curl - Static linking libcurl using c

Question

I am using Libcurl in my application with C and GNU compiler on a linux machine. Application also uses OpenSSL libraries and some other libraries. I am trying to statically link the libraries, except for lcurl linking with other libraries works fine.

I am trying to compile as below.

gcc -static -I. -o test test.c -lz -lssl -lcrypto -lcurl

Am I doing anything wrong? Is there a way to force static linking of some librairies (libc for exemple) ?

Answer 1

Libcurl is itself linked against a ton of other libraries, most of which aren't included in your compile command line. For instance, mine (on Debian Squeeze) links against:

• libc
• libcom_err
• libcrypto
• libdl
• libgcrypt
• libgnutls
• libgpg-error
• libgssapi_krb5
• libidn
• libk5crypto
• libkeyutils
• libkrb5
• libkrb5support
• liblber-2.4
• libldap_r-2.4
• libpthread
• libresolv
• librt
• libsasl2
• libssh2
• libssl
• libtasn1
• libz

(You can get a similar list for yourself by running ldd on the library on Linux, or otool -L on Darwin.)
