Re: [Mingw-users] error with the zlib mingw port

I assume you mean this:
http://downloads.sourceforge.net/mingw/zlib-1.2.3-mingwPORT-1.tar.bz2

and that you will be building from:
http://www.zlib.net/zlib-1.2.3.tar.bz2

That port has been built with an older (broken) version of portmaker,
which causes it to try to

  cd /usr/src/zlib-1.2.3/..

*before* the /usr/src/zlib-1.2.3 parent has been created.  This `cd'
command fails, resulting in failure of the port.  To work around this
you must

  mkdir -p /usr/src/zlib-1.2.3

*before* you run `mingwPORT.sh'.  Assuming that you've done that, then
this port should build ok.  I've just run it, as above, and I cannot
reproduce this:

Even when I didn't create the parent source directory first, I don't
see this symptom; it fails long before it gets this far.  When I do
create the directory first, it all builds cleanly for me.

It is curious that dllwrap says `CreateProcess: No error', and then
proceeds to terminate abnormally; seems to point to a possible bug
in dllwrap, bug it's going to be well nigh impossible to track it
down, if we can't reliably reproduce it.

Can't think of anything, beyond a full MinGW install, and MSYS; you
might also like to install the msysDTK, but I don't think that it is
really necessary -- your failure appears to be associated with a tool
which is provided by the MinGW install.

Sorry, can't be more helpful.

Keith.
