Hmm. What is produced is just a set of interfaces with some constants. I
can't see anything that results in a call to native code. I'm not sure
if this is something I've done wrong, a limitation of the early release
or something else.
I tried using a different header file with (hopefully) more functionality:
/opt/java/openjdk-12-panama-b0/bin/jextract \
-I include \
-I /usr/lib/gcc/x86_64-linux-gnu/7.3.0/include \
-I /usr/include/linux \
-t org.openssl \
include/openssl/crypto.h
and I get:
/usr/include/linux/time.h:10:8: error: redefinition of 'timespec'
/usr/include/linux/time.h:10:8: error: redefinition of 'timespec'
It isn't immediately obvious to me where timespec is redefined - else
I'd tweak the relevant header file.
