configure: error: unable to detect exception model

configure: error: unable to detect exception model

[Josef Zlomek]

Hi,

when I try to make cfg-branch I get this error:

checking for exception model to use... configure: error: unable to detect exception model
make: *** [configure-target-libstdc++-v3] Error 1

Do You know how to solve it?

Thanks.

Update again from CVS.  This should be fixed by:

2001-11-25  Andreas Jaeger  <aj@suse.de>

	* toplev.c (rest_of_compilation): Call
	find_exception_handler_labels.
	Patch by Jan Hubicka <jh@suse.cz>.

Check config.log for details of the problem,

This time it's a different error ;-)

Which commands did you issue exactly?

configure looks in this case for g++ only in the build environment.
If you enabled C++ during bootstrap, everything should work - and if
you disabled C++, libstdc++ should never be build.  Therefore please
tell us what you did so that we can help.

I got the CVS version.
Then "./configure" in the main dir - OK
Then "make" - it made gcc, then started configuring something else and wrote the error

That's not how you should build GCC (according to
http://gcc.gnu.org/install/).  Use a separate build directory and
issue make bootstrap.  For example I run from a separate build dir
(most options are not needed and you can use the default):

/cvs/gcc/configure --prefix=/opt/gcc-3.1-devel --enable-shared \
	 --enable-threads=posix  --enable-clocale=gnu  \
         --with-gnu-as --with-gnu-ld --disable-nls --with-system-zlib
(make  bootstrap && make -k check) 2>&1|tee make-out

I have built gcc into separate dir but it still does not work. I used configure without options.

configure: error: unable to detect exception model

[Josef Zlomek]

Hi,

when I try to make cfg-branch I get this error:

checking for exception model to use... configure: error: unable to detect exception model
make: *** [configure-target-libstdc++-v3] Error 1

Do You know how to solve it?

Thanks.
