Subject: [ruby-core:67005] [ruby-trunk - Bug #10625] configure --with or --without-jemalloc fails

Issue #10625 has been updated by Nobuyoshi Nakada.


This is consist of 2 issues.

* `with_jemalloc` is set to `yes` even if `--without-jemalloc` is given.
* MacPorts jemalloc's `install_name` has the base name only, so its runtime library needs to be located in a system standard library path, or one of `DYLD_LIBRARY_PATH`.

Bug #10625: configure --with or --without-jemalloc fails
https://bugs.ruby-lang.org/issues/10625#change-50533

* Author: Sakuro OZAWA
* Status: Open
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* Category: build
* Target version: 
* ruby -v: trunk@96fc310
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
I have installed jemalloc(version 3.6.0) from MacPorts on OSX Yosemite and tried building ruby trunk@96fc310.

The result were

```
$ ../configure --srcdir=.. --with-opt-dir=/opt/local --with-jemalloc
:
checking size of long long... configure: error: in `/Users/sakuro/Projects/github.com/sakuro/ruby/build-with-jemalloc':
configure: error: cannot compute sizeof (long long)
```
fails.

```
$ ../configure --srcdir=.. --with-opt-dir=/opt/local --without-jemalloc
:
checking size of long long... configure: error: in `/Users/sakuro/Projects/github.com/sakuro/ruby/build-without-jemalloc':
configure: error: cannot compute sizeof (long long)
```
fails.

```
$ ../configure --srcdir=.. --with-opt-dir=/opt/local
:
config.status: creating GNUmakefile
config.status: creating Makefile
config.status: creating ruby-2.2.pc
```
succeeds.

The header of jemalloc resides as /opt/local/include/jemalloc/jemalloc.h and seems correctly recognized by the script.

```
checking for malloc_conf in -ljemalloc... yes
checking jemalloc/jemalloc.h usability... yes
checking jemalloc/jemalloc.h presence... yes
checking for jemalloc/jemalloc.h... yes
```
