I tried to \input
in my main document file a standalone
section, which uses the subcaption
package. The standalone
file compiles just fine. But when I try to compile the main document I get an
Undefined control sequence
error in caption3.sty
.
The error is caused by the \usepackage{subcaption}
alone, so it even occurs when subcaption
is not actually used.
Here is a minimal working example:
main.tex
:
\documentclass{scrartcl}
\usepackage[subpreambles]{standalone}
\begin{document}
\input{subcaption_with_standalone}
\end{document}
subcaption_with_standalone.tex
:
\documentclass{standalone}
\usepackage{subcaption}
\begin{document}
This does not even use a subfigure.
\end{document}
How can I make subcaption
(or something similar, preferrably not deprecated) work with standalone?

Several packages use the
\AtBeginDocument
command. When these packages are loaded in the preamble of a sub-file, these commands will never be executed.The option
subpreamples=true
is thought for macros and alike, not for loading packages. If you need the package in your sub-file, you have to load it in your main file as well. Alternatively, you may just compile your sub-file with all packages you need and run the main file without the optionsubpreambles=true
.Loading
subcaption
in the main preamble works:main.tex
subcaption_with_standalone.tex
