I'm trying to install trainable-tokenizer. I have installed all the dependencies as per the README. this is trainable-tokenizer https://github.com/jirkamarsik/trainable-tokenizer. i have installed quex.deb using installer from quex.org which is a dependency for trainable-tokenizer.
when i try to do sudo make install i get the following error
ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ sudo make install

Environment variable QUEX_PATH has not been defined.

[ 6%] Building FeaturesReader with quex
Environment variable QUEX_PATH has not been defined.
error: environment variable 'QUEX_PATH' is not defined.
error: your system is 'posix'.
but still i get the same error.
I fixed the issue using the -I flag. I had to use quex -I.
I would guess that the real problem is that your python is python 3.0+
and not python 2.7 as required for Quex.
Admittedly, the error message does not tell this directly.
I have a C++ project and I´m using Eclipse CDT 3.8.1 as the IDE tool, with a workspace of 5 different projects...
One of my projects is a shared library, and at the end of compilation I want to copy its code to a test/bin directory for testing.
I´ve gone to Project Properties -> C/C++ Build -> Settings -> Build Steps and at "Post-build steps", "Command", I´ve added:
cp *.so ../../../bin
(OBS: ../../../bin is the correct path from the Debug folder - I´ve checked already).
What happens is that I get the following error on post build:
cp *.so ../../../bin
cp: cannot stat ‘*.so’: No such file or directory
I said: ok, this may be a permission problem, so I changed the post commands to:
whoami;ls -al; ls *.so;
And I got on Eclipse console:
whoami
aeidev
ls -al

ls *.so

And them I changed again to ls *.so and I got:
ls -al *.so
ls: cannot access *.so: No such file or directory
15:57:50 Build Finished (took 715ms)
It´s a very strange behaviour. In the same workspace I have a different shared library and the original cp *.so works fine...
Any ideas of what´s going on here ?
Is it a known Eclipse bug ?
Thanks for helping...
I believe the commands are not executed in a shell by default, so wildcards are not evaluated. Try executing like /bin/sh -c 'cp *.so ../../../bin/'. Also you should use Eclipse's built-in variables to copy to the desired path.
Building pHash 0.9.4 on OSX can turn out to be tricky.
For those of you who've run into issues, my somewhat lengthy answer below might help.
Make sure you've got macports fully updated and working. This means a recent Xcode, and inside Xcode preferences->downloads->components install Command-Line Tools !
$ sudo port selfupdate
# if you've had previous build issues:
$ sudo port clean --all
# get pHash
wget http://www.phash.org/releases/pHash-0.9.4.tar.gz
tar zxvf pHash-0.9.4.tar.gz
cd pHash-0.9.4
# remove old versions of ffmpeg, e.g.
$ sudo port installed ffmpeg
$ sudo port uninstall --follow-dependents ffmpeg #0.7.11_1+mmx
$ sudo port uninstall --follow-dependents ffmpeg #0.7.8_0
# install latest ffmpeg-devel version (#20120329 for me) - enable the non-free stuff as well
$ sudo port install ffmpeg-devel +nonfree
# double check that you have some new header files
$ ll -tr /opt/local/include/

# now run configure, with Java enabled as you likely want those cool bindings, and expect the missing libavcodec error:

OR this which would make more sense:
$ ./configure --enable-java CPPFLAGS="-I/opt/local/include" LDFLAGS="-L/opt/local/lib"
but configure completely ignores the new include/lib paths stated :( Seemingly as they're hardcoded inside configure.
...
checking CImg.h usability... no
checking CImg.h presence... no
checking for CImg.h... no
checking whether CImg.h is in the current or src directory.... yes
*** Configuring video Hash ***
checking whether FFmpeg is present... checking for avcodec_alloc_frame in -lavcodec... no
configure: error:
*** libavcodec not found.
So then since configure expects all the libs and includes to be in /usr/local/ (not /opt/local) and I cant't get it to look elsewhere, the only thing left to do is brute-force it ! :D
# edit ./configure as follows
$ nano configure
CTRL-W -> search for ' -L/' (note the space)
# edit the lines as follows
LDFLAGS="$LDFLAGS -L/usr/local/lib -L/opt/local/lib"
CPPFLAGS="$CPPFLAGS -I/usr/local/include -I/opt/local/include"
# Or do the newbie version (I actually did this the first time!)

When I tried to compile a [.cpp] file to [.swc] file, I got this:

And I found that my libltdl is

How to solve it?
According to the post here

The following set of commands would work( i tested, too )
cd /usr/lib/
sudo ln -s libltdl.7.dylib libltdl.3.dylib
I am trying to compile the latest Boost c++ libraries for Centos. I 've used bjam install and it has placed the libraries in /usr/lib and /usr/lib64.
The problem is I need the -mt variants for a specific application to run. I cannot understand in the documentation how to create the multithreading variants. :(
Please give me a hint!
Thanks!
-mt is just distribution specific extension.
either edit your config file or create symbolic link to libboost_thread

You can build all variations of the boost binary libraries using the --build-type=complete option. For example:
bjam --build-type=complete stage
This will put all library files into <your boost dir>/stage/lib/
