Ruby Forum Ruby > Broken Gems on Windows (still)

(I realized I posted this originally on the Rails mailing list, when it
probably should have been here... oops!)

Hello...

Is there any word on when the eventmachine 0.12.2 and sqlite3-ruby 1.2.4
gems are going to be fixed to work when updating gems on a Windows (xp)
system? Doing a 'gem update' will cause errors for both, which causes
the rest of the updated to installed gems to not be updated. I've been
using a workaround script that skips the errors and continues updating,
but I'd be nice to get updated gems.

(I'm also seeing a strange thing with the webby gem - when doing a 'gem
outdated', I see:

webby (0.9.3 < 0.9.3)

and updating causes the "new" version to be installed, but gem outdated
still gives that message.)


Here are the errors for sqlite3-ruby and eventmachine, for what it's
worth...

eventmachine:

Hi,

Looks like eventmachine is a C extension. You either don't have a
compiler installed, or your shell's environment isn't setup right.
Therefore, it fails.

Or did I miss the point of your question somehow?

Whoops...forgot to mention.. I do have (various version) of Visual 
Studio loaded - VS 6, VS 2003, VS 2005, VS 2008. I've tried with each 
versions of VSVARS32.bat, which sets the env vars for the various 
environments.

This is the error, for eventmachine, after running the VSVARS32.bat:

ERROR:  While executing gem ... (Gem::Installer::ExtensionBuildError)
    ERROR: Failed to build gem native extension.

Hm. I had to make one (seemingly unrelated) tweak to em.cpp to build
eventmachine 0.12.2 with VC++ 8 on Windows XP Pro:

--- em.orig     Wed Oct 22 11:13:48 2008
+++ em.cpp      Wed Oct 22 11:20:48 2008
@@ -31,6 +31,9 @@
 #ifdef OS_WIN32
 unsigned gTickCountTickover;
 unsigned gLastTickCount;
+#ifndef EINTR
+#define EINTR WSAEINTR
+#endif
 #endif

After I made that change it seemed to build fine.

In any case, it's not a gem issue, but an issue with eventmachine. I
noticed they aren't shipping a gem with a pre-built binary with the
latest release, which would definitely be handy for the Windows users.

Dan
