libdl not found on HPUX for OpenSSL 32bit build

Question

When tring to build openssl-1.0.2r

I am receiving this error : Can't find library: "dl"

/opt/XPADE/v3/usr/ccs/lbin/ld32: Can't find library: "dl"

The problem is I cannot find libdl on machine for 32 bit. It looks it is only available for 64 bit

$ ls /usr/lib/pa20_32 | grep dl
libdlv_vxfs.1
libdlv_vxfs.sl
$
$ ls /usr/lib/pa20_64 | grep dl
dld.sl
libdl.1
libdl.sl
libdld.1
libdld.sl
libdlv_vxfs.1
libdlv_vxfs.sl

Does anyone knows something about this issue ?

The PA32 (pa20_32) version is called libdld.sl (libdld.2), a copy should have been shipped under /usr/lib (perhaps also /usr/ccs/pa/usr/lib). You could either make a symbolic link named "libdl.sl" in the appropriate directory or change your makefile to use "-ldld" instead of "-ldl".

This is what we use at work to build OpenSSL 1.0.2 on HP-UX PARISC v11.23 with the HP ANSI (aCC) compiler:

CC="cc -Dinline=" $CONFIGURE no-shared hpux-parisc1_1-cc +DA2.0 +DS2.0
# Fix up HP-UX 11i v2 doesn't have the ALT XOPEN library implementation.
for i in `find . -name '*akefile'`
do
  sed 's/-D_HPUX_ALT_XOPEN_SOCKET_API//' $i > $i.new
  mv $i.new $i
done
make clean all

Builds cleanly. On 11.31 you may not need the sed command.
