Running cygwinb19 and cygwin-1.1 based programs in parallel

Running cygwinb19 and cygwin-1.1 based programs in parallel

[Martin Oberhuber]

Hello,

I need to run some cygwinb19 based compilers (which I have only in
binary form) with my cygwin-1.1 based make system (make, bash etc.).

Since in that case, cywinb19.dll and cygwin1.dll are in memory at
the same time, can I expect the two DLL versions to work together
correctly? - So far, I have not found any problems but I was only
able to do a quick test and I'd like to be really sure.

Thanks for your answer,

Martin

Keep going and you'll find problems.  If you really need to work with
the old compiler toolset (why's that?), remove cygwinb19.dll and copy
cygwin1.dll in its place (i.e. rename it to cygwinb19.dll).  Or, better
yet, pull out your favorite binary editor and edit the executables that
use cygwinb19.dll to use cygwin1.dll.  Mind you, fill in the extra 
characters left over in this operation with spaces, otherwise you'll nuke
your executable.  Still, I think we'd all like to see you use current 
tools, compiler et al.!:-)

Spaces??? Shouldn't that be ASCII 0?

Actually, last time I did this, along time ago, I edited the file with 
vim in the binary mode and "spaces" that I used worked fine.  I expect 
ASCII zero would be OK too, though I haven't tried this.  Regardless, this 
isn't the method for the faint of heart.  Neither is using out-dated 
toolsets!;-)

What compilers don't you have the source for?  Since it is dependant upon
CygwinB19 then it is Open Source and the source should be available as well as
the source for CygwinB19 itself.  We the Cygwin community are interested in
eliminating the old versions of Cygwin existing on the net especially when they
are not in compliance with the license.

You cannot have two differing versions of Cygwin in memory at the same time as
it is shipped out of the box.
