cryptopp 7.0.0 build log on 2018Q4 / FreeBSD 11.2 amd64
By default, the SIMD option is off, resulting in disabling certain features:
c++ -O2 -pipe -fstack-protector -fno-strict-aliasing -std=3Dc++11 -stdlib=
=3Dlibc++
-Wno-deprecated-declarations -fPIC -DNDEBUG -DCRYPTOPP_DISABLE_ASM
-DCRYPTOPP_DISABLE_SSE2 -DCRYPTOPP_DISABLE_SSSE3 -DCRYPTOPP_DISABLE_SSE4
-pthread -pipe -c misc.cpp
Thus, the `AlignedDeallocate` function does not get compiled.
Trying to use the shared object with `-lcryptopp` results in the above link=
er
error because `config.h` determines enabled features by the
`CRYPTOPP_DISABLE_*` macros.
In this case:
#if (CRYPTOPP_BOOL_X86 || CRYPTOPP_BOOL_X32 || CRYPTOPP_BOOL_X64 ||
CRYPTOPP_BOOL_PPC32 || CRYPTOPP_BOOL_PPC64) && !defined(CRYPTOPP_DISABLE_AS=
M)
#define CRYPTOPP_BOOL_ALIGN16 1
#else
#define CRYPTOPP_BOOL_ALIGN16 0
#endif
So a program linking against libcryptopp will think that
CRYPTOPP_BOOL_ALIGN16=3D1 while it was actually compiled (using default opt=
ion)
with CRYPTOPP_BOOL_ALIGN16=3D0, leading to the missing function.
Not sure how to approach this. Maybe write the chosen `CRYPTOPP_DISABLE_*` =
into
the installed `config.h`?!
