| Subject: | Compilation failure (with newer c++ compilers) |
On newer systems (debian 10, ubuntu 18.04, fedora 28, freebsd 12+13) the compilation fails. On freebsd systems (clang++) it looks like this:
...
c++ -O3 -fPIC -fexceptions -fvisibility=hidden -Wno-ctor-dtor-privacy -D__ANSI__ -I. -ISource -ISource/Metadata -ISource/FreeImageToolkit -ISource/LibJPEG -ISource/LibPNG -ISource/LibTIFF4 -ISource/ZLib -ISource/LibOpenJPEG -ISource/OpenEXR -ISource/OpenEXR/Half -ISource/OpenEXR/Iex -ISource/OpenEXR/IlmImf -ISource/OpenEXR/IlmThread -ISource/OpenEXR/Imath -ISource/OpenEXR/IexMath -ISource/LibRawLite -ISource/LibRawLite/dcraw -ISource/LibRawLite/internal -ISource/LibRawLite/libraw -ISource/LibRawLite/src -ISource/LibWebP -ISource/LibJXR -ISource/LibJXR/common/include -ISource/LibJXR/image/sys -ISource/LibJXR/jxrgluelib -c Source/LibRawLite/./src/libraw_cxx.cpp -o Source/LibRawLite/./src/libraw_cxx.o
