Dimitry Andric 4fb035a886 multimedia/smpeg: fix incorrect warning suppression flag. ... During an exp-run for llvm 12 (see bug 255570), it turned out that multimedia/smpeg does not build with clang 12.0.0: libtool: compile: c++ -DPACKAGE=\"smpeg\" -DVERSION=\"0.4.4\" -I. -I. -O2 -pipe -Wno-error-narrowing -fstack-protector-strong -fno-strict-aliasing -I/usr/local/include/SDL -I/usr/local/include -D_REENTRANT -D_THREAD_SAFE -DTHREADED_AUDIO -DNDEBUG -I.. -DNOCONTROLS -I.. -I../audio -I../video -fno-exceptions -fno-rtti -c huffmantable.cpp -fPIC -DPIC -o .libs/huffmantable.o warning: unknown -Werror warning specifier: '-Wno-error-narrowing' [-Wunknown-warning-option] In file included from huffmantable.cpp:12: ../MPEGaudio.h:129:7: warning: 'register' storage class specifier is deprecated and incompatible with C++17 [-Wdeprecated-register] register int r=(buffer[bitindex>>3]>>(7-(bitindex&7)))&1; ^~~~~~~~~ ../MPEGaudio.h:135:7: warning: 'register' storage class specifier is deprecated and incompatible with C++17 [-Wdeprecated-register] register unsigned short a; ^~~~~~~~~ huffmantable.cpp:553:8: error: constant expression evaluates to -1 which cannot be narrowed to type 'unsigned int' [-Wc++11-narrowing] { 0, 0-1, 0-1, 0, 0, htd33}, ^~~ huffmantable.cpp:553:8: note: insert an explicit cast to silence this issue { 0, 0-1, 0-1, 0, 0, htd33}, ^~~ [... more of these ...] The Makefile attempts to suppress these warnings by adding -Wno-error-narrowing to CFLAGS, in case clang is used, but this warning suppression flag does not exist. It is called -Wno-c++11-narrowing instead, and the attached patch renames the flag. Approved by: maintainer timeout (2 weeks) PR: 255796 MFH: 2021Q2		2021-05-29 16:08:18 +02:00
