Hi!  Try again using GnuTLS 2.6.6.  The DSA keys generated with GnuTLS
2.6.x with x < 6 were corrupt, and cause the error you encountered.
Thanks for reporting your problems.

Install Problems

Hi all,

I tried to install GnuTLS, which results in errors when executing make 
check.

libgpg-error 1.7 has been installed with

./configure; make; make install (make check completes successfully)

libgcrypt 1.4.4 has been installed with

./configure --prefix=/usr --with-gpg-error-prefix=/usr/local; make; make 
install (make check completes successfully)

gnutls 2.6.6 has been installed with

./configure --prefix=/usr --disable-srp-authentication   
--disable-openpgp-authentication
make
make install

make check says "11 of 23 tests failed"

most of the errors sound like

server: ready. Listening to port '5556'.
Launched, generating DH parameters...
server: connection from 127.0.0.1, port 58289
./resume: relocation error: 
/usr/local/src/gnutls-2.6.6/lib/.libs/libgnutls.so.26: symbol

Try adding --with-libgcrypt-prefix=/usr/local.  Otherwise it likely
tries to use libgcrypt from /usr.

Yes, it seems to use one libgcrypt during linking and another one when
running.

Stupid... yes, you were right. I installed libgcrypt to /usr/lib, but 
that was not in ld.so.conf (I thought only /usr/local/lib is missing 
from time to time, not /usr/lib *sigh*)

Thx!

Re: Libtasn1 2.1

Simon,

I also found that libtasn1.pc also licensed under GPLv3. It this true?

A library of LGPL v2 lives with a .pc file with GPL v3?

It doesn't exist on Windows, I think.  Try setting it to long and see if
it works.

Btw, rather than building it on Windows natively, you may try to use a
GnuTLS DLL built using mingw instead: http://josefsson.org/gnutls4win/
It includes DLLs for libgcrypt and libgpg-error as well.

Hi.  I've re-licensed it to LGPLv2.1+, see:

http://git.savannah.gnu.org/cgit/libtasn1.git/commit/?id=009b6c20ffc0164189691b47ad5f172518b97169

Re: Libtasn1 2.1

Thanks for your quick response.

Do you think that Makefile.am under lib also needs to be licensed to
LGPL?

I don't think so, since it is not something that is include in the
installed software.  The GPLv3 Makefile.am is needed to build libtasn1,
but so is other GPLv3 tools (e.g., bison) so I don't see the difference.
