unable to switch to gcc 4

[Hans Horn-2]

Folks,

I was trying to make the switch gcc3 -> gcc4

before:

$ gcc --version
gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
Copyright (C) 2004 Free Software Foundation, Inc. ...


$ /usr/bin/set-gcc-default-4.sh


after:

$ gcc --version
gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
Copyright (C) 2004 Free Software Foundation, Inc. ...

$ ls -lt /usr/bin/gcc*

-rwxr-xr-x  3 Hans root  1220622 Sep 28 19:18 /usr/bin/gcc-4.exe
-rwxr-xr-x  1 Hans root    16984 Sep 28 19:03 /usr/bin/gccbug-4
lrwxrwxrwx  1 Hans None        9 Jul 14 16:30 /usr/bin/gcc.exe -> gcc-3.exe
-rwxr-x---+ 1 Hans Users   94741 Feb 25  2009 /usr/bin/gcc-3.exe
-rwxr-x---+ 1 Hans Users   16261 Feb 25  2009 /usr/bin/gccbug-3


Am I stupid or what gives?
Kindly,
H.

I think gcc4 is invoked as gcc-4.  I usually set up a softlink in my search path.

I think I figured it out myself; seemingly I need to have
/etc/alternatives in my path before /usr/bin.

Now I get:
$ type gcc
gcc is /etc/alternatives/gcc

$ gcc --version
gcc (GCC) 4.3.4 20090804 (release) 1 ...

greets,
H.

No, that shouldn't be necessary. Thes issue is with this:

lrwxrwxrwx  1 Hans None        9 Jul 14 16:30 /usr/bin/gcc.exe -> gcc-3.exe

That link should be pointing to /etc/alternatives/gcc. It does here anyway.

I had a similar problem (reported 2 weeks ago) with a different picture.
In my case, /usr/bin/gcc was not a link at all, but a copy of gcc-3.exe,
although /usr/bin/g++ had been properly installed as a link. Fixed this
manually.
This might be an indication that either the script set-gcc-default-4.sh
or its installation
may be somehow unreliable.
