#6 Gem creation fails with ruby 2.3.1

[phipsi]

Hello,

I tried to install FRUIT as described in README but step 4 fails. My environment is:

pc:~$ uname -a
Linux pc 4.8.0-52-generic #55~16.04.1-Ubuntu SMP Fri Apr 28 14:36:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

pc:~/Documents$ ruby --version
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]

pc:~/Documents$ rake --version
rake, version 10.5.0

When running rake install in fruit_processor_gem I get the following message:

pc:~/Documents$ cd fruit/fruit_processor_gem/

Is there a workaround to have it run?

Thanks

Thanks for the detailed report. I installed Ubuntu16 and reproduced the error.
On the error

Gem::InvalidSpecificationException: ["test/for_test_picker/fruit_basket_gen.f90"] are not files

please try replacing a line in fruit_processor_gem/rakefile

   'test/for_test_picker/*.f90',

with

   'test/for_test_picker/*_test.f90',

It has fixed the problem on my Ubuntu16.

Many thanks for the fix. Now it works.
