Using Rake to build C++
Magnus Falk
6/5/2007 9:11:00 PM
I'm making myself a build environment and found this Rake thingy that
seemed just to good to pass upon. But since I don't know any Ruby I'm
struggling a bit.
I'm making a couple of tasks to compile and link C++ code and it seems
like I've misunderstood the file task somewhat. In the example code
below, the compilation and linking is never run, what am I doing wrong?
cppTasks.rb:
def compileTask inclDirs, flags
inclDirs = inclDirs.collect { |dir| '-I' + dir }
inclDirs = inclDirs.join(' ')
flags = flags.join(' ')
SRC_FILES.each do |srcFile|
objFile = File.join(OBJ_DIR, srcFile.pathmap("%f").ext('o'))
file objFile => [srcFile] do
sh "g++ #{inclDirs} #{flags} -c #{srcFile} -o #{objFile}"
end
end
end
def linkTask libDirs, libs, flags, target
libDirs = libDirs.collect { |dir| '-L' + dir}
libs = libs.collect { |lib| '-l' + (lib[/lib(.+)\./, 1])}
flags = flags + ((File.extname(target) == '.so') ? ['-shared'] :
['-c'])
libDirs = libDirs.join(' ')
libs = libs.join(' ')
flags = flags.join(' ')
targetFile = File.join(BUILD_DIR, target)
file targetFile => OBJ_FILES do
objFiles = OBJ_FILES.collect { |objFile| objFile + ' ' }
sh "g++ #{libDirs} #{libs} #{flags} #{objFiles} -o #{targetFile}"
end
end
Cheers,
Magnus

Oh, another thing while I'm at it. Is there any way to "export"
variables defined in one task to make them visible in other task?
Similar to "antcall"
(
http://ant.apache.org/manual/CoreTasks/an...
) with the flag
inheritAll.
I'm having problems with dependencies between variables and I would like
to have a little more control over when they are assigned instead of
just at the moment when they are imported.
