Error loading functions: /usr/local/libexec/singularity/functions

[George Zaki]

Hi singularity group,

I have installed singularity from source as mentioned in the documentation:

git clone https://github.com/singularityware/singularity.git
cd singularity
./autogen.sh
./configure --prefix=/usr/local
make
sudo make install

Then when I try to call the executable I get the following error:

singularity Error loading functions: /usr/local/libexec/singularity/functions

I can see that this directory: /usr/local/libexec/singularity/ has 700 permission.

Am I missing something?

Thanks and regards,
George.

P.S. I am running CentOS Linux release 7.3.1611

Hi George!  That is indeed unusual.  Could there be anything strange about your umask or the umask of root on your system?

Thanks David. I changed the umask for root and it is happier now.

Now I run in two other issues.

1- Bootstrap:

$ sudo singularity bootstrap candle.img candle.def
sudo: singularity: command not found

So I change to sudo:

$sudo su

$which singularity
/usr/local/bin/singularity

Then I bootstrapped the image correctly.

2- Exec:

I switch back to my user account and I try:

$singularity exec root-candle.img stc
/.singularity.d/actions/exec: 5: .: Can't open /.singularity.d/env/90-swift.sh

However with sudo I get:

$ sudo su
$ singularity exec root-candle.img stc
No input file was specified!
Use 'stc -h' for help.

I added /user/local/bin to my sudoer path so point 1 is resolved.

Sounds like your definition is making a file called /.singularity.d/env/90-swift.sh (that maybe has wrong permissions?) And then when Singularity tries to source that file during startup it fails when you are a normal user?  What does your definition file look like?  (I feel like maybe I should already know lol).

Hi David, 

Point 2 is also solved after I bootstrapped again using sudo singularity bootstrap.

Thanks for your help.

Best regards,

George.

Awesome.

George.
