[jamming] Jam commands to build a specific file

[Kai Backman]

 Hi Craig,

 Here is your Jamfile slightly rewritten:

---<snip>---
C++ = g++ ;
LINK = g++ ;

rule Resource
{
  # This used to be Resource (typo?)
  DEPENDS $(<) : $(>) ;
}

actions Resource
{
  windres $(>) $(<) -Iassets\\graphics
}

SRC = [ FDirName src platform Windows entry.cpp ] ;
RES_FILE = [ FDirName src platform Windows resources.res ] ;

DEPENDS all : mytest ;

# By using INCLUDES you force the exe to depend on the rc file
# and thus make jam update it before it compiles the exe (which
# is usually what you want). You could alternatively do this instead:
# DEPENDS [ FDirName path to mytest.exe ] : $(RES_FILE:S=.rc) ;
INCLUDES $(SRC) : $(RES_FILE:S=.rc) ;

Resource $(RES_FILE:S=.rc) : $(RES_FILE) ;

# Get the rc file on the link command line
LINKFLAGS = $(RES_FILE:S=.rc) ;

Main mytest : $(SRC) ;
---<snip>---

 Let me know if this solves what you had in mind.

 Take care,

 Kai
