error: invalid use of incomplete type ‘X509 {aka struct x509_st}’ about snort3

[cclements]

Manually specifying openssl-1.0 resolved this error:

./configure --with-openssl-includes=/usr/include/openssl-1.0/ --with-openssl-libraries=/usr/lib/openssl-1.0/

Thanks for posting the issue and resolution!

I have been asked to modify a program which does not compile with openssl 1.1. The error message is:

main.c: In function ‘do_signature’:
main.c:63:10: error: dereferencing pointer to incomplete type ‘X509 {aka struct x509_st}’
  memcpy(x->signature->data, sig_buf, sig_len);
          ^~
Makefile:54: recipe for target 'main.o' failed
make: *** [main.o] Error 1

I see where X509 is defined in a typedef in ossl_typ.h. Not being all that familiar with this software, I'd love a hint or a pointer to a hint which has the solution, please.

Thank you.

Im also stucked at this point even the openssl documentation is not helping me to find the structure which can help to know correct way to access.
