[Bug]: undefined reference to `__aeabi_read_tp' about wolfssl

[1756816846]

I used -- disable benchmark to compile Wolfssl successfully, but now there is an error in compiling the demo

Hi @1756816846 ,

It looks like you are linking wolfSSL to your application and seeing build errors there. You need to include our options.h and settings.h headers before all other wolf/OpenSSL headers in all files which include these headers:

#include <wolfssl/options.h>
#include <wolfssl/wolfcrypt/settings.h>

I would also recommend removing WC_NO_HARDEN as this define should not be needed.

#include <wolfssl/options.h>
#include <wolfssl/wolfcrypt/settings.h>
#include <wolfssl/ssl.h>

Hi @1756816846 ,

The SHA2-512 requires a 64-bit type. Most 32-bit systems support a "long long" or "uint64_t". I suspect your compiler and configure is not properly detecting "long long" as 64-bit.

You can try adding CFLAGS="-DSIZEOF_LONG_LONG=8" to the ./configure.

If that doesn't work please share your config.log from ./configure.

Thanks,
David Garske, wolfSSL
