[ruby-core:99486] Core Ruby Build question

[Maurice Smulders <maurice.smulders@genevatech.net>]

Hello,

As cross compiling Ruby Gems other than windows versions has proven to
be impossibly difficult. i resorted to another solution. I installed
the needed files from cbor-ruby into the /ext subtree into the core
ruby source in our buildroot environment. I am mostly successful,
except for one small hiccup.

Ruby version 2.7.1

My source tree looks as follows:

|-- ext
|   |-- cbor
|   |   |-- buffer.c
|   |   |-- buffer.h
|   |   |-- buffer_class.c
|   |   |-- buffer_class.h
|   |   |-- cbor.gemspec
|   |   |-- cbor.h
|   |   |-- compat.h
|   |   |-- core_ext.c
|   |   |-- core_ext.h
|   |   |-- extconf.rb
|   |   |-- lib
|   |   |   |-- cbor
|   |   |   |   `-- version.rb
|   |   |   `-- cbor.rb
|   |   |-- packer.c
|   |   |-- packer.h
|   |   |-- packer_class.c
|   |   |-- packer_class.h
|   |   |-- rbinit.c
|   |   |-- renamer.h
|   |   |-- rmem.c
|   |   |-- rmem.h
|   |   |-- sysdep.h
|   |   |-- sysdep_endian.h
|   |   |-- sysdep_types.h
|   |   |-- unpacker.c
|   |   |-- unpacker.h
|   |   |-- unpacker_class.c
|   |   `-- unpacker_class.h

Target installation is:
./usr/lib/libtinycbor.so
./usr/lib/ruby/2.7.0/cbor
./usr/lib/ruby/2.7.0/cbor/cbor
./usr/lib/ruby/2.7.0/cbor/cbor/version.rb
./usr/lib/ruby/2.7.0/cbor/cbor.rb
./usr/lib/ruby/2.7.0/powerpc-linux-gnuspe/cbor
./usr/lib/ruby/2.7.0/powerpc-linux-gnuspe/cbor/cbor.so
./usr/lib/ruby/gems/2.7.0/specifications/default/cbor-0.5.9.6.gemspec
./usr/lib/ruby/gems/2.7.0/gems/cbor-0.5.9.6
.
It needs to be:
./usr/lib/ruby/2.7.0/cbor/version.rb
./usr/lib/ruby/2.7.0/cbor.rb
./usr/lib/ruby/2.7.0/powerpc-linux-gnuspe/cbor
./usr/lib/ruby/2.7.0/powerpc-linux-gnuspe/cbor/cbor.so
./usr/lib/ruby/gems/2.7.0/specifications/default/cbor-0.5.9.6.gemspec
./usr/lib/ruby/gems/2.7.0/gems/cbor-0.5.9.6

Note the cbor.rb file and version.rb file need to be moved up one directory.
I have made changes to

misc/expand_tabs.rb:  cbor

I also looked at other ext(ensions) like openssl:

From:
./ext/openssl/lib/openssl.rb
./test/rubygems/fake_certlib/openssl.rb

installed:
./ruby/2.7.0/openssl.rb

I am missing something, but don't know what yet...
 What script/file controls the install destination?
