[Bioc-devel] Build fail due to "undefined color `fgcolor`"

Dear Mike,

Build error messages for my packages still exist after a few days. I am
wondering how long the error will last. Thank you so much for your great
help!

Many thanks!

This looks to be an issue introduced by changes in knitr 1.47.0, which
lead
to an incompatibility in the BiocStyle Rnw template.  We're working on a
patch to BiocStyle, which should be deployed on the build machines today,
and will hopefully fix the issue in the affected packages. The is nothing
package authors need to do at this time.

I'll report back here on the status after the update has been rolled out.

Best wishes,
Mike

I also received the same error email for my packages BUScorrect and
HIREewas. I don't know how to fix these "undefined color" issues.

Thank you very much for all your help and replies!

Best regards,

This seems to me like a change in the xcolor package, but I'm not

sure. I

opened an issue on the BiocStyle package at

Dear Bioc Team,

I got today a build error from OUTRIDER and FRASER with:

LaTeX errors:
! Package xcolor Error: Undefined color `fgcolor'.

The same errror also pops up at other packages such as ggbio:

output file: ggbio.tex
! Package xcolor Error: Undefined color `fgcolor'.

I have the same error. I suppose there's an issue with BiocStyle.
After some debugging I found out that adding

\definecolor{fgcolor}{rgb}{0.345, 0.345, 0.345}
\newcommand{\hlsng}[1]{\textcolor[rgb]{0.192,0.494,0.8}{#1}}%
\newcommand{\hldef}[1]{\textcolor[rgb]{0.345,0.345,0.345}{#1}}%

right after the `BiocStyle::latex()` chunk fixes the issue.
