Cygwin fresh install imports Windows PATH which includes spaces causing errors

Cygwin fresh install imports Windows PATH which includes spaces causing errors

[Aaron Schneider]

Fresh install of cygwin on c:\cygwin\ is including spaces in PATH, 
causing that cannot execute common tasks,

$ echo $PATH
/usr/local/bin:/usr/bin:/cygdrive/c/Program Files (x86)/PC Connectivity 
Solution:/cygdrive/c/Program Files (x86)/Common Files/Microsoft 
Shared/Windows Live:/cygdrive/c/Windows/system32: and so on

Example:
$ make
Can't find C:\Program on PATH.

The Cygwin version of make would not display "c:" anything.  That's not
a Cygwin path specification and it shouldn't even be possible for a
Cygwin program to see the Windows PATH environment variable.  You must
be running a non-cygwin make.  Spaces in the PATH are acceptable on both
Linux and Cygwin and Windows.

That said, however, make does not deal well with spaces in file
specifications.  If something is actually parsing a PATH environment
variable then it could cause problems.

It was actually that make wasn't installed, it works now. I was 
expecting the usual "bash: make: command not found"

You apparently didn't grok the part about "it shouldn't even be possible
for a Cygwin program to see the Windows PATH environment variable".
Having "c:\Program Files\something" in the PATH is very common on
Windows.  I have it in my path and I don't see anything like this when I
try to run a nonexistent command.  You must have something else going on
if you are getting errors with "c:" in them.  If you saw this error then
you likely aren't using a Cygwin shell.

If you have further problems then you should (re)read
http://cygwin.com/problems.html .  Your takeaway from that would
probably be that you need to send cygcheck output as an attachment but
the real reason for that web page is to start you thinking about how to
send a problem report.  Sending an error message with no other
supporting details is not the most efficient way to get a problem
solved.

You're right, I know what caused the problem, a window's system path 
(not user's path) that includes the make.exe

c:\Program Files (x86)\Common Files\Symbian\tools\make.exe

Since  there wasn't /usr/local/bin/make or /usr/bin/make just searched 
on paths imported from windows.

There'd be a /bin/make if you installed it...

    $ which make
    /bin/make

IMHO it's always better to go with a Cygwin way of doing things instead 
of installing some Unix/Linux thing through some Windows port like this 
Symbian\tools thing...

That make.exe was installed by Symbian Qt SDK which is windows native, 
nothing to do with cygwin. In fact, that make.exe calls a perl script 
called make.pl:

use FindBin;
use lib $FindBin::Bin;
use tlaunch;
callTool('','\\epoc32\\tools\\make.exe',\@ARGV);

So anyway, the problem is caused when calling a binary present on 
windows path that can match a cygwin one, for example running a 
./configure script.
  After removing make the issue is happening again:

$ make
cygwin warning:
   MS-DOS style path detected: /usr/local/bin/C:\Program
   Preferred POSIX equivalent is: /usr/local/bin/C:/Program
   CYGWIN environment variable option "nodosfilewarning" turns off this 
warning.
   Consult the user's guide for more details about POSIX paths:
     http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
Can't find C:\Program on PATH.

And, IMHO, should be avoided like the plague... Just my opinion.

Maybe when in Cygwin, /bin and /usr/bin should be put in your PATH ahead 
of the Windows stuff. I know I've run with C:\Cygwin\bin in the front of 
my Windows System Environment PATH variable for years without issue 
(though I think some around here might say it's not a good idea).

They are already in front, but if the command is not there it just 
searches for the next up to the last, and if no match even so, says 
command not found.

Which is why I said eariler: IMHO it's always better to go with a Cygwin 
way of doing things instead of installing some Unix/Linux thing through 
some Windows port like this Symbian\tools thing...

Of course you have to actively know what you want to use and what you 
have. I assume, since you typed the command make in your initial posting 
on the problem you would have known that you wanted to execute make and 
that you would have thought "Gee I'd like to execute Cygwin's make" and 
perhaps would have checked with a "which make" or a "type make" and, 
upon finding you don't have Cygwin's make, the initial question would 
have been "Where's make" (or you would have went to 
http://cygwin.com/packages/ and searched for make.exe and just solved 
your own problem without questioning) not "Cygwin fresh install imports 
Windows PATH...".

Could this be a problem with the Makefile? It looks like you're using
Cygwin make now, but the Makefile might be calling out Windows paths
directly...

Oh no I meant I removed the cygwin's make, the nokia's make is still 
present, never removed it in the end. The makefile is in perfect 
condition, even I tried it on a empty dir and the result is the same.

If you're not using the Cygwin tools including make then we cannot
help you with the problem.  The only resolution is to install the
Cygwin make to overcome the issue.  But this also means that the
Makefile must conform to POSIX paths.

There's nothing to "solve" actually, I removed from PATH the paths that 
are no longer useful to me, among those that Symbian one that I no 
longer use.
