I've tried that and compiled my git version of darktable now in the following way:
cd build cmake -DBINARY_PACKAGE_BUILD:BOOL=ON -DCMAKE_BUILD_TYPE=Release .. make sudo make install And that works, thanks! I compared now the two in different ways compiled variants that are working for me: The first with the editing of the CMakeList.txt, setting the flags -march=corei7-avx and -mtune=native and using the build.sh script and the second variant building with cmake and the option BINARY_PACKAGE_BUILD:BOOL=ON (which produced no -march flag but the flag -mtune=generic) Both variants of the compiled darktable are working good and at the same speed, so everything is ok. Why i've got the problem with the -march=native flag, maybe that my kernel is to old and does not detect my processor type exactly right. kernel 3.13.0-29-generic <--> Intel(R) Core(TM) i7-4765T Rico Am 20.06.2014 17:03, schrieb johannes hanika: > my cmake literacy is very limited, but you can abuse the > > BINARY_PACKAGE_BUILD:BOOL=OFF > > option (pass -D[..]=on to cmake when configuring). this is used for > redistributable binaries and will not use the -march=. flag. > > other than that i was under the impression that > > CFLAGS=<your flags> cmake > > would pick up the env var (note that most of dt is actually c and not c++). > not sure which one would be used then, the -march would still be added to > the flags by us. > > cheers, > jo > ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
