BFL-dev

I am new to using BFL, well i'm really new to linux as well as g++ so this post might sound stupid to some experts.Neways i was trying to compile the test_linear_kalman.cpp found in the /orocos-bfl-0.6.1-src/examples/linear_kalman folder using the command
g++ -o test_linear_kalman.cpp
and the following errors were returned

i think the problem is that the bfl as well as the LTI and boost files are installed in /usr/local/include folder
while the rest of the header files(fstream, iostream etc) are in /usr/include folder. i'm just guessing

any help will be appreciated.

You should have a look at the getting started guide which gives a step by step
guide to get the tutorial examples (and the library) working:
http://people.mech.kuleuven.be/~tdelaet/bfl_doc/getting_started_guide/

If you still have problems after reading the getting started guide, don't
hesitate to contact the mailing list again.

i had read those docs but they dont give specific commands for compiling the examples... or mayb i'm just not looking at the right place..
but i found a similar post here and used the command
sudo g++ -o test_linear_kalman `pkg-config --cflags orocos-bfl` test_linear_kalman.cpp `pkg-config --libs orocos-bfl`
now it is giving only one error --

any ideas to how to fix this??

Also have a look at the bfl installation guide.
BFL makes use of ccmake. If you set the option to build the examples on, the
executables are automatically generated.
You can find the installation guide here:
http://people.mech.kuleuven.be/~tdelaet/bfl_doc/installation_guide/

"BFL makes use of ccmake. If you set the option to build the examples on, the

but those binaries dont allow me to understand the code by actually hacking it....thats why i wanted to compile it first hand...
the binaries generated during the installation work fine for me..

guys please shed some light on this error...

sudo g++ -o test_linear_kalman `pkg-config --cflags orocos-bfl`

I think you misunderstood the procedure.
Undoubtly you could also compile the code using g++ but I already provided all the tools for using ccmake which makes your live (and certainly the linking) a lot easier.

I copied the procedure below from the installation guide (everything which is italic )and I added some clarifications:

Install BFL itself
Now we arrived to the installation of the BFL library itself. BFL is available from our subversion server, or as a tarbal.

First go to the $ \mathtt{\tilde{ }}$ /sources/ folder:
cd ~/sources/

Then, to get a copy of BFL, use
For subversion access:
svn co http://svn.mech.kuleuven.be/repos/orocos/trunk/bfl

Like this you check out the SOURCE code which also means you will check out the source code of the examples. Like this you can fool around with the examples and change them as you want.

Now create and go to a build directory in /sources/bfl
mkdir ~/sources/bfl/build
cd ~/sources/bfl/build

Run ccmake:
ccmake ..

Running Cmake will do all the linking for you! If you set the correct options (see further on) it will also build the examples for you. So if you altered the source code of the examples, it will try to compile the files you changed!

Then type 'c' to configure, and 'e' to exit the page that shows the configure output. Now you see the cmake configuration menu. In this menu you can change the following options:
BUILD_EXAMPLES: ON if building the examples is desired,
BUILD_TESTS: ON if building the cppunit tests is desired,
CMAKE_BUILD_TYPE: Debug or e.g. Release,
CMAKE_INSTALL_PREFIX: directory where to install bfl, e.g. /install,
CPPUNIT_INSTALL: directory where the CPPUNIT is installed, e.g. /usr,
GINAC_INSTALL: directory where GINAC is installed, e.g. /usr,
GINAC_SUPPORT: OFF if you don't want to use GINAC support,
LIBRARY_TYPE: type of library build, shared or static,
MATRIX_INSTALL: directory where the matrix library is installed: e.g. /usr,
MATRIX_LIB: matrix library used: boost, lti or newmat,
RNG_INSTALL: directory where the random number generator is installed: e.g. /usr,
RNG_LIB: random number generator used: boost, lti or scythe.
Now repeat the 'c' configure and 'e' exit cycle, until you get no more errors. When this is the case, you'll have the 'g' generate option available. Press 'g' to generate the makefiles, and then quit cmake with 'q' quit.

The build examples option should be ON of course!

Now all configuration is done, and you can build BFL:
make

To check the functionality of BFL, use
make check

To install BFL use
sudo make install

Summary: just following the procedure for installing BFL it will also compile the examples included in the source of BFL.
If you want to create your own examples with their own build system, then have a look at the CMake files (e.g. CMakeList.txt) to set the correct build and linking options.

Hope this helps.

root@watt:~ #
cat /usr/lib/pkgconfig/liblti.pc
Name: liblti
Description: LTI library.
Version: 1.9.15
Libs: -L/usr/lib/ltilib -lltir
