Hi,
I have been attempting to install R-devel to check updated packages for
CRAN. After reading the relevant section in R Installation and
Administration, searching and a lot of unsuccessful fiddling with
"configure", I thought I might as well ask.

Platform: x86_64-pc-linux-gnu (64-bit)
Running under: Fedora 21 (Twenty One)

locale:
[1] LC_CTYPE=en_US.UTF-8       LC_NUMERIC=C
[3] LC_TIME=en_US.UTF-8        LC_COLLATE=en_US.UTF-8
[5] LC_MONETARY=en_US.UTF-8    LC_MESSAGES=en_US.UTF-8
[7] LC_PAPER=en_US.UTF-8       LC_NAME=C
[9] LC_ADDRESS=C               LC_TELEPHONE=C

configure hits the wall when checking for libcurl. I installed libcurl
v7.37.0 and while it is recognized, I have not succeeded in getting it

to

find curl.h (it's in /usr/include/curl/curl.h). R Installation ahd
Administration seems to suggest that the path information should be put

in

MkRules.local. However, that file is nowhere to be found. Neither can I
find any variable in "configure" that specifies where to look for

curl.h.

I'm sure that this is very simple, but if anyone can provide a method to
stop the:

...
checking curl/curl.h usability... no
checking curl/curl.h presence... no
checking for curl/curl.h... no
configure: error: libcurl >= 7.28.0 library and headers are required

with

support for https

error I would be most grateful.

This may be a little bit off topic for this list, since it is not an
issue with your package, but I'll try to answer anyway.

Also, a generic piece of advice: configure doesn't always get its error
messages precisely right. Sometimes it is useful to go through the
config.log and see exactly what program failed to compile with what error
message. It's not that unusual to see an include file test program failing
due to wrong compiler flags or libraries.

The header file /usr/include/curl/curl.h is provided by both the 32-bit
and 64-bit versions of libcurl-devel. I can reproduce your error if I
have libcurl-devel.i686 installed (which provides the header) but not
libcurl-devel.x86_64 (which is needed to compile the 64-bit version of
R). This gives me the following output:

checking for curl-config... /usr/bin/curl-config
checking libcurl version ... 7.37.0
Package libcurl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcurl' found
checking curl/curl.h usability... no
checking curl/curl.h presence... no
checking for curl/curl.h... no
configure: error: libcurl >= 7.28.0 library and headers are required
with support for https
