#297 [FTBS] xfe v2.0.1 on openSUSE Leap 15.6

[J G Miller]

When building xfe v2.0.1 on openSUSE Leap 15.6 with gcc-13, compilation fails with

depbase=`echo main.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
_ /usr/bin/g++-13 -DLOCALEDIR=\"/usr/local/share/locale\" -DHAVE_CONFIG_H -I. -I..  -I. -I.. -I../intl -I/usr/local/include/freetype2 -I/usr/local/include/harfbuzz -I/usr/local/include -I/usr/include/libpng16 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/local/include/freetype2 -I/usr/local/include/harfbuzz -I/usr/local/include -I/usr/include/libpng16 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include   -O2 -Wall -std=c++11 -O3 -fPIC -mtune=native -I/usr/local/include/fox-1.6 -DHAVE_XFT_H -DHAVE_XRANDR_H=1 -DSTARTUP_NOTIFICATION -MT main.o -MD -MP -MF $depbase.Tpo -c -o main.o main.cpp &&\

      |                                                                         ^~~~~~~~~~

If I add -Dlinux to the invocation of gcc-13, then all compiles and links and installs successfully because compilation then includes #if defined(linux) block of code in main.cpp.

So for some reason the configure script is not adding the necessary flag " -Dlinux" to the CFLAGS even though config.log contains instances of

Target: x86_64-suse-linux
build='x86_64-pc-linux-gnu
build_os='linux-gnu'
host='x86_64-pc-linux-gnu'
host_os='linux-gnu'

Even if I do autoreconf -fiv to generate a fresh configure script, the same compilation error occurs.

There is no such issue in Ubuntu 24.04 with gcc 13.3.0 so maybe your issue is related to your OpenSuse Leap system?
