Ruby

I found a workaround.

There is some documentation of HP-UX PA-RISC compiler here
http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801?ciid=4727276391695110VgnVCM100000275d6e10RCRD

(There's probably a better one somewhere but that's the one I used.)

The +b option is used by the linker to embed a library path list in the executable for use at run time. However, if passing these options via CC or GCC then the option should be -Wl,+b. The mkmf.log file shows, however, that an unknown option +b is being passed directly to gcc.

After running configure I made the following change in config.status -

mv config.status config.status.orig sed -e 's/^.*RPATHFLAG.*$/S["RPATHFLAG"]=" -Wl,+b%1$-s"/' config.status.orig >config.status chmod +x config.status ./config.status 

This results in /usr/local/lib/ruby/1.8/hppa2.0w-hpux11.11/rbconfig.rb having

# grep RPATHFLAG /usr/local/lib/ruby/1.8/hppa2.0w-hpux11.11/rbconfig.rb CONFIG["RPATHFLAG"] = " -Wl,+b%1$-s" 

However, the make step still doesn't run properly because now -Wl,+b gets passed to ld, which is also wrong.

Thus after the make step has finished I made another change -

cd ext/zlib mv Makefile Makefile.orig sed -e 's#^LIBPATH.*$#LIBPATH = -L. -L$(topdir) -L/usr/local/lib +b/usr/local/lib#' Makefile.orig >Makefile make cd ../.. 

That works fine. Then cd ../.. and make install and the zlib extension is installed.

Someone who understands how all this stuff works better than I do can hopefully turn this into an actual patch.

Hi Nobuyoshi,

Yes the patch works.

For people viewing this in the archives, it's worth knowing that patch and diff are different on HP-UX. To apply this patch -

cp -p lib/mkmf.rb lib/mkmf.rb.orig cat <<'EOF' >mkmf.hpux.patch
