Try your examples with current gretl (1.9.3, but 1.9.4 > will be out before long) and see if the problem is still there.
Ubuntu is a great distro, I use it myself on my laptop, but the gretl version it contains is often outdated (blame it on the blazing speed of gretl's development :-)). Here's a step-by-step guide for building 1.9.3 on Ubuntu (I'm assuming you're a novice: if you find the following condescending/patronising/boring, I'm sorry, but maybe someone else won't): 0) Important: before you do anything else, uninstall the existing version of gretl from your system. There are many ways to do this. I suppose that you, as a Ubuntu user, will find this easy to do via synaptic or other GUI tools. Please be sure to have removed gretl from your PC before you continue. 1) Download the source tarball by visiting this link: http://sourceforge.net/projects/gretl/files/gretl/1.9.3/gretl-1.9.3.tar.bz2/download 2) The tarball contains a directory called "gretl-1.9.3"; unpack it where you want (your home folder will do just fine; I keep mine as a subdir of $HOME/src/, but it's just a matter of taste). From here on, I'll assume you unpacked it in your $HOME, so you have a subdirectory ~/gretl-1.9.3/, which contains loads of stuff (a "Changelog" file, a "Compatlog" file, a "lib" subdirectory, etc.) 3) Now, install all the stuff you need for building gretl: open a terminal and execute the following commands: sudo apt-get build-dep gretl sudo apt-get install texlive-latex-recommended texlive-latex-extra You may be able to do this via synaptic, but I wouldn't know how to do it; besides, you'll have to use the terminal anyway for the next steps, so you'll might as well start here. 4) while still in the terminal, navigate to the source directory via the "cd" command, as in cd ~/gretl-1.9.3 5) now execute the command ./configure --enable-build-doc --enable-quiet-build you should see quite a few messages and, at the end, something like Now type 'make' to build gretl. You can also do 'make pdfdocs' to build the PDF documentation. 6) Build gretl by executing "make", as in make the terminal will show you what the compiler is doing, with lines like CC adf_kpss.lo CC bhhh_max.lo CC bootstrap.lo CC boxplots.lo CC calendar.lo CC compare.lo ... Ubuntu's version of gcc is set in such a way that you'll also see lots of warnings on missing return values; don't panic, they're totally harmless. Ignore them. Really. 7) Install gretl: sudo make install Again, this will take a while, and you'll see your terminal full of messages. That's ok. It should stop after something like: make[2]: Entering directory `/home/yourname/gretl-1.9.3/share/bcih' cp -fp fedstl.bin /usr/local/share/gretl/db/fedstl.bin cp -fp ../../share/bcih/fedstl.idx /usr/local/share/gretl/db/fedstl.idx make[2]: Leaving directory `/home/yourname/gretl-1.9.3/share/bcih' make[1]: Leaving directory `/home/yourname/gretl-1.9.3/share/' 8) Give it a go: run gretl. If all is well, you ought to see gretl start, at which point just exit the program in the usual way. Life is fine. On the other hand, there is the possibility that gretl doesn't start and instead you see a message like /usr/local/bin/gretl_x11: error while loading shared libraries: libgretl-1.0.so.0: cannot open shared object file: No such file or directory In this case, just run sudo ldconfig The problem should be fixed once and for all. 9) Close the terminal and enjoy a modern gretl version.
