problem with environment variables under linux
Hi all,
I'm trying to set up continuum to work with questa, that is a tool for
system on chip design.
Thus far, I've succeeded to make continuum start as a deamon on linux -
ubuntu 8.04 to be precise.
Apparently it runs as root that way.
The problem I have is that it doesn't seem to see any environment variables.
Neither my PATH or LM_LICENSE_FILE variable are found, apparently.
If I log in as root, and check these variables with echo or export, all is
fine.
I am using makefiles (Shell project), and if I run my makefile manually (not
invoked by continuum), everything works fine, so there is no problem with
the installation of the questa tools, nor with make.
This is the output I am getting after a build:
make: Entering directory
`/opt/continuum/target/working/1/01-basics/solution'
echo /sbin:/bin:/usr/sbin:/usr/bin
/sbin:/bin:/usr/sbin:/usr/bin

Unable to find the license file. It appears that your license file
environment variable (e.g., LM_LICENSE_FILE) is not set correctly.
Unable to checkout a license. Vsim is closing.
** Fatal: Invalid license environment. Application closing.
make: *** [simple-test] Error 4
_______________________________________
This is the PATH that continuum is apparently using (see begin of output) :
echo /sbin:/bin:/usr/sbin:/usr/bin
/sbin:/bin:/usr/sbin:/usr/bin
It's not the path I've set in /etc/environment though...
I've hardcoded the path in the makefile, just for now, so that make does
find the vsim program (part of questa tools).
Also the remark at the end:
Unable to find the license file. It appears that your license file
environment variable (e.g., LM_LICENSE_FILE) is not set correctly.
Unable to checkout a license. Vsim is closing.
This is, I think, essentialy the same problem as with the path variable. It
is also defined in the /etc/environment file, and that works fine as long as
I do it manually without continuum.
I also tried to define the variables in ~/.profile (for root), but to no
avail...
So what is going wrong here ?
I've looked around with google, but didn't find anything usefull.
I'm fairly new to linux, but since the thing works without continuum, I
don't think it is a linux related problem.
No experience with continuum (or any other CI software, fot that matter).
Hope anyone can shed some light on this :-)
Thanks you.
Rudy

you should issue a "su <someUser>" before running your daemon, in your
daemon script. Running snaphshot code and unit test as root user is most
certainly a very bad idea, unless you have very good backups and don't
mind reinstalling that computer several times a day when some developper
makes a mistake manipulating a File("/") in a unit test :)
Thanks for your reply, David.
I just puzzeled out how to start continuum als a deamon from the help
(outdated, since it describes the process for the previous version) on the
site, and that is where I got.
I know that running as root is probably not the best idea, but I'm happy
that the thing is running now. For now security isn't a concern yet.
Still, I appreciate the advice, and will act accordingly.
