I have machine with 32GiB RAM, so I don't think that RAM shortage might
be an issue.
VTK ( https://vtk.org/download/) version 8.2.0
I just copied existing vtk-8.1.0 ebuild to vtk-8.2.0.ebuild
and emerged that. It doesn't go far outside vanilla stuff, it pretty
much does what I'd do when compiling manuallly.
Emerge with ordinary "-march=native -O3 pipe" CFLAGS works fine.
But when I try to compile it with LTO flags:
CFLAGS="-march=native -pipe -O3 -flto=1 -ffat-lto-objects -pipe
-fuse-linker-plugin -fno-delete-null-pointer-checks"
CXXFLAGS="${CFLAGS} -fpermissive"
LDFLAGS="-Wl,-O3 -Wl,--sort-common -Wl,-flto=1 -Wl,--as-needed
-ffat-lto-objects -fno-delete-null-pointer-checks"
it fails with:
