Are you sure you are executing the script with `bash' and not `sh' ? The first line would seem to suggest `sh' which may be the cause of the problem. Nick.

hi frank i'm not a bash expert either: it took me 2 hours to come up with the following enter the following 6 lines of code in a file called test #!/bin/sh if [ $1 = $2 ]; then echo "ok" else echo "oops" fi next, chmod 777 test then try it: ./test 1 1 and ./test 1 2 now go back and change the = to == and try it and you get ./test: [: ==: binary operator expected oops note: bash is from slakware 3.5 thanks russ

(`Trim' is a predefined function of the standard, so we have to care about the standard here.) Technically, of course, it would be easy to do it. Alternatively (if the standard wants only spaces), we could also make a different routine for spaces and tabs...

First of all, I'm not so much of a bash expert. What do you mean by "bash defaults to always false when it sees =="? My man page says `==' may be used in place of `=' in comparisons, and I can't seem to find any difference in bash's behaviour. Does it mean that (some version of ?) bash does not recognize `==' as a comparison operator? Secondly, I'm a bit surprised about the symptom. The only `==' I could find were one in Make-lang.in in the main GPC source directory, and two in Makefile.in in the rts subdirectory. All of them were of the form "if [ x$(WITH_SHARED) == xyes ] ; then ...", to test whether one wants to build a shared library of the RTS. I can't see any connection to not linking ncurses. -- Well, perhaps, due to the make failing here, it did not get to the point of installing the new units, so GPC used the units of an older version which did not refer to ncurses correctly -- that might be the case... Anyway, replacing these three `==' by `=' (which I did now) fixes the whole problem, right? (Or just this symptom?)

Do you compile the files with `--autobuild', then `ar' together the resulting objects, or do you use `--autobuild' without `ar'? What happens if you just link the object files? Does it make any difference whether they were compiled with `--autobuild' or `--automake'?

Hi Frank symptom: GPC would compile unit crtc.c but wouldn't link to ncurses so used text editor to search the Makefile.in files for == and replace with = when it appeared in an "if" statement then did cnfigure, etc, etc result: gpc now finds ncurses (bash defaults to always false when it sees == ) ---------- > From: Frank Heckenbach <frank(a)tim.gerwinski.de> > To: gpc(a)gnu.de > Subject: Re: Fw: gcc-19990330 > Date: Sunday, May 09, 1999 7:02 AM > > Once upon a time ago, Russ Whitaker wrote: > > > > near the end of make LANGUAGES=pascal there is a number of "if" > > > statemnets followed by the message > > > > > > /bin/sh: [: ==: binary operator expected > > Unless this has already been solved, can you give more information > where this accurs (perhaps a log of the make run)?

Global variables problem
by Ian Thurlbeck 07 May '99

07 May '99

Dear GPC-ers It's a while since a reported a bug in gpc, but hopefully this one is just me being stupid (again). I have a main program and a library program which share some global variables and I want to set the variable in the main program and print them out from the library program: ------main.p--------- program main(input,output); #include "main.h" begin global_int:=100; global_str:='Goodbye World'; print_globals; end. -------------------- ------lib.p----------- module lib(input,output); #include "main.h" var global_int:integer; global_str:string(40); procedure print_globals; begin writeln('global_int=',global_int); writeln('global_str=',global_str); end; end. ------------------- ------main.h-------- var global_int: external integer; global_str: external string(40); procedure print_globals; external; ------------------- Fairly straightforward, but I get: ida globals/ % gpc -o main main.p lib.p ida globals/ % main global_int=100 global_str= Not time to say goodbye yet, it seems. If I move the declarations of the global variable from lib.p to main.p I get: ida globals/ % main global_int=100 global_str=Goodbye World Success, but why ??

What would probably be the best thing to do is internationalise the Pascal compiler with GNU gettext and then translate all the warning and error messages into various languages. > Just one thing to take into account: The GNU Pascal > documentation is currently fairly incomplete. If you find > a missing section, be welcome to add it. Translating all the GNU Pascal documentation into another language can create a maintenance headache as you have to try and keep track of the alterations that will be made to the document. Certainly a one-off translation would probably be good, but trying to keep it up-to-date is likely to be more trouble than it is worth. Nick.

So perhaps this list should insert a reply-to-the-list header be default? Peter, can the mailing list software do that? Is that desirable?

My apologies, my MUA puts in a reply-to header by default, I've never needed to remove it on any other mailing list, but looking at mail from those most of them appear to re-write the reply-to header to be the mailing list submission address.
