I am trying to build singularity image in centOS linux. to do so I have make the following Singularity.recipe:
Bootstrap: yum
OSVersion: 7
MirrorURL: http://mirror.centos.org/centos-%{OSVERSION}/%{OSVERSION}/os/x86_64/
Include: yum
%post
yum -y install epel-release
yum -y install python34
%file
QC.py /
%runscript
python3 /QC.py
and then I used this command to build the image:
sudo singularity build test.simg Singularity.recipe
but I gave this error:
FATAL: Unable to build from Singularity.recipe: while parsing definition: Singularity.recipe: invalid section(s) specified: file
do you know how to solve the problem?
As the error message says, %file is not a valid section name. The correct section name is %files.

I have singularity-ce version 3.10.2 on ubuntu 20.02. I am trying to install python package. It always says
Singularity> apt-get -y update
bash: apt-get: command not found
I already have python on my local computer. How can I resolve this?
When I try to install mono-complete, it says that the target is not found.
I've tried using just mono, but when I do that, it says that the command is not found. I'm using Arch Linux on an OVH VPS.
pacman -S mono-complete
This Returns:
error: target not found: mono-complete
I'm trying to install this so that I can access mono commands, but I cannot seem to get it installed.
Install mono package
sudo pacman -S mono
I have RedHat Enterprise Linux Server 7, and I downloaded the linux kernel version 4.12.10 which I am trying to compile but when I execute the following command:
make modules
I get the following error:
scripts/sign-file.c:25:30: fatal error: openssl/opensslv.h: No such file or directory
Does anyone have an idea to fix this please ?
To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.
To install OpenSSL development package on Debian, Ubuntu or their derivatives:
$ sudo apt-get install libssl-dev
To install OpenSSL development package on Fedora, CentOS or RHEL:
$ sudo yum install openssl-devel
Edit :
As #isapir has pointed out, for Fedora version>=22 use the DNF package manager :
dnf install openssl-devel
For Alpine Linux:
apk add openssl-dev
On CYGwin, you can install this as a typical package in the first screen. Look for
libssl-devel
for resolving this issue install:
# yum install openssl openssl-devel
and then try again to do make bzImage.

Libsodium has been prepped for PHP 7. In doing this, the namespace was removed and a prefix of sodium_ for methods and SODIUM_ for constants was added. Also the version methods were removed.
This github page documents all the new functions and constants and the project provides backward compatibility with the \Sodium namespace: https://github.com/Firehed/sodium/blob/master/src/we_cant_have_nice_things.php
Recipe: install Libsodium on PHP 7 on and AWS AMI
# PHP 7.0 Libsodium install AWS AMI
yum install -y php7-pear re2c php70-devel
yum groupinstall -y "Development Tools"
pecl7 install libsodium
vi /etc/php-7.0.d/20-libsodium.ini
; Enable libsodium extension module
extension=sodium.so
service httpd restart
command line test to verify sodium is installed
php7 --info | grep sodium
test php function to verify calling pattern for password hash
<?php
$password = "hello";
$hash_str = sodium_crypto_pwhash_str(
$password,
\SODIUM_CRYPTO_PWHASH_OPSLIMIT_INTERACTIVE,
\SODIUM_CRYPTO_PWHASH_MEMLIMIT_INTERACTIVE
);
var_dump($password, $hash_str);
Thanks to #GracefulRestart for the help.
I see a couple problems here, the first is that your test file appears to be non-functional.
Running your test code with libsodium working in PHP 7 returns the following error:
PHP Fatal error: Uncaught Error: Call to undefined function Sodium\\library_version_major()
If you want to check the version, it may be easier to search the data from the phpinfo() function:
<?php phpinfo(); ?>
# or from CLI
php7 --info |grep sodium
The other problem I notice is in your install steps, you install libsodium both from source and from PECL. The make install command by default places the libraries in /usr/local/lib, while pecl7 install libsodium will normally install libraries into the default PHP modules directory.
If you were attempting to install from source, your /etc/php-7.0.d/20-libsodium.ini file is incorrect as that is loading the libsodium libraries you installed from PECL (you can check which directory it is loading from by check the extension_dir ini setting from phpinfo()).
If you only need to install from PECL, you do not need all of the development packages or any manual compiling.
EDIT I modified your posted recipe to remove the extraneous steps of downloading the source and just do everything with PECL:
yum install -y php7-pear re2c php70-devel
yum groupinstall -y "Development Tools"
# PHP 7.0
pecl7 install libsodium
vi /etc/php-7.0.d/20-libsodium.ini
; Enable libsodium extension module
extension=sodium.so
service httpd restart
If the YUM repositories for your distribution offer the php7-libsodium package, that would be an even smaller recipe
Hope that helps
Here's my solution to this recipe.
wget -c https://download.libsodium.org/libsodium/releases/libsodium-1.0.18.tar.gz
tar -xvf libsodium-1.0.18.tar.gz
cd libsodium-1.0.18
./configure
make && make check
make install
sudo pecl7 install -f libsodium
pecl7 should install and modify the php.ini file to include the following in the php.ini
extension="sodium.so"
If you running PHP in Elastic Beanstalk, the following file ./ebextentions/script.config :
files:
"/opt/elasticbeanstalk/hooks/appdeploy/pre/001_libsodium.sh":
mode: "000755"
owner: root
group: root
content: |
#!/usr/bin/env bash
wget -c https://download.libsodium.org/libsodium/releases/libsodium-1.0.18.tar.gz && tar -xvf libsodium-1.0.18.tar.gz && cd libsodium-1.0.18 && ./configure && make && make check && sudo make install && sudo pecl7 install -f libsodium
When installing Apache on Ubuntu 11.10, I get the following error:
configure: error: APR not found. Please read the documentation.
I followed the instructions here, then, I get the error below:
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
What am I doing wrong and how can I resolve it?
1. Download PCRE from PCRE.org
2. Compile it with a prefix and install it:
./configure --prefix=/usr/local/pcre
make
make install
3. Go back to where your Apache installation is and compile Apache with PCRE:
--with-pcre=/usr/local/pcre
For me (Fedora Linux), it was enough to just install the pcre-devel: yum install -y pcre-devel. Didn't even have to use --with-pcre afterwards.
Debian
In a clean installation of Debian 9.5, during the installation of Apache it is necessary to have some packages and libraries to avoid errors. Next I show the type of error and its respective solution
Configuration
configure: error: no acceptable C compiler found in $PATH
$ sudo apt-get install build-essential
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/
$ sudo apt-get install libpcre3-dev
Then I make the configuration indicating that it is installed in the path /usr/local and not in /usr/local/apache2, otherwise I will have library errors. The idea is that the libraries created for httpd end in /usr/local/lib so that the dynamic linker knows them.
$ configure --prefix /usr/local
Compilation
And for the compilation the following the installation of some packages also would avoid us errors in a clean installation of Debian.
xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory.
$ sudo apt-get install libexpat1-dev.
It is recommended to use the -j3 parameter to make the compilation faster. Although it could also be ignored.
$ make -j3
I was other problem compiling apache2 in CentOS with pcre. I installed pcre in other location "/custom/location/pcre" and configure command throw the following error
configure: error: Did not find pcre-config script at "/custom/location/pcre"
to solve it changing the flag --with-pcre=/custom/location/pcre to --with-pcre=/custom/location/pcre/bin/pcre2-config
BTW, on CentOS 7.6 before building httpd, please install pcre-devel
`$ sudo yum install pcre-devel`
In RHEL 3 is not necessary setting parameter --with-pcre pointing to pcre-config. Only need pcre path
My configure command:
./configure --prefix=/usr/local/apache2 --with-pcre=/usr/local/pcre
This worked for me:
sudo apt-get install libpcre3-dev
In ubuntu
This worked for me
./configure --prefix /u01/apache --with-included-apr --with-pcre=/usr/local/pcre/bin/pcre2-config
