Text Formatting ⇒ Undefined old font command

[danielvelizv]

Hello people! I have a problem, two months ago I full installed Miktex with all packages in my laptop on Windows 7, in another PC I worked a document with the same packages but when I tried to compile the same document in my laptop, it shows me the following error in the attached picture in this post, I don't know what's happening, I have the same number of packages installed on both computers. Can anyone help me on this?

[Johannes_B]

You (or a package you are using) are using font commands that are officially obsolete since 1994. The author of KOMA-script decided to finally encourage people to stop using them.
You can use the global option enabledeprecatedfontcommands, which by definition is also deprecated.

By the way, a minimal working example and an upload of the log-file is much better than a screenshot. I cannot copy the text to run LaTeX on it myself and see the problem. Luckily, in this case the reason is easy to know.

[Stefan Kottwitz]

As an addition, replace \bf by \bfseries or by \normalfont\bfseries.

Or use it like \textbf{...} similar as you already use \textcolor{...}. Such commands can be nested, such as \textbf{\textcolor{...}}.

Thanks buddy. I didn't know that, I was looking for this in a lot of websites, So, for both explanations I read, I have to edit all deprecated commands in my TeX file, no?

[Johannes_B]

That would be a good start. But some packages also use the old font commands, most notably fanyhdr. Using that package with a KOMA class is not recommended anyway, as KOMA-script comes with its own package to style header and footer. It is called scrlayer-scrpage.

That's very good, I don't know how much I have to change my TeX. Is there any possibity to send to any of you (you or Stefan) and check and comment the modifications in my file? I want to learn about scrbook class, regards!

You can post your code here and we can make suggestions.

It's a public forum - would we start moving know-how to private messages it would not have public use anymore.

I hope it will not be a problem on the language because I wrote in Spanish using babel, so here is my code

That's the good thing, the relevant LaTeX code is the same for all of us. There is no language barrier.

Another thing though, you really should have read soma basics about LaTeX. You are doing everything by hand, leaving behind spaghetti code of the worst kind.

I'll see what i can do to slim things up a bit.

[Johannes_B]

The following at least took care of the headers and footers. The rest, it is just too much to invest time in it.

For your next projects, use proper empty lines to separate paragraphs. You are making LaTeX a very hard time by avoiding them.
Don't use \displaystyle in inline mode. It make the text ugly.
Don't number stuff by hand. LaTeX is supposed to do that for you.
There are excellent pacages like exsheets that help you setting up this kind of documents. Also very helpful for what you want to do: tasks.
