I tried the following from this GitHub Issue:
pip install cython
brew install hdf5
brew install c-blosc
export HDF5_DIR=/usr/local/
export BLOSC_DIR=/usr/local/
pip install tables
But still getting the same error. Not sure if it's due to Homebrew using a different path on M1 Macs?
The issue is that Homebrew puts the files in opt/homebrew/opt/
This fixed it for me:
export HDF5_DIR=/opt/homebrew/opt/hdf5
export BLOSC_DIR=/opt/homebrew/opt/c-blosc
Again in completion to remove confusion. Running the following in terminal on Mac M1 should work.
pip install cython
brew install hdf5
brew install c-blosc
export HDF5_DIR=/opt/homebrew/opt/hdf5
export BLOSC_DIR=/opt/homebrew/opt/c-blosc
pip install tables
A solution from here solved the issue for me:

Scroll down and see "solution" provided by camxus
I tried a lot of things from online forums. But never worked. Installed Xcode to see if it works. But it doesn't.
At first, there was an issue with the C executables at the time of the OpenSSL installation. But later, I found from here, the error occurred because of Anaconda installation. So I uninstalled anaconda and tried to install again.
But now it is throwing a different error.

/usr/local/include/secure/_stdio.h:47:27: note: expanded from macro 'sprintf'
__builtin___sprintf_chk (str, 0, __darwin_obsz(str), __VA_ARGS__)
Basically, this says that there was an error while expanding a macro to some line in file num2int.c. So, where is does that macro come from? The log says that the macro was defined in file /usr/local/include/secure/_stdio.h.
This file correspond to a locally installed package, most probably added through brew (it could also have been installed by some application installed with a package installer, but this appears less probable). I have not found yet to which package that file belongs (don't have it on my computer and havn't found any reference to it on Google), but _stdio.h files are rather exceptionnal, so I believe that it might be related to brew's private GCC. Yet, ruby-build (when executed though rb-env install) prefer to use XCode's clang compiler, which might not support some syntax extension supported by brew's GCC.
In short, you end up loading in Apple's clang some local include file that use some syntax thaat is not compatible with that compiler.
What to do now?
You must determine if the /usr/local/include/secure/ directory is actually useful. Maybe, this is related to a program that you no longer use… I can't tell you exactly what to do about this, but here are some ideas:
Check if either secure or secure/_stdio.h is a symlink (i.e.: ls -l /usr/local/include/secure/). If they have been installed by brew, they should point to somewhere under ../Cellar/<package-name>. If there are, maybe you could consider uninstalling that package…
Run brew doctor and check for "Unexpected header files".
Ideally, you want to end up deleting that directory… If you are not certain either it is a good idea, then you may consider moving it temporarilly out of the include directory, for example by doing the following:
mkdir /usr/local/include.disabled
mv /usr/local/include/secure /usr/local/include.disabled/secure
# Compile ruby
mv /usr/local/include.disabled/secure /usr/local/include/secure
rm -rf /usr/local/include.disabled
If none of this works, please post the output of the following commands to a pastebin:
which clang
brew doctor
brew ls
ls -la /usr/local/include
How to move all OSX SDK include files out of local/include
I think the following command should be enough to move all include files pointing to the OSX SDK out of the /usr/local/include directory (my uncertainty here is related to either sub-directories were themselves symlinked, or if it is the content of these subdirectories that is symlinke… I assumed the first, and this oneliner script will miss directories if they are of the second type).
mkdir -p /usr/local/include.disabled/
find /usr/local/include/ -depth 1 -lname '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/*' -exec mv '{}' /usr/local/include.disabled/ ';'
Run these commands, then execute ls -la /usr/local/include again… There should be much less content in it. Do you still have a secure directory there?
And most importanly, can you now get through your original build?
I was facing a similar issue and can recommend the approach below that's related to binutils needing to be uninstalled first. What worked for me:
brew uninstall binutils
# Uninstalling /usr/local/Cellar/binutils/2.33.1... (134 files, 167.6MB)
rbenv install 2.6.5 && rbenv local 2.6.5 ;

# Installing ruby-2.6.5...
# ruby-build: using readline from homebrew
# Installed ruby-2.6.5 to /Users/auser/.rbenv/versions/2.6.5
Prior to this the I was also getting a number of varying messages in ruby-build.log - with the last being:
# ld: symbol(s) not found for architecture x86_64
A number of other steps that I took as part of my homebrew stepup (prior to uninstall) included:
brew install perl ruby rbenv
# // UPDATE PATHs with suggestions made by brew during install
which awk perl
# /usr/local/bin/awk
# /usr/local/bin/perl
# ^^^ IN SHORT ALL PATHs should be with /usr/local/opt OR /usr/local/bin
You can re-install binutils again after as needed and remember to repeat the uninstallation with any future rbenv install version(s) that you're likely to re-execute (note to self).
PS - tested on macOS Catalina 10.15.3 (19D76) successfully installing both 2.4.0 & 2.6.5
Can you try to run these commands:
brew unlink gawk
brew reinstall awk
awk
before running rbenv install 2.4.0
I'm cross-compiling the Dart runtime using the instruction here.
I've installed all the dependencies as specified. I've also cloned the git repository with the necessary tool chain.
I'm running the runtime compilation with this command:

BUILD FAILED
Am I missing any dependency or package?
I hit the same problem. On my ubuntu 14.04 system /usr/include/asm didn't exist. It was called asm-generic instead. I sym-linked it and the build was able to continue.
cd /usr/include
sudo ln -s asm-generic/ asm
The build was able to continue after that.
This is probably because you're trying to build an application without some of the include paths correctly set, for example using a 32-bit gcc on a 64-bit platform.
To resolve:
sudo apt-get install gcc-multilib
I'm not sure why this happens, but sometimes /usr/include/asm gets deleted. My teammates who looked at their Ubuntu x86-64 workstations found that the asm symlink was:
0 lrwxrwxrwx 1 root root 20 May 22 2013 /usr/include/asm -> x86_64-linux-gnu/asm
And the command to recreate it is:
$ cd /usr/include
$ sudo ln -s x86_64-linux-gnu/asm asm
The files in /usr/include/asm-generic are sometimes, but not always, equivalent to the files in the x86-64 specific directory; so it's difficult to recommend symlinking it as a workaround.
I want to install gitlab, which don't recommend to use any ruby version manager.
But

I also ran into this issue trying to install ruby-2.0.0-p247 with rbenv. Save some time by using this patch.
You can run it like this:
curl -fsSL https://gist.github.com/ference/d3d4cbbe18309a91ad9b/raw/267ea89fa145c536967831e1af4dea030297b53e/ruby-2.0.0-p247.patch | rbenv install --patch 2.0.0-p247
This is my solution on Ubuntu 14.04 Server edition.
I need to install underline
sudo apt-get install libreadline6 libreadline6-dev
Then, the problem was fixed.
Found a solution from https://github.com/sstephenson/ruby-build/issues/690. What actually missing is libffi-dev. I tried on Ubuntu 12.04 and it is successful.
sudo apt-get install libffi-dev
I'm trying real hard to install vowpal wobbit and it fails when i run the make file, throwing:
cd library; make; cd ..
g++ -g -o ezexample temp2.cc -L ../vowpalwabbit -l vw -l allreduce -l boost_program_options -l z -l pthread
ld: library not found for -lboost_program_options collect2: ld returned 1 exit status make[1]: *** [ezexample] Error 1'
I then added the links to the boost library here by specifying -L/usr/local/lib
Now I get the following error:
g++ -g -o ezexample temp2.cc -L/usr/local/lib ../vowpalwabbit -l vw -l allreduce -l boost_program_options -l z -l pthread
ld: library not found for -lvw
collect2: ld returned 1 exit status
make: *** [ezexample] Error 1
I happened to get everything working on OS X 10.7 as follows:
Make sure you have a working Boost installation. As indicated on the Getting started page, usually we only need header files, but some Boost libraries must be built separately, including the program_options library which is used to process options from command line or config file. Go into your boost folder, and then at your shell prompt:
$ ./bootstrap.sh
$ ./bjam
This will compile and build everything. You should now have a bin.v2/ directory in your boost directory, with all built libraries for your system (static and threaded libs).
$ ls bin.v2/libs/
date_time iostreams python serialization test
filesystem math random signals thread
graph program_options regex system wave
More importantly, extra Boost libraries are made available in the stage/lib/ directory. For me, these are Mach-O 64-bit dynamically linked shared library x86_64.
The include path should be your_install_dir/boost_x_xx_x, where boost_x_xx_x is the basename of your working Boost. (I personally have boost_1_46_1 in /usr/local/share/ and I symlinked it to /usr/local/share/boost to avoid having to remember version number.) The library path (for linking) should read your_install_dir/boost_x_xx_x/stage/lib. However, it might be best to symlink or copy (which is what I did) everything in usual place, i.e. /usr/local/include/boost for header files, and /usr/local/lib for libraries.
Edit the Makefile from the vowpal_wabbit directory, and change the include/library paths to reflect your current installation. The Makefile should look like this (first 12 lines):
COMPILER = g++
UNAME := $(shell uname)
ifeq ($(UNAME), FreeBSD)
LIBS = -l boost_program_options -l pthread -l z -l compat
BOOST_INCLUDE = /usr/local/include
BOOST_LIBRARY = /usr/local/lib
else
LIBS = -l boost_program_options -l pthread -l z
BOOST_INCLUDE = /usr/local/share/boost # change path to reflect yours
BOOST_LIBRARY = /usr/local/share/boost/stage/lib # idem
endif
Then, you are ready to compile vowpal_wabbit (make clean in case you already compiled it):
$ make
$ ./vw --version
6.1
$ make test
You can also install vowpal wabbit on OS X using brew:
brew install vowpal-wabbit
Or you can just install boost, and then install vw from the github repo.
brew install boost
For installation on CentOS 7 (6.5 perl version is too old for latest vw source code), I've found the instructions at http://wkoplitz.blogspot.be/2012/12/vowpal-wabbit-on-centos.html to work fine:
yum install zlib-devel boost-devel
yum groupinstall "Development Tools"
git clone git://github.com/JohnLangford/vowpal_wabbit.git
cd vowpal_wabbit
./autogen.sh
make
make test
Good news:
As of the latest release VowpalWabbit version 9.1.0, vw no longer relies on Boost program_options
From the release highlights:
Removal of Boost Program Options dependency
For a long time we have depended on Boost Program Options
for command line options parsing. In this release, we have > replaced this dependency with our own implementation of
command line parsing. Apart from one place where we depend > on Boost Math in standalone mode, this means that VW core
and the command line tool are free of Boost dependencies
hopefully making the code a bit easier to build and package.
