I had a build issue with this package due to optimizations:
itterentropy-base.c:60:4: error: "The CPU Jitter random number generator must
not be compiled with optimizations. See documentation. Use the compiler switch
-O0 for compiling
jitterentropy-base.c."
#error "The CPU Jitter random number generator must not be compiled with
optimizations. See documentation. Use the compiler switch -O0 for compiling
jitterentropy-base.c."
^
I forced -O0 in the CFLAGS to fixes the issue.
Best regards,
Romain
