problem about static link libssl.a libcrypto.a to my application(linux platform)

[jj Zhu]

    It goes well when dynamic linking, using command like this:
      gcc -lssl error.o wrapsock.o wrapunix.o driverUtility.o driver.o -o driver

then I want to link openssl lib statically so I do not need to install openssl when  I run my application on another linux platform,but after I change the command into this:

      gcc -static /usr/lib/libssl.a /usr/lib/libcrypto.a error.o wrapsock.o  wrapunix.o driverUtility.o driver.o -o driver

      I get these compile errors:
driver.o: In function `logout':
driver.c:(.text+0x16e): undefined reference to `SSL_library_init'
driver.c:(.text+0x173): undefined reference to `SSL_load_error_strings'
driver.c:(.text+0x178): undefined reference to `SSLv23_client_method'
driver.c:(.text+0x180): undefined reference to `SSL_CTX_new'
driver.c:(.text+0x1b8): undefined reference to `SSL_new'
driver.c:(.text+0x1fa): undefined reference to `SSL_set_fd'
driver.c:(.text+0x232): undefined reference to `SSL_connect'
driver.c:(.text+0x329): undefined reference to `SSL_write'
driver.c:(.text+0x378): undefined reference to `SSL_shutdown'
driver.c:(.text+0x38c): undefined reference to `SSL_free'
driver.c:(.text+0x39a): undefined reference to `SSL_CTX_free'
       I checked and found that there does exist /usr/lib/libssl.a /usr/lib/libcrypto.a in my system, I don't konw why? Is there probably something wrong with the /usr/lib/libssl.a /usr/lib/libcrypto.a? Can someone tell me how to statically link openssl lib to my application?

your link order is wrong.  the libraries have to come after all your
source files.

you also shouldnt use full paths.  use the normal -lssl style -- the
-static flag will select the right library.
