Subject: RE: [gnutls-devel] Missing function. Where is version_to_entry defined?
OK, so I looked into this.
While building libgnutls.so.28.41.3 I see that libtool is building a .exp file to be fed to cc -M {file}.exp.
This is defining which symbols to be global vs local. I would expect this mapping to only apply to .o files being included in the archive, but it's changing functions in the .a files like libgnutls_alg.a that are GLOB to LOCL
With -M
$ nm .libs/libgnutls.so.28.41.3 | grep version_to
[296] | 1068728| 128|FUNC |LOCL |2 |10 |version_to_entry
Without -M
$ nm .libs/libgnutls.so.28.41.3.save | grep version_to
[15274] | 1822032| 128|FUNC |GLOB |0 |9 |version_to_entry
While removing the -M from the compile line fixes this issue, I am not sure what other issues it may generate.
The same method was used for libgnutls.a and it seems to have worked:
$ nm .libs/libgnutls.a | grep version_to | grep -v UNDEF
[97] | 6448| 128|FUNC |GLOB |0 |2 |version_to_entry
Why not just convert the .a to a .so directly instead of rebuilding it from scratch...which didn't work.
Here is the "cc" line that builds on Solaris10 with solarisstudio12. (I formatted it for readability) and tested both with and without the -M.
Just removing the -M fixed the linking problems. All the tests that ran passed. SRP tests then ran into an undefined symbol. See the bottom of this message.

On Solaris, AF_UNIX is defined and the CODE should be checking for this. Some parts of gnutls ARE checking:
from lib/nettle/egd.c
#ifdef AF_UNIX
#define LOCAL_SOCKET_TYPE AF_UNIX
#else
#define LOCAL_SOCKET_TYPE AF_LOCAL
#endif
I changed tests/srp/mini-srp.c tests/dtls/dtls-stress.c to use the same setup as in egd.c. Can THIS at least be fixed in the code base?
Also there are a lot of these warnings around...in the entire package...
"/appl/gfpip/local_build/src/gnutls/gnutls-3.3.11/tests/srp/mini-srp.c", line 208: warning: implicit function declaration: kill
This is resulting from a missing "#include <signal.h>" in many files.

You shouldn't need to add libgnutls_alg.la there. libgnutls_alg.la is
part of libgnutls.la. You may be hitting a libtool bug for the
platform you are.
