Sage 8.1 Mac OS 10.13.2 Build: Error installing package r-3.4.2.p0

[S. Diop]

Hi there!

I need help for this install error of Sage 8.1.

It seems that the culprit is "libcurl >= 7.22.0 library not found by the compiler".

Xcode 9.2 installed along with its command line tools version 9.2 for MacOS 10.13.2.

Best wishes!

The following package(s) may have failed to build (not necessarily

[Dima Pasechnik]

there is a conflict with your Anaconda installation. Make sure it not in your PATH.

It would also be great to get a confirmation that the external libcurl installation was picked up.

Namely, somewhere in the output of ./configure there should be a line

   curl-7.56.1 not installed (configure check)

(in the long list of the other Sage packages) - perhaps the version number is different there for you; 

most probably 7.55.1.

If this is indeed this case, you are probably hitting an R bug---indeed, these lines in your log:

[r-3.4.2.p0] checking libcurl version ... 7.55.1

[r-3.4.2.p0] checking curl/curl.h usability... yes

[r-3.4.2.p0] checking curl/curl.h presence... yes

[r-3.4.2.p0] checking for curl/curl.h... yes

[r-3.4.2.p0] checking if libcurl is version 7 and >= 7.22.0... no

look as if for R the version 7.55.1 is smaller than 7.22.0, which is kind of silly.

Thanks so much Dima,

I did disable anaconda, relaunch "make" and the build went through.

Best wishes
