Unable to compile and run SAP/Rfc on solaris: RfcI...

Hi All,

After trying a lot I want to post it here as the last chance.

- I have the unicode version of rfcsdk installed at /usr/sap/rfcsdk

- I downloaded and un-tarred saprfc-0.36. I could create 'saprfc.so' without any error.

- I believe the function call 'RfcInstallUnicodeStructureU' used by saprfc.c is located in a library 'librfcu.a'.

sapscp@moe$ strings librfcu.a | grep RfcInstallUnicodeStructureU

RfcInstallUnicodeStructureU

I am able to create the library saprfc.so without any issue but I see the following error when I try to execute test.rb.

skarumur@reality$ ruby test.rb

dirs: ["./ext/saprfc", "/usr/local/lib/ruby/site_ruby/1.8", "/usr/local/lib/ruby/site_ruby/1.8/sparc-solaris2.8", "/usr/local/lib/ruby/site_ruby", "/usr/local/lib/ruby/1.8", "/usr/local/lib/ruby/1.8/sparc-solaris2.8", "."]

ld.so.1: ruby: fatal: relocation error: file /usr/local/lib/ruby/site_ruby/1.8/sparc-solaris2.8/saprfc.so: symbol RfcInstallUnicodeStructureU: referenced symbol not found

Killed

NOTE: My LD_LIBRARY_PATH has the directory of librfcu.a

Thanks for any help,

Sri

To me, it looks like the compile process has not linked in the library 'librfcu.a'. Can you show me the complete output of the setup.rb/compile process.

Piers,

Thanks for the quick response.

- First I tried

ruby setup.rb config --with-unicode=yes

ruby setup.rb setup

- Then I manually changed the lrfc to lrfcu in the ext/saprfc/Makefile and then ran

make

ruby setup.rb install

right - you don't have the dynamic load library librfcum - you seem to only have a static librfcu.a.

What you will have to do is edit setup.rb and try replacing all occurances of the string "rfcum" with "rfcu", and try again (config, setup, and install).

Cheers.

1. I do have a library librfcum.so. I guess it's not the one.

I changed the rfcum to rfcu in ext/saprfc/extconf.rb and reran clean;config;setup and install. I still have the issue.

2. Not sure if it's related but I see a warning:

ld: warning: file /usr/sap/rfcsdk/lib/librfcu.a(rfcilib.o): wrong ELF class: ELFCLASS64

Was wondering if this is related to 64/32 bit issues. There is no 32 bit unicode version. I tried 32 bit non-unicode version of rfcsdk but it starts pumping hundreds of errors like below during the compile time:

[code]<unknown> 0x40510 /usr/sap/rfcsdk_32_non_unicode/lib/librfc.a(rscpa0lib.o)

<unknown> 0x40520 /usr/sap/rfcsdk_32_non_unicode/lib/librfc.a(rscpa0lib.o)

<unknown> 0x40528 /usr/sap/rfcsdk_32_non_unicode/lib/librfc.a(rscpa0lib.o)

<unknown> 0x40538 /usr/sap/rfcsdk_32_non_unicode/lib/librfc.a(rscpa0lib.o)

<unknown> 0x40540 /usr/sap/rfcsdk_32_non_unicode/lib/librfc.a(rscpa0lib.o)

<unknown> 0x40588 /usr/sap/rfcsdk_32_non_unicode/lib/librfc.a(rscpa0lib.o)

[/code]

3. Probably not related to this issue but I wonder why I see the error about missing libsapu16 though I have libsapu16.so.

checking for main() in -lsapu16... no

DID NOT find libsapu16 - this may cause problems ...

This is odd - I must admit to not knowing much about building software on Solaris.

Have you got the right library version 32bit or 64bit depending on your archtecture (you seem to suggest that you have 32bit?). If you don't get this right then you wont have much of a chance at all.

As you say - you have A librfcum library, but the config step didnt seem to find it, so that means Ruby mkmf tools could not identify it (perhaps related to the architecture question).

Cheers.

Piers,

I do have 64 bit Solaris. I just tried 32 bit in the spirit of leaving no stone unturned.

Tried to use 'cc' that comes with Solaris 8/9 and that resulted in:

It's probably easier using a Linux machine. I will give that a try when I get the bandwidth next time.

Thanks for all your help.

Sri

I'm sorry - I really can't say why you would be gettin gthese problems, as I am unfamilir with the architecture.

Have you thought of using sapnwrfc ?

I didn't try the sapnwrfc. I assume I need a Netweaver running for this. Right!

Can you direct me to the 101 on sapnwrfc?

Sri

sapnwrfc is backwardly compatible (to an extent) - you shouldn't have any trouble.

/people/piers.harding/blog/2007/02/28/netweaver-rfc-gives-the-next-generation-ruby-and-perl-connectors

And then all the documentation with the source distributions etc.

Cheers.
