[Mingw-users] about dll

[Lloyd D. <Llo...@wa...>]

i lost the thread i will to answer to.
anyway it ask why using this useless DLL ?

someones answer it shrink your executable, it's nice, someother  
answer that using third parties DLL (instead of static lib) let you  
be up to date when this third parties upate their code.

but, much more important. you cannot safely mix dll/static lib.
if you have two dll, let me called them a.dll, b.dll which together  
statically link with a static lib, let it called libstdc++.a they  
both have their own private copy of globally exported symbol.
this does't matter or function, but it is a true problem for global  
variable.

i don't really now the intern of exception but i guess, as i easily  
do it this way in pure C, that there is a common exception table of  
address holdig setlongjmp data. and an exception pick data in it.
so when you use dll and static lib you cannot make your exception  
cross your dll up to your executable as it will have no data in your  
executable's exception table !!!!!!!!

so i advice you, to prevent such problem write program either  
without DLL at all or exclusively using DLL.
