I have been trying to install xv6 using the following commands:
sudo apt-get install qemu
sudo apt-get install libc6-dev-i386
tar xzvf xv6-rev11.tar.gz
cd xv6-public
make
make qemu
I get the following error while running make qemu command
qemu-system-i386 -serial mon:stdio -drive file=fs.img,index=1,media=disk,format=raw -drive file=xv6.img,index=0,media=disk,format=raw -smp 2 -m 512
make: qemu-system-i386: Command not found
make: *** [Makefile:225: qemu] Error 127
As suggested at various places, I have un-commented line 54 QEMU = qemu-system-i386 in the makefile before executing make qemu
Please help me fix the error. Thanks in advance ...
You need to install the package containing qemu-system-i386.
After a little search on https://packages.ubuntu.com, you can find the right package: qemu-system-x86.
To install the missing package, type
sudo apt install qemu-system-x86

I am trying to start using TPM on Linux, on my Raspberry Pi to be accurate, and the easiest would be to use swtpm to get used to commands and system, before using a TPM chip. I've tried the way presented on https://github.com/stefanberger/swtpm/wiki#compile-on-ubuntu-2104, but I got the error "Unable to locate libtpms-dev".
Then I looked for a way to install libtpms, and found this one solution. But after getting those both, I still couldn't run this command :
sudo swtpm socket --tpmstate dir=/home/ludovic.peyter/swtpm --tpm2 --server type=tcp,port=2321 --ctrl type=tcp,port=2322 --flags not-need-init,startup-clear
All I get is the following error :
swtpm: SWTPM_NVRAM_Lock_Dir: Could not open lockfile: No such file or directory
and
swtpm: Error: Could not initialize libtpms.
And here am I stuck, finding nothing to help me with this problem, or even an other way to avoid it.
Thanks for reading.
I have a complete solution, built with many different solutions and my own tests.
sudo apt -y install dpkg-dev debhelper libssl-dev libtool net-tools libfuse-dev libglib2.0-dev libgmp-dev expect libtasn1-dev socat python3-twisted gnutls-dev gnutls-bin libjson-glib-dev gawk git python3-setuptools softhsm2 libseccomp-dev automake autoconf libtool gcc build-essential libssl-dev dh-exec pkg-config dh-autoreconf libtool-bin tpm2-tools libtss0 libtss2-dev
Then make a new directory for more comfort, and step into it.
Clone git repository for libtpms :
git clone https://github.com/stefanberger/libtpms.git
Move to the generated libtpms directory and run these commands :
./autogen.sh -–with-openssl
make dist
dpkg-buildpackage -us -uc -j4
Then, as asked at the end of the last running command, run :
libtool --finish /usr/lib/aarch64-linux-gnu/
The directory could be different, so pay attention to the warning at the end of dpkg command.
And to finish the installation of libtpms :
sudo apt install ../libtpms*.deb
Now get back to the previous directory and clone swtpm git repository :
git clone https://github.com/stefanberger/swtpm.git
Now run this command :
dpkg-buildpackage -us -uc -j4
And the command asked by the previous running command :
libtool --finish /usr/lib/aarch64-linux-gnu/swtpm
The directory could be different, so pay attention to the warning at the end of dpkg command.
Now finish the installation with this :
sudo apt install ../swtpm*.deb
Everithing you need is installed. Now you need to modify the file ~/.profile or ~/.bash_profile to add this line :
export TPM2TOOLS_TCTI="swtpm:port=2321"
And now, everytime you need your swtpm, open two terminals, and in one of them run :
swtpm socket --tpmstate dir=<swtpm_path> --tpm2 --server type=tcp,port=2321 --ctrl type=tcp,port=2322 --flags not-need-init,startup-clear
In the other terminal, as long as the above command runs, you can run all your TPM commands.
Have you checked that the tpmstate directory exists? A mkdir /home/ludovic.peyter/swtpm2 could fix it for you.
I'm using a RaspberryPi Zero W with Raspbian 4.9.80+ and I'm trying to install LTTng-modules-2.8 but when I type these commands
wget http://lttng.org/files/lttng-modules/lttng-modules-latest-
2.8.tar.bz2 &&
tar -xf lttng-modules-latest-2.8.tar.bz2 &&
cd lttng-modules-2.8.* &&
make &&
sudo make modules_install &&
sudo depmod -a
I receive this (after typing the command "make"):
make -C /lib/modules/4.9.80+/build M=/home/pi/lttng-modules-2.8.7
CONFIG_LTTNG=m
CONFIG_LTTNG_CLOCK_PLUGIN_TEST=m modules
make[1]: *** /lib/modules/4.9.80+/build: No such file or directory. Stop.
Makefile:110: receipe for target 'modules' failed
make: *** [modules] Error 2
I downloaded the modules correctly but it seems that they are not there; how can I solve this problem?
Thanks, Ivan.
You need the kernel headers to build modules, according to raspbian's documentation they are provided by the raspberrypi-kernel-headers, you can install it with this command :
sudo apt-get install raspberrypi-kernel-headers
And then run the make commands.
I want to install MarkLogic 9 on my ubuntu machine. I tried following steps from this doc
sudo apt-get install alien
sudo alien --to-deb --verbose MarkLogic-9.0-3.1.x86_64.rpm
sudo dpkg -i marklogic_4.1-6_amd64.deb
sudo /etc/init.d/MarkLogic start
But when I tried the second one I got an error like this:
iama#learner:~$ sudo alien --to-deb --verbose MarkLogic-9.0-3.1.x86_64.rpmFile "MarkLogic-9.0-3.1.x86_64.rpm" not found.
I don't know how to proceed further. I just wanted to confirm, is there any official documentation to install MarkLogic 9 in ubuntu?
The error is "File Not Found"
Make sure the rpm file exists in the current directory with read privileges with the name given.
Make sure sudo is not changing to another directory.
To be certain, use an absolute file path.
Then, test with sudo ls -l file..
I am trying to install haproxy on my centos 6.5 server. I am using the command
yum install haproxy
This command installs a version 1.4.x. I have also looked at the following links, but could not get it to work
http://virtuallyhyper.com/2013/05/configure-haproxy-to-load-balance-sites-with-ssl/
http://blog.haproxy.com/2012/09/10/how-to-get-ssl-with-haproxy-getting-rid-of-stunnel-stud-nginx-or-pound/
https://github.com/bluerail/haproxy-centos
how do i install it?
You can build the RPM as follows:
mkdir -p rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
sudo yum -y install pcre-devel openssl-devel
cd rpmbuild/SOURCES
curl -L -O http://www.haproxy.org/download/1.5/src/haproxy-1.5.3.tar.gz
tar zxf haproxy-1.5.3.tar.gz
cd ..
cp -p SOURCES/haproxy-1.5.3/examples/haproxy.spec SPECS/haproxy153.spec
sed -i 's/Release: .*/Release: %{?_release:%{_release}}%{!?_release:1}/' SPECS/haproxy153.spec
sed -i 's/USE_PCRE=1 /USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 /' SPECS/haproxy153.spec
rpmbuild --define "_topdir `pwd`" --define "_release 2" -bb SPECS/haproxy153.spec
(I use a local directory and set the release number otherwise it is the same as http://qiita.com/uemura/items/e822c1ed505b9fe0208f)
Install
scp RPMS/x86_64/haproxy-1.5.3-2.x86_64.rpm root#somewhere:~/
somewhere# yum localinstall ~/haproxy-1.5.3-2.x86_64.rpm
You could install from source using one of these tar bundles:
http://www.haproxy.org/download/1.5/src/
You will probably need to install the following bundles to compile from source:
yum openssl-devel pcre-devel make gcc
Here's also a script which I presume would work on your environment
I went through fair amount of google search to install ack-grep on CentOS but I didn't find anything help. I also looked for the source codes but couldn't find it neither. Does anyone know how to install it on the OS?
Thanks a lot.
Could be essentially the same as https://stackoverflow.com/a/23155007/35946 but on CentOS 6.7 the answer is:
# yum install epel-release
# yum install ack
if you don't have the root permission, you can do as follows:
$ curl https://beyondgrep.com/ack-2.22-single-file > ~/bin/ack && chmod 0755 !#:3
or you can change to root user:
$ sudo su
# curl https://beyondgrep.com/ack-2.22-single-file > /bin/ack && chmod 0755 !#:3
You can get it from the EPEL software repository.
From the EPEL FAQ:
For EL5:
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm'
...
su -c 'yum install ack'
For EL6:
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm'
...
su -c 'yum install ack'
Go to Beyond Grep and look at the section titled
Install The ack executeable
curl http://beyondgrep.com/ack-2.14-single-file > ~/bin/ack && chmod 0755 !#:3
And replace ack.2.14 with the current version of ack.
You may need to create the directory mkdir ~/bin/ first. You may
also need to modify ~/.bashrc to include this new path E.G.:
PATH=$PATH:$HOME/bin
Then reload ~/.bashrc
source ~/.bashrc
Test the installation by running ack:
rpm -qa | ack s
This should display any installed packages containing the letter s. (some linux distributions may use ack-grep as the command.
How did you try installing it? Are you using yum? The package is probably not called "ack-grep", but just "ack".
The name "ack-grep" is a Debian-specific thing because there was already a package called "ack", so they called it "ack-grep" instead. That was years ago and now they're dropping the original "ack" package and renaming "ack-grep" to "ack".
For RedHat Enterprise just do sudo yum install ack
