Re: [Openexr-devel] undefined symbol link error

[Scott Frankel]

Right.  That got rid of the previous error ... but gained me 27 new  
ones.

Here's a question:  how exactly should the lib*.a & .la files be used?
The install step produced msgs referring to libtool.  Is that just for  
dynamic
linking?  I turned off the enable-share option in the config.

Many of the new errors I'm getting are from undeclared symbols; i.e.:
::asinf.  They originate in ImathMath.h, included in ImathVec.h.  Is  
there
a lib file that's not getting read properly, where asinf, atanf, &c.  
are declared?

Another possibility:  do I need to have fltk installed to properly  
install the
openEXR material?  I'm getting msgs and errors during 'make' and 'make  
install',
like:

        make[1]: Nothing to be done for `all'.
        make[1]: Nothing to be done for `all-am'.

and

        make[3]: *** No rule to make target `install-exec-hook'.  Stop.
        make[2]: *** [install-exec-am] Error 2
        make[1]: *** [install-am] Error 2
        make: *** [install-recursive] Error 1


Thanks for your suggestions.
Scott
