Can't install/compile Eventmachine under Ruby 2.0.0-p0

[Steffen Roller]

Was somebody able to install Thin/Eventmachine using 64-bit versions of DEVKIT and Ruby?

I got the following error message(s):

make

generating rubyeventmachine-x64-mingw32.def

compiling binder.cpp

x86_64-w64-mingw32-g++.exe: error: unrecognized command line option '-EHs'

x86_64-w64-mingw32-g++.exe: error: unrecognized command line option '-GR'

make: *** [binder.o] Error 1

Gem files will remain installed in C:/ruby/lib/ruby/gems/2.0.0/gems/eventmachine-1.0.0 for inspection.

Results logged to C:/ruby/lib/ruby/gems/2.0.0/gems/eventmachine-1.0.0/ext/gem_make.out

under the 32-bit version the error is slightly different:

C:\temp>gem install eventmachine --platform=ruby

Temporarily enhancing PATH to include DevKit...

Building native extensions.  This could take a while...

ERROR:  Error installing eventmachine:

        ERROR: Failed to build gem native extension.

    C:/ruby/bin/ruby.exe extconf.rb

checking for main() in -lssl... *** extconf.rb failed ***

any ideas?

Looks to me eventmachine is not detecting properly the platform or
Ruby and it thinks is Visual C.

The second error is because eventmachine requires OpenSSL.

Search the group to find knapsack packages to download and use as
headers/libs for compilation.

I'm not sure if eventmachine compiles cleanly on Windows "natively",
it used to require cross-compilation.

I suggest report this issue to Eventmachine developers:

https://github.com/eventmachine/eventmachine/issues

and provide them:

ruby -v
gem -v
gcc --v

ruby -rrbconfig -e "p RbConfig::CONFIG.values_at('host_os', 'target_os')"

Hi Luis,

thanks for the info. I did compile before under 1.9.3, 32 bit.

I just switched back to gcc 4.5.2 and ruby 1.9.3-p374.

I'm going to reach out to the EM guys though.

BTW: It seems the version command is now

gcc -v (just one dash?)

gcc --v returned an error on my installation

I only see this:

https://github.com/eventmachine/eventmachine/blob/master/ext/extconf.rb#L79-L82

And this:

https://github.com/eventmachine/eventmachine/blob/master/ext/extconf.rb#L79-L82

The root of the flags being added:

Sorry, was going to type "--version" and then thought "-v" provided
better output.
