Yet another possibly related problem: when installing qhull from a script it errors out with ... cd lib && ln -f -s libqhull_r.so.7.2.0 libqhull_r.so
=================================================== == If user_eg fails to link on MinGW or Cygwin, use == "make SO=dll" and copy lib/libqhull_r.dll to bin/ == Otherwise if user_eg fails to link, switch to -lqhullstatic_r =================================================== gcc -o bin/user_eg src/user_eg/user_eg_r.o -O3 -ansi -Isrc -fpic -Wall -Wcast-qual -Wextra -Wwrite-strings -Wshadow -Llib -lqhull_r -lm bin/qconvex QH6075 qhull input error: short input file.

If I try to install qhull after that in an interactive terminal everything is OK. The line "While executing: | qconvex" suggests that perhaps there are again issues with pipes. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
