Thanks Alberto,
This is a very promising approach.
I tried to modify the Makefile in src/interfaces/libpq/Makefile and I replaced the occurrences of -lssl and -lcrypto
with:
/root/rothsoft/libressl-3.6.1/ssl/.libs/libssl.a
/root/rothsoft/libressl-3.6.1/crypto/.libs/libcrypto.a
The compilation process is OK but when I tried to execute the test app I receive a link error:
Error loading DLL: /root/rothsoft/engines/postgreSQL/Linux/postgresql/libpq.so: undefined symbol: GENERAL_NAME_free
GENERAL_NAME_free usually means that libcrypto is missed.
Any help would be really appreciated.
Please note that I also tried with:
-l:/root/rothsoft/libressl-3.6.1/ssl/.libs/libssl.a
-l:/root/rothsoft/libressl-3.6.1/crypto/.libs/libcrypto.a
Thanks,
Marco
