[openssl-users] Problem compiling EVP_aes_128_gcm()

[Lior Koskas]

 I viewed the file and the definition exists.
I also checked that I'm picking the correct version.

My problem is this line : EVP_EncryptInit_ex(&_ctx, EVP_aes_128_gcm(),
NULL, NULL, NULL);

I also tried to change the code to this two lines :
EVP_CIPHER *EVP evp_gcm = EVP_aes_128_gcm();
EVP_EncryptInit_ex(&_ctx, evp_gcm, NULL, NULL, NULL);

After the change I got this error : expected initializer before ‘evp_gcm’

What am I doing wrong?
