in /opt/ and not the one installed in /usr/; the program doesn't know to look in /opt for the wx libraries.
Probably the easiest way to get code::blocks up and running on Ubuntu is to just install it via the Synaptic Package Manager. Just type in codeblocks into 'Quick search'. Find codeblocks on the list and just right-click to mark for install. Any dependencies and missing libraries needed will automatically be handled and installed by Synaptic as necessary.
If you're interested in trying the C::B nightly builds on Ubuntu then you'll want to checkout Jens' unofficial debian-repository here.
You can visit Why do I have to define LD_LIBRARY_PATH with an export every time I run my application? for a more generic case. For a particular case like yours you can follow the below given steps
If you had installed wxGTK then you would see the file in /usr/local/lib. You would get this error when the the above path is not as part of the makefile. I received this error while starting wxFormBuilder after building from source on CentOS. There are 2 approaches.
Approach 1: Putting the path in .bashrc
gedit /home/{your-username}/.bashrc
Then after the line # User specific aliases and functions paste the following
export $LD_LIBRARY_PATH=/usr/local/lib.
This would work for fine but for the current login, but for other users like root you might have to do the same in the respective .bashrc files.
Approach 2: Creating your own conf files
cd /etc/ld.so.conf.d
gedit wxformbuilder.conf
Give the path /usr/local/lib and save the file.
ldconfig (To update the library path).
