It doesn't usually happen on 10.13.6... Best guess is that somehow you are picking up an older library (e.g. in /usr/local/lib) even if you are using curl-config from a newer version.
The detective work needed could take off from config.log, region around this: configure:39937: checking if libcurl is version 7 and >= 7.22.0 configure:39966: gcc -arch x86_64 -o conftest -g -O2 -I/usr/local/include -L/usr/local/lib conftest.c -lcurl -lpcre -llzma -lbz2 -lz -licucore -lm -liconv >&5 configure:39966: $? = 0 configure:39966: ./conftest configure:39966: $? = 0 configure:39976: result: yes That's for a succesful build, a failed one will usually give more info including the failing program code. -pd > On 24 Feb 2019, at 22:45 , robin hankin <hankin.ro...@gmail.com> wrote: > > Hi, macos 10.13.6, trying to compile 3.6.0, revision 76152. > > ./configure > [snip] > > checking for curl-config... /Users/rhankin/anaconda3/bin/curl-config > checking libcurl version ... 7.63.0 > 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 >= 7.22.0... no > configure: error: libcurl >= 7.22.0 library and headers are required > with support for https > > if we have libcurl 7.63, as it says in the output, why the error?
