[Pkg-alsa-devel] Bug#837590: alsa-tools FTBFS on armel: gcc-6 narrowing conversions

[Helmut Grohne]

Source: alsa-tools
Version: 1.1.0-1
Severity: serious

I noticed that alsa-tools fails to cross build from source for armel due
to gcc-6 narrowing conversion issues. Issues about narrowing conversions
are generally not cross compilation specific and reproducible natively.
Thus filing at RC severity. A full (cross) build log is attached. The
relevant excerpt is:

| arm-linux-gnueabi-g++ -DPACKAGE_NAME=\"hdspmixer\" -DPACKAGE_TARNAME=\"hdspmixer\" -DPACKAGE_VERSION=\"1.11\" -DPACKAGE_STRING=\"hdspmixer\ 1.11\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DPACKAGE=\"hdspmixer\" -DVERSION=\"1.11\" -DSTDC_HEADERS=1 -DHAVE_LIBASOUND=1 -I.   -Wdate-time -D_FORTIFY_SOURCE=2  -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security   -I/usr/include/freetype2   -D_THREAD_SAFE -D_REENTRANT -fno-exceptions -MT channelmap.o -MD -MP -MF .deps/channelmap.Tpo -c -o channelmap.o channelmap.cxx
| channelmap.cxx:59:1: error: narrowing conversion of '-1' from 'int' to 'char' inside { } [-Wnarrowing]
|  };
