Build error of 5.1.0 due to RString

Build error of 5.1.0 due to RString

[Olivier FAURAX]

Hello,

I'm new to Ruby & Unicorn, and I get a build error trying to compile 
unicorn 5.1.0.

It is about a RString that has not some members, so perhaps an API has 
been modified somewhere.
I tried with unicorn 5.2.0, and I get the same error.

Thanks in advance
Olivier

OK, ruby.h is there, so development headers exist...

These last two lines do not look right.  Can you show us your
mkmf.log file?  The output you originally posted is not enough
as it doesn't show the long compiler options and paths used.

Perhaps a library file is missing for static linking,
since these function checks require.

I'm not familiar with bitnami and how it builds/installs
Ruby, so maybe it's missing libruby*static.a or looking
in the wrong place somehow.

<snip> The failing code should've never been compiled
in the first place and should probably be removed.
However, the rb_hash_clear() detection is still necessary...

Thanks for reporting this.  You might want to loop in somebody
familiar with bitnami to poke around, too.

As I suspected, something is wrong with the install or build
of Ruby itself (not unicorn).

Does Bitnami build your Ruby installation or do you build and
install Ruby in your local environment using Bitnami?

It could be they used a buggy version of binutils
(or you have a buggy version installed locally).

Can you ask the Bitnami folks for help?

Thanks.
