the three command i entered are
cd /usr/bin
mv perl perl-backup
ln -s /usr/bin/perl /usr/local/bin/perl
this is causing me error bad interpreter: too many levels of symbolic links
Please tell me how to undo this command
Since you only had problems with creating a symlink at the end, you should only need to undo your move, with:
mv perl-backup perl
You should look at the output of:
ls -l /usr/bin/perl /usr/local/bin/perl
to see if either of them are symlinks already.

When trying to run a Makefile from J.DepP, I keep getting /bin/bash: no: command not found. Does anyone know how to fix this? Is there a no program to install?
// Command that fails (split into 2 lines for readability)

That is the error I'm getting, where it's trying to run the no command. When I type no in terminal, it doesn't exist. Line 948 of the Makefile is just the command above.
Has anyone successfully installed J.DepP and fixed this error?
This was actually an issue because python wasn't installed and J.DepP's makefile didn't return a fail for a critical dependency.
Install python, run make clean && ./configure and the issue with disappear.
I'm trying to make install ocaml-wasm 1.
Unfortunately the build is failing with the error-message:
Error: /usr/lib/ocaml/bigarray.cma is not a bytecode object file
Here's a Dockerfile so you may reproduce the error:
FROM base/archlinux
RUN pacman -Sy --noconfirm ocaml ocamlbuild wget unzip make
RUN wget https://github.com/WebAssembly/spec/archive/v1.0.zip
RUN unzip v1.0.zip
CMD cd spec-1.0; make -C interpreter install; bash
You may run it:
docker build -t ocaml-wasm . && docker run --rm -it ocaml-wasm
It should find it to produce the same error as above.
Here's the entire output of the make command:

How do I get ocaml-wasm to compile?
I've seen 2, but the answer doesn't help me. I've not installed any non-standard binaries. Could the ocaml distribution on arch linux be broken?
I suspect that your ocamlbuild version is 0.13 (see ocamlbuild --version), which is known to have this issue. You should use 0.12 to avoid the problem.
ocamlbuild 0.13 is not package on opam because of this problem (so it's not visible to most users), but I hadn't considered that distribution packagers may decide to package it nonetheless.
I've searched around for the problem I encounter when I try to compile libpng, but I can't find a solution.
When I run:
C:\Users\Alex\Desktop\libpng-1.6.21\scripts>make makefile.gcc libpng.a
I receive the following messages:
make: Nothing to be done for `makefile.gcc'.
make: *** No rule to make target `libpng.a'. Stop.
I haven't modified the original makefile.gcc.
I think it's because you didn't call ./configure script.
Accoording to this wiki you need to run in msys shell:
wget http://sourceforge.net/projects/libpng/files/libpng15/older-releases/1.5.16/libpng-1.5.16.tar.xz/download
tar xvfJ libpng-1.5.16.tar.xz
cd libpng-1.5.16
mv INSTALL INSTALL.txt

I'm using fpm to create a deb package, but when I install that deb package, it is installed into the wrong location, my fpm command is:
fpm -f -s "dir" -t "deb" -a "all" -n "my_project" -v 1 -C "/tmp/tmpjWTuVp" /tmp/tmpjWTuVp/my_project
The folder i want to package up exists at /tmp/tmpjWTuVp/my_project, but every time i install it with:
dpkg -i my_package.deb
it installs it into /tmp/tmpjWTuVp/my_project, ideally i'd like it to install into /var/lib/my_project. I have tried --installdir and --root with my dpkg command, but it complains with cannot access archive: No such file or directory
Other information:
I'm installing onto an ubuntu box
I'm very new to deb packaging, so may have missed something obvious
I'm not bound to fpm and happy to hear other viable suggestions
inside my_project is a python virtualenv and my django project
I have randomly found the answer to this immediately after writing this question...
basically the last, unnamed argument within the fpm command can contain an equals separator which defines the directory to come from, and to install to, so the command I ended up using was:
fpm -f -s "dir" -t "deb" -a "all" -n "my_project" -v 1 -C "/tmp/tmpjWTuVp" my_project=/var/lib/my_project
Notice the my_project=/var/lib/my_project, the left side is the directory name of my project (relative, because I used -C to change directory to /tmp/tmpjWTuVp before looking for packages) and on the right side is where I want to install to on the remote machine...
I'm trying to get openmp to run in my program on Mavericks, however when I try to compile using the flag -fopenmp I get the following error:
ld: library not found for -lgomp
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The command I am running is:
gcc myProgram.cpp -fopenmp -o myProgram
Also, when I run gcc I get Clang warnings which I find to be very strange. And looking into /usr/bin/gcc it does not appear to link to Clang.
Any suggestions on how to fix my Clang errors and get openmp to compile?
The gcc command in the latest Xcode suite is no longer the GCC frontend to LLVM (based on the very old GCC 4.2.1) but rather a symlink to clang. Clang does not (yet) support OpenMP. You have to install separately another version of GCC, e.g. by following this tutorial or by using any of the available software package management systems like MacPorts and Homebrew.
I just recently attacked this problem and have scripted the process of getting everything working based on the official instructions.
The script will download everything into ~/code for easy maintenance and will append the correct environment variables to your ~/.profile file. For advanced users, pick a nice location you want the lib, bin and include installed and move them manually. The script depends on knowing the latest OpenMP runtime from Intel, which can be altered at the top of the script.
The script should work out of the box with vanilla Mavericks, except for one small problem. In the OpenML runtime make script, it does not reliably accept clang when specified and continues with the default GCC. As such, if you don't have GCC installed (which is not normal on out of the box Mavericks), it will fail to build. To fix this, you must comment out two lines (as noted in the script) based on the libomp_20131209_oss.tgz build of OpenMP. Newer builds of OpenML might break this script, so use at your own peril on newer versions.
Simply save this script into a file, run 'chmod +x filename.sh', and run './filename.sh' from terminal. It will take a while to build LLVM and Clang, so be patient.
EDIT: This script will most likely fail on Yosemite and I am having issues using the built clang2 after the update to the dev builds of OSX 10.10.

If you are running homebrew you can fix this problem by calling:
brew install clang-omp
The compiler will be available under clang-omp++ name
Just worked through this problem. Here's the answer plus how to get it worked with Xcode.
Grab the latest version of openMP runtime library from
https://www.openmprtl.org/download
unzip and compile it by
mkdir build && cd build && cmake .. && make && sudo make install
install it by
sudo cp ./libiomp5.dylib /usr/lib/
sudo cp ./omp.h /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/
Grab openmp/clang from Git following the instructions on http://clang-omp.github.io/
compile openmp/clang
cd llvm && mkdir build && cd build && ../configure --enable-optimized && make -j
sudo make install
normally it would install clang/clang++ into /usr/local/bin, we need replace the Apple clang with our version
cd /usr/bin
sudo mv clang clang-apple
sudo mv clang++ clang++-apple
sudo ln -s /usr/local/bin/clang ./clang
sudo ln -s /usr/local/bin/clang++ ./clang++
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
sudo mv clang clang-apple
sudo mv clang++ clang++-apple
sudo ln -s /usr/local/bin/clang ./clang
sudo ln -s /usr/local/bin/clang++ ./clang++
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1
sudo mv -f * ../../
Create a project in Xcode, using the Hello World code on clang-openmp website for test. After created, add "-fopenmp" to Custom Compiler Flags -> Other C Flags in project settings; add /usr/lib/libiomp5.dylib to the build phases of project (project settings -> Build Phases -> Drag /usr/lib/libiomp5.dylib into Link Binary with Libraries)
It should work. Yosemite + Xcode 6 is tested.
Note: the custom clang is NOT as stable as Apple's. Switch back if you meet strange instruction error after compiled.
