I'm trying to install Octave 4 from source code in CentOS 7 but I got the warning messages:
configure: WARNING: OpenGL libs (GL and GLU) not found. Native graphics will be disabled.

I have checked this QUESTION but it didn't help.
I have also done yum install libqt4-opengl-dev but got an error No package libqt4-opengl-dev available.
I have got mesa-libGL and mesa-libGL-devel, but it seems like the configure cannot pick up these libraries.
Edit: answer to my own question
please see comments below the question.
I know that it's an old question, but I wanted to leave it in case if someone is still looking for an easy way of installing Octave 4.x.
The easiest way to install Octave 4 is to use Flatpack. It's installed by default in CentOS 7.
flatpak install flathub org.octave.Octave
flatpak run org.octave.Octave
If you're using Red Hat you need to install flatpak it first:
sudo yum install flatpak
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

I try to compile Emacs 26.2 on Centos 7. So I run
./configure
But the script complains:
configure: error: The following required libraries were not found:
gnutls
Maybe some development libraries/packages are missing?
However yum tells me that gnutls is already installed:
Package gnutls-3.3.29-9.el7_6.x86_64 already installed and latest version
What else do I miss to compile Emacs with gnutls support?
Try installing the package gnutls-devel. While the gnutls package contains the files needed to run a program that uses GnuTLS, gnutls-devel is needed to compile a program using GnuTLS.
When trying to install any package on my computer using a command like
cabal install http-conduit
the installation aborts with the following error:
/usr/bin/ld: --hash-size=31: unknown option
How can I resolve this?
Note: This question intentionally doesn't show research effort, because it was answered immediately in a Q&A-Style manner.
This issue occurs with the binutils-gold package and GHC 7.4. There is an old mailing list entry discussing this issue.
You might need binutils-gold for LLVM for example, but GHC 7.4 can't handle the GOLD linker correctly, because it doesn't understand the --hash-size option.
As noted on the mailing list post, the solution to this is to remove binutils-gold, e.g. on Ubuntu use:
sudo apt-get remove binutils-gold
This will re-symlink /usr/bin/ld to a non-GOLD linker version. After that, repeat the cabal install command.
I have encountered a problem installing Pango-1.30 on a Ubuntu 12.04 platform. During ./configure step I receive a message saying "Could not enable any of Freetype, X11, Cairo, or Win32 backends. Must have at least one backend to build Pango". However, I have build and installed Freetype and X11 and they are located in /usr/bin. How do I inform ./configure where to get them?
Thanks,

Ensure you have all the dependencies installed, you can find them in the README file.
They are:
fontconfig

I am trying to use mexopencv on my system which has:
Ubuntu 12.04.1 LTS
opencv 2.4.2
gcc-4.4
matlab 2012
and they all are working. I also used some c++ codes to test mex and it worked fine.
I used this to install mexopencv. Also did this because of some error I got which mentioned libstdc++.so.6
Now when I try something like:
a = cv.imread('pic.jpg');
I get:
Error using cv.imread
Invalid MEX-file '/home/primepc09/mexopencv/+cv/imread.mexa64': /usr/local/lib/libopencv_highgui.so.2.4:
undefined symbol: _ZNK9QCheckBox15minimumSizeHintEv
Any idea why I get this?
This is an unresolved symbol from QT library. Make sure you have QT installed on your system:
sudo dpkg -l | grep libqt
If you don't have it, you need to install it.
I'm trying to install GTK-DFB and cairo is a requirement. When I try to build it from source, it throws:
checking for cairo's PNG functions feature...
configure: WARNING: Could not find libpng in the pkg-config search path
checking whether cairo's PNG functions feature could be enabled... no
configure: error: recommended PNG functions feature could not be enabled
Ideas?
Thanks
For me it helped to export the following variable in the shell:
export png_REQUIRES="libpng"

You need to have the libpng development packages installed; Installation is distribution dependent, but for debian derivatives following should be enough:
apt-get install libpng12-dev
If you're on Ubuntu, another much faster solution is to do:
apt-get build-dep gtk+2.0
