So I build openssl

./config
make
sudo make install
sudo ln -sf /usr/local/ssl/bin/openssl `which openssl`

I build curl

./configure --with-ssl 
make
make install

OpenSSL looks installed correctly:

openssl version
OpenSSL 1.0.1g 7 Apr 2014

however curl uses old openssl version (1.0.1f instead of 1.0.1g):

curl --version
curl 7.37.0 (x86_64-unknown-linux-gnu) libcurl/7.37.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 libssh2/1.4.3 librtmp/2.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp scp sftp smtp smtps telnet tftp 
Features: IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP 

how to make curl use new version?

I want to try the newest versions, because I am fighting with some strange openssl/curl bug #1 #2

Edit: I also tried ./configure --with-ssl=/usr/local/ssl/include/openssl, no success

Edit2: So far I also tried:

  • sudo ./configure --with-ssl --with-libssl-prefix=/usr/local/ssl
  • ./configure --with-ssl=/usr/local/ssl
  • PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig ./configure
  • PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig ./configure --with-ssl
  • PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig ./configure --with-ssl=/usr/local/ssl/include/openssl

no success...

You need to specify the directory where OpenSSL is installed (your symlink is neither necessary nor sufficient)

./configure --with-ssl=/usr/local/ssl

EDIT: Alternatively, you can set your PKG_CONFIG_PATH environment variable (as suggested by ./configure --help):

PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig ./configure

first option gives me configure: error: OpenSSL libs and/or directories were not found where specified! Please see my edit - there is no error with --with-ssl=/usr/local/ssl/include/openssl but old openssl is used. second option configures curl without HTTPS –  Peter Jun 2 at 10:50
    
I may have gotten the directories slightly wrong, I don't have access to a Linux box right now... Basically, your manual OpenSSL installation put a file openssl.pcsomewhere, you need to point PKG_CONFIG_PATH to the directory where that file is (and make sure you have pkg-config installed, of course). –  fkraiem Jun 2 at 11:06
    
PKG_CONFIG_PATH path is correct, I have pkg-config installed too, but somehow it doesn't work. without --with-ssl there is no HTTPS, with --with-sslit throws error configure: error: OpenSSL libs and/or directories were not found where specified! –  Peter Jun 2 at 11:07
    
Where and how did you install ssl ? Use the correct path. –  bodhi.zazen Jun 2 at 15:01
    
@bodhi.zazen I have install both Ubuntu package from official repositories and compiled openssl in /usr/local/ssl –  Peter Jun 5 at 8:25
