wmake tips:
+
 
+
- all invocations can have an optional directory:
+
  wmake $FOAM_UTILITIES/mesh/manipulation/checkMesh
+
  wmake libso $FOAM_SRC/finiteVolume
+
 
+
- wmake all
+
  wmake all <dir>
+
will recursively build all applications in current or specified directory.
+
 
+
- wmake <target>, e.g.
+
  wmake Make/linux64Gcc4DPOpt/meshBb.o
+
will build just that taget
+
 
+
- distributed building:
+
wmake comes with a simple scheduler, wmakeScheduler, which spawns a job on a free machine. It is currently set up to distribute only compilation of c,c++. Dependency building and linking gets done on the local machine.
+
 
+
It is set up with environment variables:
+
 
+
WM_SCHEDULER : the name of the scheduler to use
+
 
+
WM_HOSTS    : the list of cores to use
+
 
+
WM_NCOMPROCS : the number of parallel builds (usually the size of WM_HOSTS)
+
 
+
WM_COLOURS  : Optional{{Version1.5}} : per entry in WM_HOSTS the colour to use. This is used in 'setterm -foreground XXX' ; for this to work I have to set my TERM environment variable to 'linux'.
+
 
+
 
+
Example to build on 1 processor of dm and 4 processors of noisy:
+
 
+
{{VersionInfo}}{{Version1.4.1}}:
+
 
+
export WM_SCHEDULER=wmakeScheduler
+
 
+
export WM_HOSTS="dm:1 noisy:4"
+
 
+
export WM_NCOMPPROCS=$($WM_SCHEDULER -count)
+
 
+
 
+
{{VersionInfo}}{{Version1.4}}:
+
 
+
export WM_SCHEDULER=wmakeScheduler
+
 
+
export WM_HOSTS="(dm:0 noisy:1 noisy:2 noisy:3 noisy:4)"
+
 
+
eval "hosts=$WM_HOSTS"
+
 
+
export WM_NCOMPPROCS=${#hosts[@]}
