title: "/usr/bin/ld: cannot find library"
body: <p>This is my first time trying to compile FORTRAN code using a makefile. The OS is Ubuntu 12.04 LTS 64 bit. I encountered the following errors:</p>
  
  <pre><code>gfortran  -o przm3123.exe canopy.o chem.o cnfuns.o cropdate.o datemod.o debug.o debug_cn.o f2kcli.o floatcmp.o furrow.o general.o i_errchk.o infnan.o inivar.o ioluns.o iosubs.o lambertw.o m_readvars.o utils.o wind.o fcscnc.o przm3.o rsexec.o rsinp1.o rsinp2.o rsinp3.o rsmcar.o rsmisc.o rsprz1.o rsprz2.o rsprz3.o rsprzn.o rsutil.o rsvado.o -L ../libanne4.0/lib -lwdm -ladwdm -lutil
  /usr/bin/ld: cannot find -lwdm
  /usr/bin/ld: cannot find -ladwdm
  collect2: ld returned 1 exit status
  make: *** [przm3123.exe] Error 1
  </code></pre>
  
  <p>The key element in the makefile is:</p>
  
  <pre><code>przm2_LIBS = -L ../libanne4.0/lib -lwdm -ladwdm -lutil
  </code></pre>
  
  <p>Is there anything I can do to fix this error? Should I try other compilers?</p>
