devSVG.cpp:21:10: fatal error: 'png.h' file not found

[brainprint]

Hi and thank you for your package. I have face this error today.

R version 4.0.3 (2020-10-10) macOS 11.2.1 - Intel svglite 2.0.0

devSVG.cpp:21:10: fatal error: 'png.h' file not found

include

     ^~~~~~~

1 error generated. make: *** [devSVG.o] Error 1 ERROR: compilation failed for package ‘svglite’

[hrbrmstr]

Try running:

brew install libpng

at a Terminal prompt and recompiling.

[brainprint]

Perfect. Thank you very much.

I had the same issue and followed the instructions. It works now. Thanks, @hrbrmstr!

[joelfishbein]

At first I got this error: bash: brew: command not found

I installed Homebrew (https://brew.sh/), then called brew install libpng, and then was able to install svglite as expected.

[cattapre]

Did not work for me. Getting the same error message

[hrbrmstr]

you're missing libpng in your link path somewhere. this works for everyone who has a proper homebrew or macports setup and the png library installed. these are table stakes for doing dev-based installs.

[danmackinlay]

Me neither @cattapre. I wonder if you, like me, have homebrew installed in a non-standard location?

[danmackinlay]

Also @cattapre I find that the problem as arisen in version 2.0.0.

So for me this fails, throwing the error you mention:

devtools::install_version("svglite", version = "2.0.0", repos = "http://cran.us.r-project.org")

But this works fine:

devtools::install_version("svglite", version = "1.2.3", repos = "http://cran.us.r-project.org")

Can you confirm?

Good morning, I am also trying to install svglite and have a similar error. I am on R version 3.6.1, I have libpng installed and up to date. I am getting the following error:

My issue is gone. The binary provided fixed the problem.

I also have this problem. Like @danmackinlay, I too have homebrew installed in a nonstandard location ($HOME/homebrew; this is required by my organization). We are also required to install R via homebrew, which prevents most R binaries from working (they can't find shared libraries where they expect) and forces us to compile from source in most cases.

I can see that png.h is on my computer at homebrew/Cellar/libpng/1.6.37/include/libpng16/png.h. But I don't know the magic words to get the svglite package install process to find png.h in this location.

[imanuelcostigan]

I too have this issue. Have brew config per default, but running on an Apple Silicon Mac.

[thomasp85]

brew behaves differently on silicon and you'll need to alert R to the different location of its libraries

put this in your global .Makevars

CFLAGS=-I/opt/homebrew/include
CPPFLAGS=-I/opt/homebrew/include
CXXFLAGS=-I/opt/homebrew/include
CXX11FLAGS=-I/opt/homebrew/include
LDFLAGS=-L/opt/homebrew/lib

[rohilsaraf97]

Could you please tell me where to find the global .Makevars file on macOS?

[imanuelcostigan]

[RuDevelooper]

Try running:

brew install libpng

Thank you!
