FIPS_mode_set(1) always returns false

[Taraniteja Vishwanatha]

Hey guys,

I have built openssl-FIPS module (1.2.4) for iOS as per the instructions in
the user guide 1.2. I have included the headers and libraries in my test
app. I call FIPS_mode_set(1) in the app and it always returns false.
Is it because 1.2.4 module supports iOS 5.0 and I am using iOS 5.1?
Also, are 1.2.4 User guide instructions valid to build 2.0 module which
supports iOS 5.1?

Thank you,
Tarani
