where to find patches for old machine

[alexklein]

Hi all,

We have an old HPUX PARISC c3700 Workstation and when I'm trying to compile OpenSSL (64-bit) using gcc I have this error:

/usr/ccs/bin/ld: Can't find library for -ldl

When searching on the machine I can't find a file named libdl.so.

$ find / -name libdl.*
/usr/lib/pa20_64/libdl.1
/usr/lib/pa20_64/libdl.sl

When I'm looking at another HPUX, but this one is an Itanium, I can find the file there:

/usr/lib/hpux32/libdl.so
/usr/lib/hpux64/libdl.so

I read somewhere that I should install patches but I don't know where I can download them and how to apply them. I found this website but I'm not sure which file to download:
http://h20565.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=75232&swLangOid=8&swEnvOid=7

Here is more info about our HPUX Parisc:

uname -a
HP-UX hpux B.11.11 U 9000/785 2015318450 unlimited-user license

Thank you for your help.

   I believe that the naming/directory conventions changed between
PA-RISC amd IA64.  So, not amazing,  (These changes also tend to confuse
some open-source software products.)

   Ok.  Also known as "11i v1".  I'd bet that "another HPUX, but this
one is an Itanium" is a different version, which might also matter.

   Which "somewhere"?   What makes you think that any patches will fix
this problem?

> [...] not sure which file to download:

   First, if you're running 11.11, then you'd want patches for 11.11.
Second, HP now provides patches only to people who have a support
contract.  Do you have one?

   Did you look for a pre-built OpenSSL kit for your HP-UX version?  My
Web search for "openssl hp-ux 11.11" found many things, including:

http://hpux.connect.org.uk/hppd/hpux/Development/Libraries/openssl-1.0.2g/

   This may all be interesting, but what's the actual problem which you
are trying to solve?

[Dennis Handly]

As Steven said, you're not going to be able to get patches without a support contract.

>/usr/ccs/bin/ld: Can't find library for -ldl

>When searching on the machine I can't find a file named libdl.so.

You found it, PA-RISC shlibs are named .sl.  /usr/lib/pa20_64/libdl.sl

I'm not sure if there were patches to move this into PA32.  There the lib was -ldld.

Are you sure you are compiling for 64 bit?

>I found this website but I'm not sure which file to download:

Hmm, I'm not sure how HP Inc. thinks it can support PA-RISC workstations, when you need HP-UX Language patches, which comes from HPE.  But it looks like those are links to HPESC.

Thank you Steven and Dennis for your answers.

> Which version of OpenSSL? GCC? How, exactly, are you "trying to compile" it?

• OpenSSL 1.0.2h
• GCC 4.2.3

I'm compiling OpenSSL to use it as a static library for my application:

./Configure hpux64-parisc2-gcc --prefix=/path/somewhere no-shared no-zlib no-zlib-dynamic no-rc5 no-idea no-ec no-ecdh no-ecdsa no-asm no-mdc2 no-bf no-cast no-md2 no-rc4 no-jpake no-gmp
make depend
make

> Ok. Also known as "11i v1". I'd bet that "another HPUX, but this one is an Itanium" is a different version, which might also matter.
True.

• HPUX Itanium 11i v2
• HPUX parisc 11i v1

> Which "somewhere"? What makes you think that any patches will fix this problem?
I was exchanging email with someone, and he said it's always good to apply patches on a system. Which I think it is true.

> Do you have one [support contract]?
Unfotunately no...

> Are you sure you are compiling for 64 bit?
I'm using "hpux64-parisc2-gcc" and in the Configure file of OpenSSL:

"hpux64-parisc2-gcc","gcc:-O3 -DB_ENDIAN -D_REENTRANT::::-ldl:SIXTY_FOUR_BIT_LONG MD2_CHAR RC4_INDEX RC4_CHAR DES_UNROLL DES_RISC1 DES_INT::pa-risc2W.o:::::::::::::::void:dlfcn:hpux-shared:-fpic:-shared:.sl.\$(SHLIB_MAJOR).\$(SHLIB_MINOR):::/pa20_64",

But that's a good question because if I add this parameter when building OpenSSL: -L/usr/lib/pa20_64

Then it failed with a different error:

/usr/ccs/bin/ld: /usr/lib/pa20_64/libdl.sl: Mismatched ABI. 64-bit PA shared library found in 32-bit link.

$ file /usr/lib/pa20_64/libdl.1
/usr/lib/pa20_64/libdl.1: ELF-64 shared object file - PA-RISC 2.0 (LP64)

>I'm using "hpux64-parisc2-gcc" and in the Configure file of OpenSSL:

That doesn't seem to do the trick.  You need to compile with -mlp64.

>if I add this parameter when building OpenSSL: -L/usr/lib/pa20_64

>/usr/ccs/bin/ld: /usr/lib/pa20_64/libdl.sl: Mismatched ABI. 64-bit PA shared library found in 32-bit link.

This says you compiled in 32 bit mode.

[alexklein]

Dennis,

I thought about it as well. I tried with -mlp64 but it seems for SPARC it should be -m64 (http://hpux.connect.org.uk/hppd/hpux/Gnu/gcc-4.2.3/)

Anyway, it is the same result using -m64 or -mlp64:

cc1: error: unrecognized command line option "-m64"

Even with a simple helloworld file:

$ gcc -m64 helloworld.c -o helloworld
cc1: error: unrecognized command line option "-m64"

Command file:

$ file /usr/local/bin/gcc
/usr/local/bin/gcc: PA-RISC2.0 shared executable dynamically linked
$ file /usr/local/bin/gmake
/usr/local/bin/gmake: PA-RISC2.0 shared executable dynamically linked
$ gcc --version

That's what it is for Integrity.  You may have to download the sources to figure out what the option is.

I thought that gcc had two different compilers for PA-RISC, 32 or 64 bit:

http://h21007.www2.hpe.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801/?ciid=2a08725cc2f02110725cc2f02110275d6e10RCRD

[alexklein]

I could build OpenSSL without installing any patches with GCC 3.4.5 (for both 32-bit and 64-bit).

At first, I downloaded GCC from http://hpux.connect.org.uk/hppd/hpux/Gnu/gcc-4.2.3/. But there is no 32/64 bit. The Gcc on this Website is good only from HPUX itanium.

On the Website you suggested, I tried with GCC 4.7.1 and 4.1.2 but got the error "ld: Unsatisfied symbol "pthread_mutex_unlock". Probably my ld is too old. But with Gcc 3.4.5 it is OK.

So now I should be ok. Thanks Dennis for your help.

>got the error "ld: Unsatisfied symbol "pthread_mutex_unlock". Probably my ld is too old.

This has nothing to do with ld(1) but either pthread headers or libpthread.
