Asp Forum - 1.8.6 OCI binary extension question

Tim Hunter

1/17/2009 5:00:00 PM

I'm trying to build a new release of RMagick that is compatible with the
Ruby 1.8.6 One-Click Installer. In the past I have used MS Visual Studio
2005 Express Edition.

However, new releases of ImageMagick for Windows are built with Visual
Studio 2008 and when I build RMagick with the 2005 Visual Studio the
resulting library fails, apparently because of some incompatibility. (I
confess I am very inexperienced with Windows development, so I'm not
sure what the incompatibility would be.)

Does anybody know for sure if a binary extension built with Visual
Studio 2008 will work with the current 1.8.6 OCI?

Well, could work, but is doom to failure.

Visual Studio 2008 links to MSVCR80, which is a different CRT than the
one used by OCI (MSVCRT).

Memory allocated by MSVCR80 cannot be freed by other CRT, if happens,
will segfault.

Out of curiosity, what are the chances of getting ImageMagick built
with MinGW? MinGW (GCC) + MSYS (for make and such) links to MSVCRT and
will allow you compile Ruby C Extensions that are compatible.

Shameless plug: you can take a look to rake-compiler[1] for cross-
compilation, so you can generate the extension and the gem from Linux/
OSX.

On a side note and feature request: if you do it, then please make a
static library of ImageMagick, so in that way people can start
installing RMagick gem like a normal gem.

Thanks for your reply, Luis. Actually I was thinking about waiting for
the 1.9.1 and then building a static version, as you suggest. Any timeline?

I've already bookmarked rake-compiler. I'll check it out.

I'm working in getting both 1.8.6 and 1.9.1 build with the same
compiler (MinGW) for One-Click Ruby Installer. It's been hard since
there are several changes from 1.8.x to 1.9.1 that affect the paths
and the recipes for compilation.

I'm targeting end of January to mid-February, soon after 1.9.1 go out.

Luis,

Is there a way to configure rake-compiler to specify a name for the
binary executable that is different from the extension name? The
RMagick binary is RMagick2.so, but rake-compiler assumes it is simply
RMagick. Given the Rakefile:

require 'rake/extensiontask'

Rake::ExtensionTask.new('RMagick')

tim@linux:~/RMagick/projects/RMagick$ rake -T
(in /home/tim/RMagick/projects/RMagick)
rake clean # Remove any temporary products.
rake clobber # Remove any generated file.
rake compile # Compile all the extensions
rake compile:RMagick # Compile RMagick
tim@linux:~/RMagick/projects/RMagick$ rake compile
(in /home/tim/RMagick/projects/RMagick)
cd tmp/i686-linux/RMagick
make: Nothing to be done for `all'.
cd -
cp tmp/i686-linux/RMagick/RMagick.so lib/RMagick.so
rake aborted!
No such file or directory - tmp/i686-linux/RMagick/RMagick.so

Is RMagick2 the name of the extension folder?

rake-compiler is more *convention-over-configuration* while still
letting you do some changes.

http://github.com/luislavena/rake-compiler/t...
(see customization section)

> require 'rake/extensiontask'
>
> Rake::ExtensionTask.new('RMagick')

Just giving that line, rake-compiler is expecting:

ext/RMagick/extconf.rb

Which will generate RMagick.so (or .bundle, depending on the host and
or target).

If it's saying nothing to be done is because it already build the
makefile and it already build? what is the output of "rake clean; rake
compile"

Can you point me to the extconf.rb file of RMagick?

There is room definitely there is room to add more customization, but
I based rake-compiler structure in the PickAxe.

Please let me know if you make progress on this.

Thanks for your prompt reply, Luis. With the exception of the .so
filename I believe rake-compiler is working normally.

The extconf.rb for RMagick is below.

I recognize that rake-compiler wants "convention-over-configuration"
and that this can make it difficult to "import" existing projects,
especially those that don't match the convention. I appreciate your
patience.

Indeed, changing the name of the directory to RMagick2 causes rake-
compiler to know that the name of the .so file is RMagick2.so, at the
cost of changing the name of the directory. The directory structure,
which I based on setup.rb, has been my convention from the beginning
and I prefer not to change it. I believe that it is compatible with
the Pickaxe convention.

RMagick has both a Ruby part and a binary part. The Ruby part is
RMagick.rb and the binary part is RMagick2.so for RMagick 2 and simply
RMagick.so for RMagick 1.

rake-compiler is expecting that the name you supply to it is the
expected name of build so file.

We can bend the convention, so adding this to my todo list:

* Make ext.ext_dir work fully (if it's overwritten do not try to
append another folder)

Adding that, you will have the option to keep the extension name but
with a different directory name.

From my experience I've always keep one extension per folder, and
everything inside ext directory.

But is important keep backward compatibility to some extend.

Just added it:

http://wiki.github.com/luislavena/rake-com...

When do that change, you will be able to:

require 'rake/extensiontask'

Rake::ExtensionTask.new('RMagick2') do |ext|
ext.ext_dir = 'ext/RMagick'
end

Sound good?

I understand.

How you deal with the require in the same folder? you explicitly
require "RMagick.so" ?

Anyway, will work on fix that issue before your next release ;-)

Right now I have a broken Ruby environment, when fixed will patch and
do another rake-compiler release.

Thank you for the feedback Tom (because I know is you) ;-)

Yes, exactly.

Hi Rick,

" & Zip & " was the answer!! I thought I was on the right track but could
not get the " "s and the spaces and the &'s in proper form.

This seems to work for the few zips I have in the drop dkown.

Thanks for the help, always good info here from you guys and gals.

Regrds,
Howard
