I have just upgraded my server to ubuntu 20.04 LTS.
I am now trying to various different code packages on it and receiving errors relating to the boost installation.
Rather than building from source, I have installed boost 1.71.0 using apt:
sudo apt-get install libboost-all-dev
However, when I try and compile code I am getting errors such as:
fatal error: boost/algorithm/string/trim.hpp: No such file or directory
15 | #include <boost/algorithm/string/trim.hpp>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
boost/log/sinks/text_ostream_backend.hpp: No such file or directory
6 | #include <boost/log/sinks/text_ostream_backend.hpp>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I have spent the last 3 hours trying to find those hpp files with no success. There is nothing in:
/usr/local/include/
/usr/local/lib/
/usr/lib/
/usr/include/boost *doesn't exist*
Any idea what could be wrong?
I'm trying to avoid installing boost from source, rather than the Ubuntu package but do I have to?
Managed to resolve the issue.
Turns out that because I had a previous boost installation from a manual installation (before I upgraded to 20.04 LTS) and had deleted those files manually, further re-installs via apt were not recreating the files in usr/include/, due to other packages relating to boost still installed in the system.
The recovery was to run apt list --installed '*boost*' and then uninstall any of those linked packages.
After doing that running sudo apt install libboost-all-dev recreated the /usr/include/boost directory with all the header files.
This process was listed in the answer on: https://askubuntu.com/questions/1161393/i-deleted-usr-include-boost-installing-libboost-all-dev-wont-bring-headers-ba
I got this error when I executed g++ mycode.cpp, and this .cpp file include a line #include<openssl/rsa.h>. Now, I know the error's reason, and I have tow plan to resolve it:
I can add the openssl path to /etc/profile,
or I also can copy openssl folder to /usr/include, so I did the first plan, like this:
CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/mylib
export CPLUS_INCLUDE_PATH
(my openssl folder's path is /mylib/openssl)
and I got this error again.
Then I try second plan, and it passed complie,(like this /usr/include/openssl).
Now, my problem is,
why the header ("openssl/rsa.h") can be found under /usr/include/ but can not be found under /mylib/, even I had add the path(/mylib) to /etc/profile?
To install OpenSSL on Debian, Ubuntu, or other derivative versions:
$ sudo apt-get install libssl-dev
To install the OpenSSL development kit on Fedora, CentOS, or RHEL:
$ sudo yum install openssl-devel
After installation, try to recompile the program.
Try to reinstall the library using the apt-get
sudo apt-get install libssl-dev
After downloading and untar the file "boost_1_56_0.tar.gz", I have installed Boost C++ library version "boost_1_56_0" in CentOS Linux.
I have run the following commands to install:
sudo ./bootstrap.sh --prefix=/usr/local
sudo ./b2 install.
I also added two paths to the PATH variable:
export PATH=$PATH:/usr/local/include/:/usr/local/lib/
It has been successfully installed. However when I checked the version it showed different version:
$ cat /usr/include/boost/version.hpp | grep "BOOST_LIB_VERSION"
#define BOOST_LIB_VERSION "1_33_1"
I have tried to install boost_1_55_0 as well in another folder but unfortunately still it shows version 1_33_1.
Can anyone here tell me how I can fix this issue?
Because of this issue, I am unable to configure Graph_tool; it shows following error:
checking for boostlib >= 1.53.0... configure: error: We could not detect the boost libraries (version 1.53 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in . See http://randspringer.de/boost for more documentation>
Your bootstrap path is /usr/local. Make sure your BOOST_ROOT points to your bootstrapped folder, not the installed 1.33 version.
I am trying to compile my own c++/qt5.2 app which uses yaml-cpp under Ubuntu 14.04.
While issuing the make command I get the following error
fatal error: yaml-cpp/yaml.h: No such file or directory
on the line:
#include <yaml-cpp/yaml.h>
How can I fix this?
You need to install the yaml-cpp library.
Under Ubuntu 14.04 you can do this by simply running one of the following commands in a terminal window (depending one the API you use):
sudo apt-get install libyaml-cpp-dev
or
sudo apt-get install libyaml-cpp0.3-dev
See the yaml-cpp project page for other operating systems and differences between old (0.3) and new API.
I'm trying to build some code on Ubuntu 10.04 LTS that uses OpenSSL 1.0.0. When I run make, it invokes g++ with the "-lssl" option. The source includes:
#include <openssl/bio.h>
#include <openssl/buffer.h>
#include <openssl/des.h>
#include <openssl/evp.h>
#include <openssl/pem.h>
#include <openssl/rsa.h>
I ran:
$ sudo apt-get install openssl
Reading package lists... Done
Building dependency tree
Reading state information... Done
openssl is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
But I guess the openssl package doesn't include the library. I get these errors on make:
foo.cpp:21:25: error: openssl/bio.h: No such file or directory
foo.cpp:22:28: error: openssl/buffer.h: No such file or directory
foo.cpp:23:25: error: openssl/des.h: No such file or directory
foo.cpp:24:25: error: openssl/evp.h: No such file or directory
foo.cpp:25:25: error: openssl/pem.h: No such file or directory
foo.cpp:26:25: error: openssl/rsa.h: No such file or directory
How do I install the OpenSSL C++ library on Ubuntu 10.04 LTS?
I did a man g++ and (under "Options for Linking") for the -l option it states: " The linker searches a standard list of directories for the library..." and "The directories searched include several standard system directories..." What are those standard system directories?
You want to install the development package, which is libssl-dev:
sudo apt-get install libssl-dev
Run:
apt-get install libssl-dev
All of these answers are very outdated and from when the package was still being developed. You can now just use the "normal" command listed below:
sudo apt install openssl
Edit: OP's question is poorly worded... after all, OpenSSL is a library itself, so I read his question too quickly before answering. The command above installs "normal" OpenSSL.
Toward the bottom of his question he mentions that make fails, suggesting he is compiling the package manually. And yes, even if you download the TAR ball, it will include all of the openssl and libssl files, which you can then make from.
What OP is really asking for is the OpenSSL Development Library, in which case you can first install OpenSSL using the above command, and then run this afterwards:
sudo apt install libssl-dev
More info: https://linuxtect.com/how-to-install-openssl-libraries-on-ubuntu-debian-mint/
I found a detailed solution here: Install OpenSSL Manually On Linux
From the blog post...:
Steps to download, compile, and install are as follows (I'm installing version 1.0.1g below; please replace "1.0.1g" with your version number):
Step – 1 : Downloading OpenSSL:
Run the command as below :
$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz
Also, download the MD5 hash to verify the integrity of the downloaded file for just varifacation purpose. In the same folder where you have downloaded the OpenSSL file from the website :
$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz.md5
$ md5sum openssl-1.0.1g.tar.gz
$ cat openssl-1.0.1g.tar.gz.md5
Step – 2 : Extract files from the downloaded package:
$ tar -xvzf openssl-1.0.1g.tar.gz
Now, enter the directory where the package is extracted like here is openssl-1.0.1g
$ cd openssl-1.0.1g
Step – 3 : Configuration OpenSSL
Run below command with optional condition to set prefix and directory where you want to copy files and folder.
$ ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl
You can replace “/usr/local/openssl” with the directory path where you want to copy the files and folders. But make sure while doing this steps check for any error message on terminal.
Step – 4 : Compiling OpenSSL
To compile openssl you will need to run 2 command : make, make install as below :
$ make
Note: check for any error message for verification purpose.
Step -5 : Installing OpenSSL:
$ sudo make install
Or without sudo,
$ make install
That’s it. OpenSSL has been successfully installed. You can run the version command to see if it worked or not as below :
$ /usr/local/openssl/bin/openssl version
OpenSSL 1.0.1g 7 Apr 2014
How could I have figured that out for
myself (other than asking this
question here)? Can I somehow tell
apt-get to list all packages, and grep
for ssl? Or do I need to know the
"lib*-dev" naming convention?
If you're linking with -lfoo then the library is likely libfoo.so. The library itself is probably part of the libfoo package, and the headers are in the libfoo-dev package as you've discovered.
Some people use the GUI "synaptic" app (sudo synaptic) to (locate and) install packages, but I prefer to use the command line. One thing that makes it easier to find the right package from the command line is the fact that apt-get supports bash completion.
Try typing sudo apt-get install libssl and then hit tab to see a list of matching package names (which can help when you need to select the correct version of a package that has multiple versions or other variations available).
Bash completion is actually very useful... for example, you can also get a list of commands that apt-get supports by typing sudo apt-get and then hitting tab.
Another way to install openssl library from source code on Ubuntu, follows steps below, here WORKDIR is your working directory:
sudo apt-get install pkg-config
cd WORKDIR
git clone https://github.com/openssl/openssl.git
cd openssl
./config
make
sudo make install
# Open file /etc/ld.so.conf, add a new line: "/usr/local/lib" at EOF
sudo ldconfig
You want the openssl-devel package.
At least I think it's -devel on Ubuntu. Might be -dev. It's one of the two.
As a general rule, when on Debian or Ubuntu and you're missing a development file (or any other file for that matter), use apt-file to figure out which package provides that file:
~ apt-file search openssl/bio.h
android-libboringssl-dev: /usr/include/android/openssl/bio.h
libssl-dev: /usr/include/openssl/bio.h
libwolfssl-dev: /usr/include/cyassl/openssl/bio.h
libwolfssl-dev: /usr/include/wolfssl/openssl/bio.h
A quick glance at each of the packages that are returned by the command, using apt show will tell you which among the packages is the one you're looking for:
~ apt show libssl-dev

Go to the official website and download the source code for the version you need
Then unzip the update package and execute the following command
./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl -Wl,-rpath,/usr/local/ssl/lib shared
Because the default is to generate only static libraries, if you want dynamic libraries, add the "shared" option
make && make install
sudo apt-get install libcurl4-openssl-dev
