'which EXECUTEABLE' is unix command looking up where if anywhere in the path the exectuable is first.
for example:
~/src/wings (dgud/wx-backend):> which ls
/bin/ls.exe
~/src/wings (dgud/wx-backend):>
But as Micheus just said you must have it in your PATH variable to find it,
which btw I don't :-)
A DLL by itsself is not a proper executable. Not at all. Dan ... you have ever used 'which' to locate a DLL ?
No it's not but it is something required by windows to be in PATH.
So it seems to be a mingw/cygwin hack, I don't think it is possible to find .so on unix.
Yes I have, Micheus instructions comes from me or Björn...probably an old readme or something.
~/src/wings (dgud/wx-backend):$> which msys-1.0.dll
/bin/msys-1.0.dll
Interesting ... I went grepping on which to see if I could find this usage which.
FYI ... a DLL does not need to be in path. My personal preference from days gone by
was to use application directory or even explicit load. Using the path can be taking a chance due to
competition for path order.
I had a small time for that...
...let's start again.

that #3 is related to building the ESDL pack. This line:
$ SDL_DIR=/mingw rebar compile
which now a days I'm using:
$ SDL_DIR=/usr/local rebar compile
Take a look on
Readme file in the ESDL repository. You will find:
Quote:...
You need rebar, see: github.com/rebar/rebar
Build with:
rebar compile
On windows:
===========
SDL_DIR=/opt/local rebar compile (requires Microsoft's SDK)
or
CC=gcc SDL_DIR=/opt/local rebar compile (requires mingw)
also copy SDL.dll to esdl/priv dir or put SDL.dll somewhere in your path.
...
So, if it was put "somewhere in you path" the
which command that is able to search into all folders/path/directories included in the
$PATH environment variable will find executables as well as .DLL too (who knows why?)
As the "which" command is ran in the MSys console, the $PATH environment variable is not that one own by Windows, but the one provide by MSys plus the folders we append in the
bash_profile script.
Lets say I had two options and I decided to use that one.
But, I can change it in the tutorial.
Anyway, all repositories have a readme file full of information - and sometimes options. It's a good habit read them.
I know its a hassle Micheus but is now a good time to update the howto dev post to show how to use wxwidgets instead of SDL ?
or can you point me in right direction...
Yeah, an update would be an option.
Until we get it, you can start checking the file named BUILD.??? In the repository root. It's the official guide.
You can just scratch the SDL part, wxWidgets is included in the erlang install on windows.
