Re: [Openexr-devel] Bug in configure script for openexr-2.1.0 on ubuntu 12.0.4 LTS

[Christopher Horvath]

It is not installed on the system I'm on, and I don't have permission to install it, so I put it in my staging area with everything else.

Either way, though, it's clear that the LDFLAGS and CFLAGS passed into the configure script are not being used during compilation.

Hey, 

I don't have a linux box to hand, I'll need to reinstall the autoconf tool on this Mac first.  However, a quick glance at the configure.ac doesn't seem to indicate that you could set the location of zlib explicitly, rather it assumes it is on the system path. Is it not in your case?

Howdy folks.

I'm building openexr-2.1.0 in a non-standard location, on ubuntu 12.0.4 LTS.  I have an environment variable, EMLDNEEDS_ROOT, which is set to the install location for everything, using --prefix. I have a build of libz in this location as well. Here's my config line:

./configure --prefix=$EMLDNEEDS_ROOT --with-ilmbase-prefix=$EMLDNEEDS_ROOT --with-pic --enable-static --disable-shared LDFLAGS=-L$EMLDNEEDS_ROOT/lib CFLAGS=-I$EMLDNEEDS_ROOT/include

The bug is that it doesn't seem to be respecting LDFLAGS or CFLAGS when building, specifically with respect to libz. An example error:

I can fix this by futzing with the makefiles directly, but it does seem like a build bug.

I think this situation absolutely requires that a really futile and stupid gesture be done on somebody's part. And we're just the guys to do it.
