Dear all,
I am trying to upgrade R on Debian 3.16.0-4-amd64, as the default R version is
3.1.1 (2014). When I try to run ./configure on R-3.3.3, I get an error message
saying
...
checking for curl-config... /usr/local/bin/curl-config
checking libcurl version ... 7.53.1
checking curl/curl.h usability... yes
checking curl/curl.h presence... yes
checking for curl/curl.h... yes
checking if libcurl is version 7 and >= 7.28.0... yes
checking if libcurl supports https... no
configure: error: libcurl >= 7.28.0 library and headers are required with
support for https
I received the following advice from a senior Debian user:
"Encryption has gone through some growing pains lately, with older versions of
the standard encryption protocol being effectively black listed. (TLS v1.0 had
holes, now it must be TLS v1.1 or above).
So, whilst it says you have SSL, libcurl will be critical of the version and
say you don't (because the SSL version is black listed).
It is possible that updating libssl-dev, openssl-dev (or whatever they are
called) will make curl happy, because Debian might have updated their packages
to keep up with the times. You might need to uncomment the security updates in
/etc/apt/sources. OTOH, they might not... in which case you need to download
and build openssl yourself, and then build libcurl, making very sure it uses
your openssl and not the standard openssl. I do recall it is a pain to stop it
seeking out the standard openssl."
Following the above suggestions and some information I found online I installed
libcurl4-openssl-dev, but this hasn't solved the problem. I now am getting
further problems installing other packages (hyphy)
/etc/hyphy$ cmake .
cmake: /usr/local/lib/libcurl.so.4: no version information available (required
by cmake)
Segmentation fault
I am not sure whether the latter is related to some other installation fault
that occurred when I was trying to fix R, but I would rather get some advice
before proceeding any further, as I don't have enough experience to identify
and solve the problem directly.
Many thanks for any help!
All the best,
Lucio
