Cannot Compile Camstream in Gusty

have you verified the application path? sometimes the installers put items in different places on different distros

Yes, I have verified the application path; it is correct. BTW, I finally found the .profile file; it's in:

/root/.profile

But; there's also a "profile" file, without the preceeding "." located in:

/etc/profiled

And another in:

/home/john/.profile

There may be others as well. Where do the environment variables, specifically PATH, normally get set? There must be a predefined place for this.

Thanks, John

Thanks, John

it depends on the shell that you are using.

bash: use ~/.bashrc

sh, ksh, and derivatives: ~/.profile

Regardless, after making changes, you need to process it. There are two ways:
1. in a terminal enter source ~/.bashrc or ~/.profile
2. close the terminal and re-open.

hope this helps

Oh yeah, I should have mentioned for completeness.

The file /etc/profile sets the environment for all users on the system.

On my system GG 7.10 AMD64, if I open Terminal and execute cd /, there is not a .bashrc file; however, if I click on Computer/FileSystem/root, then I do find a .bashrc file. Is this the right one? Also, should I set $PATH in /root/.bashrc, /etc/profile or do I actually need to create one in /; which I believe would be equivalent to clicking on "Computer/FileSystem?"

I discovered something very interesting as well. I opened Terminal and executed:

"echo $PATH"

which returned the following:

"/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games."

I the used the "Places/Search for Files" feature to locate all files that contained the text listed above and I located the following files:

"/var/lib/dpkg/info/libpam-modules.postinst"

It's text reads"

#!/bin/sh -e

# If the user has removed the config file, respect this sign of dementia
# -- only create on package install.

if [ -z "$2" ] || dpkg --compare-versions "$2" lt 0.99.7.1-3
then
 if ! [ -f /etc/security/opasswd ]; then
  umask 066
  touch /etc/security/opasswd
  umask 022
 fi
fi

# Add PATH to /etc/environment if it's not present there or in
# /etc/security/pam_env.conf
if [ "$1" = "configure" ] && (dpkg --compare-versions 0.79-3ubuntu6 ge "$2" || [ "$2" = "" ]); then
 if ! grep -qs ^PATH /etc/security/pam_env.conf; then
  if ! grep -qs ^PATH /etc/environment; then
   echo 'PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"' >> /etc/environment
  fi
 fi
fi

"/etc/environment"

It's text reads:

"PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
LANG="en_US.UTF-8

It appears that these two files work together to set the environment variables immediately after install. It almost seems like I should just $PATH in these files; however if modifying "/root/.bashrc" is the accepted practice and I want to point it to "/usr/share/qt4/bin," do I just add:

"PATH=/usr/share/qt4/bin"

or do I have to add it to all the other PATH statements such as:

"PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/share/qt4/bin"

or do I have to specify it more like:

"PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/share/qt4/bin:$PATH"
export PATH"

and then:

1. in a terminal enter source ~/.bashrc or ~/.profile
2. close the terminal and re-open.

Do you see how complicated this can be?

Thanks, John

All that said and done; where do I actually locate the folder I want to point "bash" to for the "Qt4" libary, which is multithreaded?

Thanks again, John
