[Openexr-user] help needed in installing open exr

[Archana Gopalan]

Hi,
I am trying to install open exr-1.6.1

I have installed all the necessary basic packages for cygwin.

The first command ./configure worked fine.

When I run 'make', I get the following error.

Please guide me as to what to do.

Regards,
Archana

Hi Archana,

It looks like your build is unable to find the
"ilmbase" package, which OpenEXR is dependent on. I am
not so familiar with cygwin, but this is how I

setenv BUILD_DIR /home/darby/build
cd $BUILD_DIR
gzcat ilmbase-1.0.1.tar.gz | tar xvf -
cd ilmbase-1.0.1
./configure --prefix=$BUILD_DIR
make && make install
cd ..
gzcat openexr-1.6.1.tar.gz | tar xvf -
cd openexr-1.6.1
./configure --prefix=$BUILD_DIR \

PKG_CONFIG_PATH=$BUILD_DIR/lib/pkgconfig

make && make install

The variable BUILD_DIR is just the directory where I
am building the software. Note that you need to build
ilmbase first, and then OpenEXR. You also need to tell
OpenEXR where to find ilmbase, which in this case I am
doing with the PKG_CONFIG_PATH variable. If pkg-config
isn't available in cygwin, you can also pass the
command-line argument --with-ilmbase-prefix=$BUILD_DIR
to the configure script.

It looks to me like make didn't first build toFloat. Has anyone on this
list ever tried building OpenEXR on Windows under cygwin? I haven't
tried that myself.

./configure --prefix=$BUILD_DIR \

./configure \
--prefix=$BUILD_DIR \
PKG_CONFIG_PATH=$BUILD_DIR/lib/pkgconfig \

The LD_LIBRARY_PATH being necessary to run the ilmbase
test program.
