I first tried unixODBC in order to get ODBC functionality on my FreeBSD 4.2 box with PHP 4.0.3 on Apache 1.3.14. It didn't work too well, and I kept getting an error about undefined symbols like pthread_mutex_init or something when trying to run command-line sample applications. So someone suggested I use iODBC instead and I responded: Okay, I uninstalled unixODBC and tried iODBC ( I actually began to try it before, but then thought of something that might work on unixODBC, so I went back to it ). Now iODBC's odbctest application works with myODBC installed. However, after I recompile PHP with iodbc parameters, I try to run the odbc_connect function. If I misspell the DSN or use a non-existent one, I will get the following message: Warning: SQL error: [iODBC][Driver Manager]Data source name not found and no default driver specified. Driver could not be loaded, SQL state IM002 in SQLConnect Now, if I spell the defined DSN correctly and reload the page, the application just hangs. If I look at my error logs I see this: /usr/libexec/ld-elf.so.1: /usr/local/lib/libmyodbc.so: Undefined symbol "pthread_mutex_init" Once for every time I reload the page. This is odd, because this was a problem message I was receiving when testing unixODBC on the command line. After I installed iODBC, the command-line application was able to connect and query perfectly! So what gives? Why does one application work and another does not? I set the following environment vars - some may not make sense, but I've been trying everything: $EnvVars["LD_LIBRARY_PATH"] = "/usr/local/lib:/usr/include"; $EnvVars["LD_RUN_PATH"] = "/usr/local/lib:/usr/include"; $EnvVars["ODBCINI"] = "/usr/local/src/odbcsdk/doc/odbc.ini"; $EnvVars["PATH"] = "/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/bin:/usr/X11R6/bin:/hom e/suroot/bin:/usr/libexec:/usr/include"; foreach($EnvVars as $Key => $Val) { putenv("$Key=$Val"); $HTTP_ENV_VARS["$Key"] = $Val; } I can see via phpinfo() that they are getting set.
