How to identify the tools selected by waf?

Question

How can I determine which specific waf tool is selected as "cxx_compiler" etc.? Examples of using:

def configure(ctx): print('Running ' + ctx.cmd + ' in ' + ctx.path.abspath() ) ctx.load('compiler_c') ctx.load('compiler_cxx') def build(ctx): print('Running ' + ctx.cmd + ' in ' + ctx.path.abspath() ) # Here print which C++ compiler was chosen print 'Building cpp files with %s' % WHAT_GOES_HERE 

Answer 1

 def options(opt): opt.load('compiler_c') opt.load('compiler_cxx') def configure(cfg): cfg.load('compiler_c') cfg.load('compiler_cxx') def build(bld): print "Compiler is CC_NAME %s CC %s"%(bld.env.CC_NAME,bld.env.CC) print "Compiler is CXX_NAME %s CXX %s"%(bld.env.CXX_NAME,bld.env.CXX) 

You'll get:

 D:\temp>waf.bat configure build --check-c-compiler=gcc --check-cxx-compiler=g++ Setting top to : D:\temp Setting out to : D:\temp\build Checking for 'gcc' (c compiler) : c:\tools\gcc\bin\gcc.exe Checking for 'g++' (c++ compiler) : c:\tools\gcc\bin\g++.exe 'configure' finished successfully (0.191s) Waf: Entering directory `D:\temp\build' Compiler is CC_NAME gcc CC ['c:\\tools\\gcc\\bin\\gcc.exe'] Compiler is CXX_NAME gcc CXX ['c:\\tools\\gcc\\bin\\g++.exe'] Waf: Leaving directory `D:\temp\build' 'build' finished successfully (0.008s)
