Hi Distinguished Pythoneers, Sorry if this Email is too verbose or unstructured ... (blame: blood sugar is dropping and I'm in need of some dinner!)
I've been set the task of creating a 64 bit Intel build of Python 2.5 that supports the EM64T functionality in our research groups new machines which are both running OS X 10.4.8. Intel Core 2 Duo laptop: Machine Name: Mac Machine Model: MacBookPro2,2 Processor Name: Intel Core 2 Duo Processor Speed: 2.33 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 4 MB Memory: 2 GB Bus Speed: 667 MHz Xserve Quad Xeon: Machine Name: Xserve Machine Model: Xserve1,1 Processor Name: Dual-Core Intel Xeon Processor Speed: 3 GHz Number Of Processors: 2 Total Number Of Cores: 4 L2 Cache (per processor): 4 MB Memory: 16 GB Bus Speed: 1.33 GHz The usual Python 2.5 build (http://www.python.org/ftp/python/2.5/ python-2.5-macosx.dmg) I believe is just 32 bit Universal ... we don't need a Universal build but 32 bits just doesn't cut it (the proverbial mustard) so to speak. I believe just a command line Python would be fine that supports 64 bit (as we need to interface to a MySQL database with multi-gigabytes of data). So far we've tried a source base build (http://www.python.org/ftp/ python/2.5/Python-2.5.tgz) 1) with the default configure (default options) which just leads to a 32 bit Intel python executable: $ file python.exe python.exe: Mach-O executable i386 2) and then a few different flags on configure (I've no idea where my "partner in crime" got these from! I though -march was the new flag!): /configure OPT="-fast -Wall \ > -Wstrict-prototypes -fno-common -fPIC \ > -isysroot /Developer/SDKs/MacOSX10.4u.sdk \ > -arch x86_64" \ > LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk,\ > -headerpad_max_install_names -arch x86_64" While the configure runs ... the make eventually fails with: /Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/ CoreServices.framework/Frameworks/CarbonCore.framework/Headers/fp.h: 1338: error: 'SIGDIGLEN' undeclared here (not in a function) make: *** [Python/mactoolboxglue.o] Error 1 I've seen this SIGDIGLEN error about before ... probably relates to the conditional in fp.h not handling an unknown CPU_TARGET : #if TARGET_CPU_PPC || TARGET_CPU_X86 #define SIGDIGLEN 36 #elif TARGET_CPU_68K #define SIGDIGLEN 20 #endif Anyway, I expect the fundamental problem relates to Carbon not being 64-bit ready (until Leopard). I guess I just want to do a basic ("Unix-"-y) command line build of Python 2.5 that handles the EM64T functionality in the chips we have in our machines. Do I have to wait until Leopard??? Thanks for any pointers (or any other structures 8-) ). Harry. Extinguished Pythoneer (temporarily) ------------------------------------------------------------------------ ---- Dr. Harold W.
