[Debian-med-packaging] Bug#775302: [fis-gtm] UTF-8 libgtmutils.so in fis-gtm-6.2-000 is missing routines

[Amul Shah]

Hi Andreas,
Good news, I have a fix! But I think there may be a more appropriate fix. Please read below.

I finally got around to using cowbuilder to setup a clean build environment for myself. I'm not sure what the hold-up was 
earlier, it's not hard.

Let me first describe the source of the bug. The script sr_unix/configure.gtc is responsible for doing the final installation of 
GT.M. Among other things, it compiles M routines into object code for both M mode and UTF-8 mode. The section that built the 
UTF-8 mode object files did the following to extract a UTF-8 locale for the GT.M compiler to use.
     697 # Now work on UTF-8 mode
     698 if [ "$doutf8" -ne 0 ]; then
     699         # Enclose UTF-8 operations inside a subshell. This avoids changing the current M mode execution
     700         (
     701                 # Ensure we ARE in UTF-8 mode
     702                 utflocale=`locale -a | grep -i en_us | grep -i utf | grep '8$' | head -n 1`
     ...
     712                         LC_CTYPE=$utflocale
     713                         export LC_CTYPE
     ...
     730                 (gtm_dist=$gtmdist/utf8; export gtm_dist; cd $gtm_dist; ./mumps -noignore *.m; $echo 
$?>>$gtmdist/compstat; \
     731                 if [ $is64bit_gtm -eq 1 -o "linux" != $arch ] ; then $ldcmd $ldflags -o libgtmutil$ext *.o ; fi )

Line 702 doesn't work correctly because 'locale -a' lists the following locales:
     C
     C.UTF-8
     POSIX

Removing the 'grep -i en_us' from line 702 above allows the script to match the locale 'C.UTF-8' and generate the UTF-8 mode 
object files on line 730.


While this fix works, it strikes me as not completely correct because debian/rules sets up a locale for the pbuilder environment 
(lines 21-27 copied in below). What do I need to do in order to use locale from override_dh_auto_build in override_dh_auto_install?
      21 # Set up locale support in the pbuilder environment
      22 override_dh_auto_build:
      23         mkdir -p debian/tmp/locale/
      24         localedef -f UTF-8 -i en_US ./debian/tmp/locale/en_US.UTF-8/
      25         export LOCPATH=$(CURDIR)/debian/tmp/locale/ && \
      26         export LC_ALL=en_US.UTF-8 && \
      27         dh_auto_build

thanks,
Amul
