[Scons-users] Ninja compilation fails after using include path file instead of "-I" option

[Daniel Moody]

hello liruncong,

You can not directly use the @ response file syntax with ninja, you should
instead use SCons internal feature for this, TEMPFILE, as the ninja tool
will know how to process that.

TEMPFILE is meant to be substituted in the full command line, here is an
example how to make your CC compile commands use the tempfile:

env['_RT_CCCOM'] = env['CCCOM']
env['CCCOM'] = "${TEMPFILE('$_RT_CCCOM', '$CCCOMSTR')}"

Here is a diff of your project where I am using the response file in scons
and it works with ninja:

diff --git a/bsp/beaglebone/SConstruct b/bsp/beaglebone/SConstruct
index e9eceb553..01c27a83f 100644
