Hello,

in one of the latest daily BioC check report for my package I see  "...NOT SUPPORTED" for all platforms but Linux:

Hostname    OS / Arch                                               INSTALL    BUILD    CHECK    BUILD BIN    
malbec2     Linux (Ubuntu 16.04.1 LTS) / x86_64      NotNeeded      OK     [ OK ]        
tokay2     Windows Server 2012 R2 Standard / x64     ...NOT SUPPORTED...NOT SUPPORTED...NOT SUPPORTED...
toluca2     Mac OS X Mavericks (10.9.5) / x86_64     ...NOT SUPPORTED...NOT SUPPORTED...NOT SUPPORTED...
veracruz2     OS X 10.11.6 El Capitan / x86_64          ...NOT SUPPORTED...NOT SUPPORTED...NOT SUPPORTED.

I do not recall using any platform specific features or limiting my package to certain platforms. What can be possible source of this BioC chceck results?

Questions about package development should be sent to the bioc-devel mailing list.

No need to leave us guessing about your package; I guess it's ToPASeq.

From the commit history, I see

mark as unsupported on non-Linux like DEGraph which ToPASeq suggests
------------------------------------------------------------------------

This is apparently through DEGraph's dependency on NCIgraph

------------------------------------------------------------------------

I believe RCytoscape was marked as unsupported because it relies on configurations that the build system cannot easily and consistently implement.

As a package author, you  can remove the dependency on DEGraph (or convince the upstream maintainers to remove their dependency on RCytoscape) and then edit (or in your case remove) the file

Rpacks/ToPASeq$ cat .BBSoptions 
UnsupportedPlatforms: win, mac
