Convenience functions for HDFql API for R
Home Page: http://hydroecology.net/hdfqlr/
Dear Michael,
I am trying to use hdfqlr on Ubuntu, and I am not able to get it running.
> hql_load('/home/dallinger/hdfql-2.5.0/')
Error in dyn.load(dll, local = FALSE, now = TRUE) :
unable to load shared object '/home/dallinger/hdfql-2.5.0/wrapper/R/libHDFqlR.so':
libHDFql.so: cannot open shared object file: No such file or directory
I have set environment variables as suggested in the Reference manual:
export LD_LIBRARY_PATH=/home/dallinger/hdfql-2.5.0/wrapper:/home/dallinger/hdfql-2.5.0/lib:$LD_LIBRARY_PATH
I have also tried an older version (2.2.0) but the problem persits.
I am hoping for any suggestions. The strange thing is, that the error message is that "libHDFql.so" can not be loaded, although it shoudl "libHDFqlR.so"? Also tried loading the dll directly, since this seems to be the part that is failing, but still no luck:
> dyn.load("/home/dallinger/hdfql-2.5.0/wrapper/R/libHDFqlR.so", local = FALSE, now = TRUE)
Error in dyn.load("/home/dallinger/hdfql-2.5.0/wrapper/R/libHDFqlR.so", :
unable to load shared object '/home/dallinger/hdfql-2.5.0/wrapper/R/libHDFqlR.so':
libHDFql.so: cannot open shared object file: No such file or directory
Best Gregor
Add helper function to download HDFql to a directory (default %LOCALAPPDATA%
or ~/.hdfql
). Query the website downloads index: https://www.hdfql.com/releases/
Since LD_LIBRARY_PATH
must be defined before starting R, check that path is correct before attempting to load the HDFql shared libraries and return an informative error message. This is not necessary on Windows.
Use GitHub actions to download HDFql, modify LD_LIBRARY_PATH, and run tests.
