Hm, sounds like an install of the "optional software" CD (or whatever
it's called) that comes with the OS - right? I happen to have such a box
here - yup, I can reproduce your problem.

Even stranger is that erl_interface's configure script (run earlier) had
no problem doing the same thing (maybe the result should be cached:-).
Anyway, this seems to be a case of "broken gcc installation" - I haven't
tried it with a "proper" one on Solaris 8, but I assume that you
have.:-)

Configure *usually* works well, but it's also notorious for drawing
altogether the wrong conclusions when its tests fail in "unexpected"
ways - usually config.log tells the real story in those cases, but here
even that was basically silent, just said that the test program "failed"
w/o giving any error messages. So we have to try to reproduce what it
did (this is the "sizeof short" test):

$ gcc -o conftest -g -O2 -I/var/tmp/otp_src_R9C-0/erts/sparc-sun-solaris2.8 conftest.c -lncurses -lresolv -ldl -lm -lsocket -lnsl
$ ./conftest
ld.so.1: ./conftest: fatal: libncurses.so.5: open failed: No such file or directory
Killed

I.e. what is happening is that libncurses is found at compile time but
not at run time, which on Solaris typically means that you used -L to
point to some non-standard directory, but not the corresponding -R to
point the runtime linker to the same place. And this is what this *gcc
installation* does - adding -v to the options above reveals that it
passes -L/opt/sfw/lib to 'ld' (but no -R), and that is indeed where
libncurses is found.

Per above, I'd recommend a reinstall of gcc (e.g. build from source),
but it's possible to work around by hack^H^H^H^Husing LD_LIBRARY_PATH:

$ env LD_LIBRARY_PATH=/opt/sfw/lib ./conftest
$ cat conftestval 
2

Doing the build this way means that you will have to use the same method
also when running the system, though. Alternatively you can read crle(1)
and apply.
