I have problem with installing dlib. Im using debian 7 and python 2.7. Thats the full code.
Im following the steps from these guide - https://www.pyimagesearch.com/2017/03/27/how-to-install-dlib/
Full log you can find here - https://paste.ee/p/AbXxJ
GCC 4.7 is too old. You need a C++11 compiler. Get a newer version of GCC.

I am trying to build open embedded project. But it shows some error like
/usr/lib/x86_64-linux-gnu/libstdc++.so.6: GLIBCXX_3.4.26 not found
How can i install GLIBCXX_3.4.26 in Ubuntu 16.04 ?
I believe the object you are trying to use was compiled with a fairly recent version of GCC 9 with this bug fixed. This GCC version has not yet been released.
You need to recompile it with the Ubuntu system compiler, or ask the Ubuntu compiler people to backport this fix into the Ubuntu 16.04 system compiler (which seems fairly unlikely to happen at this point).
I solved the problem by 2 steps:
1 Install a Anaconda3
2 Copy the file libstdc++.so.6.0.26 to path '/usr/lib/x86_64-linux-gnu', then create a soft link.
I worte the detail commands here.
So I have been trying to install the graph-tool module on my Ubuntu system all day now. I just cant seem to figure it out. Basically I want to use the package in jupyter notebook (in an anaconda enviroment). I followed several installation instructions, but nothing seems to work.
This for example: https://gist.github.com/dlozeve/ed59bba8bc8cb9b21e2af36cc9766938
I get to the configuration (adjusting for the fact that I am using python2.7),
./configure --prefix=/home/timo/anaconda2/envs/graph/ --with-python-module-path=/usr/local/lib/python2.7/site-packages
yielding:
configure: error: *** A compiler with support for C++14 language features is required.
Does anyone know what I might be doing wrong? Or as a simpler way to get graph-tool to work in my jupyter notebook?
Thank you very much!
The configure script is telling you exactly what is wrong: You need a compiler with C++14 support. This just means that your GCC is too old.
(You haven't told us any pertinent detail, such as the compiler version you have, library versions, etc, so we can only guess. But luckily, the configure diagnostics is crystal clear.)
A simpler way to install graph-tool would be for you to upgrade your distro (14.04 is outdated) and use the Ubuntu packages, as described here: https://git.skewed.de/count0/graph-tool/wikis/installation-instructions#debian-ubuntu
As graph-tool does not seems to run in an anaconda environment and Ubuntu 14.04 does not have support the latest C++ compiler that is needed, I did install Ubuntu 16.04 and followed firstly [https://www.google.de/amp/s/www.rosehosting.com/blog/how-to-install-jupyter-on-an-ubuntu-16-04-vps/amp/] and then finally installed graph-tool as described on the homepage.
This way I get to use jupyter notebook and am still able to import graph-tool.
Have anyone tried installing Shogun on CentOS? Will it work? I tried downloading the source from Shogun site and compile it and it wasn't that easy(also, installed all the requirements needed for shogun). Is it possible to install on CentOS?
yes, shogun is being built on a CentOS7 after each commit.
you can learn about the cmake parameters and how it works from here:
http://buildbot.shogun-toolbox.org/builders/CentOS7%20-%20libshogun
I think this is a bug of shogun, which does not compile with gcc 4.8.5 on CentOS7. This bug will be be fixed until shogun 6.2.0. see here
I'm tearing my hair out trying to compile c though Python's distutils. Specifically I'm trying to get started with Cython following this guide: http://docs.cython.org/src/quickstart/build.html, using a setup.py.
I'm running Python 3.5.0 under Anaconda 2.4.0 (64-bit), Windows 7.
I get the Unable to find vcvarsall.bat error referred to here: Cannot find vcvarsall.bat when running a Python script and in various other questions.
None of the proposed solutions work for me. So far I have tried:
installing Visual Studio - I have all versions from 2008 to 2013, ie 9.0, 10.0, 11.0, and 12.0.
pointing environment variables (VS100COMNTOOLS etc) related to the above directly to the correct locations
installing Microsoft Visual C++ Compiler for Python (as above link). This seemed to work but I get a compilation error that seems to be an incompatibility; I think because the compiler is intended for Python 2.7.
Ravi Kumar's suggestion at the above link to update pip's setuptools. Pip gave me an error saying it couldn't update.
Installing MS Windows SDK for Windows 7 and .NET Framework 4 as https://github.com/cython/cython/wiki/CythonExtensionsOnWindows. The final step failed with an error message that the x64 compilers aren't currently installed.
The only thing I can think of is installing MinGW which I've seen suggested in some places, but that CythonExtensionsOnWindows link specifically recommended against it.
Any other suggestions would be very welcome! In particular, since I clearly have all the versions of VS I could possibly need, is there a way to force Python to recognise them, other than setting environment variables VS100COMNTOOLS or similar?
Interestingly conda does seem to recognise the installed compilers, as a separate pip install attempt that failed with this same error, worked with conda.
As it turns out, Python 3.5 needs Visual Studio 2015. Advice elsewhere on fixing this for other Python versions is outdated.
Get Visual Studio 2015 Community here: https://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs.aspx, this worked for me with no further steps needed.
Many thanks to Ionel, apparently the only place on the web to find this information! http://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/
I already asked this question at apple.stackexchange.com, but I was told it was the wrong place for this question - so I will ask it here, as I was suggested to do.
At my university we got the task to implement a c-program which has a GTK-GUI. The GTK-GUI is already implemented, we just have to implement a algorithm which hands it some data.
I already got gcc/g++ working. But when i try to compile the project the compiler returns the error, that it does not find the gtk:
fatal error: 'gtk/gtk.h' file not found
#include <gtk/gtk.h>
^
So my question is:
How do I install gtk on OSX Mavericks for using it with gcc/g++ compiler?
My setup: MacBook Pro Retina Mid 2012 with OSX Mavericks. Homebrew is installed and working if it could be useful for the installation.
(Of course the Apple Command Line Developer Tools are installed)
I finally solved the Problem. tojanfoe suggested in a comment the link http://www.hardcoded.net/devlogs/20120426 which turned out to not be helpful.
This is how i solved it:
1.a) Installation of GTK+ 2.x:
brew install gtk+
1.b) Installation of GTK+ 3.x:
You can install gtk+ 3.x via home brew too if you need that, but the 2.x version is enough for my purposes. The command would be:
brew install gtk+3
2.)
But after the installation I had the problem, that cairo could not be found. So i solved it this way:
export PKG_CONFIG_PATH=/usr/local/Cellar/cairo/1.12.16/lib/pkgconfig/
3.)
Then the compiler said it could not find the package 'xcb-shm', required by 'cairo'. This can be solved this way:
export PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig
After this command the compiler worked as expected.
You can download precompiled Gtk2 Framework from: http://r.research.att.com
http://r.research.att.com/libs/GTK_2.24.17-X11.pkg,
or
http://r.research.att.com/libs/GTK_2.18.5-X11.pkg
And Gtk3 Framework from: http://www.tarnyko.net/dl/gtk.htm
