Bug reference: 16773
Logged by: George Tarasov
Email address: jatoba@gaz-is.ru
PostgreSQL version: 12.0
Operating system: Windows MSYS2/MINGW64
Description:
Dear hackers,
I am being engaged in PostgreSQL build process with GSSAPI support in
msys2/mingw64 environment.
Everything is good enough on REL_11_STABLE branch, but there are the
following compilation and linking errors on newer versions/branches
(12-stable, 13-stable, and 14-devel).
Errors connect with setenv() call that isn't supported in msys2/mingw64.
be-secure-gssapi.c: In function 'secure_open_gssapi':
be-secure-gssapi.c:493:3: warning: implicit declaration of function
'setenv'; did you mean 'getenv'? [-Wimplicit-function-declaration]
setenv("KRB5_KTNAME", pg_krb_server_keyfile, 1);
^~~~~~
getenv
libpq/be-secure-gssapi.o: In function `secure_open_gssapi':
D:\postgresql\src\backend\libpq/be-secure-gssapi.c:493: undefined reference
to `setenv'
collect2.exe: error: ld returned 1 exit status
I have read this [1], this [2], and this [3] and as i understood it's
recommended to use more convenient putenv() insted of setenv().
But the function setenv() is still there and the patch proposed in [3] have
not yet been approved.
Please comment
Is there a plan to clean code from setenv() call and will the proposed patch
[3] or its revised versions be applied ??
Or setenv() is our Happy Future and PG-code will stay broken for non-common
execution environments, namely those, that use, for example, GSSAPI support
in msys2/mingw64.
Also I have checked BuildFarm statuses and all mingw64-nodes build PG
without GSSAPI/KRB5 support [4].
It looks like the mingw64 platform is no longer being considered as LTS and
will be in reduced feature list in the future.
Am i right?
Thanks!
