TeX Live and MacTeX ⇒ 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?

[El Tito]

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

\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.
