https://sourceforge.net/projects/brlcad/ brief overview
latest version as of 2018-02-05 is 7.26.4 (2017-10-15) available at https://sourceforge.net/projects/brlcad/files/BRL-CAD%20for%20Linux/
http://brlcad.org/wiki/Building_from_SVN current revision 70666
svn checkout https://svn.code.sf.net/p/brlcad/code/brlcad/trunk brlcad
dependances to compile on Mageia :
- cmake
- check pre-requisites (apparently not needed) : urpmi lib64xi6-static-devel lib64xext6-static-devel lib64x11_6-static-devel lib64xau6-static-devel lib64xdmcp6-static-devel
mkdir brlcad-build cd brlcad-build cmake ../brlcad # takes 1 min 23 sec o_O quite fast make # actual build 16h52 ETA +25 min hence 17h17 80% at 17h32... 90% at 17h36 95% at 17h40 make test # should report successful, Total Test time (real) = 182.33 sec make benchmark # to test benchmark, may be better using option for cmake -DBRLCAD_FLAGS_OPTIMIZATION=ON
I'm compiling on my Asus Zenbook UX305 with 8 GB RAM & a CPU model name: Intel(R) Processor 5Y10 CPU @ 0.80GHz
Minimum run time is 3 minutes, 12 seconds
Maximum run time is 30 minutes
Estimated time is 9 minutes, 36 seconds
Benchmark

After cmake cmake ../brlcad -DBRLCAD_FLAGS_OPTIMIZATION=ON
not that much better:
