Subject: [ruby-core:62691] [ruby-trunk - Bug #9840] [Third Party's Issue] [darwin] configure script fails if an empty file named `Info.plist` exists in the user's home directory

Issue #9840 has been updated by Nobuyoshi Nakada.

Status changed from Open to Third Party's Issue

Why not remove the invalid file?

Bug #9840: [darwin] configure script fails if an empty file named `Info.plist` exists in the user's home directory
https://bugs.ruby-lang.org/issues/9840#change-46817

* Author: patrick ellis
* Status: Third Party's Issue
* Priority: Normal
* Assignee: cruby-mac
* Category: platform/darwin
* Target version: 
* ruby -v: ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
On OS X 10.9.2, the ruby-2.1.2 configure script fails if an empty file named `Info.plist` exists in the user's home directory.

**Steps to reproduce:**

~~~
#!/usr/bin/env bash

touch ~/Info.plist

[[ -f ruby-2.1.2.tar.gz ]] || curl --fail -o ruby-2.1.2.tar.gz -L http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.gz
[[ -d ruby-2.1.2 ]]        || tar xfz ruby-2.1.2.tar.gz

cd ruby-2.1.2

./configure
~~~

The last lines it prints before failing are:

~~~
checking whether LDFLAGS is valid... no
configure: error: something wrong with LDFLAGS=""
~~~

The generated config.log has an error message from `dsymutil` when validating LDFLAGS:

~~~

configure:7120: error: something wrong with LDFLAGS=""

It looks like `dsymutil` is trying to read this empty plist file and fails multiple times during the configure step. It prints an error message multiple times, but only causes `configure` to fail during the LDFLAGS step, making it hard to debug.

Attached is `config.log`, which was generated from running the above code on my system.

I was able to reproduce this bug for all major ruby versions > 2.0.0.

Just for completeness's sake, here is the output of `brew config` from the my system:
