Unable to compile Fedora 20 png png package

I am trying to build an R package png , the repo says libpng should be available.

I am running a Linux Fedora 20 distribution

Looks like I have ...

 [ root@localhost bin]# yum install libpng Loaded plugins: langpacks, refresh-packagekit Package 2:libpng-1.6.3-3.fc20.x86_64 already installed and latest version Nothing to do

But when I try to install it:

 > install.packages("png") Installing package into '/home/statquant/R/x86_64-redhat-linux-gnu-library/3.0 (as 'lib is unspecified) trying URL 'http://cran.rstudio.com/src/contrib/png_0.1-7.tar.gz' Content type 'application/x-gzip' length 24990 bytes (24 Kb) opened URL ================================================== downloaded 24 Kb * installing *source* package 'png ... ** package 'png successfully unpacked and MD5 sums checked ** libs gcc -m64 -std=gnu99 -I/usr/include/R -DNDEBUG -I/usr/local/include 'libpng-config --cflags' -fpic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -c read.c -o read.o /bin/sh: libpng-config: command not found read.c:3:17: fatal error: png.h: No such file or directory #include <png.h> ^ compilation terminated. make: *** [read.o] Error 1 ERROR: compilation failed for package 'png * removing '/home/statquant/R/x86_64-redhat-linux-gnu-library/3.0/png The downloaded source packages are in '/tmp/RtmpG5MjG9/downloaded_packages Warning message: In install.packages("png") : installation of package 'png had non-zero exit status

For some R packages, you need an appropriate development library to successfully install the R package. In your case, this should do what you need

 # Do the following in your terminal (not in an R session) yum install libpng-devel

then you can install the R package

 # Do the following in the R console (during an R session) install.packages("png")

I had the same problem on Ubuntu (16.04) and I decided to use it

 sudo apt-get install libpng-dev
