Openlink/PHP4 problems

I'm trying to build Apache/PHP4/Openlink. Here are the vital statistics - IBM RS6000, AIX 4.2.1 PowerPC, PHP4 CVS version, Apache 1.3.11. I have Openlink set up and talking to my database via odbctest. I have compiled PHP4 using --with-openlink (adding --with-iodbc=/path/to/iodbc doesn't seem to make any difference). The LIBPATH environment variable is pointing to /usr/local/openlink/lib. When I compile Apache, I get the following error message: ./gen_test_char >test_char.h Could not load program ./gen_test_char /usr/local/openlink/lib/libiodbc.a is not executable or not in correct XCOFF format Could not load library libiodbc.a Error was: Exec format error make: The error code from the last command is 255. Now this looks like the libiodbc.a file has some problems (BTW, the file is indeed there, and seems to have the proper permissions). So I changed LIBPATH to point to /usr/local/lib, where I have the version of libiodbc.a that I compiled from the libiodbc-2.50.3 package. I can get then get Apache to compile properly, but then I get core dumps in Apache when trying to access the database from a PHP script. I suspect that the iodbc that I compiled is the problem here, since I get coredumps in odbctest when using the version of this program from the libiodbc-2.50.3 directory. In fact, a comparison of the backtraces from Apache & odbctest looks very similar to my (untrained) eye. So I guess this boils down to a couple of questions, which now seem kinda off-topic (sorry): 1. Is the problem with compiling Apache against the Openlink version of libiodbc.a easily solved? If so, then maybe that's the easiest way to solve this. I'm sure it's possible that I downloaded the wrong version of the client components, though I believe I did get the ones for AIX 4.2 Power PC. 2. Am I doing something wrong when installing iODBC-2.50.3 that's causing the coredumps? All I did there was unpack the tarball, run ./configure, ./make, ./make install. Not much to screw up - is there? Any advice would be greatly appreciated, Brian
