Build error verilator

[Mixermachine]

Hy there,

I completed the git clone and RISC-V front-end install to /usr/local/
After

./configure --with-riscv=/usr/local
make

I get

g++  -I.  -MMD -I/usr/local/share/verilator/include -I/usr/local/share/verilator/include/vltstd -DVL_PRINTF=printf -DVM_COVERAGE=0 -DVM_SC=0 -DVM_TRACE=0 -faligned-new -Wno-bool-operation -Wno-sign-compare -Wno-uninitialized -Wno-unused-but-set-variable -Wno-unused-parameter -Wno-unused-variable -Wno-shadow     -O1 -std=c++11  -g -I/home/e6430/risc-v/riscv-sodor/emulator/common -I/usr/local/include -I/home/e6430/risc-v/riscv-sodor/riscv-fesvr/fesvr  -L/usr/local/lib -Wl,-rpath,/usr/local/lib -L. -lpthread -DVERILATOR -include /home/e6430/risc-v/riscv-sodor/emulator/common/verilator.h   -c -o emulator.o /home/e6430/risc-v/riscv-sodor/emulator/common/emulator.cpp

My setup:
Kubuntu 18.10

verilator --version
Verilator 3.922 2018-03-17 rev UNKNOWN_REV

Has anybody seen this error before?
Might be the Verilator version?

Verilator was installed via
sudo apt install pkg-config verilator

I believe this is a duplicate of issue #37. It should be addressed by PR #42. I'll close it when the latter PR is accepted.
