Hello,

I just updated OpenSSL from version 1.1.1 (Sept 2018) to 1.1.1g (Apr 2020).
When I compile TITAN from scratch, I got the following errors:

Int.o: In function `Common::int_val_t::operator-() const':
Int.cc:(.text+0x4c0): undefined reference to `BN_is_negative'
Int.o: In function `Common::int_val_t::operator-(Common::int_val_t const&) const':
Int.cc:(.text+0x9b9): undefined reference to `BN_is_negative'
Int.cc:(.text+0x9d1): undefined reference to `BN_is_negative'
Int.o: In function `Common::int_val_t::operator+(Common::int_val_t const&) const':
Int.cc:(.text+0xcb9): undefined reference to `BN_is_negative'
Int.cc:(.text+0xcd1): undefined reference to `BN_is_negative'
Int.o:Int.cc:(.text+0x159b): more undefined references to `BN_is_negative' follow
../common/openssl_version.o: In function `openssl_version_str':
openssl_version.c:(.text+0x3): undefined reference to `OpenSSL_version'

What is the lastest OpenSSL version supported by TITAN?

Thanks a lot,

Best Reagrds,

Yann

Are you sure that the correct header files were used during the compilation?

The 1.1.1 (Sept 2018) and 1.1.1g (Apr 2020) are ABI compatible, so no recompilation is needed to use the newer libraries.

The error message indicates that the object file were compiled with the header files of the 1.0.1 or older but try to link with 1.1.0 or newer

Hello Gabor,

Yes, I'm sure:
yann@Linux:~/dev/TTF0002_Its/scripts$ grep -i OPENSSL_VERSION_TEXT /usr/include/openssl/opensslv.h
# define OPENSSL_VERSION_TEXT "OpenSSL 1.1.1g 21 Apr 2020"

Hello Gabor,

I found the issue: the links to the share libraries libssl.so and libcrypto.so were not updated by the 'sudo make install' command from openssl1.1.1g.
My apologies for the inconveniences,

Yann
