Error while installing gems with native extensions inside docker

[Auxilus]

While building #1361 the docker is showing error while installing gems with native extensions, other gems ( that don't need native extensions like mini_portile from the screenshot ) install correctly.

The error says :

Fetching: nokogiri-1.8.0.gem (100%)

ruby.h seem to be at $PREFIX/include/ruby-2.4.0/ruby.h so try symlinking it to the include dir

[Auxilus]

Like ln -s $PREFIX/include/ruby-2.4.0/ruby.h /usr/lib/ruby/include/?

[Auxilus]

Still got the error

Check https://github.com/Auxilus/termux-packages/blob/08bca9c9c3e0615d9175353de57fe57ba5d120b0/packages/metasploit-framework/build.sh#L62

[Auxilus]

Is ruby.h even there at $PREFIX/include/ruby-2.4.0/ruby.h ?

[Grimler91]

If ruby is in termux_pkg_depends, then yeah, otherwise no

[Grimler91]

$PREFIX won't work though since we are in the docker image, use $TERMUX_PREFIX

[Auxilus]

K

[Auxilus]

Yeah doint it atm ty..

[Auxilus]

@Grimler91 still got the error
https://raw.githubusercontent.com/Auxilus/termux-packages/3e8aaa4df5c4f8bf7a3a3cb4663980019c3ed1fe/packages/metasploit-framework/build.sh

[Auxilus]

@Grimler91 it says no such dir called /usr/lib/ruby/include/

[Grimler91]

Yeah, that's a weird path..

ln -s $TERMUX_PREFIX/include/ruby-2.4.0/ruby.h /usr/lib/ruby/include/
should be
ln -s $TERMUX_PREFIX/include/ruby-2.4.0/ruby.h $TERMUX_PREFIX/include/

[Auxilus]

@Grimler91 still not working, can you please take a look?

Execution : https://tmate.io/t/ro-jqGnv00vKRC7WJ8PsbcwAo0um

[Auxilus]

also it says no dir when i do symlink to $TERMUX_PREFIX/lib/ruby/include/ , Do I have to create $TERMUX_PREFIX/lib/ruby/include/ ?

[Droid-MAX]

I also got some errors when I updated the package, and then metasploit could not be used.
