BaCon on Mint 16 (Cinnamon)

[alexfish]

Hi All and & Peter

Found a problem . think what I be mentioning goes further ...

Thought would try Mint Cinnamon a try think this is a bit of a show stopper.

Installed Bacon .. crank up the Gui . type some code then compile :

have tested a simple gtk gui with a button in (c) using dlopen , guess what = same result
Think this may also confirm what was happening on the BASM thread RE:: Vovchik.

also think that the problem lays in calling a second function from within the callback ?? not confirmed . but foe me this it where it happens

BaCon and BaCon.sh work fine.

Oops there goes another rubber tree plant.

will now try and see what happens with hug

Alex

Update , 1. on c code looking at a free within the function .. = corruption. as above.

Dear Alex,

Yes, BaconGui bombs if you try to compile with it. I thought it was my perculiar installation. Fortunately, I use Geany and my own script, so I never reported the problem, figuring it was of my own making. Good thing you did.

With kind regards,

Hi Vovchik

think the problems run deeper than that.

just been going though own tests using .so lib with dlopen in (c) RE try to find this segfault on label RE BASM thread
guess what happens.

no more testing that side , peed off with it.

think need to some more testing on hug to see what happens there , although the Edit buffer looks ok.

also found gedit is in a mess , cant find certain bits . as regards source view.

Happy days

Thanks for reporting Alex!

For the Cinnamon version I will look at the issue to see if I can reproduce it.

Hi Alex,

I guess I was sleeping because the Linux Mint 16 version is notorious for its GTK version. Also the XFCE or MATE edition show the same problem, particularly where the BaConGUI implementation needs to use the EXEC$ function.

There are some vague reports about the strange GTK2 behavior in Linux Mint 16. When I used Mint16 myself I did put some effort into solving this problem (but to no avail), and when compiling GTK2 manually myself I eventually got the BaConGUI running.

Note that BaConGUI runs well in a default install of Mint 13, 14, 15 and 17.x.

I guess it safely can be concluded that there is an issue with GTK2 only in Mint16.

Anyway, I hope you are able to upgrade GTK or your whole Mint installation altogether as this will solve the problem.

Hi Peter

have tested bacon + hug RE button callback + change label , this works

looks like the old dog is back IE where a call to the bin child gives the ID , in c the original at call is not stored
BaCon stores the original ID in the assoc array ,hence it works , also hence that side confirms the 99 bang theory, or in case of gtk version 1 bang and it gone

so happy to stay on cinnamon for a while longer `as regards further testing', still have the original mate install , got that one working
to some degree of satisfaction , here only looking as regards devs.

think U need to have a look at the exec and sys calls , if used in code then there are compile errors .re bacon.sh and bacon. do these calls work on Mint 17. think also could be a problem with bacon.sh + proto , need to look further , then if not of my making ,will post update.

Update exec and sys fine , did a typo quotes missing , highlight editor helps ,

also noted bacon gui highlighting not working either.

fix:: Intsall
`gedit-plugins' then bacon gui syntax highlight works

to get Gedit highlighting working

from the terminal

cd /home/alexfish/.local/share/gtksourceview-2.0/language-specs
sudo cp ./bacon.lang /usr/share/gtksourceview-3.0/language-specs/bacon.lang
sudo cp ./bacon.lang /usr/share/gtksourceview-2.0/language-specs/bacon.lang

Hi all

after installing plugins for Gedit RE source view looks like got a success with bacon gui 3.0.2

did a fresh compile and install .

now the gui is working. up-to now . but I still be puzzled as to why . one thing I did try was install pluma . but dat thing needs the whole shebang
of mate desktop to fire up . Bagh...


anyway , now need to see how stable this is... in as much the way Bacon keeps track of the ID's of the widgets

Hi Peter

Think can Confirm your finding Statements RE: Post 5

Also 'more or less Concluded' there are other Issues as well.
