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

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  
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.](http://code.google.com/p/uarch/) . hopefully I can find some arm hardware  
so I can start porting to arm.
