g2calc won't compile

I have tried to compile g2calc version 0.13 created by disciple:

# cd src
# make
yacc -d --report=solved --report=itemset expcalc_par.y
conflicts: 44 reduce/reduce
flex expcalc_tok.l
gcc -c -o y.tab.o y.tab.c
In file included from expcalc_par.y:129:
expcalc_tok.l: In function 'yylex':
expcalc_tok.l:53: error: 'tE' undeclared (first use in this function)
expcalc_tok.l:53: error: (Each undeclared identifier is reported only once
expcalc_tok.l:53: error: for each function it appears in.)
make: *** [y.tab.o] Error 1


Hmmm, I downloaded g2calc original source, it compiles, but it doesn't work -- I click buttons, nothing displays. Oh well.

Hi Barry the orginal sources are located at http://ftp.uk.freesbie.org/sites/ftp.sourceforge.net/pub/sourceforge/g/project/g2/g2calc/g2calc/g2calc-alpha1/g2calc.tar.gz

V12 by disciple http://www.murga-linux.com/puppy/viewtopic.php?mode=attach&id=14131 works if you compile it, you have to manually click the bin file in /scr. If you try to make a .desktop file it doesn't launch, if you run it via terminal it doesn't launch and gives a glade error that it can't find the glade file, only by clicking the bin it works. Very strange calculator.

Sorry Barry,
That's a remnant of my attempts to further improve the expression parsing, but I had a bit of a mixup when I uploaded that version. Very bad form.
It will compile if you delete that line from expcalc_tok.l:
"E" {yylval.double_t = 0; return tE;}

What I hope to do when I get a chance will actually farm everything but the gui out to an existing program, which is well tested and by a competent author. As well as providing arbitrary precision support, this will mean I won't have to worry that I might have stuffed up the maths somewhere and made it produce wrong answers :)

Your problem with the original source is interesting; I've had no problems across a lot of systems, except in Cygwin. I guess something is missing, faulty or incompatible in Qwerky. Does anything display if you use the precompiled binary? Do you know if other glade based programs are working? Galculator perhaps?

> only by clicking the bin it works

You've forgotten, Ttuuxxx :)
It just needs to be started from the right place in relation to the pixmaps and the glade file. It is an unfinished product and a couple of the things that it is lacking are a proper build system and the use of proper file paths :)
The original author wrote it partly because he couldn't find a calculator he liked, and partly to "learn gtk programming"...

G2calc is faulty
disciple,
There is nothing wrong with Quirky. Quirky is happy with other apps that use Glade.

I deleted that line, and it compiled, and it works. I get text in the window. However, if I change to the other glade file, that uses pixmaps, then g2calc once again does not work properly, i.e., no text.

Glade error msg
disciple,
With the normal glade file, g2calc starts and there are no error messages in the terminal. However if I use the glade-with-pixmaps file, then when I start g2calc, a heap of error messsages get displayed, one for each key, like this:

(g2calc:26155): libglade-WARNING **: could not find signal handler 'on_sqrt_button_clicked'.

I didn't update the pixmap glade file for my last version
Yes, my last version has generalised input functions (to save code and allow more flexibility for choosing buttons to put in a glade file) but I only updated the other glade file, not the one with pixmaps, so that currently does not work.

It is interesting that my version works but the original doesn't - my changes were mostly very minor and I didn't really change the underlying methods it was using.

that was because
FYI, the reason I didn't update the pixmap glade file is because I was only really interested in making a file that would include buttons for all the new functions I added, and I rather like the original pixmaps, but Sami (the original author) has forgotten what font he used. I mean to try to identify the font (apparently it was in the Debian version he had at the time), but haven't got around to that either.
