I tried building the building the cudaminer 417 from scratch and while doing ./configure I noticed this:
checking for curl-config... no
checking whether libcurl is usable... no
configure: error: Missing required libcurl >= 7.10.1
mads@Adria:~/cudaminer-src/cudaminer-src-2013.04.17$ curl --version
curl 7.26.0 (i486-pc-linux-gnu) libcurl/7.26.0 OpenSSL/1.0.1e zlib/1.2.7 libidn/1.25 libssh2/1.4.2 librtmp/2.3
Is that expected behavior? Because it looks a little wrong.
