[GRASS-dev] configurare fails: Failed check for math library

[Nicklas Larsson]

Martin,

Noting that you use a non-default prefix, you may need to add `LDFLAGS="-L/usr/lib”` (and perhaps add ´”-I/usr/include” to CFLAGS and CXXFLAGS).
The same result could perhaps be reached with `--with-includes=/usr/include --with-libs=/usr/lib` added to configure, although that I’m not sure of.


Best,
Nicklas
