/usr/ccs/bin/ld: Can't find library: "dl" on HP-UX

[Amit Basnak]

Dear friends

We are in the process of creating the new server binary for Systinet Server for C++ . We have compiled the demo folder with the command /opt/systinet/server_cpp65/share/doc/waspc/demos> ./configure CXX=/opt/aCC/bin/aCC LD=/opt/aCC/bin/aCC

and it was successul and I used aCC compiler as the linker instead of system default (/usr/ccs/bin/ld) now doing make Im getting the following error
$ make all
No suffix list.
Making all in basic
No suffix list.
Making all in arrays
cd ../.. && make am--refresh
No suffix list.

/usr/ccs/bin/ld: Can't find library: "dl"
*** Error exit code 1
Stop.
*** Error exit code 1

*** Error exit code 1
Stop.

I do have the said library at: /usr/lib/pa20_64/libdl.1
but adding it to the Make file did not work.
also having specified aCC compiler as linker while running ./configure , the error shows still is uses system default linker /usr/ccs/bin/ld. Im not sure why .

All the 64 bit libraries of HP-UX are under /usr/lib/pa20_64 directory .

Any idea How do I get rid of the error ??

Thanks for your time

Amit

Hi Amit,

you wrote that "dl" library is into /usr/lib/pa20_64/libdl.1. Are you sure that dl library is for 64bit? If it's a 32bit library then you have to put it into /usr/lib:

============
The Default Library Search Path

By default, ld searches for libraries in the directory /usr/lib/hpux32 for 32-bit executables and /usr/lib/hpux64 for 64-bit executables.

(1)
/usr/lib/ (for PA32)
/usr/lib/pa20_64/ (for PA64)
/usr/lib/hpux32/ (for IPF 32-bit)
/usr/lib/hpux64/ (for IPF 64-bit)
============

Check by

file libdl.1

either it's 64bit. If it's a 32bit library try to put "dl" library into /usr/lib and run again make.

HTH.

Best regards,
Fabio

Shalom,

Is the effected library on the SHLIB_PATH ?

Fabio thanks for the reply

I didnt get when you wrote

it's 64bit. If it's a 32bit library try to put "dl" library into /usr/lib and run again make.


You mean to say to copy the respective file to /usr/lib ?

well we are using 64 bit HP-UX system. I reckon its in /usr/lib/pa20_64

Also When I mentioned my linker from /opt/aCC/bin/aCC
why the default linker /ld is used Idont understand

Thanks
Amit

For PA32, you should link with -ldld, not -ldl. For PA64 and IPF there is a libdl.

>the error shows still is uses system default linker /usr/ccs/bin/ld. Im not sure why

Because aCC is a driver, not a linker but eventually invokes ld.

>You mean to say to copy the respective file to /usr/lib?

No! Don't do that.

>well we are using 64 bit HP-UX system.

All this means is that you could create 64 bit applications but you didn't.
So, you should change your makefile to replace -ldl by -ldld.

>Steven: Is the effected library on the SHLIB_PATH?

Since this a linker error, SHLIB_PATH has no affect.

Thanks Denis, Steven and Fabio

I did a grep for ldl and here is what I have
here are the files that contains ldl

So there is no Makefile yet which has ldl in it.
Also the configure file which is used to build Makefile has the following

# if libdl is installed we need to link against it
echo "$as_me:$LINENO: checking for dlopen in -ldl" >&5
echo $ECHO_N "checking for dlopen in -ldl... $ECHO_C" >&6
if test "${ac_cv_lib_dl_dlopen+set}" = set; then
echo $ECHO_N "(cached) $ECHO_C" >&6
else
ac_check_lib_save_LIBS=$LIBS
LIBS="-ldl $LIBS"

if test $ac_cv_lib_dl_dlopen = yes; then
lt_cv_dlopen="dlopen" lt_cv_dlopen_libs="-ldl"
else


lt_cv_dlopen="dyld"
lt_cv_dlopen_libs=
lt_cv_dlopen_self=yes


fi
---------------------------------------------------------------------------­------------------------------------------------


For -ldld


if test $ac_cv_lib_svld_dlopen = yes; then
lt_cv_dlopen="dlopen" lt_cv_dlopen_libs="-lsvld"
else
echo "$as_me:$LINENO: checking for dld_link in -ldld" >&5
echo $ECHO_N "checking for dld_link in -ldld... $ECHO_C" >&6
if test "${ac_cv_lib_dld_dld_link+set}" = set; then
echo $ECHO_N "(cached) $ECHO_C" >&6
else
ac_check_lib_save_LIBS=$LIBS
LIBS="-ldld $LIBS"
-------------------------------------------
Also if I configure al over again like

CXX=/opt/aCC/bin/aCC LD=/opt/aCC/bin/aCC -L /usr/lib/pa20_64 -ldld

the files in my /usr/lib/pa20_64 directory are
libdl.1
libdl.sl
libdld.1
libdld.sl

there is no libdl.a file in pa20_64

Thanks for all your help and time

>Also the configure file which is used to build Makefile has the following

This needs to check for libdld.

>CXX=/opt/aCC/bin/aCC LD=/opt/aCC/bin/aCC -L/usr/lib/pa20_64 -ldld

You should NOT use pa20_64 if you are making a 32 bit application.

>there is no libdl.a file in pa20_64

This libdld and libdl only come in a shared lib form.

Thanks again for your time. I was going through the documentation for the Systinet Server for C++ and realized that Systinet OpenSSL binary is needed as Systinet Server for C++ for HP-UX is compiled against these binaries.

I looked for the OpenSSL binary distribution i.e openssl-0.9.7e for HP-UX but could't find one. On openssl.org thay have source distribuation not the binary distributions and source distribution wont work on systinet Binary distribution .
Any idea where I could find openSSL binary for HP-UX ?

Thanks a lot for the time and your expert comments.

best regards
Amit
