Downloaded grass5.0beta4 compiled for linux...
There seems to be some discrepencies between what the instructions say
for the directory tree name (/usr/local/grass5 - README at Baylor ftp
site) and what some programs expect (/usr/local/grass5.0b).
For instance, create_fifos.sh has these lines:
# create_fifos.sh.in
DEV=/usr/local/grass-5.0b/dev
For portability I suggest:
DEV=`pwd`
When I changed this line, and remade the fifos because I couldn't start
monitors and thought that might be the problem, I discovered that
somewhere the monitors also expected to live under
/usr/local/grass-5.0b. I haven't tracked down where this expectation is
coming from, but I suspect it's hard coded into the files. So, I renamed
the directories and the monitors now work.
Now, if I could get NVIZ to work...It dies at some point when talking to
tk.tcl. Here's the relevant part of strace, if it'll help.
open("/usr/lib/tk8.0/tk.tcl", O_RDONLY) = 5
fcntl(5, F_SETFD, FD_CLOEXEC) = 0
ioctl(5, TCGETS, 0xbfffda84) = -1 ENOTTY (Inappropriate ioctl
for dev
ice)
read(5, "# tk.tcl --\n#\n# Initialization s"..., 4096) = 4096
read(5, "vent add <<Clear>> <Clear>\n }"..., 4096) = 1601
close(5) = 0
brk(0x8110000) = 0x8110000
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
The problem seems to be that ioctl(5,TCGETS,...). Perhaps a system bug?
