Cannot compile ruby-oci8 gem about ruby-buildpack

[giner]

As a test I tried to put oracle libs to libs_native and apply the following change to the buildpack and it worked for me:

--- a/bin/compile
+++ b/bin/compile
@@ -6,6 +6,8 @@ $stdout.sync = true
 cache_dir = ARGV[1]
 compile_extensions_dir = File.expand_path(File.join(File.dirname(__FILE__), '..', 'compile-extensions'))

+ENV["LD_LIBRARY_PATH"] = "#{ARGV[0]}/libs_native"
+
 exit(44) unless system("#{compile_extensions_dir}/bin/check_stack_support")

 $:.unshift File.expand_path("../../lib", __FILE__)

Environment variables specified in an application's manifest.yml file are exposed during staging (at least in CF v239, not sure about v230). You may be able to set LD_LIBRARY_PATH there.

@sclevine is this behavior documented somewhere? I checked https://docs.cloudfoundry.org/devguide/deploy-apps/manifest.html#env-block but couldn't find any mention of this...

[giner]

Thank you @sclevine. I can confirm, specifying variable in manifest helps (release v230).
At the same time it seems to be not mentioned anywhere in documentation as @CAFxX already said.

Thanks @CAFxX and @giner for bringing this to our attention. Submitted a PR to the docs to update it with a note about the manifest env vars being in the staging container environment as well: cloudfoundry/docs-dev-guide#137

I have added the LD_LIBRARY_PATH: /home/vcap/app/ld_library_path to manifest file, but still the ruby oci8 gem fails. Please assist me.

@pcsgithubid Did that work for you? I am looking for the same. Please let me know. Thanks.

[n-gottam]

@liuweichu Could you please share what you ended up doing to resolve this?

[pcsgithubid]

@liuweichu Still working on this issue

@pcsgithubid @n-gottam If you could open a new issue and provide a sample app which fails, we can look into this for you

[giner]

@pcsgithubid, the following should work:
LD_LIBRARY_PATH: ld_library_path
or
LD_LIBRARY_PATH: mylib:/tmp/app/mylib
