Comment on Build and install cx_Oracle on MacOS X Leopard Intel by Robert Myers

Robert Myers — Tue, 17 Nov 2009 17:00:18 +0000

I had the ‘Symbol not found: ___divdi3′ problem as well, using Python 2.6.2 from python.org. The problem is that python itself is not built correctly? (not linked against libgcc dynamically – I’m not exactly sure) The solution is to link cx_Oracle.so against gcc with the flag

-lgcc

Place that right after ‘-lclntsh’ and the build should work and run without issues. The full gcc line I used was:

gcc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g -bundle -undefined dynamic_lookup build/temp.macosx-10.3-i386-2.6-10g/cx_Oracle.o -L/usr/lib -L/oracle_home/lib -lclntsh -lgcc -o build/lib.macosx-10.3-i386-2.6-10g/cx_Oracle.so

jaythomas is it possible you did not change the 2.5 in the command? Did you use the command as brad had it or did you get it from the results of the build?

Using Stackless 2.6.2 on a MacbookPro OSX Leopard. I was using virtualenv and simply ran easy_install cx_Oracle.

When this was done I had the __divdi3 problem per above.

I then went to another directory and downloaded the cx_oracle tar file per above. Created a subdirectory bob. Added bob to my PYTHONPATH (export PYTHONPATH=${PYTHONPATH}:./bob/) then ran:

python setup.py install –install-lib ./bob/

looking back in the output I see.
creating build/lib.macosx-10.3-fat-2.6-10g
gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g -bundle -undefined dynamic_lookup build/temp.macosx-10.3-fat-2.6-10g/cx_Oracle.o -L/Applications/instantclient/ohome/lib -L/Applications/instantclient/ohome -lclntsh -o build/lib.macosx-10.3-fat-2.6-10g/cx_Oracle.so

Looking in the bob directory there is an egg that is 102871 bytes long.

running this gcc command with “-arch ppc” taken out…
then rerunning my install to ./bob/… I get an egg now that is 51521 bytes long.

I then moved that egg to where easy_install put the bad egg

It a bit longer than it needs to be. But I wanted to make sure I was not introducing additional path problems etc.

For what it’s worth, I didn’t run into the Symbol not found: ___divdi3 problem until I tried installing python 2.6, and Yaroslav’s fix did not work for me.

When I reverted back to 2.5 (that is, the OSX default install), the problem went away.

I’m trying to get cx_Oracle-5.0.1 built against the instant client 10.2.0.4 (instantclient-basic-10.2.0.4.0-macosx-x86.zip and instantclient-sdk-10.2.0.4.0-macosx-x86.zip) on OS X 10.5.8 with Python 2.5.1, and I’m running across the same problem as Yaroslav Bulatov.

Luckily, his suggestion works for me. After running “python setup.py build” look for the call to gcc, remove the “-arch ppc” option, and run that command again. For me this was:

gcc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g -bundle -undefined dynamic_lookup build/temp.macosx-10.3-fat-2.5-10g/cx_Oracle.o -L$ORACLE_HOME/lib -L$ORACLE_HOME -lclntsh -o build/lib.macosx-10.3-fat-2.5-10g/cx_Oracle.so

Then running “python setup.py install” works as expected.

Thanks for the article and the comments!

Comment on Snow Leopard and Java compatibility issues by Jem

Jem — Wed, 09 Sep 2009 15:33:43 +0000

I had exactly the same problems with Java… I think that they should simply had left 1.4 & 1.5 as they were – changing them to symbolic links to 1.6 is just *wrong*.

BTW… the installation does free up some space (some 5GB, it is said) but the reason you saw such a dramatic increase in your free space is also down to the use of ‘metric’ sizes in Snow Leopard.

Comment on Porting ZMPP to Android in one day by Wei-ju Wu

Wei-ju Wu — Sat, 06 Jun 2009 14:43:27 +0000

Yeah, I plan to put the sourcecode out together with the Android Market release once it gets in a form that other people can use it.
In principle it’s working, but it is not a full Android integration yet.

Is the code for the Android port available somewhere, or do you plan to publish it? I don’t see it in the SVN repository on SoureForge.

Hi,

I have created an updated HowTo for version 5.0 of the cx_Oracle module.

Comment on A new ZMPP design by codingnaked

codingnaked — Thu, 18 Dec 2008 05:13:11 +0000

Yes, I actually have the plan to pick it up again over the Christmas holidays. There is still some considerable work to do, especially that dreaded V6 model

Thank you for everything you have done to make ZMPP better.
