When I run make, it seems to run fine but then fails when it tries to link the final application complaining that it can't find some files.
Some old versions of make that don't correctly put the compiled versions of the files in the functions directory into that same directory. Try running cp *.o functions and then re-running make to see if that helps. If it does, you should really upgrade to a recent version of GNU make.
When linking PHP, it complains about a number of undefined references.
Take a look at the link line and make sure that all of the appropriate libraries are being included at the end. Common ones that you might have missed are '-ldl' and any libraries required for any database support you included.
If you're linking with Apache 1.2.x, did you remember to add the appropriate information to the EXTRA_LIBS line of the Configuration file and re-rerun Apache's Configure script? See the installation chapter for more information.
Some people have also reported that they had to add '-ldl' immediately
I can't figure out how to build PHP with Apache 1.3.
This is actually quite easy. Follow these steps carefully:

I have followed all the steps to install the Apache module version on Unix, and my PHP scripts show up in my browser or I am being asked to save the file.

If this is what you see, you have found your problem. They may contain just spaces or other incorrect values, such as 'q()'. Change these lines to say:
The second possible problem should only be an issue on Red Hat 6.1 and 6.2. The apxs script Red Hat ships is broken. Look for this line:

I want to upgrade my PHP. Where can I find the ./configure line that was used to build my current PHP installation?
Either you look at config.nice file, in the source tree of your current PHP installation or, if this is not available, you simply run a

When building PHP with the GD library it either gives strange compile errors or segfaults on execution.
Make sure your GD library and PHP are linked against the same depending libraries (e.g. libpng).
When compiling PHP I seemingly get random errors, like it hangs. I'm using Solaris if that matters.
Using non-GNU utilities while compiling PHP may cause problems. Be
sure to use GNU tools in order to be certain that compiling PHP will
work. For example, on Solaris, using either the SunOS BSD-compatible
or Solaris versions of
