General ⇒ Installed but got an error using subcaption package

[hzmonte]

I read that subfig is deprecated and one should use the subcaption package. I installed it and have the following files in my working directory:

Code: Select all

% ls *sty
bicaption.sty  caption2.sty  caption3.sty  caption.sty 
                                                            ltcaption.sty  newfloat.sty  subcaption.sty

I also have them in ~/texmf/tex
I also did a texhash
But when I ran latex, I got an error as follows.

Code: Select all

% make 
pdflatex modelpaper; bibtex modelpaper; pdflatex modelpaper; pdflatex modelpaper; \
        bibtex modelpaper; pdflatex modelpaper; dvips -Pwww -t letterSize modelpaper.dvi; rm core

What's wrong?

I installed it

How exactly did you installed it?

Code: Select all

! Undefined control sequence.
l.752 \cs
         {DeclareCaptionDefaultJustification}}
? 

What's wrong?

There is only one occurrence of \cs{DeclareCaptionDefaultJustification}, in caption3.dtx:

Code: Select all

% \changes{v1.2a}{2008/01/31}{Renamed from \cs{DeclareDefaultCaptionJustification} to \cs{DeclareCaptionDefaultJustification}}

This is code intended for the changelog only and should not occur in one of the resulting *.sty files.

So your installation of the subcaption package is faulty.

I recommend removing the faulty files, going to http://mirrors.ctan.org/install/macros/latex/contrib/, getting caption.tds.zip, unzipping it, and putting its contents to ~/texmf/.

[hzmonte]

I installed the package by "latex caption.ins". And I reviewed the caption.log after installation and it does not indicate any error.
I am going to re-install it. Thanks.

Why don't you just install the package by the package manager of your TeX distribution?

I re-installed it, using "latex caption.ins" and now there is no error. I don't know how to use "the package manager of [my] TeX distribution".

[localghost]

[…] I don't know how to use "the package manager of [my] TeX distribution".

Then you should take a look at its manual. Every common TeX distribution has a package manager which makes manual package installation superfluous. But if you don't tell us what distribution you have installed, you won't get specific help in this regard.

[sommerfee]

I re-installed it, using "latex caption.ins" and now there is no error.

Anyway, it seems that your way of installing LaTeX packages is not very reliable. I suspect that you have saved the *.dtx files as text files (copy-paste?), and during this process an extra (unwanted) line break was inserted into caption3.dtx. (Since the unpacking process via *.ins file is quite dumb such problems will not be detected automatically.)

So better use zip files for download, this way you get sure that its contents will not get corrupt.

[hzmonte]

Yes, I did use copy-and-paste to save a couple dtx files!
Now that there is no error, I'd set aside the package manager issue.
Now I notice that the following message appears when I latex my .tex file:
"Package caption Warning: Unsupported document class (or package) detected,
(caption) usage of the caption package is not recommended.
See the caption package documentation for explanation."
Anyone knows the specific reason why "caption" is not recommended? Isn't it preferred over subfig.sty?

[localghost]

Why don't you just say which TeX distribution you have installed? With its package manager your problem could have been solved already well before. m(

[hzmonte]

I do not know what TeX distribution the system administrator installed on my system. Is there a way to find out?
Is it related to the "caption" warning message?
