Hi,
I've been trying to get cryptopp-5.6.0 up and running with Sun Studio on
Solaris/OpenSolaris for a while now. Sun Studio 12u1 is listed as a new
compiler (Sun CC 5.10).
Now there are several problems:
- First of all I needed to remove some superfluous static keywords in
eccrypto.cpp to fix a scope visibility limitation. This is patch 1.
- After that I fixes some settings in the GNUmakefile to make it build
(i.e. link with all templates) reliably . This is patch 2.
- Patch 3 concerns non-aligned accesses. This fix is incomplete, because
I didn't know how to resolve the issue with ByteReverse in misc.h.
Therefore, I added -xmemalign=8i to force reinterpretation of
non-aligned memory accesses to prevent bus-errors.
- Then after buiding the 64bit version the validation will bail out with
an error message during DH testing concerning the stream being not
seekable. I didn't dig into it so I have no clue what the problem might be.
- Reverting back to 32 bit mode on SPARC, the validation crashes during
RSA testing. I've been looking into this for a while and I've been
trying different compiler versions of the sun compiler, all with the
same effect. I think the underlying problem is somewhere in the
construction of SecBlock objects in secblock.h. The stack trace is below
(2). The same problem exists also in 64bit mode.
Anybody got any ideas concerning these issues? I'd really like to get
RSA running, as Solaris+Sun compilers is my main development platform,
because of tool support...
Would it be possible to integrate at least patches 1 and 2 in the
upstream? That would be great.
Cheers,
Thomas
