PyCaffe build fails, lboost_python not found

I am on MacOS 10.13.3 (17D47) with Python 2.7.14. I am in the process of building caffe w/ python. The project is CPU only. I am able to build caffe through make run test however, after attempting make pycaffe I get an error. This is the result:
touch python/caffe/proto/__init__.py
CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp

ld: library not found for -lboost_python
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [python/caffe/_caffe.so] Error 1
I have a Makefile.config that calls out boost-python from the brew install set as:
# Whatever else you find you need goes here.
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/local/Cellar/boost-python/1.67.0/lib
My two initial questions are:
1)Am I not allowed to link to the boost library using the system python? 2)What is the correct way to tell make to grab boost-python?

I was actually having the same problem and couldn't find any answers for days. However, I found this question: Build caffe with Python ( cannot find -lboost_python3 ) .
That question is for python3, but I'm using python2.7 . Basically, I went into the Makefile (not Makefile.config), searched for boost_python, and changed it to boost_python27 . I did the following steps:
vim Makefile
use vim command :?boost_python (there should only be 1 occurrence)
changed PYTHON_LIBRARIES ?= boost_python python2.7
to PYTHON_LIBRARIES ?= boost_python27 python2.7
ran the command sudo make pycaffe
I hope this helps you!

Goto Makefile (and not the .config file) and change the name of the ld library to python27.

Unable to build SWIG.exe using MinGw

I am trying to install 'pocketsphinx' module in python which requires swig.exe. After a lot of searching I followed the steps mentioned in the swig site(http://www.swig.org/Doc3.0/Windows.html#Windows_swig_exe) to build an exe. But I am stuck at the last 2 steps.
When './autogen.sh' is executed, I get the following error message although the file 'aclocal' is present in the '/mingw/bin' directory.
vinay#DESKTOP-7LB2J5M /usr/src/swig
$ ./autogen.sh
+ test -d Tools/config
+ aclocal -I Tools/config
./autogen.sh: /mingw/bin/aclocal: No such file or directory
I renamed c:\MinGW\msys\1.0\etc\fstab.sample to c:\MinGW\msys\1.0\etc\fstab and also installed automake, libtool, autoconf, aclocal, autoheader dependencies from MinGW installation manager. What am I missing?
I am not familiar with MinGw or unix commands.

PyQt5 error during "python3 configure.py": fatal error: 'qgeolocation.h' file not found

MAC OSX 10.9, Python 3.5, sip-4.17, PyQt-gpl-5.5.1, Qt5.5.1
Hi,
trying to build PyQt on my system I did the following steps:
download/install Qt5.5.1 libraries
download/unpack SIP
download/unpack PyQt
install SIP:
python3 configure.py -d /Library/Python/3.5/site-packages --arch x86_64
make
sudo make install
tried to install PyQt:
python3 configure.py -d /Library/Python/3.5/site-packages
--qmake /.../Qt5.5.1/5.5/clang_64/bin/qmake
Configuration stopped with:
/Users/werner/OpenSource/PyQt/sip/QtPositioning/qgeolocation.sip:28:10:
fatal >error: 'qgeolocation.h' file not found
#include <qgeolocation.h>
^
1 error generated.
make[1]: *** [sipQtPositioningcmodule.o] Error 1
make: *** [sub-QtPositioning-make_first-ordered] Error 2
I tried to finish installation doing
make
sudo make install
anyway. But the installation doesn't seem to be complete (e.g. uic, pyuic5 are missing). Here is what my installation directory looks like:
>ls /Library/Python/3.5/site-packages/PyQt5
QtBluetooth.so QtSensors.so
QtCore.so QtSerialPort.so
QtDBus.so QtSql.so
QtDesigner.so QtSvg.so
QtGui.so QtTest.so
QtHelp.so QtWebKit.so
QtMacExtras.so QtWebKitWidgets.so
QtMultimedia.so QtWidgets.so
QtMultimediaWidgets.so QtXml.so
QtNetwork.so QtXmlPatterns.so
QtOpenGL.so _QOpenGLFunctions_2_0.so
QtPrintSupport.so _QOpenGLFunctions_2_1.so
QtQml.so _QOpenGLFunctions_4_1_Core.so
QtQuick.so
I couldn't find any useful information when searching for other discussions, so I hope someone can give me a hint on what I'm (maybe stupidly) doing wrong. Thank you for taking the time to read this.

If you don't need this module, the better way to solve that is disabling it on configure.
python configure.py --disable=QtPositioning

Just yesterday, I also met such a problem. And this is what I do to solve it:
Create a header file qgeolocation.h in /PyQt-gpl-5.5.1/QtPositioning, and copy the content into it from this website. Then I go sudo make and sudo make install successfully.
Though I do not know whether it is right to solve this problem, fortunately, I installed the PyQt and entered eric6. Hope you make successfully, too.

Adding the location.h header file for me on OSX 10.11.1.
I had the problem in both PyQt-gpl-5.5.1 and PyQt-gpl-5.5.2, but after adding the
file, was able to build.

The way of creating a qgeolocation.h in /PyQt-gpl-5.5.1/QtPositioning worked for me. The QtPositioning.so was created.

You can also take the header file from your qt source folder (you have installed the source files together with binaries, right?), it is located here:
/Src/qtlocation/src/positioning/qgeolocation.h
and then just copy it into:
/PyQt-gpl-X.X.X/QtPositioning/qgeolocation.h
as follows. It should solve the problem in 99.9% cases.

Does anyone know how to compile Megahal on Ubuntu?

I have been trying to compile megahal for a few hours now and i dont seem to be getting anywhere. Has anyone had success with this?
http://megahal.alioth.debian.org/
I keep getting an error that says :
inlined from ‘load_personality.constprop’ at megahal.c:3283:8,
inlined from ‘change_personality.constprop’ at megahal.c:3332:5:

I have installed python via sudo apt-get and i have been over every thread that talks about "'x86_64-linux-gnu-gcc' but I have found no solution

You are getting these errors just because you don't have the python development headers installed. You can install it using following command
sudo apt-get install python-dev ( for python 2.x )
sudo apt-get install python3-dev ( for python 3 )

you need the python developer module "python-dev".this will help you
error: command 'gcc' failed with exit status 1 while installing eventlet
after upgrading to vivid 15.04 on ubuntu i couldn't compile the module anymore so i tried something else. Since in the main folder there is a directory named Megahal with a Makefile in it, i tried to compile from there. First you need to go to that directory.
cd /home/user/Downloads/megahal-9.1.1/Megahal/
you need to go where you unzipped the archive and there you can read the README file and start compiling.
perl Makefile.PL
i copied the missing files i was able to find to that folder and from there
make
make test
but this didn't work for me and afther that
make install
i had to do
sudo make install
and that is all. unfortunately for me i have a problem with perl i think.
I keep getting this error from the module "PL_thr_key" after i load it to the eggdrop. The eggdrop works normally except for the module. No module, no AI and no fun :(

bjam `Unable to find file or target named 'libboost_python'`

What am I missing in my Boost.Python configuration/installation?
I'm trying to compile tutorial example, and I get error with libboost_python not found
cd /usr/share/doc/libboost1.42-doc/examples/libs/python/example/tutorial
bjam

/usr/lib/libboost_python-py27.so.1.42.0
/usr/lib/libboost_python.so -> libboost_python-py27.so
I'm using default libboost packages from Ubuntu 11.04.
My user-config.jam is
using python : 2.7 ;

I had a similar problem on ubuntu 12.04 where I installed all the boost libraries as a package. I found the solution here:
http://jayrambhia.wordpress.com/2012/06/25/configuring-boostpython-and-hello-boost/
It turns out that you do not need to use bjam at all. A makefile suffices. I will repeat the the solution from the above link here:
1.) Install the libboost-python package
2.) Create a hello world source file called 'hello_ext.c':
char const* greet()
{
return "hello, world";
}
#include<boost/python.hpp>
BOOST_PYTHON_MODULE(hello_ext)
{
using namespace boost::python;
def("greet",greet);
}
3.) Create a makefile:
PYTHON_VERSION = 2.7
PYTHON_INCLUDE = /usr/include/python$(PYTHON_VERSION)
# location of the Boost Python include files and library
BOOST_INC = /usr/include
BOOST_LIB = /usr/lib
# compile mesh classes
TARGET = hello_ext
$(TARGET).so: $(TARGET).o
g++ -shared -Wl,--export-dynamic $(TARGET).o -L$(BOOST_LIB) -lboost_python -L/usr /lib/python$(PYTHON_VERSION)/config -lpython$(PYTHON_VERSION) -o $(TARGET).so
$(TARGET).o: $(TARGET).c
g++ -I$(PYTHON_INCLUDE) -I$(BOOST_INC) -fPIC -c $(TARGET).c
4.) make
make
5.) Ready to use. In python:
import hello_ext
print hello_ext.greet()

Still not sure it that's the proper way, seems little hackish, but following helped:
In Jamroot file replaced
project
: requirements <library>libboost_python ;
with
project
: requirements <library>/usr/lib/libboost_python.so ;

You could have a site-config file with something like the following ;
using boost : 1.48 : <include>/usr/include/boost-1_48 <library>/usr/lib ;
(you need the < library > bit, not sure why)
then you can do stuff like.
project foo
: <library>/boost//python
Makes things easier in the long run, as you inevitably will have to change boost version at some point.
