Description

I have installed cddlib-094j, or so I believe -- a header file reports 0.94i as the version.

I then tried:

export CPPFLAGS="-I/usr/local/include/cdd" 
./configure

The result:

checking cdd.h presence... yes
configure: WARNING: cdd.h: present but cannot be compiled
configure: WARNING: cdd.h:     check for missing prerequisite headers?
configure: WARNING: cdd.h: see the Autoconf documentation
configure: WARNING: cdd.h:     section "Present But Cannot Be Compiled" 
configure: WARNING: cdd.h: proceeding with the preprocessor's result
configure: WARNING: cdd.h: in the future, the compiler will take precedence
configure: WARNING:     ## --------------------------------- ##

What is going on? How to fix?

It seems that configure was giving just a warning (which is probably not a good sign). Anyway, it also created the Makefile.

I notice that the Makefile seemed to ignore the hint to use -I/usr/local/include/cdd; so I added it manually to the line defining CPPFLAGS.

Also the command for installing seemed to want to call ../mkinstalldir which does not exist on my computer; since the installation directories existed already, I just commented out the two lines in the install target.

And then I could build and install libgfan.a (in /usr/local).

Now CoCoALib compiles with GFan, but test-GFan1 give the same problem as mentioned in #1308.

The warning seems to be harmless: it worked on my Linux box, and it works on Anna's Mac despite the warnings.

We do note that CDD installs its header files in /usr/local/include/ whereas GFAN seems to want to find them in /usr/local/include/cdd/; frankly, the latter seems to be a nicer location.

I have modified the CoCoALib configure script so that it accepts with or without a final /cdd/.

Closing.
