[Nadeem Akhtar <nadeem@miel.mot.com>]

Hi !!
 I'm installing ns-allinone-2.1b6 on a SunOS platform. When i
run the install script, it exits prematurely with the following error message
:

-gcc -c -O    -I./../generic -I.  -DUSEGETWD=1 -DNO_STRERROR=1 -DNO_GETWD=1 -DNO_WAIT3=1 -DNO_UNAME=1 -DNO_DIRENT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_SYS_SELECT_H=1 -DHAVE_SYS_TIME_H=1 -DTIME_WITH_SYS_TIME=1 -DHAVE_ST_BLKSIZE=1 -DSTDC_HEADERS=1 -DUSE_DIRENT2_H=1 -DNO_UNION_WAIT=1 -DRETSIGTYPE=void -Dvfork=fork -DNO_GETTOD=1 -DHAVE_SYS_IOCTL_H=1 -DHAVE_SYS_FILIO_H=1        -DTCL_SHLIB_EXT=\".so\" ./../generic/tclBasic.c

./../generic/tclBasic.c:3936: for each function it appears in.)
*** Error code 1

I'm at a dead end and need some help asap.

thanx and regards,
