Linux & Openssl, Invalid arguments ' Candidates are: int BN_set_word(bignum_st *, ?) '

[Giuseppe Barbieri]

I am using OpenSSL for a cuda project.

I just imported all the project from win to linux (Eclipse)

I solved all the dependencies except this annoying error:

> Invalid arguments ' Candidates are: int BN_set_word(bignum_st *, ?) '


for this line:

    BN_set_word(two, 2);

and the function itself says in the bn.h

    int    BN_set_word(BIGNUM *a, BN_ULONG w);

Where BN_ULONG is defined as:

    #define BN_ULONG    unsigned long

Neither it works if I do something like

    unsigned long q = 2;
    BN_set_word(two, q);

Because it returns

> Invalid arguments '
Candidates are:
int BN_set_word(bignum_st *, ?)
'

or

    BN_ULONG q = 2;
    BN_set_word(two, q);

that gives

>Type 'BN_ULONG' could not be resolved

What is the problem?


Thanks in advance,
Giuseppe
