Re: Undefined symbol __eprintf in libaudiofile.so (Gnome ticket reportlogs - #6056)

This is interesting. I'm starting to wonder if the wacked-out version of GCC from
sunfreeware.com is schwartz'd.  I export that environmental, configure breaks ;-)

../xmms-1.2.3$ export LIBS="-R/usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.2
-lcc1plus"
../xmms-1.2.3$ ./configure
creating cache ./config.cache
checking host system type... sparc-sun-solaris2.7
checking for a BSD compatible install... ./install-sh -c
checking whether build environment is sane... yes
checking whether make sets ${MAKE}... yes
[...]
checking build system type... sparc-sun-solaris2.7
checking for ranlib... ranlib
checking for gcc... /usr/local/bin/gcc
checking whether the C compiler (/usr/local/bin/gcc -msupersparc -O9 -fPIC )
works... no
configure: error: installation or configuration problem: C compiler cannot create
executables.

So I:

$ make distclean
$ unset CC CFLAGS LIBS
$ ./configure; make

This time I watch closely as it compiles Output/esd.  I see a large error scroll
past, so when it completes, I go back to xmms/Output/esd

$ make clean
$ make

And here is this is error, which is rather similar to an error I was receiving from
a graphics library related to GNOME

In the makefile, It has:

ESD_LIBS = -L/usr/local/lib -lesd -laudiofile -lm -lresolv -lrt -lnsl -lsocket
-L/usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.2 -lgcc
LIBS = -lposix4

if I change

ESD_LIBSS to .... -lcc1plus
&
libesdout_la_LIBADD = ... -lcc1plus

I get the same thing....
