Hi Edwin,
The attached test does something very similar to GNUstep, and you should get the same answers. Can you check this out and report back?

To build:
cc test_icu.c `icu-config --ldflags --ldflags-icuio`

My results:
Date Formatted with defaults: 20170914 12:26 p.m.
Date Formatted with defaults: 14 sep. 2017
Date Formatted with defaults: 14 september 2017 12:26:33 GMT-4

Regards

I'll come up with a test for ICU and post it here. I'll make sure to use the same functions used by GNUstep to verify.

I'm still betting the problem is in your ICU installation. The GNUstep code is a thin layer on top of ICU, it's unlikely that the problem lies there. I'm not saying impossible, just unlikely.

Stefan,

I did, and the test returns the same wrong results:

Could i run a C-program that formatted the date with locale nl and conclude
- the problem is in my ICU installation if the result of the program is wrong?
- the problem is in my GNUstep installation if the result of the program is OK?

Kind regards

Hi Edwin,
From everything you've said so far, the problem doesn't seem to be in GNUstep. The method you are using would return nil if ICU wasn't installed. Additionally, the return value is what you'd expect from the en_US_POSIX locale, the default in FreeBSD.

With that in mind, have you tried explicitly setting the formatter's locale using the -setLocale: method? It's possible your setup is falling back to the systemLocale, which would be a separate problem.

Have you tried running the test I attached in my previous email?

Regards

Hello,

I return from holidays that have been haunted by this problem :-).

I asked about libicudata.so on the freebsd list. The answer was " devel/icu is built --with-data-packaging=archive which means the data ends up in icudt* file e.g.,

$ pkg info -l icu | fgrep icudt | xargs du -Ah
25M /usr/local/share/icu/58.2/icudt58l.dat"

We compared the necessary ICU libraries and they all are present at my side, with more or less equal sizes.

In the config.log file for gnustep base, I found:
...
HAVE_GNUTLS='1'
HAVE_ICU='1'
HAVE_INET_NTOP='yes'
HAVE_INET_PTON='yes'
HAVE_LIBDISPATCH='1'
HAVE_LIBXML='1'
HAVE_LIBXSLT='1'
HAVE_MDNS='0'
HAVE_OBJC_SYNC_ENTER='yes'
...

This seems to indicate ICU is used. Just to be sure, I added

#if GS_USE_ICU == 1
      NSLog(@" GS USE ICU == 1");
#endif

to my program, and effectively, the display appeared:

2017-09-14 11:04:41.625 TM1[79500:100088] GS USE ICU == 1

I tried debugging, but from a recent conversation on this list, it seems I need a port gdb80, that is not present in my FreeBSD 11.0 ports directory (have got gdb and gdb66).

I must be missing something obvious, but for now, I'm rather stuck. Problems like this make one feel utterly stupid.

Would you have any suggestions left?

(I already reinstalled the icu and gnustep base ports, no errors detected, no change in the result).

Kind regards,

Edwin.
