I am building kodi on Arch ARM for Raspberry Pi2 (armv7h) with the following this cmake stanza. It works but it throws tons of warnings about conflicting switches. For example:
Code:
/scratch-nfs/PKGBUILDs/alarm/kodi-rbp/src/xbmc-17.3-Krypton/xbmc/profiles/ProfilesManager.cpp:1:0: warning: switch -mcpu=cortex-a7 conflicts with -march=armv7-a switch
...
/scratch-nfs/PKGBUILDs/alarm/kodi-rbp/src/xbmc-17.3-Krypton/xbmc/interfaces/legacy/WindowXML.cpp:1:0: warning: switch -mcpu=cortex-a7 conflicts with -march=armv7-a switch
The CFLAGS and CXXFLAGS are the distro default. Should I adjust the -DWITH_CPU flag to something else? The resulting package should run on both RPi2 and RPi3. Thanks.
Code:
export CFLAGS="-march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 -O2 -pipe -fstack-protector --param=ssp-buffer-size=4"
export CXXFLAGS="-march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 -O2 -pipe -fstack-protector --param=ssp-buffer-size=4"
