OpenSSL Linux動態庫編譯

靜態庫編譯

????????????????./config?

????????????????make

????????????????make install

動態庫編譯

????????????????./config shared

????????????????make

????????????????make install

問題1）relocation R_AARCH64_ADR_PREL_PG_HI21 ? ? ? ? ? ? ?

之前編譯完成靜態庫，沒有清理干凈，出現問題

指令????./config shared && make

出錯

usr/bin/ld: libcrypto.a(gost_eng.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `stderr@@GLIBC_2.17' which may bind externally can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: libcrypto.a(gost_eng.o)(.text+0x4f0): unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol `stderr@@GLIBC_2.17'
/usr/bin/ld: final link failed: bad value
./stdio.h:477:1: error: 'gets' undeclared here (not in a function)
sed -i '/gets is a security hole/d' \
??? gettext-{runtime/gnulib-lib,tools/{gnulib-lib,libgettextpo}}/stdio.in.h

解決

make clean

./config shared

問題2）undefined reference to

undefined reference to `GENERAL_NAME_free@libcrypto.so.10'
undefined reference to `SSL_get_verify_result@libssl.so.10'
undefined reference to `SSL_CTX_set_default_passwd_cb_userdata@libssl.so.10'
undefined reference to `sk_num@libcrypto.so.10'
undefined reference to `SSL_CTX_ctrl@libssl.so.10'
undefined reference to `CRYPTO_set_dynlock_lock_callback@libcrypto.so.10'
undefined reference to `SSL_accept@libssl.so.10'
undefined reference to `SSL_new@libssl.so.10'
undefined reference to `SSL_CTX_set_cipher_list@libssl.so.10'

按照如上的make install操作，就可以解決該問題，否則需要通過-lssl -lcrypto鏈接指定的openssl庫，同時需要指定openssl的頭文件目錄
