Hello,
I was indeed not including the options.h and just set the flags I need myself. I deleted all of them and included the wolfssl/options.h instead but it did not make a difference.
I am working on Debian Linux:
$ uname -a
Linux dev 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1+deb8u2 (2017-03-07) x86_64 GNU/Linux
and I configured with the following flags:
./configure --enable-aesgcm --enable-aesccm --enable-mcapi --enable-fastmath --enable-sha512 --enable-ecc --with-libz
with generated the options.h attached to this post. It should be noted that I also wrote code for running AES with different modes of operation using fastmath without problems. In the future, this code is supposed to run on a board and I did cross compile the AES-tests with fastmath for it without problems, too.
After configuration I run make clean, make, sudo make install..
When I encountered this error in my code I tried to run a more simple example code taken but adjusted from the test.c.
#include <wolfssl/wolfcrypt/aes.h>
#include <wolfssl/wolfcrypt/dh.h>
#include <wolfssl/options.h>
void
simple_test()
{
size_t testVal = 23;
WC_RNG rng;
int ret;
ret = wc_InitRng(&rng);
DhKey smallKey;
byte p[2] = { 0, 5 };
byte g[2] = { 0, 2 };
byte priv[2];
word32 privSz = sizeof(priv);
byte pub[2];
word32 pubSz = sizeof(pub);
printf("testval is %zi\n", testVal);
wc_InitDhKey(&smallKey);
printf("testval is %zi\n", testVal);
ret = wc_DhSetKey(&smallKey, p, sizeof(p), g, sizeof(g));
if (ret != 0)
printf("Error");
ret = wc_DhGenerateKeyPair(&smallKey, &rng, priv, &privSz, pub, &pubSz);
wc_FreeDhKey(&smallKey);
if (ret != 0)
printf("Error");
wc_FreeRng(&rng);
wc_FreeDhKey(&smallKey);
}
int main(int argc, char** argv)
{
simple_test();
return 0;
}
I am using netbeans with its default generated Makefile. The compilation process looks like this
g++ -lwolfssl -c -g -std=c++11 -MMD -MP -MF "build/Debug/GNU-Linux/main.o.d" -o build/Debug/GNU-Linux/main.o main.cpp
g++ -lwolfssl -o dist/Debug/GNU-Linux/wolfssl_test build/Debug/GNU-Linux/main.o
And the output like this:
testval is 23
testval is 0
RUN FINISHED; Segmentation fault; real time: 10ms; user: 0ms; system: 0ms
I might have found something: Netbeans showed that there are 'unresolved includes' in wolfssl/wolfcrypt/dh.h leading to integer.h and to mpi_class.h, but I don't know what to do about it.
Hope that helps,
telina

. Thank you very much! I am trying to get the code to run on the board now.
