initially I tried to install via git as described here http://trac.sagemath.org/wiki/Cygwin64Port but, because I have a very poor internet connection behind some company firewalls I dit not suceed with git clone git://trac.sagemath.org/sage.git. So I downloaded sage-6.7.tar.gz <ftp://ftp.fu-berlin.de/unix/misc/sage/src/sage-6.7.tar.gz> from ftp://ftp.fu-berlin.de/unix/misc/sage/src/index.html Annother problem is taht I don have admin rights so I installed cygwin not on C:\cygwin But I have a custom path like C:\XXX\cygwin64. After your comment above I recognized, that I had not installed all the necessary development packages. After I installed them I succeeded up to the buliding pf python. There I got an error. But after rebasing as described in http://trac.sagemath.org/wiki/Cygwin64Port I even got to the point where cygwin tried to build sage It says cd /home/USERXX/sage-6.7/build The last successfull build was building 'sage.ext.interpreters.wrapper_el' extension but then an error occured:

Does it make sense to try on an clean Cywin32 on C:\cygwin\? Are there less problems ? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
