Bug ID: 87161
Summary: if -Werror appear after -Wmissing-prototypes the
warning is not turn into error
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nir.aizik at harman dot com
Target Milestone: ---
Werror before Wmissing-prototypes gives:
g++ -c -Werror -Wmissing-prototypes test.c -o test.o
cc1plus: error: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC
but not for C++ [-Werror]
cc1plus: all warnings being treated as errors
Werror after Wmissing-prototypes gives:
g++ -c -Wmissing-prototypes -Werror test.c -o test.o
cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for
C/ObjC but not for C++
I believe both options should end with error or at least this behavior should
be documented
