Why is PROJ4/cs2cs reprojection latlon to lcc NAD83 generating sys errno:2

Question

I am trying to use PROJ4/cs2cs to change the projection of latlon coordinates from latlon to lcc. I have the NAD83/NAD27 in the proj/nad directory and have rebuilt and installed PROJ.

Can someone tell me why I'm getting this sys errno message when I try to run the following code?

cs2cs +proj=latlon +datum=WGS84 +to +proj=lcc +lat_1=49 +lat_2=77 +lat_0=40 +lon_0=-95   +x_0=0 +y_0=0 datum=NAD83 +ellps=GRS80 +units=m +no_defs ifile.txt | tee ofile.txt

<cs2cs>:
Sys errno: 2: <system mess. texts unavail.>
datum=NAD83

Answer 1

You just forgot '+' in front of 'datum' command ;)

datum=NAD83 -> +datum=NAD83
