回复： env.Textfile proble m

Hi,
I originally wanted to reproduce the problem in the test project, but I did find another problem, scons is recompiled every time. 
Test code: liruncong/NinJaTest at EnvTextFile (github.com)
However, this problem was not found in my actual project.
The test project uses the gcc toolchain, and my actual project uses the armclang (clang) toolchain.



When ninja is not enabled, it is all recompiled every time you compile. After enabling ninja, the first two executions are all recompiles, and the third start is normal (ninja: no work to do.).
After normal (three times later), modify defineOptsFile as follows, scons (enable ninja) does not recompile, which should be problematic.
defineOptsFile = env.Textfile("build/__define_options.txt", [
     "-DTEST1",
     "-DTEST2"  # new added
])

Not enough information to help you.


What's your scons logic look like for this?

Hi,
The source(env.Textfile second parameter) change did not trigger recompilation when using env.Textfile.
