RE: why does php compile looks for wrong curl

["Christine Ross" <cross@xxxxxxxx>]

Thank you for the ideas.  I was able to get the correct LDD after setting ldflags and ld_library_path.

Do an 'ldd' on the PHP binary using the same (clean) shell environment
you use when starting Apache, making sure you have no LD_* variables
set in your env. Does it still come up with the "libcurl/7.19.5"-path?

This tells you which library the binary has linked to, i.e. which
RUN_PATH the binary is built with. You can override this using things
like LD_LIBRARY_PATH in your shell environment, but it doesn't change
the RUN_PATH in the binary.

Try adding CFLAGS including your curl to your build, e.g.

  CFLAGS='-L/usr/local/curl-7.19.5/lib -R/usr/local/curl-7.19.5/lib'; export CFLAGS

I've used it with success before on both Solaris8 and 10 (sparc,
SunCC) to get a proper RUN_PATH in the binary.

Failing all else, you might try use a nifty little tool called
'chrpath' to brute-force a new RPATH in your binary:

  http://linux.die.net/man/1/chrpath

Caveat: I've only used it on linux x86; don't know if it'll work on SPARC.
