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…
-------------------- yes
“gcc -o conftest -I…/… -I…/…/. -I…/…/./ext/zlib -
D_FILE_OFFSET_BITS=64 -g -O2 conftest.c -L. -L…/… -L. -
lruby-static -lz -lpthread -ldld -ldl -lm -lc”
conftest.c: In function ‘t’:
conftest.c:3: error: ‘deflateReset’ undeclared (first use in this
function)
conftest.c:3: error: (Each undeclared identifier is reported only once
conftest.c:3: error: for each function it appears in.)
checked program was:
/* begin /
1: /top/
2: int main() { return 0; }
3: int t() { void ((volatile p)()); p = (void (()()))deflateReset;
return 0; }
/ end */

checked program was:
/* begin /
1: /top/
2: int main() { return 0; }
3: int t() { deflateReset(); return 0; }
/ end */
have_header: checking for zlib.h… -------------------- yes
“gcc -E -I…/… -I…/…/. -I…/…/./ext/zlib -D_FILE_OFFSET_BITS=64 -
g -O2 conftest.c -o conftest.i”
checked program was:
/* begin /
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.
The ruby zlib extensions loads this file.

These are both ok (in the first instance, deflateReset is probably a
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
with the other libraries.
