I have just tried to install curl to get https support.
To do that, I have followed the steps below:
1. Installation of openssl:
1.a. ./config --prefix=/my/openssl/path
1.b. make
1.c. make test
1.d. make install
2. Installation of curl
2.a. ./configure --prefix=/my/curl/path --with-ssl=/my/openssl/path/lib
2.b. make
2.c. make install
I have also prepend PATH with /my/curl/path/bin.
However, the error remains.
It seems that my version of curl (7.41.0) is not taken into acount because I have still this line in the error message:
User-Agent: curl/7.38.0
I tried to remove all previous of curl and libcurl but it does not change anything.
Could you help me?
