Hi, I am probably doing something wrong, but have run out of ideas to check and have not found anything on the web. I am building some R-packages accessing EUMETSAT NWCSAF PPS and EUMETSAT OSISAF HDF5 products. To ensure portability I have attempted to use autoconf. This is my first attempt to use autoconf and followed the description within "Writing R-packages". The problem is that when I run configure manually, it generates the Makevars file as requested. However, when I run it through the R interface as: R CMD INSTALL --configure-args="--with-satimg=/home/steingod/software/libs/libsatimg --with-osihdf5=/home/steingod/software/libs/libosihdf --with-hdf5=/disk1/hdf5lib-1p6p4" osisaf_0.1.tar.gz it fails to substitute LDFLAGS. CPPFLAGS, CFLAGS and LIBS are working fine. Have anyone experienced similar trouble? Any help would be much appreciated.
