Hi all: I tried installing the Qhull package which is an optional package on the list at http://www.sagemath.org/packages/optional/, but i got the error below. It appears that /usr/include/float.h can't be found, but i *do* have that file. Any suggestions for how to install Qhull successfully?
Thanks.

Describe your computer, operating system, etc. If you want to try to fix the problem yourself, *don't* just cd to /Applications/sage/spkg/build/qhull-2010.1 and type 'make check' or whatever is appropriate. Instead, the following commands setup all environment variables correctly and load a subshell for you to debug the error: (cd '/Applications/sage/spkg/build/qhull-2010.1' && '/Applications/ sage/sage' -sh) When you are done debugging, you can type "exit" to leave the subshell. raichev@wujarch-l~> -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
