[Rcpp-devel] r-forge error: undefined symbol: zgetri_

[baptiste auguie]

Hi,

My Makevars contains the following line,

## Use the R_HOME indirection to support installations of multiple R version
PKG_LIBS = $(shell $(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()" )
$(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)


which I obviously took from somewhere, perhaps automatically generated
from package.skeleton, I don't remember. It's worked for me on two
different machines (both Macs, though).

Best regards,

baptiste
