I am installing kaldi in ubuntu 18.04. python2.7 is one of the dependencies to install kaldi. I have installed python2.7 by sudo apt-get install pytho2.7. Then to check the prerequisites run
extras/check_dependencies.sh. The result showing - "python2.7 is installed, but the python2 binary does not exit. Creating a symlink and adding this to tools/env.sh"
What is the next step to do?
You should add symlink to python2.7 binary:
ln -fs /usr/bin/python2.7 $(KALDI_ROOT)/tools/python/python2
Where $(KALDI_ROOT) is a root directory of Kaldi source code
i just input 'ln -fs /usr/bin/python2.7'

I removed by mistake /usr/lib64/libpython2.7.so, and as a consequence, yum does not work.
So I'm trying to reinstall python2.7.18 (which is the version that I currently have) from source, but in compilation I get that some modules are missing
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _curses _curses_panel
_ssl _tkinter bsddb185
bz2 dl imageop
readline sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
But:
yum doesn't work, pip2 also doesn't work, setuptools for python setup.py install is not found...
And all solutions I'm finding involve some of those, so I'm getting into some circular problem here.
I looked for the *.rpm for python 2.7.18 for CentOS 7, in the hope I could just install it with rpm and solve the issue, but I couldn't find it.
Any idea?
Found a solution, starting from here.
After manually rm-ing all the /usr/**/*python2.7* files (probably just the libpython2.7.so* and the python2.7 executables would be enough), from
http://mirror.centos.org/centos/7/os/x86_64/Packages/, I downloaded

As the title said I can't install that specific version of g++ in my current ubuntu (20.04).
I have been trying the usual things as: sudo apt install g++- (and displaying all posibilities but there where only versions from 8 to 10). Same happend looking for gcc possibilities.
Also tried this: gist.github.com/application2000/73fd6f4bf1be6600a2cf9f56315a2d91 (same problem)
And after looking for a while I gave up in my research and ended up here. Hope someone with more wisdom than me can give my a hand with this.
These steps should work:
sudo dpkg --add-architecture i386
sudo apt update
sudo apt upgrade
sudo apt-get install gcc-multilib libstdc++6:i386
wget https://ftp.gnu.org/gnu/gcc/gcc-4.8.5/gcc-4.8.5.tar.bz2 --no-check-certificate
tar xf gcc-4.8.5.tar.bz2
# cd gcc-4.8.5
# ./contrib/download_prerequisites
# cd ..
sed -i -e 's/__attribute__/\/\/__attribute__/g' gcc-4.8.5/gcc/cp/cfns.h
sed -i 's/struct ucontext/ucontext_t/g' gcc-4.8.5/libgcc/config/i386/linux-unwind.h
mkdir xgcc-4.8.5
pushd xgcc-4.8.5
$PWD/../gcc-4.8.5/configure --enable-languages=c,c++ --prefix=/usr --enable-shared --enable-plugin --program-suffix=-4.8.5
make MAKEINFO="makeinfo --force" -j
sudo make install -j
Note that you have to uncomment the .../download_prerequisites on some platform. For me it worked without on Centos 7 or Ubuntu 20 with the mandatory packages installed:
Ubuntu/Debian:
sudo apt install make wget git gcc g++ lhasa libgmp-dev libmpfr-dev libmpc-dev flex bison gettext texinfo ncurses-dev autoconf rsync
Centos:
sudo yum install wget gcc gcc-c++ python git perl-Pod-Simple gperf patch autoconf automake make makedepend bison flex ncurses-devel gmp-devel mpfr-devel libmpc-devel gettext-devel texinfo
Few seconds later (/giggles) gcc-4.8.5 is installed and available.
Notes:
if you don't have the resources to run make -j omit -j or use -j4 (or a different number which is adequate for your system)
your milage may vary and you may need to install further i386 packages
Since I can't comment I will add to #bebbo solution that on an Ubuntu 20.04 I had to add to his steps patching the following patches:
Add an include to signal.h to libsanitizer/asan/asan_linux.cc
https://patchwork.ozlabs.org/project/gcc/patch/6824253.3U2boEivI2#devpool21/
change a line in libsanitizer/tsan/tsan_platform_linux.cc
as shown. line number may not be the one stated in the patch so search for the line that was changed. There is no need to apply the patch to the other files
https://git.pantherx.org/mirror/guix/commit/0b93d04ac537d6413999349ebe7cdcb1e961700e
Adding to kpeace's answer...
sed -i '/#include <pthread.h>/a #include <signal.h>' path_to_gcc4.8.5src/libsanitizer/asan/asan_linux.cc
sed -i 's/__res_state \\*statp = (__res_state\\*)state\\;/struct __res_state \\*statp = (struct __res_state\\*)state\\;/g' path_to_gcc4.8.5src/libsanitizer/tsan/tsan_platform_linux.cc
Just adding a couple of sed lines to patch them inline.
Also, I've been writing some Ruby scripts to install some software (for fun of course.) I've recently successfully compiled gcc-4.8.5 under LinuxMint 20.1 (Ubuntu 20.04 based, compiler is the system gcc: 9.3.0, installed with sudo apt install build-essential) with this script. Also, I've installed all the packages that Bebbo suggested, including gcc-multilib and libstdc++6:i386 before running this script. Check up InstGcc4 class at the bottom of the code.
install_gcc.rb
They might end up to be 'un-installable' state a few months later. But at least gcc-4.8.5 works now.
ps. I've started to compile this old gcc due to CUDA... My hardware is a decade old GeForce 9600/9400 (yeah 2008 MBP) and CUDA 6.5 was the best option for that machine.
pps. Anyway, strange thing is, I had to give out '-std=gnu++11' for CXXFLAGS to avoid errors.
Hello every one i need to deploy linux(centos) c++ project with make file or script. By one makefile or script install dependency and project executable binary.
my dependency applications libboost-devel,gcc-g++ and pcre. my excuteble binary file is run_excute
Yip sure - put the below commands into a file. At the top of the file add:
#!/bin/bash
Save the file - lets say you call it install; on the command line type:
chmod +x ./install
Then to build and install your program type:
sudo ./install
Alternatively, if you've got some time on your hands:
http://www.rpm.org/max-rpm/ch-rpm-build.html
As an example the basic rpm build process for fedora is:
Step 1: setup your machine to do packaging:
dnf install #development-tools fedora-packager rpmdevtools
rpmdev-setuptree
Step 2: source and Makefile
Place these in ~/rpmbuild/SOURCES
Step 3: Create a spec file
In ~/rpmbuild/SPECS create file called myname.spec. It should contain something like:
Summary: My program description
Name: myname
Version: 0.0.0
Release: 0
License: GPLv2
Group: Applications/Databases
Source: https://xyz.tar.gz
URL: http://myurl
BuildRequires: libicu-devel
BuildRequires: pcre-devel
%description
A couple of lines describing the package
%prep
%setup -q
%build
cd %{myname}/source
make %{?_smp_mflags}
%install
%make_install
%files
%{_bindir}/*
%changelog
* Tue Nov 10 2015 Yours Truly <me#somewhere.com> - 0.0.0-0
- Some change comments
Step 4: create the source and binary rpm
cd ~/rpmbuild/SPECS
rpmbuild -ba myname.spec
Step 5: use the rpm
cd ~/rpmbuild/RPMS/x86_64
rpm -Uvh ./myprogram-version-release.a.whole.lot.of.stuff.rpm
To install the dependencies use yum, so:
sudo yum install libboost-devel
sudo yum group install "Development Tools"
sudo yum install pcre-devel
To build the application, move to the directory with the makefile in it and do:
make
sudo make install
Finally to run the application
./run_excute
or if your lucky
run_excute
will work.
I am not a Linux pro, but I have a task to modify KDE app "dolphin" for home using (modify address bar navigation mechanism). I think, that it would easy, but still have no understanding how to do this. Days of tries led me to the solution, that I should not build dolphin from dolphin repository (git://anongit.kde.org/dolphin), but from kde-baseapps repo:
sudo apt-get update
sudo apt-get install git-core build-essential libkactivities-dev
sudo apt-get build-dep dolphin
git clone git://anongit.kde.org/kde-baseapps && cd kde-baseapps && mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
make -j3
cd dolphin/src/
./dolphin4
Next I think, that I can find source code in "kde-baseapps" folder, but it references to "/usr/include" *.h-files, that references to corresponding *.cpp-files in "kdelibs" package.
That's right, that I should download "kdelibs" sources, modify them and build? That is right way to resolve task or exists a better way to do this?
Yeah, exists a better solution. kdelibs compilation isn't necessary, it is possible to modify only dolphin source code by this bash commands (from ~ dir):
mkdir src
cd src
sudo apt-get update
sudo apt-get build-dep kde-baseapps
apt-get source kde-baseapps
cd kde-baseapps-4.13.3/dolphin/src/
patch < ~/your.patch
cd ../..
mkdir build
cd build
cmake ..
make
sudo make install
I am building a python package, and I want to distribute it via rpm using python setup.py bdist_rpm. However, I am including a configuration file, and I want any changes in there to remain if I ever upgrade the RPM on the machine it's installed on. Is there anyway to set a flag in the setup.py script or command that I don't want the RPM to replace the configuration file in case of upgrades? I'm on Python 2.7. Thanks!
python setup.py bdist_rpm --spec-only
This will create dist/*.spec, manually edit it. Especially change:
%install
python setup.py install --single-version-externally-managed -O1 --root=$RPM_BUILD_ROOT --record=INSTALLED_FILES
%files -f INSTALLED_FILES
to:
%install
python setup.py install --single-version-externally-managed -O1 --root=$RPM_BUILD_ROOT
%files
%{python_sitelib}/*
%config(noreplace) %{_sysconfdir}/yourconfig.conf
Note: you may add more lines to %files section, it depends what you put in buildroot. If you miss something rpmbuild from next step will report it as error.
Then you can build the SRPM using
rpmbuild -bs dist/*.spec
