Hi @shubhankarsharma00 ,

Let us know what you was trying to do and got this error.

You can go through the README file and contribution section

[shubhankarsharma00]

I wanted to setup daru-view. When I ran bundle install I wasn't able to install rbczmq because of some error and then I tried sudo gem install rbczmq and encountered this error.

[Shekharrajak]

@shubhankarsharma00 , may be some dependencies are not installed for rbczmq. Try sudo apt-get install libtool-bin (or some other dependencies) and then sudo gem install rbczmq. The installation steps may help you as well .

[shubhankarsharma00]

I already installed libtool-bin, autoconf, automake and I can't figure out what dependency I am missing. I even tried to get it from the source installed all the dependencies and then ran rake and it gave me same error.

@shubhankarsharma00 This temporary fix might work for you for now.

CPPFLAGS='-Wno-error=deprecated-declarations' gem install rbczmq -v '1.7.9'

See https://github.com/methodmissing/rbczmq/issues/64

[Shekharrajak]

I have setup the development version in different machines (Mac, Debian) following these steps . I hope you have followed it.

I found a similar problem in other system and solved it using above @lokeshh's https://github.com/SciRuby/daru-view/issues/132#issuecomment-455802845 . Hopefully it will solve your issue as well @shubhankarsharma00
