Hi Barb, Sorry for the late response. I just came back from my vacation. Unfortunately, the problem is still there. It most likely caused by the upgrade of Solaris version because I can succesfully 'make' the glomosim on 'eru' and 'linux'. The current glomosim is getting obsolete because it has not been updated since 2001. The following is the message I got when I make the glomosim code on 'zerg' for your reference: hhsu@zerg:/home/users1/hhsu/glomsimT/glomosim/main> make pcc -g -O3 -I../include/ -I../transport -I../transport/tcp -I../application -I../mac -I../main -I../network -I../radio -I../../parsec/solaris-gcc303/include/ -clock longlong -lm -c ../main/glomo.pc In file included from /usr/include/iso/stdarg_iso.h:41, from /usr/include/stdarg.h:32, from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/include/stdio.h:14, from ../../parsec/solaris-gcc303/include/pc_api.h:39, from /tmp/tmp-9532.c:1: /usr/include/sys/va_impl.h:150:2: #error ("Unrecognized compiler protocol for variable argument lists") Failed preprocessing '../main/glomo.pc'. pcc -g -O3 -I../include/ -I../transport -I../transport/tcp -I../application -I../mac -I../main -I../network -I../radio -I../../parsec/solaris-gcc303/include/ -clock longlong -lm -c ../main/mobility.pc In file included from /usr/include/iso/stdarg_iso.h:41, from /usr/include/stdarg.h:32, from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/include/stdio.h:14, from ../../parsec/solaris-gcc303/include/pc_api.h:39, from /tmp/tmp-9539.c:1: /usr/include/sys/va_impl.h:150:2: #error ("Unrecognized compiler protocol for variable argument lists") Failed preprocessing '../main/mobility.pc'. pcc -g -O3 -I../include/ -I../transport -I../transport/tcp -I../application -I../mac -I../main -I../network -I../radio -I../../parsec/solaris-gcc303/include/ -clock longlong -lm -c ../main/mobility_waypoint.pc In file included from /usr/include/iso/stdarg_iso.h:41, from /usr/include/stdarg.h:32, from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/include/stdio.h:14, from ../../parsec/solaris-gcc303/include/pc_api.h:39, from /tmp/tmp-9546.c:1: /usr/include/sys/va_impl.h:150:2: #error ("Unrecognized compiler protocol for variable argument lists") Failed preprocessing '../main/mobility_waypoint.pc'. ... etc. Thanks for your help. > Hung-Yuan Hsu, > Are you still having problems compiling Glomosim on the machines in 218 IST? > Barb Einfalt > CSE IT Support
