Failed to install nmatrix on ruby 2.0.0-p247 #505

ruggieroguida · 2016-04-24T23:03:32Z

Using rbenv I have succesfully installed nmatrix on ruby 2.2.0.

However the installation fails on ruby 2.0.0-p247 with with following errors
See here for the log.

std::tuple is a C++11 feature. What compiler are you using? It looks like you need a newer version.

ruggieroguida · 2016-04-25T06:42:44Z

I have installed gcc with brew install gcc. If I run the command again I receive: Warning: gcc-5.3.0 already installed.

From the content of mkmf.log it looks like it is using clang instead.

Sorry, I have edited the comment. I have successfully installed nmatrix on 2.2.0 and not 2.0.0. In both case I am using gem install nmatrix Shouldn't they use the same compiler?

wlevine · 2016-04-25T14:40:06Z

I'm not quite sure why that is happening. For the time being, could you just try editing extconf.rb to force it to use g++? You can comment out this block of code and replace it with:

CONFIG['CXX'] == 'g++'
$CXX_STANDARD = 'c++11'

but make sure you use the correct name for the g++ binary, it may actually be called g++-5.3

If that works, then we can try to find a better solution.

Any progress with this, or can I close it?

ruggieroguida · 2016-05-09T14:44:47Z

No progress unfortunately. You can close it.

Did you attempt @wlevine's suggestion?

ruggieroguida · 2016-05-09T14:55:59Z

I did, but it didn't work.

translunar · 2016-05-12T14:04:14Z

@Rojj How are you installing NMatrix? From git, or from gem?

ruggieroguida · 2016-05-12T14:10:47Z

From the gem

@Rojj Try from git. I think there have been some recent changes that may affect your outcome.

chrhansen · 2016-07-08T08:18:23Z

Hi @MohawkJohn, I just had to install NMatrix for the first time to use it in a Ruby wrapper around Tensorflow https://github.com/chrhansen/ruby-tensorflow/pull/1/files, but gem install nmatrix failed because of the GCC 4.3 requirements. I updated gcc using brew install gcc, but that wasn't picked up on my Mac, gcc --version still uses Apple's preinstalled 4.2.1.

Eventually, I found this issue, installed from git so that I could override extconf.rb like @wlevine suggested above, and after that I can finally do gem 'nmatrix' in my own ruby-tensorflow-gem. However, for future users of ruby-tensorflow this is a bit of a hassle, to say the least. How could this be made simpler and less error prone?

wlevine · 2016-07-08T12:35:38Z

@MohawkJohn, do you think we should default to clang on OS X?

translunar · 2016-07-08T15:28:21Z

Yes, definitely. #525

mrkn · 2016-07-28T03:13:18Z

@Rojj Is your problem fixed by nmatrix-0.2.3 ?

chrhansen · 2016-07-28T17:52:58Z

@mrkn I don't know if I did something wrong or my system is special, but I followed the installation instructions and on OSX El Capitan using this version e3e5d12 I still have rake compile-issues.

In the installation process I get this:

$ bundle install
Fetching gem metadata from https://rubygems.org/
Fetching version metadata from https://rubygems.org/
You have requested:
  json ~> 2.0.1

The bundle currently has json locked at 1.8.3.
Try running `bundle update json`

If you are updating multiple gems in your Gemfile at once,
try passing them all to `bundle update`

Then

$ bundle update json
Fetching gem metadata from https://rubygems.org/
Fetching version metadata from https://rubygems.org/
Resolving dependencies...
Bundler could not find compatible versions for gem "json":
  In Gemfile:
    json (~> 2.0.1)

    rdoc (>= 4.0.1, ~> 4.0) was resolved to 4.2.2, which depends on
      json (~> 1.4)

But bundle update works:

$ bundle update

...
Using nmatrix-lapacke 0.2.4 from source at `.`
Bundle complete! 12 Gemfile dependencies, 21 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

After that I do bundle exec rake compile:

$ bundle exec rake compile

All I needed install Nmatrix 20 days ago was to follow @wlevine's example mentioned above, #505 (comment), but it seems #530 touches a lot of other things. Perhaps I'm missing something, just wanted to show my install-log.

@mrkn not yet.

This is the error I get

@Rojj I think we need to see the compiler output. Can you clone from git and build manually with bundle exec rake compile?

ruggieroguida · 2016-08-14T10:00:29Z

@MohawkJohn I cloned the repository in my home directory. From within the directory I run bundle exec rake compile and I get the following output
