Fix compilation when NO_CURL is defined

dscho · spearce · commit ccfc02a30057 · 2007-10-15T21:59:40.000-04:00
There were a few places which did not cope well without curl. This fixes all of them. We still need to link against the walker.o part of the library as some parts of transport.o still call into there even though we don't have HTTP support enabled. If compiled with NO_CURL=1 we now get the following useful error message: $ git-fetch http://www.example.com/git error: git was compiled without libcurl support. fatal: Don't know how to fetch from http://www.example.com/git Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Shawn O.
