I am starting to experiment with conan. I found this GitHub repository but I am not sure what to do with it.
I would like to install log4cxx via conan install.
That github repository belongs to an pre conan 1.0 recipe. There are some repositories for packages and binaries you can directly install with conan install:
Conan-center: https://bintray.com/conan/conan-center
Bincrafters: https://bintray.com/bincrafters/public-conan
None of them have right now log4cxx. If you need that dependency, the best would be trying to update it to conan 1.0, collaborating with the original author, or with the bincrafters community in https://github.com/bincrafters.
The process to try if the recipe works is:
git clone & cd repo
conan create . user/channel
That will fire the local creation of the package. In the case of that log4cxx repo, it is failing in my case, because of the self.run("sudo apt-get install --yes libapr1-dev libapr1 libaprutil1-dev libaprutil1"), as I am running in Windows. The recipe seems to be prepared only for Linux/Apt. There are now a dedicated recipe method system_requirements() that should contain the installation of system level packages, instead of the build() method.

I would like to upgrade my PCL to a newer version to fix a problem I have with QHull related to this issue.
I'm on ubuntu so I installed PCL with sudo apt install libpcl-dev but I can only get the version 1.10.1. How can I install a newer version ?
The problem is apparently fixed by this commit. It's in the tag 1.12.1.
I know that in theory I can use cmake and build my own PCL but from what I saw with the apt install, there is a huge amount of dependencies + I will also need this particular Qhull version that they mention in the issue and commit... I'm not sure I can make this work without the package manager. Any leads on this problem ?
Thanks !
In its simplest form, building and installing PCL goes likes this:
Clone the GitHub repo and cd inside it
Optionally checkout a git tag or stay on the master branch (default)
mkdir build && cd build
Run cmake with cmake ..
Build and install with make -j2 && sudo make install
For more information, see here: https://pcl.readthedocs.io/projects/tutorials/en/master/compiling_pcl_posix.html
When you previously had libpcl-dev installed, you can remove that package without (auto-)removing the dependencies, then you should have most if not all dependencies required for building from source already installed.
You didn't say which Ubuntu version you use, but judging from the version of libpcl-dev, I assume it is focal (20.04). The Qhull version installed there is fine, it already has a reentrant interface.
I am trying to install apache-airflow (pip install apache-airflow) and I have to use a custom nexus to get it from. It is downloaded fine, but after the download it tries to run its setup.py which has got its dependencies to download, it tries to get its dependencies from https://pypi.org/ which is blocked in my environment ( I cant use that). Is there a way to tell it to look for all its dependencies in my nexus rather than https://pypi.org/
Have a look at https://packaging.python.org/guides/hosting-your-own-index/ to setup custom PyPI repository. Once that is setup, pip will use that to download dependencies.
We need to install R-base version 3.5+ on an offline machine running SLES12.3
We have downloaded all the packages from the the SUSE r repo
http://download.opensuse.org/repositories/devel:/languages:/R:/released/openSUSE_12.3/x86_64/
while running zypper install on the packages there are additional dependencies that we are not able to find the relevant packages to download.
These include:
libtcl8.5.so()(64bit)
libgomp.so.l()(64bit)
But we are not able to find the dependency package that include these libraries.
What should be the correct approach for installing these libraries offline? where can we find these libraries?
Is there a better way for offline installing R-base ? we tried to follow the instructions on the cran rstudio page
The files you downloaded don't match the distribution you're running. SUSE Linux Enterprise (SLE) and openSUSE are similar in some ways, but these are really two separate distributions and you can not always mix binaries between the two. To install R on SLE Server 12.3, you should use the repository https://download.opensuse.org/repositories/devel:/languages:/R:/released/SLE_12/.
You can find out these URLs by looking at the right hand-side column at https://build.opensuse.org/project/show/devel:languages:R:released. Look for things called "SLE" there.
Install the Development Tools, according to this answer
zypper install --type pattern Basis-Devel
Download R source and install it
wget http://cran.univ-paris1.fr/src/base/R-3/R-3.5.0.tar.gz
tar zxf R-3.5.0.tar.gz
cd R-3.5.0
./configure --enable-R-shlib
make
make check
make install
Maybe there are still dependencies missing, which need to be installed with zypper (I don't have any Suse to try myself). With this method you have an "empty" R and you will install R packages one by one (with R CMD INSTALL). Maybe not the best answer for your need, but an answer.
As Meteor 0.6.x introduced support of node packages, it is still not clear how to configure dependency to npm package for whole application. Lets say i need to 'require' some node package in the server code. How to make sure this package will be installed after app is deployed somewhere else?
It's easy enough to setup a package.json file in the root of your project.
You can find a cheatsheet here to help you set one up: http://package.json.nodejitsu.com/
Under dependencies you can specify your runtime deps.
They are installed using the $ npm install command or # npm -g install in case you wnat to install them on your system rather than local to the project.
I'm looking for help about making rpm packages.
I just created my first RPM package with rpmbuild.
This package is simple. It has just to copy several config files and one executable.
I cannot install this .rpm because 2 shared librairies used by the executable are required.
These librairies are already installed but they are not linked with another .rpm package because I build them from one of my projects. There are located in the /usr/myproject/lib directory.
I tried to put symbolic links to /lib and /usr/lib, tried also to run a "ldconfig" update from a .conf file which contains the /usr/myproject/lib directory, and tried to update the LD_LIBRARY_PATH env variable without any success.
I know I can ignore dependencies using the -nodeps command line option but I'd like in the next step to create my own yum repository but yum do not allow to install a package if the dependencies are not fulfilled.
I would also prefer to keep the automatic dependency feature of rpmbuild enabled.
Thanks in advance.
Package these 2 libraries in another RPM, then you can install both RPMs in one rpm -i call.
