Install Software |
||||
================ |
||||
|
||||
There are prebuilt software packages in the repositories, look in |
||||
https://repository.mrw.sh for your operating system. |
||||
|
||||
Note: PublicKey has changed on Novmber 1st 2015, please import the new |
||||
key. |
||||
|
||||
Linux |
||||
----- |
||||
|
||||
There are package repositories for most distributions at https://repository.mrw.sh. |
||||
|
||||
### Ubuntu and Debian |
||||
|
||||
To accept my signature, install my key: |
||||
|
||||
wget -O- https://repository.mrw.sh/PublicKey \ |
||||
| sudo apt-key add - |
||||
|
||||
You can install all software using your package manager (`apt`), first install the repository: |
||||
|
||||
sudo apt-get install -y wget software-properties-common apt-transport-https |
||||
sudo apt-add-repository https://repository.mrw.sh |
||||
sudo apt-get update -y |
||||
Then you can install any project you wish, e.g. [`webtester`](https://mrw.sh/development/webtester): |
||||
|
||||
sudo apt-get install webtester -y |
||||
|
||||
### OpenSUSE |
||||
|
||||
To accept my signature, install my key: |
||||
|
||||
wget https://repository.mrw.sh/PublicKey |
||||
rpm --import PublicKey |
||||
|
||||
You can use your packagemanager (`zypper` or _YaST_). First install the repostitory: |
||||
|
||||
zypper ar https://repository.mrw.sh/opensuse/marc-waeckerlin.repo |
||||
|
||||
Then install packages from the repository, e.g. [`webtester`](https://mrw.sh/development/webtester): |
||||
|
||||
zypper install webtester |
||||
|
||||
In case of trouble: Check if your version of OpenSUSE is supported, |
||||
use `lsb_release -rs` to get the version of your OpenSUSE: |
||||
https://drepository.mrw.sh/opensuse |
||||
|
||||
### Fedora |
||||
|
||||
To accept my signature, install my key: |
||||
|
||||
wget https://repository.mrw.sh/PublicKey |
||||
rpm --import PublicKey |
||||
|
||||
You can use your packagemanager (`dnf`). First install the repository: |
||||
|
||||
dnf install 'dnf-command(config-manager)' |
||||
dnf config-manager --add-repo https://repository.mrw.sh/fedora/marc-waeckerlin.repo |
||||
|
||||
Then install packages from the repository, e.g. [`webtester`](https://mrw.sh/development/webtester): |
||||
|
||||
dnf install webtester |
||||
|
||||
In case of trouble: Check if your version of Fedora is supported, use `lsb_release -rs` to get the version of your Fedora: https://repository.mrw.sh/fedora |
||||
|
||||
### CentOS |
||||
|
||||
To accept my signature, install my key: |
||||
|
||||
wget https://repository.mrw.sh/PublicKey |
||||
rpm --import PublicKey |
||||
|
||||
You can use your packagemanager (`yum`). First install the repository: |
||||
|
||||
yum install wget |
||||
wget -O/etc/yum.repos.d/marc-waeckerlin.repo https://repository.mrw.sh/centos/marc-waeckerlin.repo |
||||
|
||||
Then install packages from the repository, e.g. [`webtester`](https://mrw.sh/development/webtester): |
||||
|
||||
yum install webtester |
||||
|
||||
In case of trouble: Check if your version of CentOS is supported, use lsb_release -rs to get the version of your CentOS: https://repository.mrw.sh/centos |
||||
|
||||
### Mageia |
||||
|
||||
To accept my signature, install my key: |
||||
|
||||
wget https://repository.mrw.sh/PublicKey |
||||
rpm --import PublicKey |
||||
|
||||
You can use your packagemanager (`dnf`). First install the repository: |
||||
|
||||
dnf install 'dnf-command(config-manager)' |
||||
dnf config-manager --add-repo https://repository.mrw.sh/mageia/marc-waeckerlin.repo |
||||
|
||||
Then install packages from the repository, e.g. [`webtester`](https://mrw.sh/development/webtester): |
||||
|
||||
dnf install webtester |
||||
|
||||
### Other Linux Distributions |
||||
|
||||
Either use the nearest possible distribution, or use alien to convert from another distribution to your preferred package format, or compile the project yourself (see below). |
||||
|
||||
Windows |
||||
------- |
||||
|
||||
Download from https://repository.mrw.sh/windows |
||||
|
||||
MacOSX |
||||
------ |
||||
|
||||
You need e.g. Mac Ports to compile. Install the following dependencies: |
||||
|
||||
sudo port install subversion svn2cl doxygen graphviz cppunit libtool boost log4cxx qt5-mac |
||||
|
||||
Fix libtool-bug: |
||||
|
||||
sudo ln -s /opt/local/bin/glibtoolize /opt/local/bin/libtoolize |
||||
|
||||
Compile from Source |
||||
------------------- |
||||
|
||||
For all unsupported operating systems, including MacOSX. |
||||
|
||||
To compile, please download the tar-sources from: https://repository.mrw.sh/sources |
||||
|
||||
Then untar the package and use the common commands, e.g. for version `1.0.2` of a project named project, that means: |
||||
|
||||
tar xzf project-1.0.2.tar.gz |
||||
cd project-1.0.2 |
||||
./bootstrap.sh |
||||
./configure |
||||
make |
||||
sudo make install |
||||

# |

# SYNOPSIS |
||||
# |
||||
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional]) |
||||
# |
||||
# DESCRIPTION |
||||
# |
||||
# Check for baseline language coverage in the compiler for the specified |
||||
# version of the C++ standard. If necessary, add switches to CXX and |
||||
# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard) |
||||
# or '14' (for the C++14 standard). |
||||
# |
||||
# The second argument, if specified, indicates whether you insist on an |
||||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. |
||||
# -std=c++11). If neither is specified, you get whatever works, with |
||||
# preference for an extended mode. |
||||
# |
||||
# The third argument, if specified 'mandatory' or if left unspecified, |
||||
# indicates that baseline support for the specified C++ standard is |
||||
# required and that the macro should error out if no mode with that |
||||
# support is found. If specified 'optional', then configuration proceeds |
||||
# regardless, after defining HAVE_CXX${VERSION} if and only if a |
||||
# supporting mode is found. |

# AX_REQUIRE_STDCXX_11 |

# AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional]) |

# AX_CXX_COMPILE_STDCXX_14([ext|noext],[mandatory|optional]) |
||||
# |
||||
# DESCRIPTION |
||||
# |
||||
# Check for baseline language coverage in the compiler for the C++11 |
||||
# or C++14 standard; if necessary, add switches to CXXFLAGS to |
||||
# enable support. |
||||
# |
||||
# The first argument, if specified, indicates whether you insist on an |
||||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. |
||||
# -std=c++11). If neither is specified, you get whatever works, with |
||||
# preference for an extended mode. |
||||
# |
||||
# The second argument, if specified 'mandatory' or if left unspecified, |
||||
# indicates that baseline C++11 support is required and that the macro |
||||
# should error out if no mode with that support is found. If specified |
||||
# 'optional', then configuration proceeds regardless, after defining |
||||
# HAVE_CXX11 if and only if a supporting mode is found. |
