[CMake] RE: Cygwin cmake - Could not find CMAKE_ROOT

Mon Oct 8 16:56:02 EDT 2007

David,

/bin is before /usr/bin in my path.  My .bashrc file was created so long
ago, and changed so many times that it is impossible to know why this is
so.

I think the bigger issue here is that it is not forbidden to put /bin
before /usr/bin in your path.  For whatever reason, I'm sure a lot of
people have done that.  For them, cygwin cmake may not work.

To answer your questions ...

% which cmake
/bin/cmake
% type -a cmake
cmake is /bin/cmake
cmake is /usr/bin/cmake
cmake is /cygdrive/c/Program Files/CMake 2.4/bin/cmake
% echo $PATH
/cygdrive/d/home/wheeler/etc/bin:/bin:/usr/bin:/lib/lapack:/usr/X11R6/bi
n:/etc:/sbin:/usr/sbin:/usr/local/bin:/cygdrive/c/Program Files/CMake
2.4/bin/:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/system32

I'll just re-emphasize that cygwin cmake works perfectly for me as long
as I run it via /usr/bin/cmake.

Regards,
Fred

Hmmmm....

Well my cygwin PATH starts with:
/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin

Why would the cmake in your "/bin" be chosen over the one in
"/usr/bin"...?

What happens when you type: 
which cmake

What is the value of your PATH environment variable and how did it get
that way...?

	This would be expected given how cygwin sets up these
directories:

	Sounds like the cmake located at "/bin/cmake" is stale/old, but
it's in your path before the one from /usr/bin...

	How did the one at "/bin/cmake" get there?

	Maybe just deleting the cmake-related files under /bin and just
using the officially installed ones in /usr/bin is the solution?

		I'm having trouble running cygwin cmake 2.4.7-2 on two
different
		machines, one running XP, and one Windows 2000.  Here's
the error:

		% /bin/cmake
		CMake Error: Could not find CMAKE_ROOT !!!
		CMake has most likely not been installed correctly.
		Modules directory not found in
		/bin
		     39 [main] cmake 1196 _cygtls::handle_exceptions:
Error while
		dumping state (probably corrupted stack) Segmentation
fault (core
		dumped)

		In each case I've installed cmake using the cygwin
setup.exe installer.
		On the XP machine I just did a reinstall of cmake using
setup.exe, but
		the problem persists.  I'm not sure when this problem
began.  It could
		have started months ago without me noticing.

		/usr/share/cmake-2.4.7/Modules/ is full of .cmake and
other files.
		Looks normal to me.  About 192 files dated "Jul 31
09:51".
		% ls -l /usr/share/cmake-2.4.7/Modules/|wc -l
		194

		I thought maybe I had an environment variable problem.
But if I unset 
		every environment variable I get the same behavior.

		I get the same error in rxvt, and the usual cygwin bash
shell.  But
		cygwin cmake does in fact work (!!!) when run from a DOS
window using:

		  c:\cygwin\bin\cmake 

		I tried running bash, sh, tcsh and zsh from a DOS window
and then
		running /bin/cmake.  In each case - same error.  I never
use tcsh or
		zsh, so I don't have any configuration files for them.

		cygcheck thinks my cmake install is OK (and cygcheck -c
says every 
		installed package is OK)

		% cygcheck -c cmake
		Cygwin Package Information
		Package              Version        Status
		cmake                2.4.7-2        OK

		I updated every installed cygwin package the "current"
version a couple 
		of hours ago.
		% md5sum /bin/cmake.exe
		af465bc5ad9e6157a4898c476bfe62a3 */bin/cmake.exe

		I don't see anything about this problem on the cmake or
cygwin mailing
		lists, so this must be something about my personal setup
on these two 
		machines.  Any help or ideas for solving/debugging this
would be
		appreciated.

		Thanks,
		Fred Wheeler
