I installed QCacheGrind with homebrew successfully:
brew install qcachegrind
When I open QCacheGrind app on the tab "Call Graph" I am getting the error:
No graph available because the layouting process failed. Try to run the following command did not work:
'dot -Tplain'
Please check that 'dot' is installed (package graphViz)
Graphviz is installed but doesn't work.
The workaround doesn't work anymore due to System Integration Protection.
sudo ln -s /usr/local/bin/dot /usr/bin/dot
So is there any workaround to get graphs visible in QCacheGrind?

I am trying to install the lustre clients on Unbuntu 20.04 nodes I have in GCP. Im using linux kernel version 5.15.0-1021-gcp.
I'm trying to install the client with the following code:
cd /home/apps/
mkdir lustre
git clone git://git.whamcloud.com/fs/lustre-release.git
cd lustre-release
git checkout 2.15.0
sh autogen.sh
./configure --prefix=/home/apps/lustre --disable-server --enable-client ## doesnt run! Fails at ./configures with error message "error: Run make config in /lib/modules/5.15.0-1021-gcp/build"
make debs
The configure step fails with an error about running make config in /lib/modules/5.15.0-1021-gcp/build. I tried running make config in /lib/modules/5.15.0-1021-gcp/build but was asked to input some values that I was unsure of.
I also tried downloading the deb package of the client software at
https://downloads.whamcloud.com/public/lustre/lustre-2.15.0/ubuntu2004/client/lustre-client-modules-5.4.0-96-generic_2.15.0-1_amd64.deb. However this is for the wrong linux kernel and I'm not sure what env variables need to be set for this package.
Anyone know how to install the client modules for lustre on Ubuntu?
You need to have the kernel sources or kernel-devel package that exactly match the kernel that you are installing on. This should also include the .config file that describes all of the options used when building your kernel.
Alternately, you could try a pre-built package, but it isn't clear if this will install on your kernel or not.

An existing or new project with RubyMotion gives the following error
dlopen(/Applications/Xcode.app/Contents/Developer/../Frameworks/libswiftCore.dylib, 2): image not found and simulator does not open
System details
- Mojave
- Xcode 11.1
- Latest public Rubymotion from the website
Launch Xcode up and accept any terms and let it download any tools it thinks it needs to start up
run sudo xcodebuild -license
run sudo xcode-select --install && sudo xcode-select --reset
make sure you're all up to date (I don't know if the installer does this already, but it doesn't hurt)
sudo motion update
motion repo
Then for above error:

Background:
I created a sandbox VM with VirtualBox on my macOS. It correctly spins up a VM (with CentOS7 running on it) on which I can access to.
Inside this sandbox vm, I want to spin up several vms in order to test Ansible Playbooks with Kitchen CI & Vagrant, thus I installed VirtualBox by downloading it from the following link: https://download.virtualbox.org/virtualbox/5.2.8/VirtualBox-5.2-5.2.8_121009_el7-1.x86_64.rpm
After the installation I executed the command:
[david#vmkitchen-env ansible-test]# VBoxManage --version
It returned:
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (3.10.0-693.2.1.el7.x86_64) or it
failed to load. Please recompile the kernel module and install it
by
sudo /sbin/vboxconfig
You will not be able to start VMs until this problem is fixed.
5.2.8r121009
I installed the Development tools, but I keep getting the same issue.
I don't think I need to recompile any kernel module. Any idea?
Thanks in advance for your help.
So, after searching on the internet, and not just on the VirtualBox website, I found the solution, and I was right: I did not need to compile any module.
The following is the reference to the CentOS wiki page:
https://wiki.centos.org/HowTos/Virtualization/VirtualBox
In a few words, I had to install dkms and kernel-devel packages. In order to do so, I needed to install EPEL repository; but personally I prefer to install and enable the IUS repository.
The following are the set of commands that worked for me:
yum groupinstall "Development tools"
yum install https://centos7.iuscommunity.org/ius-release.rpm
yum install dkms
yum install kernel-devel
reboot
After the machine had rebooted, I was able to get VirtualBox working fine.
I verified by the command line:
[david#vmkitchen-env ansible-test]# VBoxManage --version
And it returned the correct value:
5.2.8r121009
Below steps fixed the issue for me.
1.sudo /sbin/vboxconfig
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is currently not set up to build kernel modules.
Please install the Linux kernel "header" files matching the current kernel
for adding new hardware support to the system.
The distribution packages containing the headers are probably:
kernel-devel kernel-devel-3.10.0-957.10.1.el7.x86_64
2.This website has the kernel module - website
wget https://linuxsoft.cern.ch/cern/centos/7/updates/x86_64/Packages/kernel-devel-3.10.0-957.10.1.el7.x86_64.rpm
4.yum localinstall kernel-devel-3.10.0-957.10.1.el7.x86_64.rpm -y
5.sudo /sbin/vboxconfig
Issue resolved
On Fedora 36, I only had to run
sudo /sbin/vboxconfig
I try to install the package "data.table" (and "aws.s3)" via Rstudio Server on an Amazon Linux instance following this guide:
http://stanke.co/category/r/
Unfortunately, I get the following error message. I really don't know what else to do.
Can anybody help? I installed devtools and I am able to install other packages such as xml2, devtools and deplyr.
I had the same issue on AWS and already fixed.
You need first install gcc64 and openmp shared support library.
sudo yum install gcc64
sudo yum install libgomp
Then under your user home create an .R folder with a Makevars file in it, with the following content (it will tell to R which compiler to use):
CC = /usr/bin/gcc64
CXX = /usr/bin/g++
SHLIB_OPENMP_CFLAGS = -fopenmp
I hope it's working for you as well ...
You need to install dmlc-core.
This link will provide more information:
A common bricks library for building scalable and portable distributed machine learning
based on https://github.com/RcppCore/RcppArmadillo/issues/200, I think this issue is due to a g++ compatability issue. It might also explain why when I installed devtools it kept giving me [-Wdeprecated-declarations]
so run:
sudo yum remove gcc72-c++.x86_64 libgcc72.x86_64
yum install R-devel
Then you should be able to run the installation command.
I installed protocol-buffers in C++ in my Ubuntu 14.04 LTS PC by following instructions provided at official GitHub page here.
There was no error reported during installation. However, I would like to verify the installation hence I run protoc --version but it returned following error message:
The program 'protoc' is currently not installed. You can install it by typing:
sudo apt-get install protobuf-compiler
I am wondering why it is behaving like this? Am I missing something obvious?
I want to generate CPP and header file for my protocol buffers message file as well.
