I have tried to compile openEMS-v0.0.33-rc1 source code on ubuntu 14.04 and I got the # error "SSE instruction set not enabled".
Some information obtained from the log file are shown below. Please help me figure out how to solve this error.

I have tried to compile openEMS-v0.0.33-rc1 source code

That is a very old version. Please try the latest v0.0.34

SSE instruction set not enabled

Do you compile on a 64bit or 32bit Ubuntu?
I do not support 32bit any more... if you still have a 32bit OS, you may need to set some additional compiler flags.
Your CPU has to have SSE support of course...

Thank you Thorsten for your reply. This problem has been solved by adding

Code: Select all

 set(CMAKE_CXX_FLAGS "-msse -march=native") 

at line 144 in CMakeLists.txt.

I think that my problem is same as the one described in http://openems.de/forum/viewtopic.php?f=2&t=332.

Best Regards
