Summary: Mac OS 10.1: unobvious: --with-suffix

Initial Comment:
First attempts to install Python-2.2b2 under Mac OS 
10.1 on a HFS+ filesystem failed at the point of 
linking the python executable. When browsing 
comp.lang.python it became clear that the --with-
suffix=.exe configure option has to be used. 
Currently, configure only reports:

checking for executable suffix... no
checking for --with-suffix...

It would be a big improvement if configure could issue 
a very visible warning, or even better, supply the 
suffix automatically and tell the user at the very end 
that python is python.exe.

Thanks!
        Ralf

Fixed in the CVS tree: we now check wether we're building on a case-insensitive file system, and if that is the case we add a .exe suffix to python, but only to the copy in the build directory. The installed binary doesn't get the suffix.

I cannot even see the warning when I am looking for it. A 
full output of running 2.2b2 configure under MacOS 10.1 is 
available at this location:

http://cci.lbl.gov/~rwgk/tmp/MacOS10.1_Python-
2.2b2_configure_output.txt

Is the warning in there?

> Would you happen to know of a way to test for this?

You could simply try to detect the very feature that is 
causing the default build to fail:

1. Create an empty file with some dummy, lowercase name:

        touch zap

2. Now test the existence of the file under the uppercase 
name:

        test -f ZAP

3. On HFS, $status == 0, on UFS or NFS, $status == 1.

Yes, this is a serious problem. Configure _does_ give a warning, but it gets lost in the stream of output it
produces.

The problem is that I don't know how to test whether we're building on an HFS+ filesystem. Only then should
we add the --with-suffix automatically, if you're building on a UFS or NFS filesystem there is no problem.

Would you happen to know of a way to test for this? Or should I simply always use --with-suffix on OSX?
