I'm trying to build Python 3.8.3 using pyenv on Fedora 32: pyenv install 3.8.3. The error I'm getting is:
ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?
BUILD FAILED (Fedora 32 using python-build 1.2.21-1-g943015eb)
I want to point out however, that I don't have sudo permissions on the machine. I went through the common build problems, but I'm unable to fix the issue I'm facing. In addition, the OpenSSL lib is installed on the machine, i.e., which openssl outputs /usr/bin/openssl.
Any pointers?

I tried to install gfortran 10 from Fedora 31.
Follow https://fortran-lang.org/learn/os_setup/install_gfortran
sudo dnf install gcc-gfortran leads to gfortran 9
I tried to download from https://fedora.pkgs.org/33/fedora-x86_64/gcc-gfortran-10.2.1-3.fc33.x86_64.rpm.html
the download link file leads to Failed to install file, not supported from graphic interface :(
or bash: ./gcc-gfortran-10.2.1-9.fc33.x86_64.rpm: cannot execute binary file: Exec format error from terminal with root.
Is there any way to install gfortran-10 from Fedora?
Thanks!
You can of course always compile GCC from source, it is not that hard and the script for getting the prerequisites is included (./contrib/download_prerequisites).
The easiest way is to download one of the snapshots https://gcc.gnu.org/snapshots.html and follow the instructions. You do not even have to have admin rights, you can do it privately in your home directory.
Check whether there is a repository with additional GCC versions for your distro. For example, on my OpenSuSE, I have packages for GCC 7, 8, 9, 10 and 11. And they can be installed concurrently.
Regarding:
bash: ./gcc-gfortran-10.2.1-9.fc33.x86_64.rpm: cannot execute binary file: Exec format error
You cannot run a rpm file in bash, you have to install it using rpm -i or using your higher level package manager.
The file you downloaded is an RPM package, not an executable. You would normally install it with dnf install ./gcc-gfortran-10.2.1-9.fc33.x86_64.rpm from the command line. However, that package is for Fedora Linux 33, and you're running 31. Occasionally this works, but generally installing packages from new releases on older releases isn't supported.
If, for some reason you can't upgrade to Fedora Linux 33 for your whole system, one approach is to use the toolbox utility to make a containerized workspace using a F33 container image. Then, you can install the version of gfortran you want into that (with dnf install gcc-gfortran).
You could also use F34 (out tomorrow) but note that that has gcc 11.
On older versions of Fedora, one could run the following command to install the rpm-python package:
$ sudo dnf install rpm-python
But now on Fedora 32, it gives the following error:
No match for argument: rpm-python Error: Unable to find a match:
rpm-python
Which package should one install now to get that same package or a similar one on their machine?
Fedora 31 has packages python2-rpm and python3-rpm. The package rpm-python does not exist for a long time. You can request installation of rpm-python, but DNF will actually install python2-rpm.
Fedora 32 moved to Python3 completely (there are some rare exceptions) and python2-rpm ceased to exists. There is only python3-rpm which has the same code. The same API. It is just for python3 only.
I'm trying to demo rust database program using diesel.rs library.
I'm following the getting started steps here.
As mentioned in this page, I got below error while running the command cargo install diesel_cli.
note: ld: library not found for -lmysqlclient
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The solution is given in the next step as well in same page as below.
You can resolve this issue by either installing the library (using the usual way to do this depending on your operating system) or by specifying the backends you want to install the CLI tool with.
But I don't know how to do this in my mac OS. I tried the below commands.
brew install mysqlclient
brew install lmysqlclient
But brew couldn't find any such repo.
Please help me how to resolve this error and install mysqlclient library in my mac OS.
mysql-connector-c seems to be the homebrew package you are looking for. Libmysqlclient should also be installed when installing the mysql brew package.
I have spent hours trying multiple approaches to install MYSQLDB module for python, and no success.
My python version: 2.7.6
Django - 1.10.3
OS: Windows 7 64-bit
MySQL connector - MySQL Connector C 6.0.2
Currently I have an error in my project, namely:
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb
I have tried to install mysqldb running the following command:
pip install mysql-python
It ran successfully, but the error still persisted. Then I tried to run
pip install MySQL-python
and I am getting Cannot open include file config-win.h.
I came across this post, but I don't understand the idea of the answer, specifically, I can't figure out where I should look for the mentioned files site.cfg and setup_windows.py. There are no such files in C:\Program Files\MySQL\MySQL Connector C 6.0.2\include
Finally, I tried to install MySQLDb using wheels running
pip install mysqlclient-1.3.9-cp27-cp27m-win_amd64.whl command, I end up with
mysqlclient-1.3.9-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform error.
I have lost my hope. Help please !!!
Try to install 32 bit version mysqlclient-1.3.9-cp27-cp27m-win32.whl
If it doesn't work try to install it from (where you can find compiled windows libraries):

I installed latest Octave on Ubuntu 14.04 machine. However, when I tried to run imread command, it showed the following error message:
octave:12> imread('newfile.png')

Can someone please suggest how to solve it?
Thanks!
Following these steps worked for me [Author: Christoffer Cronström (hymyly)]:
Install the dev packages needed to build octave.
sudo apt-get build-dep octave
Get the official source package. Do this in a clean directory, because it will get polluted.
cd ~/some/suitable/directory
apt-get source octave
Build it. This took roughly an hour for me.
cd octave-3.8.2
dpkg-buildpackage
Either run it from the build directory:
./run-octave
...or most preferably install it over the official octave:
cd ..
sudo dpkg --install octave_3.8.2-4_amd64.deb

How did you instal Octave? The error suggests that you're missing GraphicsMagick C++ interface (package libgraphicsmagick++3) but
if you installed Octave from Ubuntu's package manager you should not have had this problem; * if you compiled it yourself, Octave should have disabled imread completely and you'd have a very different error message.
So my guess is that you build it yourself, either with:
your own build of GraphicsMagick++ which are not being loaded anymore, you may need to add their path to the dynamic linker load path (either on /etc/ld.so.conf.d./graphicsmagick or define LD_LIBRARY_PATH);
the libraries from the package manager which you have since accidentally removed (since you did not install Octave from the repositories, your package manager will not know that libgraphicsmagick++ is installed for a reason).
Either way, the solution is easy. Install Octave from Ubuntu's package manager. One of the main reasons package managers exist is to avoid this type of problems, i.e., missing dependencies.
