Not finding texlive packages

[El Tito]

Hi everybody, I don't know if this topic would fit better in texmaker,kile or texlive, because it has a little of each.
I'll try to explain my problem as clear as I can.

I'm an ubuntu user (natty), and a couple of months ago I created a tex document
containing the commands underbracket,eqqcolon... belonging to the mh bundle, amsmath and amscls packages. Then, the compiling process ran smoothly, but now I can't figure out what had I done (I think I had installed the individual packages).

So after googling and forum reading a little, I decided to install texlive 2011, assuming the packages previously mentioned are contained in texlive (thats what I've read). I tried to compile my document with kile and texmaker, but it seems neither finds the packages, cause I get the undefined control sequence errors in underbracket and eqqcolon everytime I tex the doc.

I tried to put the individual packages in /usr/local/texmf , in /usr/share/texmf , and in ~/texmf (as I read on several pages), with no success. I tried too, to change the path in preferences->commands (texmaker), the same in kile, but still nothing.

Any insights?, thank you very much in advance.

Hi,
could you attach your log file?

Of course, sorry for not attaching the log file by default. Thank you for your quick reply, the log is attached.

Hi,

i see two errors, one caused by \eqqcolon and the other concerning \underbracket.
Add

Code: Select all  •  Open in writeLaTeX

\usepackage{mathtools}% or \usepackage{pxfonts}
\usepackage{underbracket}

to your header. That should work.

It was as simple as including the package name in the headers.
I had no idea, so everytime I need a command included in a package,
I need to call it previously in the tex file.
Thank you very much.
