It is possible to disable the mlock thingy and if that is not wanted the application should be modified to be suid(root) during Libgcrypt initialization - this is actually how we handle this in GnuPG. Or maybe I don't understand the bug described here. It seems to be more of a support question.

No, c99 was never required. Meanwhile we use a few c99 features but those are supported without any compiler option.

-std=c99 is probably the reason that the tests fail.

Please try with out supplied CFLAGS or change them from

@sarman: Your question is actually a support question and not a bug report. Please read the documentation, use the public help channels (so that other can also learn from the issue), or get in touch with a commercial support provider.

I think that what you want is adding --batch option. In the gpg manual, we have:

--passphrase-file file
       Read  the passphrase from file file. Only the first line will be
       read from  file  file.  This  can  only  be  used  if  only  one
       passphrase is supplied. Obviously, a passphrase stored in a file
       is of questionable security if other users can read  this  file.
       Don't use this option if you can avoid it.

Hello Team,

For operations which require private key, it is needed to unlock private key.

Regarding Cygwin: The sources are a bit hard to find.
https://cygwin.com/packages.html
-> https://cygwin.com/packaging/repos.html
-> https://cygwin.com/git-cygwin-packages/
-> https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/libgcrypt.git;a=summary

Regarding GNU/kFreeBSD, my machine is using the FreeBSD 9.0 kernel, which does not yet have the security.bsd.unprivileged_mlock oid. Like what was mentioned here: https://lists.debian.org/debian-bsd/2014/08/msg00092.html

For Cygwin, I can't find how its libgcrypt package is built.
I found this for MSYS2: https://github.com/msys2/MSYS2-packages/tree/master/libgcrypt
This for Mingw-w64: https://github.com/msys2/MINGW-packages/tree/master/mingw-w64-libgcrypt

I tested on FreeBSD. Same errors (t-secmen and t-sexp) are reproducible when we set:

On Solaris, the test errors are because of:

USAGE
       Because of the impact on system resources, the use of mlock() and
       munlock() is restricted to users with the {PRIV_PROC_LOCK_MEMORY}
       privilege.

OK, I identified the problem on OpenIndiana. The inclusion of <unistd.h> causes inclusion of <sys/types.h> before config.h. I'm going to fix this.

For GNU/Linux or GNU/kFreeBSD system, libgcrypt 1.8 with libgpg-error 1.36 has no problem in Debian build:
https://buildd.debian.org/status/package.php?p=libgcrypt20

In solaris11openindiana-log2, we have two errors: one for ulong, and another for ushort.
I fixed the former. It is because of our mistake of using ulong before it is handled by libgcrypt/src/types.h. In the first place, it is implemented by "unsigned long", so, there is no need to use ulong here.

I applied https://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=patch;h=8d1b5982138c104f3c50663738892fa110193059 on top of 2.2.14.

We fixed that in master and 2.2. Can you please test this with the next release and report or close this bug?

Thanks for the report. underscore followed by an uppercase letter is actually reserved for the system; thus we should not have used that.

It is in 1.30 which I released a few minutes ago. Only minor other changes.

Argh. I missed that. Probably because I searched for libgpg-error but I myself renamed the tag recently :-(.

Put the check in configure.
