Install problem with Cygwin on Win7

[Robert Martin]

I'm trying to install rails on cygwin and am running into problems when the install tries to install nokogiri.

There are a few messages like this before it exits:

nokogiri.c: In function `Init_nokogiri':
nokogiri.c:100:3: error: stray `\' in program
   rb_const_set(mNokogiri, rb_intern("NOKOGIRI_LIBXML2_PATH"), NOKOGIRI_STR_NEW2
(NOKOGIRI_LIBXML2_PATH));

And this looks like it's related to the CPPFLAGS variable

For some reason the -DNOKOGIRI* environment vars look wrong and I can't figure out how to fix/prevent this.

Has anyone come across this before and happen to know how to fix it?

Thanks

We don't currently support native building of Nokogiri. Ongoing discussion here: https://github.com/sparklemotion/nokogiri/issues/1190

Instead, please prefer one of the windows-platform gems that contain pre-built DLLs.

That said, I have no idea whether our Windows gems work for Cygwin; we've only tested against the Ruby one-click installer. Would love to hear how you get on.

Same issue on 1.6.6.2, But 1.5.0 is fine.

Not sure where my reply from yesterday went. Basically I also cannot install Nokogiri on Cygwin since version 1.6.6.2. It worked OK with 1.6.6.1. I can provide more details but would not want to duplicate what I wrote yesterday in case the message surfaces.

Should I rather open a bug for that or do we discuss this here?

Kind regards

Do you mean you do not support building Nokogiri on Windows? Or do you mean you do not support building on Cygwin? The latter would be odd because up until 1.6.6.1 I could install and build Nokogiri on Cygwin with gcc without issues.

I also believe a Cygwin build is more similar to a Linux build than a native Windows build. configure works there and paths and process handling are more like on Linux.

Most likely it will not be compatible. On cygwin shared libs are .so and I am not sure how Windows DLLs would be loaded. Maybe there is a way but I'd rather not go down that route.

I am having the same issue here. My details:

I can provide my last successful gem_make.out and the one for 1.6.6.2 if that helps. Should we open a bug?

Kind regards

Robert,

Thanks for asking this question.

Please send all your logs so we can see what's going on that's causing the failure.

As I said, we don't officially support cygwin, so this is not a bug; but I'm happy to help you out if it's easy to fix in your case.

OK.  I have attached gem_make.out from the 1.6.6.1 and 1.6.6.2 builds. As the original message (below) indicates this seems to be some issue with CPP macros. Versions of Cygwin and compiler can be found at the bottom of my last email (see below).

Could you make any use of the logs I provided? Do you need more information?

Hi,

The error in the log, as you presumably have seen is:

```

nokogiri.c: In function 'Init_nokogiri':

nokogiri.c:100:3: error: stray '\' in program

   rb_const_set(mNokogiri, rb_intern("NOKOGIRI_LIBXML2_PATH"), NOKOGIRI_STR_NEW2(NOKOGIRI_LIBXML2_PATH));

   ^

```

This string comes from the mini_portile recipe and is passed in via a compiler command-line option (see https://github.com/sparklemotion/nokogiri/blob/master/ext/nokogiri/extconf.rb#L529).

Are you using two different gemsets for your 1.6.6.1 and your 1.6.6.2 installations? If so, can you tell me what versions of mini_portile you're using in each?

Right.

I tested again today and got an error I did not notice before:

<command-line>:0:22: warning: missing whitespace after the macro name

I have attached /usr/lib/gems/ruby/2.0.0/nokogiri-1.6.6.2/gem_make.out (compressed).

Do you have any insights yet?

Kind regards

[Rubens Farias]

I was wondering, did anyone have any progress on this?

I stumbled on the same problem... :'(

[Mike Dalessio]

Hi,

The 1.6.7 release candidate supports native builds on Windows, but I have no idea whether Cygwin will work.

Try it and let us know?

[Rubens Farias]

Installing 1.6.7 works fine! Thanks!

How did you install 1.6.7, compiling with DevKit?

[Mike Dalessio]

Yes, we build and test against the Ruby one-click installer devkit.

1.6.7 final should be cut in the next few days.

[Rubens Farias]

I downloaded the gem and installed it with gem install from cygwin.

Nice! Looking forward to the final 1.6.7.
