I am trying to use torch together with the hdf5 package. I am trying to install it via luarocks install hdf5 but during the build phase I get an error regarding the gcc-plugin header. (gcc relies on clang backend). The complete error message is:
luarocks install --local hdf5

Does anybody has maybe a hint how to fix this issue?
Every help is greatly appreciated!!!
In addition to gcc, you need the headers, which on Linux you can get with sudo apt-get install gcc-4.8-plugin-dev. If you're on a different OS or version of gcc, just substitute the appropriate package manager / gcc version number.
gcc-plugin.h is a part of GCC, so I think you'll really need to install gcc to get that. Clang provides a gcc-compatible front-end script but that merely presents a command-line driver with compatible flags.
You should be able to install GCC using Homebrew: https://apple.stackexchange.com/a/86588
I bet you tried to work on a CS287-16 class :). I have contacted the developer of this library who wasn't that easy to do something to solve the problem. Apparently he has no friends who have a Mac PC... As a workaround I could suggest you to use a Docker container with Linux in it to run Lua scripts. That's what I have ended up with...
Here's the Docker image I was talking about: https://github.com/aoboturov/cs287-16-lua. You could build it yourself and the just run as a Docker container :)

I am running the practice code using the dlib library.
It runs until'cmake', but the above error appears during'make' process. Need to update gcc?
The gcc version is shown below.
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)
How to do it if you need to update the version
I wonder.
The GCC releases page (https://www.gnu.org/software/gcc/releases.html) says that gcc 4.8.5 was released on June 23, 2015.
The GCC developers are really good, but shipping C++17 support two years before C++17 was completed is beyond good.
That compiler may support -std=c++1z for some C++17 features, though.
As others have mentioned your compiler is too old for C++17.
It sounds like you are on either RHEL 7 or CentOS 7. Those OSes support installation of "Developer Toolsets" with newer versions of the compiler and toolchain (in addition to the standard system compiler).
This might be an option for you.
For RHEL 7 see: https://access.redhat.com/documentation/en-us/red_hat_developer_toolset/10/
For CentOS see: https://www.softwarecollections.org/en/scls/rhscl/devtoolset-8/
I am trying to install a c++ compiler on a IBM Power7 with Fedora 26.
In /usr/bin it is installed gcc [(GCC) 7.2.1 20170915 (Red Hat 7.2.1-2)] but it has not the c++ compiler (I tried gcc -lstdc++ but the result is: `
/usr/bin/ld: cannot find -lstdc++
I do not have sudo rights so I have to install everything from source.
I was able to install:
Zlib
Perl
Curl
Git
GNU M4
GMP
MPFR
MPC
EXPAT
APR and APR-UTIL
ISL
but when I try to install locally gcc, after a successfull configure, when I try make I got this error:
configure: error: in `/home/aantonietti/gcc/host-powerpc64-unknown-linux-gnu/gcc':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

I also tried to install clang++ but it needs tons of other dependecies.
Do you have any hint on how to install just the gcc-c++ compiler?
Why don't you run dnf install gcc-c++? It will install the C++ system compiler bring in linking support for libstdc++ as well.
I've just compiled latest reps of LLVM, Clang and libc++. Now however I have no idea how to configure the environment to use them. I've added in $PATH the one to compiled binaries and have set the
$D_LIBRARY_PATH=$(llvm-config --libdir)
but anyway when I test run 'clang' with example file it uses some '/usr/bin/ld' linker which I have no idea what is it (as I've uninstalled 'g++' because thought it was the problem (before 'clang' used some linker from it) and I don't have any other C++ compilers).
So now how do I point out the right 'llvm-ld', libc++ include and library paths? I don't want to pass some complex arguments every-time. Perhaps I should set some environment variables.
I'm also using KDevelop with the same effect.
Don't judge me if this sounds stupid but it's my first time with Linux (have always used Windows before). I'm using latest 'OpenSUSE' dist.

You should be able to run make install with perhaps an optional DESTDIR=/...... so that it doesn't clobber your system files.
Since you're on OpenSUSE, you might as well use your distribution's build services, and install the SVN version of LLVM-Clang from here. You should be able to find libc++ and LLVM itself as well.
Otherwise, make install DESTDIR=/opt/llvm should work, and then you can add /opt/llvm/bin/ to PATH and use libc++ by adding this compile and link option: -stdlib=libc++. You'll need something like /opt/llvm/lib in LD_LIBRARY_PATH as well to find the libc++ so.
This should work pretty much out of the box, but I have only ever used my distribution's packages, not a self-built Clang to do this.
Note that Clang still uses your system linker, ld, and this is fine. Currently, LLVM does not yet provide a fully functional alternative to this program, but they are working on it.
EDIT: It seems you uninstalled too much: Clang also uses the GCC crtbegin and crtend object files. So just install GCC again along with glibc and its dev package.
Has anyone had any luck building gevent 1.0 in Mavericks?
I've tried the following:
pip (as recommended on the gevent package index)
easy_install
compiling from source
I keep getting the same error when building 'gevent.core':

Seems to be a problem with XCode. I made sure I have the XCode (v. 5.0.2) command line tools installed with:
xcode-select --install
But that didn't seem to change anything. Apparently I'm not alone with this problem (a missing /Developer/SDKs/MacOSX10.6.sdk), but I'd like to stick with Enthought's Canopy version of python if I can (and have already spent too much time combing the Apple Developer site to try download MacOSX10.6.sdk directly).
Any suggestions that don't involve starting over with a macport'ed python? Thanks!
IIUC, Apple pulled a fast one on the latest XCode, such that gcc is no longer actually gcc, but is symlinked to clang, which is not compatible with standard Pythons, including Canopy's.
It should work better if you install Xcode 3.2.1 Developer Tools from https://developer.apple.com/downloads/index.action
For me the hint on gevent website helped:
pip install cython git+git://github.com/gevent/gevent.git#egg=gevent
I am having problems with compiling code on my Mac (OS X, 10.6.5).
The code uses f2c.
I don't understand the error, and would really appreciate any help. I wondered if it might be a problem with my compiler, and just in case I reinstalled Xcode, which installs a new g++ compiler. But I still get the same error.
Here's the error:
cc1plus: error: /include: not a directory
cc1plus: error: /lib: not a directory
make: *** [Task1.o] Error 1
Thanks!
This may be an error in the installation of your gcc compiler. It seems it may be looking for includes in /usr/include, but it is missing the first part of the directory. Try executing:
$ gcc -v
to see what directories the gcc you're using has by default. In my case, I see
--prefix=/usr
as one of the options.
