I have created a patch for native/java.net that will let classpath
compile on non-linux systems (i am running on a sun). It will also
get rid of a bunch of silly warning messages. The patch is appended
to the end of this email.
I also noticed a strange warning message when I tried to compile
classpath on a linux box. Here is the warning I got from the
java.net classes.
/bin/sh ../../libtool --mode=compile gcc -DPACKAGE=\"classpath\" -DVERSION=\"0.0\"
-DSTDC_HEADERS=1 -DHAVE_UNISTD_H=1 -DHAVE_GETHOSTNAME=1 -DHAVE_STRERROR=1
-DHAVE_LIBPTHREAD=1 -DUSE_PTHREADS= -I. -I. -I/tmp/mo/install_japhar/include/japhar
-I/tmp/mo/install_japhar/include/japhar/private -g -O2 -c javanet.c

-I/tmp/mo/install_japhar/include/japhar
-I/tmp/mo/install_japhar/include/japhar/private -g -O2 -c javanet.c
javanet.c:37: warning: #warning Neither SO_TIMEOUT or SO_RCVTIMEO are defined!
javanet.c:38: warning: #warning This will cause all get/setOption calls with that
value to throw an exception
echo timestamp > javanet.lo
/bin/sh: .deps/javanet.p: No such file or directory
make: [javanet.lo] Error 1 (ignored)
Is this a known problem?
hope that helps
