Hello, I am trying to compile a C++ code using quite a lot of template with OpenMP 4 for an nvptx target using gcc 9.1.0. My gcc is able to compile a simpler C example and it runs on my GPU (very slowly, but maybe sm_35 is not well supported). The C++ code does compile, but the linker step says: ----------- lto1: fatal error: LTO_tags out of range: Range is 0 to 420, value is 1006632960 compilation terminated. mkoffload: fatal error: /home/kelling/checkout/spack/spack/opt/spack/linux- ubuntu18.04-x86_64/gcc-7.3.0/gcc-9.1.0-pm7tbe6qnpyngd73674kyj3z27ybidht/bin/ x86_64-pc-linux-gnu-accel-nvptx-none-gcc returned 1 exit status compilation terminated. lto-wrapper: fatal error: /home/kelling/checkout/spack/spack/opt/spack/linux- ubuntu18.04-x86_64/gcc-7.3.0/gcc-9.1.0-pm7tbe6qnpyngd73674kyj3z27ybidht/ libexec/gcc/x86_64-pc-linux-gnu/9.1.0//accel/nvptx-none/mkoffload returned 1 exit status compilation terminated. /usr/bin/ld: error: lto-wrapper failed collect2: error: ld returned 1 exit status ----------- My invocation of g++ looks like this: g++ -DDEFINES -Iincludes \ -foffload=nvptx-none -foffload=-lm -fopenmp \ -std=gnu++11 -o main main.cpp Google did not find that error message. Does anyone have a hint what this is about?
