Error when parsing precompiled header：macro expansion producing 'defined' has undefined behavior [-Wexpansion-to-defined]

[JinZhuHuang]

My code includes some macro expand to "defined", then fauxpas make the following error message:

Error when parsing precompiled header：macro expansion producing 'defined' has undefined behavior [-Wexpansion-to-defined].

I have tried calling fauxpas using params as below: --extraCompilerArgs OTHER_CFLAGS="-Wno-expansion-to-defined"

but then fauxpas failed to check codes. What is the right way to add compiler arguments like -Wno-expansion-to-defined?

Thanks for reporting this.

Can you please verify whether this issue persists for you with the latest version (1.7.1) ?

When using the --extraCompilerArgs option, insert the compiler flag directly there, like this:

-Wno-expansion-to-defined

not like this:

OTHER_CFLAGS="-Wno-expansion-to-defined"

[JinZhuHuang]

When using like this： --extraCompilerArgs -Wno-expansion-to-defined

The following errors：

Argument error: ERROR: Argument --extraCompilerArgs needs a value Argument error: ERROR: Unknown argument: -Wno-expansion-to-defined Determining build settings for 2 targets and 2 build configurations

I figured out the correct syntax it should be --extraCompilerArgs \-Wno-expansion-to-defined

No, it's wrong. -c <configuration file> is the only way for it to work.
