When compiling with glibc it will result in error:
1. #warning _FORTIFY_SOURCE requires compiling with optimization (-O)
[-Werror=cpp]
Fix this by compiling with optimization (-O2) by default.
2. jitterentropy-base.c:(.text+0x39f8): undefined reference to `pthread_join'
Fix this by always linking pthread.
Others already said we can't switch to -O2, I'll just add some references.
At some point jitterentropy-library switched from -O0 to -O2:
3130cd99d7fa ("replace LSFR with SHA-3 256")
https://github.com/smuellerDD/jitterentropy-library/commit/3130cd99d7fa308c00cc2c4be6c5aa20c002be56
That was however explicitly changed back later with the:
20184e97af8f ("Compile Jitter RNG without optimizations")
https://github.com/smuellerDD/jitterentropy-library/commit/20184e97af8f227cc0787c4155ff4f3b2b7f1fe3
Also jitterentropy-rngd uses -O0:
f1bc39ae713a ("use -O0")
https://github.com/smuellerDD/jitterentropy-rngd/commit/f1bc39ae713a253077b0c47b4a1ad53f32bbfce0
