Missing header file ts_local.h in install location.

Fri Jun 28 16:15:17 UTC 2024

Hi Matt,
Yeah,  that’s what I thought too, but they claim they built it with openssl 3.0.8 in their INSTALL file.
https://github.com/DCMTK/dcmtk/blob/59f75a8b50e50ae1bb1ff12098040c6327500740/INSTALL#L219
I have also posted on their discussion board.

Thanks.

It looks to me like DCMTK needs updating to use OpenSSL 3.x

This particular error occurs because line 1342 of sitstamp.cc looks like

this:

     TS_VERIFY_CTS_set_certs(ctx, NULL);

Earlier on in that file we see this:

#ifndef HAVE_OPENSSL_PROTOTYPE_TS_VERIFY_CTS_SET_CERTS

#define TS_VERIFY_CTS_set_certs(x,y) ((x)->certs = (y))

#endif

So if HAVE_OPENSSL_PROTOTYPE_TS_VERIFY_CTS_SET_CERTS isn't defined then

it will attempt to look inside the TS_VERIFY_CTX structure - which is

not allowed from 1.1.1 onwards because it is opaque.

My guess is the setting of

HAVE_OPENSSL_PROTOTYPE_TS_VERIFY_CTS_SET_CERTS is going wrong with

OpenSSL 3.X

It seems to get defined by Cmake/dcmtkPrepare.cmake:

   CHECK_FUNCTIONWITHHEADER_EXISTS("TS_VERIFY_CTS_set_certs(0,0)"

"openssl/ts.h" HAVE_OPENSSL_PROTOTYPE_TS_VERIFY_CTS_SET_CERTS)

Indeed that function header does *not* exist in 3.x because it is

instead a macro:

# ifndef OPENSSL_NO_DEPRECATED_3_0

#  define TS_VERIFY_CTS_set_certs(ctx, cert)

TS_VERIFY_CTX_set_certs(ctx,cert)

# endif

In 1.1.1 this was a full C function so the cmake detection would have

worked correctly there.
