Ok, whith few modifications to fipsld++ i can now link to libcrypto.so
and libcrypto.a and applications are working correctly, but mine problem
still persists because if i would like to dlopen my shared library
compiled with static libcrypto.a and i'll try to run fips mode from that
library i get an error: 755413103 which, i have read, means that library
has an incorect digest and verification has failed. Now i found that
fips_premain_dso is used to generate/get this digest from library but it
does not generate or even does not output anything and it does not
matter if it is linux/QNX or whatever platform it is. Maybe i'm using it
wrong but could anubody tell me how to use this fips_premain_dso? I'm
using it like that:

LD_LIBRARY_PATH=/path/to/where/my/lib/is fips_premain_dso mylib.so

And that does not output anything.
