I have installed Boost 1.55 (+python33), boost-build and boost-jam through Macports on Mac OS X 10.9.
Following the HOWTO (http://www.boost.org/doc/libs/1_55_0b1/libs/python/doc/building.html), I
cd to /opt/local/share/doc/boost/libs/python/example/quickstart and typed in bjam toolset=gcc
--verbose-test test and just bjam and I got the following error message:
/opt/local/share/boost-build/build/project.jam:271: in find-jamfile from module project
error: Unable to load Jamfile.
error: Could not find a Jamfile in directory '../../../..'.
error: Attempted to find it with pattern '[Bb]uild.jam [Jj]amfile.v2 [Jj]amfile [Jj]amfile.jam'.
error: Please consult the documentation at 'http://www.boost.org'.

/opt/local/share/doc/boost/libs/python/example/quickstart/boost-build.jam:8: in module scope from module
Clearly the Macports put the files in some "non-default" locations. For example, the boost-build directory (specified in boost-build.jam) is in /opt/local/share/doc/boost/tools/build/v2. In the file Jamroot:
# Specify the path to the Boost project. If you move this project,
# adjust the path to refer to the Boost root directory.
use-project boost
: ../../../.. ;
Clearly the desired jamefile is not in ../../../.. on Macports installation.
My question is: where is the desired jamefile located in Macports installation of boost? What path should I specify in Jamroot?

I have to use qdiscs in some part of my project. so i was using the below command and got this error. the problem is there is libnl3 package prersent but it is searhing for libnl version.
nl-qdisc-add --dev=veth-host --parent=root --update plug --buffer
Error: Unable to load module "/usr/lib/x86_64-linux-gnu/libnl/cli/qdisc/plug.so": /usr/lib/x86_64-linux-gnu/libnl/cli/qdisc/plug.so: cannot open shared object file: No such file or directory
So I tried this solution mentioned in comments, but its not working. cannot comment on this link due to reputation.
I changed the 4th step to ./configure --prefix=/usr/local --with-pkgconfigdir=/usr/local/lib because of some error it was giving.
It throws this error:
/usr/local/sbin/nl-qdisc-add --dev=veth-host --parent=root plug --limit=32768

I am trying to install qt/5.14.2 with conan.
Using
qt/5.14.2#bincrafters/stable
I receive
ERROR: libpq/11.5: Error in package_info() method, line 211
self.cpp_info.components["pq"].requires.append("zlib::zlib")
AttributeError: 'Component' object has no attribute 'requires'
OK, there is a bug in libpq/11.5
I am trying to downgrade to
libpq/11.4#bincrafters/stable
ERROR: Conflict in qt/5.14.2#bincrafters/stable:
'qt/5.14.2#bincrafters/stable' requires 'zlib/1.2.11' while 'libpq/11.4#bincrafters/stable' requires 'zlib/1.2.11#conan/stable'.
To fix this conflict you need to override the package 'zlib' in your root package.
BTW:
Why is it not enough to require the correct version of the library, and requiring the same repository? (and require two different repositories in two different packages for the same dependence)
OK, I attempted
zlib/1.2.11#bincrafters/stable
WARN: libpq/11.4#bincrafters/stable: requirement zlib/1.2.11#conan/stable overridden by your conanfile to zlib/1.2.11#bincrafters/stable

Finally, I arrived at
libpq/11.4#bincrafters/stable
zlib/1.2.11#conan/stable
qt/5.14.2#bincrafters/stable
After this, it looks like it was oK:

However, the install fails with
CMake was unable to find Qt5, put qmake in your path or set
QTDIR/QT_QMAKE_EXECUTABLE.
The package is downloaded, I see all components in the corresponding subdirectory in my home directory. However, unlike the other components, it is not installed, before CMake attempts to find it.
What do I wrong?
In case of any strange behavior of conan, upgrade! For me, switch 1.24.0 -> 1.28.1 with configs clean up fixed the same problem with libpq/11.5
I am trying to install ros2 env in Mac. I created a conda env for it.
I have installed conda install -c anaconda sphinx and conda install -c conda-forge sphinx-autodoc-typehints.
I got the errors when I ran ros2 run demo_nodes_cpp talker:

Any idea? Thank you in advance
I got it working by linking the newer installed poco version:

i'm trying to lunch bjam as a step to install the boost library, needed to run Cufflinks (RNASeq analysis software).
however, when i run the code:

i get the following error

and I don't really know how to overcome that.
the directory /cygdrive/c/cygdrive/c/Boost/ (and i tried to use only this path but the result is the same) is where i have installed the various files using the code b2 install --prefix=/cygdrive/c/cygdrive/c/Boost/, however, it contains two folders include and lib, lib is empty while include contains --> boost-1_53 --> boost and here there are all the other folders and the .hpp files.
i am using cygdrive on Win 7 if that helps!
thanks :)

Both brew installed python3 and manually compiled python3 with -–enable-loadable-sqlite-extensions fails when import sqlite from python3 shell. Please help!
The module is named sqlite3, not sqlite:
import sqlite3
http://docs.python.org/3/library/sqlite3.html
Update: Now that we've cleared up the module name, the problem being reported:
ImportError: No module named '_sqlite3'
means that your Python instance cannot find the C extension module, _sqlite3.so, that is part of the sqlite3 module in the standard library. Since the file path of the dbapi2.py in the traceback looks reasonable, the issue is probably not a path issue (sys.path). Most likely the _sqlite3 extension module failed to build or link. Check the output from your Python build for errors. OS X 10.8 includes a version of sqlite3 but for security reasons it does not include the optional loadable extensions feature. Your Python build likely included this message:
Failed to build these modules:
_sqlite3
and, earlier, this:
*** WARNING: renaming "_sqlite3" since importing it failed: dlopen(build/lib.macosx-10.8-x86_64-3.3-pydebug/_sqlite3.so, 2): Symbol not found: _sqlite3_enable_load_extension
Referenced from: build/lib.macosx-10.8-x86_64-3.3-pydebug/_sqlite3.so
Expected in: flat namespace
in build/lib.macosx-10.8-x86_64-3.3-pydebug/_sqlite3.so
The solution is to build and install a separate copy of sqlite3 that is built with the loadable extensions feature. If you are using Homebrew, its sqlite recipe with the with-functions option should do that. Then rebuild Python.
Homebrew provides python3 with sqlite3 support and loadable modules.
brew install python3 will do the right thing (and brew sqlite, too).
There was a bug, that probably struck you, but it has been fixed
