一、下載libcurl http://curl.haxx.se/download/curl-7.21.1.tar.gz 二、安裝 指定了安裝目錄 /usr/local/curl 注意：在這裡最好用預設的路徑 命令1: ./configure --prefix=/usr/local/curl該為命令：./configure 這樣，在編譯器的時候直接使用
gcc -o filename -Wall filename.c -lcurl 就不會出現編譯連結錯誤， 如果你的路徑改變了，那麼在編譯器時可能會比較麻煩。 結果： curl version: 7.21.1 Host setup: i686-pc-linux-gnu Install prefix: /usr/local/curl Compiler: gcc SSL support: enabled (OpenSSL) SSH support: no (--with-libssh2) zlib support: enabled krb4 support: no (--with-krb4*) GSSAPI support: no (--with-gssapi) SPNEGO support: no (--with-spnego) resolver: default (--enable-ares / --enable-threaded-resolver) ipv6 support: enabled IDN support: enabled Build libcurl: Shared=yes, Static=yes Built-in manual: enabled Verbose errors: enabled (--disable-verbose) SSPI support: no (--enable-sspi) ca cert bundle: /etc/ssl/certs/ca-certificates.crt ca cert path: no LDAP support: enabled (OpenLDAP) LDAPS support: enabled RTSP support: enabled RTMP support: no (--with-librtmp) Protocols: DICT FILE FTP FTPS HTTP HTTPS IMAP IMAPS LDAP LDAPS POP3 POP3S RTSP SMTP SMTPS TELNET TFTP 命令2：make 命令3：sudo make install 可以看到lib庫，已經安裝在 /usr/local/curl/lib ---------------------------------------------------------------------- Libraries have been installed in: /usr/local/curl/lib If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the `-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the `LD_RUN_PATH' environment variable during linking - use the `-Wl,-rpath -Wl,LIBDIR' linker flag - have your system administrator add LIBDIR to `/etc/ld.so.conf' See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages. 在安裝目錄下/usr/local/curl下會有四個目錄 bin include lib share 包含了所需的庫、標頭檔等
