Huge problem gettng MySQLdb to work on my mac mini running Macosx10.5 Leopard

P: n/a
Hi all,

I have a mac mini running maocosx 10.5 leopard I want to deploy a
django project on. My backend is MySQL, and I have it running as a 64-
bit app. Of course, apache2 is also running as 64-bit.

MySQLdb installs with the usual warnings after applying the various
patches I found here and there. These patches consist of altering
_mysql.c and site.cfg.

Basically, my problem boils down to this:

File "<stdin>", line 1, in <module>
File "build/bdist.macosx-10.5-i386/egg/MySQLdb/__init__.py", line
19, in <module>
File "build/bdist.macosx-10.5-i386/egg/_mysql.py", line 7, in
<module>
File "build/bdist.macosx-10.5-i386/egg/_mysql.py", line 6, in
__bootstrap__
ImportError: dynamic module does not define init function (init_mysql)
Has anyone solved this? I been hunting around for 2 weeks now, and my
deadline is looming grimly on the horizon :)

Geert,

I've not seen this issue myself, however, you might get a little more luck
asking over on the MySQLdb mailing list as this seems to be more an issue
with the db than your python code. It might be worth posting your question
there too as it'll heighten your chances of finding someone who knows
MySQLdb inside out.

Cheers,

Robert

Thanks, Robert. I'm on the MySQLdb list, and am working on a solution.
And I've subscribed to the list you gave.

There is a macpython list that you can consult athttp://www.nabble.com/Python---pythonmac-sig-f2970.html
Just wanted to let you know that I've solved my problem. The solution
is to compile mysql using

MACOSX_DEPLOYMENT_TARGET=10.5 \
CFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
LDFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
CXXFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
./configure --disable-dependency-tracking --enable-thread-safe-client
--prefix=/usr/local/mysql

You then go this way to get it running on your machine:

Then reinstall MySQLdb. Magic!

I just run the django dev server, but moving to apache through
mod_wsgi brings a well-known but less than comforting complaint:

Do the gcc compiler flags when building and linking the .so file show

Have you empty the Python egg cache to make sure it isn't an older

Hi all,

GOT IT!

I have every running now. So, to sum it all up:

I'm on a new intel mac with a 64-bit capable processor running macosx
10.5.2.

I have httpd (apache2) running as a 64 bit app, which it would of
course on a 64-bit machine. Activity monitor confirms this.

I compiled mysql from source, configured as stated below:

MACOSX_DEPLOYMENT_TARGET=10.5 \
CFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
LDFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
CXXFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
./configure --disable-dependency-tracking --enable-thread-safe-
client
--prefix=/usr/local/mysql

Then came mod_wsgi, just out of the box.

Then came MySQLdb.

Extracted the tar, then edited _mysql.c. Commented lines 37 - 39:

//#ifndef uint
//#define uint unsigned int
//#endif

and changed this:
uint port = MYSQL_PORT;
uint client_flag = 0;

to this:
unsigned int port = MYSQL_PORT;
unsigned int client_flag = 0;

on lines 484 and 485

Then - but I don't know if this is really (always) necessary, in
site.cfg I changed Threadsafe = True to False.

I set the ARCHFLAGS, but I don't think this helped one inch.

ARCHFLAGS='-arch ppc -arch ppc64 -arch i386 -arch x86_64'
OK. So then I went sudo python setup.py build. (I realise that the
sudo isn't required just to do a build)

There, I noticed this:

_mysql.o -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64

You see, here _mysql.o is being created. If you do file _mysql.o, you
get:

/Users/geert/Desktop/MySQL-python-1.2.2/build/temp.macosx-10.5-
i386-2.5/_mysql.o: Mach-O universal binary with 4 architectures

i386-2.5/_mysql.o (for architecture ppc64): Mach-O 64-bit object ppc64

which is ok.

But, strangely, when _mysql.so is created in the next step, gcc
doesn't add all the arch flags:

gcc -Wl,-F. -bundle -undefined dynamic_lookup -arch i386 -arch ppc
build/temp.macosx-10.5-i386-2.5/_mysql.o -L/usr/local/mysql/lib/mysql -
lmysqlclient -lz -lm -o build/lib.macosx-10.5-i386-2.5/_mysql.so

and you end up with this:

which is most definitely NOT ok.

So I did this:

sudo gcc -Wl,-F. -bundle -undefined dynamic_lookup -arch ppc -arch
ppc64 -arch i386 -arch x86_64 build/temp.macosx-10.5-i386-2.5/_mysql.o
-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -o build/
lib.macosx-10.5-i386-2.5/_mysql.so

adding the arch flags myself, and running gcc again, under sudo.

and lo and behold....

Well, it only took 20 years off my life span and all the hairs on my

There is a macpython list that you can consult athttp://www.nabble.com/Python---pythonmac-sig-f2970.html
Just wanted to let you know that I've solved my problem. The solution
is to compile mysql using
MACOSX_DEPLOYMENT_TARGET=10.5 \
CFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
LDFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
CXXFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
./configure --disable-dependency-tracking --enable-thread-safe-client
--prefix=/usr/local/mysql
You then go this way to get it running on your machine:
http://hivelogic.com/articles/instal...l-on-mac-os-x/
Then reinstall MySQLdb. Magic!

Did you again confirm that running:
file /Library/WebServer/.python-eggs/MySQL_python-1.2.2-py2.5-
macosx-10.5-i386.egg-tmp/_mysql.so
shows the .so having the required architectures, specifically what
Apache runs as (eg. x86_64)?
Do the gcc compiler flags when building and linking the .so file show
all the architecture flags?
Have you empty the Python egg cache to make sure it isn't an older
compiled version?

Hi all,

GOT IT!

I have every running now. So, to sum it all up:

I'm on a new intel mac with a 64-bit capable processor running macosx
10.5.2.

I have httpd (apache2) running as a 64 bit app, which it would of
course on a 64-bit machine. Activity monitor confirms this.

I compiled mysql from source, configured as stated below:

MACOSX_DEPLOYMENT_TARGET=10.5 \
CFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
LDFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
CXXFLAGS='-arch i386 -arch x86_64 -arch ppc7400 -arch ppc64' \
./configure --disable-dependency-tracking --enable-thread-safe-
client
--prefix=/usr/local/mysql

Then camemod_wsgi, just out of the box.

Then came MySQLdb.

Extracted the tar, then edited _mysql.c. Commented lines 37 - 39:

//#ifndef uint
//#define uint unsigned int
//#endif

and changed this:
uint port = MYSQL_PORT;
uint client_flag = 0;

to this:
unsigned int port = MYSQL_PORT;
unsigned int client_flag = 0;

on lines 484 and 485

Then - but I don't know if this is really (always) necessary, in
site.cfg I changed Threadsafe = True to False.

I set the ARCHFLAGS, but I don't think this helped one inch.

ARCHFLAGS='-arch ppc -arch ppc64 -arch i386 -arch x86_64'

OK. So then I went sudo python setup.py build. (I realise that the
sudo isn't required just to do a build)

There, I noticed this:

creating build/temp.macosx-10.5-i386-2.5
gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-
madd -fno-common -dynamic -DNDEBUG -g -Os -Wall -Wstrict-prototypes -

_mysql.o -arch i386 -arch x86_64 -arch ppc7400 -arch ppc64

You see, here _mysql.o is being created. If you do file _mysql.o, you
get:

i386-2.5/_mysql.o: Mach-O universal binary with 4 architectures

which is ok.

But, strangely, when _mysql.so is created in the next step, gcc
doesn't add all the arch flags:

gcc -Wl,-F. -bundle -undefined dynamic_lookup -arch i386 -arch ppc
build/temp.macosx-10.5-i386-2.5/_mysql.o -L/usr/local/mysql/lib/mysql -
lmysqlclient -lz -lm -o build/lib.macosx-10.5-i386-2.5/_mysql.so

and you end up with this:

So I did this:

adding the arch flags myself, and running gcc again, under sudo.

and lo and behold....

Well, it only took 20 years off my life span and all the hairs on my
head :)
I don't have access to MacOS X OS supplied Python 2.5 at moment, but
if distutils used by setup.py is ignoring ARCHFLAGS for the link then
that may be an issue with distutils. More likely though is that MySQL
setup.py is setting some option which is causing ARCHFLAGS to be
ignored.

Strange thing is I can't find ARCHFLAGS in original Python 2.5 source
I have, so checking it may be specific to MacOS X OS supplied Python.

Will need to check when I get home to my Leopard box.
