d.fontlist crashes on Windows

[annakrat]

When changing default font for display commands in GUI settings, the underlying command d.fontlist crashes. This is what I get when running d.fontlist from terminal (with d.mon wx0):

D1/5: G_set_program_name(): d.fontlist
D2/5: G_file_name(): path = C:\Users\akratoc\grassdata/nc_spm_08_grass7/user1

Happens with cairo and png driver. tested on several computers with Windows 8 and 10. This works in 7.0.2.

Could it be related to any changes done for #2448?

I can't see this connex, as it also fails in OSGeo4W-g7 (see above); changes done for #2448 doesn't do anything in OSGeo4W-g7.

Fontconfig error: Cannot load default config file

any idea in the code where this default config file is searched

trying here:

g.mkfontcap -s

gothitt|Gothic Italian triplex|0|C:\OSGEO4~1\apps\grass\grass-7.0.3RC1\fonts\gothitt.hmp|0|utf-8|
[...]

so correctly updated fontcap file is found here by g.mkfontcap.

the question is if the fontcap file is the same as the default config file?

tested with font types listes by g.mkfontcap -s, all vector labels are displayed correctly; e.g.:

d.vect map=firestations@PERMANENT width=1 attribute_column=CITY font=georgiab
d.vect map=firestations@PERMANENT width=1 attribute_column=CITY font=FRADMCN

[martinl]

The programs crashes at source:grass/trunk/lib/driver/font.c#L151​

Any idea?

[martinl]

Hopefully fixed in r67630. Will check next build.

tested here locally by copying

C:\OSGeo4W\etc\fonts\fonts.conf

to

C:\OSGeo4W64\apps\grass\grass-7.0.3RC1\etc

and by adding

set FONTCONFIG_FILE=%GISBASE%\etc\fonts.conf

in the winGRASS windows console.

good, done in r67642. Let's test the next grass70 build.

[annakrat]

Thanks for working on this. Do we have an idea how did this bug happen? If yes, it would be good to have it documented here.

[martinl]

GRASS OSGeo4W package since 7.0.3 doesn't depend on msys package. WinGRASS is built using completely fresh environment based on msys2 which is not shipped in osgeo4w framework. So the fontconfing file was just missing.
