I am reporting two bugs during the installation of Rgraphviz on a CentOS cluster with GCC 7.1. I did not investigate into the cause for these two bugs, but I hope this report will shed some light on a long-standing problem encountered by Rgraphviz users.

The first bug is the <gvc.h> not found error reported by other users but the solution does not require a separate installation of graphviz. I noticed these error messages:
```
cp: cannot stat '/tmp/RtmpzOzXHN/R.INSTALL13d1c949152/Rgraphviz/src/libunix/lib/*': No such file or directory
cp: cannot stat '/tmp/RtmpzOzXHN/R.INSTALL13d1c949152/Rgraphviz/src/libunix/lib/graphviz/*': No such file or directory
```
and examined the temporary installation directory to find that there is indeed no libunix but instead libwin. This explains why it couldn't find the header files which are also in libwin. Our temporary solution is to create a symlink libunix -> libwin/x64 after the installation begins.
The second bug is an unrecognized compiler flag:
```
gcc: error: unrecognized command line option '-wd269'
```
Our temporary solution is to remove this flag from all files by monitoring the installation with a script. I provide a copy of the script in case anyone else would like to use it. Run the script after the installation begins. (It is something I put together quickly and so it may not be foolproof. Customization may be needed.)

When I was trying to redo this, I might have found a third bug.

Towards the end as the installation enters the 3rd instance of

Libraries have been installed in:
   /tmp/Rtmp*/R.INSTALL*/Rgraphviz/src/libunix/lib/graphviz

If these lines are shown:

cp: will not overwrite just-created '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libgvplugin_core.a' with '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libunix/lib/graphviz/libgvplugin_core.a'
cp: will not overwrite just-created '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libgvplugin_core.la' with '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libunix/lib/graphviz/libgvplugin_core.la'

cp: will not overwrite just-created '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libgvplugin_dot_layout.la' with '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libunix/lib/graphviz/libgvplugin_dot_layout.la'
cp: will not overwrite just-created '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libgvplugin_neato_layout.a' with '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libunix/lib/graphviz/libgvplugin_neato_layout.a'
cp: will not overwrite just-created '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libgvplugin_neato_layout.la' with '/tmp/Rtmp3NvhjF/R.INSTALL14086e31ea0d/Rgraphviz/src/libunix/lib/graphviz/libgvplugin_neato_layout.la'

immediately pause the installation (Ctrl-Z), go to the src directory, and copy the library files manually:

cp libunix/lib/graphviz/* .

Then resume the installation and it should finish shortly.

If I do not do this I end up with the following error at the very last linking step:

/usr/bin/ld.gold: error: libgvplugin_dot_layout.a: member at 1326 is not an ELF object
/usr/bin/ld.gold: error: libgvplugin_neato_layout.a: member at 11248 is not an ELF object
/usr/bin/ld.gold: error: libgvplugin_core.a: member at 1212 is not an ELF object
collect2: error: ld returned 1 exit status
make: *** [Rgraphviz.so] Error 1
