Linking in OpenSSL libcrypto Statically
I have a C++ program which includes lots of libraries, including openssl libcrypto. In fact, the g++ switches are:

-lxml2 -lcrypto -lcurl etc.

The problem is that when I try to run it on a different flavor of Linux, it complains that it cannot load libcrypto.so.8. I did some research and learned about the difference between static and shared libraries, but can't quite figure out what steps to take to compile the libcrypto library in such a way that everything goes into the executable so that my program can be portable. Thanks in advance for any help you can give me.

err_get_lib

ERR_GET_LIB(3)							      OpenSSL							    ERR_GET_LIB(3)

NAME

       ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON - get library, function and reason code

LIBRARY

       libcrypto, -lcrypto

SYNOPSIS

	#include <openssl/err.h>

	int ERR_GET_LIB(unsigned long e);

	int ERR_GET_FUNC(unsigned long e);

	int ERR_GET_REASON(unsigned long e);

DESCRIPTION

       The error code returned by ERR_get_error() consists of a library number, function code and reason code. ERR_GET_LIB(), ERR_GET_FUNC() and
       ERR_GET_REASON() can be used to extract these.

       The library number and function code describe where the error occurred, the reason code is the information about what went wrong.

       Each sub-library of OpenSSL has a unique library number; function and reason codes are unique within each sub-library.  Note that different
       libraries may use the same value to signal different functions and reasons.

       ERR_R_... reason codes such as ERR_R_MALLOC_FAILURE are globally unique. However, when checking for sub-library specific reason codes, be
       sure to also compare the library number.

       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are macros.

RETURN VALUES

       The library number, function code and reason code respectively.

SEE ALSO

       openssl_err(3), ERR_get_error(3)

HISTORY

       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are available in all versions of SSLeay and OpenSSL.
