Not working on Melodic + Ubuntu 18.04

[wertig0n]

Tried to follow installation guide, but Sophus isn't cooperating. When I checkout a621ff and then subsequently try to make, I get:

[ 5%] Building CXX object CMakeFiles/Sophus.dir/sophus/so2.cpp.o /home/per/workspace/Sophus/sophus/so2.cpp: In constructor ‘Sophus::SO2::SO2()’: /home/per/workspace/Sophus/sophus/so2.cpp:32:26: error: lvalue required as left operand of assignment unit_complex_.real() = 1.; ^~ /home/per/workspace/Sophus/sophus/so2.cpp:33:26: error: lvalue required as left operand of assignment unit_complex_.imag() = 0.; ^~ CMakeFiles/Sophus.dir/build.make:65: recipe for target 'CMakeFiles/Sophus.dir/sophus/so2.cpp.o' failed make[2]: *** [CMakeFiles/Sophus.dir/sophus/so2.cpp.o] Error 1 CMakeFiles/Makefile2:144: recipe for target 'CMakeFiles/Sophus.dir/all' failed make[1]: *** [CMakeFiles/Sophus.dir/all] Error 2 Makefile:140: recipe for target 'all' failed make: *** [all] Error 2

Trying to build from master is a no-go as well. Relevant information:
