Wow, has it really been that long since I’ve written here? I really need to do better. So tonight I ran into an interesting issue this evening in configuring PECL memcache to run on my Macintosh. To give you a bit of background, I use the built-in copy of Apache, but with PHP (current 5.2.8) compiled from source since the version in Leopard is old and I needed some things that it didn’t provice. After that was installed with no problems, I went to the ext/memcache-3.0.4 directory to compile memcache as so: phpize ./configure make make install Then added it to php.ini as an extension and restarted apache. But it didn’t work. The information returned from phpinfo() still indicated it had not been installed. So I checked the logs and found this little gem: PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20060613/' - (null) in Unknown on line 0 Okay. WTF does that mean? While Googling around for an answer, I came across this page. According to it,it’s a strong indication that you’ve likely compiled against the wrong architecture! This is an indication that the shared extension is causing a segmentation fault. Fortunately, there is a solution - force configure to use the right architecture. make clean MACOSX_DEPLOYMENT_TARGET=10.5 CFLAGS="-arch x86_64 -g -Os -pipe -no-cpp-precomp" CCFLAGS="-arch x86_64 -g -Os -pipe" CXXFLAGS="-arch x86_64 -g -Os -pipe" LDFLAGS="-arch x86_64 -bind_at_load" ./configure make make install Now restart apache. You should have working memcache!
