gettext: can no longer work with nul files

[lazka]

$ echo -e "msgid \"a\"\nmsgstr \"a\"" > a.po
$ msgfmt.exe a.po -o nul -v
C:\msys64\mingw64\bin\msgfmt.exe: error while opening "nul" for writing: Invalid argument
1 translated message.

shouldnt that be /dev/nul ?

[1480c1]

I'm assuming since this is for mingw-w64, it would try to open window's nul file

[revelator]

not sure we can access the windows nul from bash easily ?

[1480c1]

From bash and anything linking to cygwin, nul is just a normal file that it can create, write to, delete, etc, it has no special handling of nul, meaning I can create a file called nul and edit it in nano, but not be able to delete it from powershell etc.

[revelator]

well it should actually work, tested it this way ->

Revelator@DESKTOP-BPM81CH MINGW32 ~
$ echo test >nul

Revelator@DESKTOP-BPM81CH MINGW32 ~
$ cat nul
test

[lazka]

I'm seeing the issue without any cygwin involved. I just used bash here for an easy reproducer.

[revelator]

well that is odd then :/

Just hit this as well when building darktable:

the problem is in gnulib, fopen_supersede() withsupersede_if_does_not_exist=true fails

Yes, that fixes things. Needs to be backported.

Fix is in the repo
