extremely hard to install rubygems on hpux

? ??

4/7/2009 1:16:00 PM

hi, all.

after installing ruby 1.8.7.p72 successfully, I tried to install
rubygems.1.3.1.

It seems to be normally installed.

but, when I execute it, the errors is generated.

#> gem update
/usr/local/lib/ruby/site_ruby/1.8/ia64-hpux11.31/zlib.so: dlsym:
Unknown symbol Init_zlib - /usr/local/lib/ruby/site_ruby/1.8/ia64-
hpux11.31/zlib.so (LoadError)

actually, this is not a error log what I first met.

first error log is "no load error - zlib".

to resolve this problem, I trace the zlib location ruby wants. the one
of them is "/usr/local/lib/ruby/site_ruby/1.8/ia64-hpux11.31" here.

I make a symbolic link by using /usr/local/lib/libz.so.1.2.3 under
site_ruby/1.8/ia.......

wow. I am still in problems.

this time ruby cannot find "zlib.rb". I am not sure this is main
reason gem is failed. but it could be a reason.

the procedure to execute gem binary is extremely hard. :-<

this is mkkf.log in ruby1.8.7p72/ext/zlib.

-------------------------------------

have_library: checking for deflateReset() in -lz... =20
-------------------- yes

"gcc -o conftest -I../.. -I../../. -I../.././ext/zlib -=20

/* end */

--------------------

checked program was:

1: #include <zlib.h>
/* end */

--------------------


hmn, could be this a kind of clue ?

This won't work as /usr/local/lib/libz.so is not a ruby extension. =20
The ruby zlib extensions loads this file.

These are both ok (in the first instance, deflateReset is probably a =20
macro).

Did you get a zlib.so built? In your ruby checkout:

$ find .ext -name "*zlib*"

If you didn't include your entire mkmf.log

? ??

thanks Eric.

you gave me a fantastic bullet to solve problems.

There is also zlib library in .ext/ia64-hpux11.31.

I copied it in to /usr/local/lib/ruby/site_ruby/1.8/ia64-hpux11.31/.

then I got beautiful gem's results. :)

However, I don't understand why this zlib library didn't be copied =20
with the other libraries.
