about M1 MacOS X compilation guidelines

[nomar500]

Hi,

(compilation newbie, here)

On my M1 mac, I've been trying to compile dcamprof

Here's what I came up with (note my non-existant knowledge about compilation flags in general and about M1 arm64 compilation subtleties in particular).

export CC="$(which clang)"
export CPPFLAGS="$CPPFLAGS -Xpreprocessor -fopenmp"
export CFLAGS="-Wall -std=c99 -g -O2 -D_XOPEN_SOURCE=600 -D__EXTENSIONS__ -fopenmp"
export CFLAGS="$CFLAGS -I$(brew --prefix libomp)/include -I$(brew --prefix little-cms2)/include -I$(brew --prefix libtiff)/include $OPTFLAGS"
export LDFLAGS="$LDFLAGS -Wl,-rpath,$(brew --prefix libomp)/lib -L$(brew --prefix libomp)/lib -lomp -L$(brew --prefix little-cms2)/lib -llcms2 -L$(brew --prefix libtiff)/lib -ltiff"

then, from inside the dcamprof/src folder, where the Makefile lies, I:

• comment out the same flags I’ve just exported in bash,
• run make

unfold sample output

Had to adapt the previously mentioned exports.
