scons: overriding build options for one file
- by Jason S
Easy question but I don't know the answer.
Let's say I have a scons build where my CCFLAGS includes -O1. I have one file needsOptimization.cpp where I would like to override the -O1 with -O2 instead. How could I do this in scons?
update: this is what I ended up doing based on bialix's answer:
in my SConscript file:
Import('env');
env2 = env.Clone();
env2.Append(CCFLAGS=Split('-O2 --asm_listing'));
sourceFiles = ['main.cpp','pwm3phase.cpp'];
sourceFiles2 = ['serialencoder.cpp','uartTestObject.cpp'];
objectFiles = [];
objectFiles.append(env.Object(sourceFiles));
objectFiles.append(env2.Object(sourceFiles2));
...
previously this file was:
Import('env');
sourceFiles = ['main.cpp','pwm3phase.cpp','serialencoder.cpp','uartTestObject.cpp'];
objectFiles = env.Object(sourceFiles);
...
