[Scons-users] Builder execution order?

[delbert dev]

Same result:

*user at ubuntu:~/tmp/af_test$ **scons --tree prune .*
*scons: Reading SConscript files ...*
*scons: *** source file [gtest-1.7.0.zip] must be exist  Stop.*

I have also tried with the Depends

*http://www.scons.org/doc/0.96.1/HTML/scons-user/x959.html
<http://www.scons.org/doc/0.96.1/HTML/scons-user/x959.html>*


env = Environment()
*gtestUrl = buildUrl('com.google', 'gtest', '1.7.0', 'zip')*
gtestOutputFile = 'gtest-1.7.0.zip'
*env.Tool('URLDownload', '#site_scons/site_tools')*
env.Tool('Unpack', '#site_scons/site_tools')
*env.Replace(URLDOWNLOAD_USEURLFILENAME =  False )*
*ouutdir = Entry('outdir')*
a = env.Alias('abc', env.URLDownload(gtestOutputFile, gtestUrl))
b = env.Alias('xyz', env.Unpack( ouutdir, gtestOutputFile ))
*Depends(a,b)*


*user at ubuntu:~/tmp/af_test$ **scons*
*scons: Reading SConscript files ...*
*scons: *** source file [gtest-1.7.0.zip] must be exist  Stop.*
