Yes, using xcrun for the SDKVERSION was one change.
Also, I use subfolders under /Applications/. Notably, I have XCode installed
in /Applications/Development/, so I’ve added:
XCODE_PATH=`xcode-select --print-path`
and changed:
MACSDKDIR="${XCODE_PATH}/Platforms/MacOSX.platform/Developer/SDKs/MacOSX${SDKVERSION}.sdk"
I think there’s an xcrun option that will provide the above path w/o having to
use the double var concatenation.
And:
PROCESSNUM=$(sysctl hw.ncpu | sed 's/^.*://' | sed 's/[^[:digit:]]//g’);
I have a feeling ‘sysctl’ may be more future-proof than the output of hostinfo.
Seems cleaner at least.
Another is for anything using cmake and CMakeModules/FindOpenMP.cmake for
libomp, add:
#Apple clang
"-Xpreprocessor -fopenmp -lomp”
(-lomp may not be necessary?)
I can use homebrew’s clang instead, but if that was the only reason for not
using Apple’s clang, that may be a solution. (I haven’t gotten a working build
yet, though, so...)
BTW, the only libiconv that I got to work without error was homebrew’s, so I
was thinking they’re building it with particular options. Are you able to get
it to link in and/or compile correctly? I was getting this error until I
installed homebrew’s version:
ld: warning: dylib
(/Users/rsc/src/hugin-2020.0.0-2/mac/ExternalPrograms/repository/lib/libiconv.dylib)
was built for newer macOS version (10.15) than being linked (10.13)
Undefined symbols for architecture x86_64:
"_iconv", referenced from:
Exiv2::
- Completely aside, when I ran into the above error (x86_64), I tried updating
the line:
OPTIMIZE="-march=core2 -mtune=core2 -ftree-vectorize” \
to a more current -march, but couldn't really find anything definitive to use
and nothing I tried helped anyway. But that might be something to consider as
well - core2 macs were deprecated quite a while ago (I had a white imac that
was core2 - I don’t think any of the silver ones are). So what might be a
better -march to optimize for?
Thanks for the updates! I assume I need to refresh hugin from hg?
