As alternative I suggest to use instead of the string built using
all the language names, its md5sum, like in this small shell script:

#!/bin/sh
LONG_FILENAME="en-US_af_ar_bn_be-BY_bg_ca_cs_cy_da_de_el_en-GB_eo_es_et_eu_fi_fr
_ga_gl_gu-IN_he_hi-IN_hr_hu_it_ja_km_kn-IN_ko_lo_lt_ms_ne_nb_nl_nn_nr_ns_pa-IN_p
l_pt_pt-BR_ru_rw_sk_sl_sh-YU_sr-CS_ss_st_sv_sw-TZ_ta-IN_th_tn_tr_ts_ve_vi_xh_zh-
CN_zh-TW_zu"
SHORTER_FILENAME=`echo $LONG_FILENAME | md5sum |cut -f1 -d" "`
echo $SHORTER_FILENAME

which gives:

1bacc6d05a040cae0afe7acacd279fc1

So we'll have:

.../src680-m128/instsetoo_native/util/OpenOffice/install/1bacc6d05a040cae0afe7acacd279fc1_download_inprogress
.../src680-m128/instsetoo_native/util/OpenOffice/logging/1bacc6d05a040cae0afe7acacd279fc1/log_SRC680__1bacc6d05a040cae0afe7acacd279fc1.log

in this way the filename lenght will be of only 32 characters long
(or 52 with the appende string _download_inprogress), but will be
always the same, according to any number of language built, and the
dependency on the language names will be also preserved.

WDYT?

of @ mh: Please have a look.

I suggest to do a replace like "all_lang".

If you replace the string to "all_lang", it would work only when "all languages"
are choosen, but one might chose a set of languages to
build which is near to all languages (e.g. all languages
but one), and would cause the string to be bigger than 255 chars anyway.

- I'm not the author of this code

- this is not the default setup (configurations)

ghibo: how did you started the build for all languages? Why do you want to have
one instset with that many languages in it?

1) yes, with argument of config_office/configure's --with-lang=ALL or
--with-lang='ar be...'.

2) Why there shouldn't be built all the languages (or most of) if they are
included in the source? And anyway this is needed for multiple language
package building.

3) It seems the problem is in the file solenv/bin/make_installer.pl, probably
in the building of var $loggingdir as well as $languagestringref. Who wrote
that code?

Well, I wrote the code. And I introduced this directory names, because they show
the content of the directories and the log files. Nobody knows, what he can find
in a directory or a file named "1bacc6d05a040cae0afe7acacd279fc1"
If you build different installation sets with different languages this will not
be a good solultion.
Normally our installation sets do not have so many languages. I think this
installation set will have a size of more than 1 GB.

I too think such big instset is a special case. What about something like this
(meta-code):

NAME="en-US_pt_..."

if ( length($NAME) >150 )
    NAME=md5sum($NAME)

It is simple and the special case is solved too?

x is: yes, more or less you get 30MB (unpacked) more for each language (the main
one for 1 language is around 360MB unpacked). Consider that later you split the
whole installation into subpackages (one big for main [libraries+en_US], plus
small subpackages of 10-12MB in size, one for each language to be added to
the main one).
Regarding your consideration about the naming, yes, the md5sum may appear
ugly, but on the other hand the translation string is contained into the build
set. Maybe you may the script a little more verbose printing on stdout both
the string of languages and its md5sum so that would be more easy to find.
Or even better you put a filename in the same place, called for instance
"1bacc6d05a040cae0afe7acacd279fc1.dir" (.dir for dirs, and .file for files)
which will contain the string of languages, maybe even in a more readable
(and sorted) way:

en_US
af
ar
bn
be-BY
bg
ca
cs
cy
da

instead of "en-US_af_ar_bn_be-BY_bg_ca_cs_cy_da_de_el_en-GB_..."

The pjanik suggestion sound good, i.e. only
use the md5sum replacement when the filename goes beyond a certain
amount. 100-150 chars can be a good value too.
