Similar issue with ntbtls:

FWIW:
The first config.log is from a gnutls build.
The second for libassuan 2.5.3 and has been configured:

./configure --enable-shared --prefix=/var/tmp --libdir=/var/tmp/lib64

Okay, I see the problem. The microsoft toolchain is more picky about de-facto standard use patterns with common blocks and the author of that code was not ware of this. Thanks for reporting, will be fixed in the next release.

This is not about a function, but about the variable _gpgrt_functions_w32_pollable. And this is not about exporting the variable from the library, but about declaring it as extern in gpgrt-int.h, so that gpgrt-int.h can be included in multiple translation units without defining the variable in each.

This function is not exported on purposes. Even the name of the header file indicates that tis is internal. External, that is public functions of the API, are defined gpgrt.h and only made externally visible by including them in the .def file. This has not been done and so I don't understand your bug report.

Applied.

News for 1.34:

Topic branch of libgpg-error is not good to show changes (for other libraries).
So, I made D473: Introducing LDADD_FOR_TESTS_KLUDGE to enable 'make check' with LD_LIBRARY_PATH.
Appliying to libgpg-error.

For other distros, it seems it's quite old issue: https://sourceware.org/ml/binutils/2012-05/msg00037.html

My patches on the topic branch: https://dev.gnupg.org/source/libgpg-error/history/gniibe%252Fdisable-new-dtags/

My tentative conclusion: When (GNU) ld supports --disable-new-dtags, add it to LDADD in tests/Makefile.am.

Reading this discussion: http://lists.gnu.org/archive/html/bug-libtool/2018-01/msg00014.html
It seems that it could be fixed if we care about the order of libraries.
And it's not the issue for libgpg-error, which doesn't require external libraries.

For binutils, in Stretch, Debian specific patch was introduced.
Then, upstream introduced --enable-new-dtags option for configure to build binutils.
Now, Debian uses --enable-new-dtags option (at build time).

NEWS for 1.33:

I don't think this works for me in that way.

Use that function as early as possible. The gpg-error tool has also be enahnced on Windows:

Thanks. In the meantime GpgOL takes it's language from the Outlook configured display language setting. I'll add support for override locale to gpgol so that the locale is set accordingly

So far, so good.

To avoid the drawback, we can put the logic of locating possible libdir in gpg-error.m4, instead of putting in the script.

It builds for me now. I had a mismatch with a to old gpgrt-config and did not properly set PKG_CONFIG_PATH

libassuan master fails to compile for windows against libgpg-error master http://paste.debian.net/1049534/ I think gpg-error.m4 ignores both sysroot and --with-gpg-error-prefix

We need more testing.

I decided to change gpgrt-config to have --libdir option.
By supplying libdir directly, it's no need anymore to detect the directory by CC variable.
gpg-error.m4 is also updated.
