Compilation fails on Debian/Sid

Hello, probably Debian/unstable isn't supported but if someone could be so kind to give an help I'd be really happy and that would be very likely useful for the next stable release too.
The error is:

Any idea?

Ha, I didn't notice there was a post on this already and submitted another one (pending approval -- mike: feel free to drop it).
ECDSA_SIG became an opaque structure not allocatable on the stack some time ago[1]. I think it was never meant to be, in fact BIGNUM was made opaque longer ago[2] and I think the libabi code only works because it copies pointers to existing structures, since BIGNUMs have dynamically allocated members that one can't just hope they materialize...
In the meantime, you can restore the definition of ECDSA_SIG_st in the libabi/src/ossl_ec.c file using that structure (note that the position of the definition is important). It's a hack, not a solution in any way.

Nice work. I cannot tell if it's just an hack or workaround, but it solves my compilation problems and makemkv starts. Many many thanks.

I too have had this problem. I'm running VectorLinux (essentially Slackware 14.1 x64). I wonder if I have applied this fix correctly:
Code: Select all
#include <lgpl/osslabi.h>
#include <openssl/opensslconf.h>
#include <openssl/bn.h>
#include <openssl/crypto.h>
#include <openssl/opensslv.h>
struct ECDSA_SIG_st {
BIGNUM *r;
BIGNUM *s;
};
#if defined(OPENSSL_FIPS) && defined(OPENSSL_HAVE_INIT)
#define UGLY_FEDORA // always disables EC with key size < 256 bits
#endif
However, I get the following error:
-Xlinker -soname=libmakemkv.so.1 -lc -lstdc++ -lcrypto -lz -lexpat -lavcodec -lavutil -lm -lrt
In file included from libabi/src/ossl_ec.c:40:0:
/usr/include/openssl/ecdsa.h:78:16: error: redefinition of 'struct ECDSA_SIG_st'
libabi/src/ossl_ec.c:27:8: note: originally defined here
make: *** [out/libmakemkv.so.1.full] Error 1
I have also tried with commenting out the #include <openssl/ecdsa.h> line below, but it seems that this is needed elsewhere. Any thoughts? Am I doing something boneheaded, or not implementing your fix correctly?
Thanks!

You shouldn't need the patch with 1.10.4.

Interestingly, when I went back to 1.10.3, I didn't need the patch (and it compiled without complaint!), but on 1.10.4, I can't seem to get it to compile no matter what. I've got to wonder if it isn't because we're still using OpenSSL 1.0.1 on VectorLinux 64bit (7.1). In any event, thanks for the reply.

Ah, yes. If this is the error you get, you don't need the patch I suggested earlier:
Code: Select all
/usr/include/openssl/ecdsa.h:78:16: error: redefinition of 'struct ECDSA_SIG_st'
Not sure what error you get with 1.10.4, perhaps post that?
