Suggestions for gpgme on mingw-w64

[Andre Heinecke]

Hi,

Sorry to pull out such an old thread but I just ran into the same problem
as I was trying to use GpgME statically linked into GpgOL.

After wasting some time figuring out why every call returned
"Unsupported Protocol" I figured out that this here was also my problem.

Works great! Useful :-)
Although I wondered a bit if we shouldn't try the same fallbacks that 
we use to find gpgconf to find gpgme-w32spawn.exe, too.
This would also solve this problem I guess.

The extra diagnostic was a bit useless for me. First I had to start Outlook
in an environment with GpgME debugging and then
as spawnhelper was NULL it would print:

GPGME 2016-08-18 15:55:41 <0x13b0>    gpgme-dinfo: gpgconf='C:\Gpg4win\..\GnuPG\bin\gpgconf.exe'
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_pipe: enter: filedes=02A5E3AC, inherit_idx=1 (GPGME uses it for reading)
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_pipe: leave: read=0x0 (000025B0/0x0), write=0x1 (00002B3C/0x0)
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_spawn: enter: path=0B34B048, path=C:\Gpg4win\..\GnuPG\bin\gpgconf.exe
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_spawn: check: path=0B34B048, argv[ 0] = C:\Gpg4win\..\GnuPG\bin\gpgconf.exe
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_spawn: check: path=0B34B048, argv[ 1] = --list-dirs
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_spawn: check: path=0B34B048, tmp_name = C:\Users\AHEINE~1\AppData\Local\Temp\gpgme-zPTgnT
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_spawn: check: path=0B34B048, CreateProcess failed: ec=87
GPGME 2016-08-18 15:55:41 <0x13b0>      _gpgme_io_spawn: check: path=0B34B048, (is '(null)' correctly installed?)

No mention of gpgme-w32spawn.exe and all paths looked completely
correct for my system. Very little difference in the output to the working
case :-/

So instead I've now (9cf983b0) added a big fat MessageBox in that case:
https://files.intevation.de/users/aheinecke/gpgme_spawn_not_found.png

because I also don't find it intuitive that a library needs a binary to work
and usually if I package a library I just package the library and omit
any binaries that this library installs.


Regards,
Andre
