hello
in my sources, i have both C and C++ files. Something like
my_lib_la_SOURCES = foo.c foo.cpp
I want to pass, for example, -Wdeclaration-after-statement to gcc.
Hence,
when compiling foo.cpp, i have the warning :
cc1plus.exe: warning: command line option
'-Wdeclaration-after-statement'
is valid for C/ObjC but not for C++
How can I remove this warning when compiling c++ files ?
thank you

I misread - for C and not C++ you should set "CFLAGS"
./configure CFLAGS="-g -O2 -Wdeclaration-after-statement" CXXFLAGS="-g
-O2"
it will still not work as $(CFLAGS) will be passed to the compilation
of the c++ source file

Are you saying you've tried it?
1) yes i tried it
2) the fact that I have the warning proves that CFLAGS is passed to
the C++ compiler...

That's not my understanding of how Automake
(or GNU Make) works. Unless the project has overridden the default
use for these variables, that's how it's supposed to work, and
this problem is an example of why.
This is the relevant section of the manual:
