Porting Ruby to an embedded target

Ruby
1

Greetings, Rubyists -

I am in the midst of porting the Ruby interpreter to our embedded Intel
CE SoC (as used in GoogleTV and Boxee Box), and I would appreciate some
knowledgeable help.

Here is my configure script, with e-variables:

begin shell script

SDK_ROOT=/opt/DHG/target/sdk-perl/IntelCE-21.1.11174.270772; export
SDK_ROOT

./configure
–prefix=$SDK_ROOT/build_i686/staging_dir
–exec-prefix=$SDK_ROOT/build_i686/staging_dir
–target=i686
–enable-shared
CC=$SDK_ROOT/build_i686/staging_dir/i686-cm-linux/bin/gcc; export CC
CFLAGS="-O2 -Wall"; export CFLAGS
LDFLAGS=$SDK_ROOT/build_i686/i686-linux-elf/lib; export LDFLAGS
CPPFLAGS=""
CXX=$SDK_ROOT/build_i686/staging_dir/i686-cm-linux/bin/g++; export CXX

end shell script

Here’s the end of the output of make:

ld -o .ext/i686-none/enc/encdb.so enc/encdb.o -L. -L. -L. -Wl,-R
-Wl,/opt/DHG/target/sdk-perl/IntelCE-21.1.11174.270772/build_i686/staging_dir/lib
-L/opt/DHG/target/sdk-perl/IntelCE-21.1.11174.270772/build_i686/staging_dir/lib
-lruby -lpthread -lrt -ldl -lcrypt -lm
ld: unrecognized option ‘-Wl, -R’

I know I need to find system headers and add a -I; which ones and what
else is needed?

Thanks in advance!

-Wl is an option on GNU ld: “Pass option as an option to the
linker.”[1] I don’t know if the Intel CE SoC SDK has an equivalent ld
option.

Hmmm… we use GNU tools to compile our SDK. According to that page the call
looks good.

It’s GNU ld, version 2.20.20100303. Is it perhaps the space between the comma
and the -R option? I know GNU is sometimes less than flexible about that. It’s all
from the 4.5.1 gcc package and associated bintools.

Is there a space? It looks like there was no space in the actual
command but only in the error message.
