I cannot install ChAMP under Ubuntu 18.04 in R 3.4.4, it shows the error:

it shows:

Warning message:
In install.packages(pkgs = doing, lib = lib, ...) :
  installation of package ‘ChAMP’ had non-zero exit status

it shows the same error when I tried ChAMP 2.10.1/2.10.0 by using 'R CMD INSTALL PACKAGE'

Further I set 'R_MAX_NUM_DLLs=2000' in .Renviron the same error repears.

I check the DLLs by using:

> Sys.getenv('R_MAX_NUM_DLLs', unset=NA)
[1] "2000"
> length(getLoadedDLLs())
[1] 15

So my setting in .Renviron works, however the setting cannot resolve the error.

How will I do？ Thanks.
