Ruby socket support

Hello all,

I'm getting this error trying to use use gems

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require': no such file to load -- socket (LoadError)

ruby and ruby gems is built against uclibc . I'm trying to figure out
why ruby is not being built with socket support.

any ideas would be helpful

Thanks

zio

A few years ago, I did some network programming on gumstix (uclibc) with ruby, and they did work well. One thing is to make sure to build socket statically (uncomment the line in ext/Setup before building ruby):

http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/227140
http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb/ruby/ruby-talk/227140?226556-227545

Just uncomment all the extensions you think you'll need.

I had this configure option, too: --disable-ipv6. Not sure if that's still needed.

I also had to hack configure.in a little (maybe it was for cross compiling?). My notes are below, but this was for a very early version of ruby 1.9, so YMMV. With any luck, just the static link change will get it working for you.

# configure.in:
# add these lines after AC_FUNC_GETPGRP, in place of AC_FUNC_SETPGRP:

dnl AC_FUNC_SETPGRP does not work if cross compiling
dnl Instead, assume we will have a prototype for setpgrp if cross compiling.
if test "$cross_compiling" = no; then
   AC_FUNC_SETPGRP
else
   AC_CACHE_CHECK([whether setpgrp takes no argument], ac_cv_func_setpgrp_void,
     [AC_TRY_COMPILE([
#include <unistd.h>
], [
   if (setpgrp(1,1) == -1)
     exit (0);
   else
     exit (1);
], ac_cv_func_setpgrp_void=no, ac_cv_func_setpgrp_void=yes)])
if test $ac_cv_func_setpgrp_void = yes; then
   AC_DEFINE(SETPGRP_VOID, 1)
fi

# after patching:
autoreconf

Oddly enough right now i386. you can find the project here
Google Code Archive - Long-term storage for Google Code Project Hosting. . hopefully I can find some arm hardware
so I can start porting to arm.
