Compiling SpellChecker on linux

BlueHazzard:
Hi,
if i try to compile the SpellChecker plugin on linux i get linker errors:

I have to modify the linker commands to this to be able to compile

--- Code: ---`$(WX_CONFIG) --libs`
-lwxSpellChecker
`pkg-config hunspell --libs`

--- End code ---

oBFusCATed:
What is the difference in command lines between the two?

BlueHazzard:
Hundspell  and wxSpellChecker change place...
Not working:

--- Code: ----lhunspell-1.6  -lwxSpellChecker
--- End code ---
Working

--- Code: ----lwxSpellChecker -lhunspell-1.6
--- End code ---
So the order matters for gcc (as we all know...)

oBFusCATed:
It matter for the linker and not GCC! I guess it is safe to commit it. But for me it works fine. No idea why for you it doesn't work.

BlueHazzard:

I would like to investigate about this, before i fix a problem that is not there...
As far as i understand the resolving of the symbols by the linker is revers, so if library A needs symbols from library B the library order for the linker has to be

--- Code: ----lA -lB

--- End code ---
And this is the case here: wxSpellChecker needs symbols from hunspell-1.6. Why did it ever worked? Or why did it stopped for me to work? Does someone else also has this problem?.. Does this has something to do with the evaluation order? First the "other linker commands" and then the linker libraries? I use the latest trunk version of codeblocks...
