OK, currently it looks like only the versions built on the OS X 10.7
system are portable across versions.
For future reference you should be able to build on an OS X 10.10 system
with the following options:
for a 32-bit version built on a 64-bit system:
cc -c -O2 -m32 usleep.c
cc -c -O2 -m32 asd1.c
gfortran -o kvasd_1.12_mac32 -O2 -m32 -mmacosx-version-min=10.7 \
-Wl,-headerpad_max_install_names kvasd.f90 asd1.o usleep.o
and for a 64-bit version:
cc -c -O2 usleep.c
cc -c -O2 asd1.c
gfortran -o kvasd_1.12_mac64 -O2 -mmacosx-version-min=10.7 \
-Wl,-headerpad_max_install_names kvasd.f90 asd1.o usleep.o
The -headerpad_max_install_names ensures that the executable has enough
room in the section where the shared library linking path references go,
which we need as we have to re-write them to reference the same shared
libraries that we bundle with WSJT-X using a relative path. Not an issue
as it stands since the references created on John's system are longer
than the re-written ones but it is good practice to pad them just in case.
I would expect '-O2' at least to be passed to each compile for a release
build, I'm not sure why only the asd1.c file is optimized (I assume it
is the bulk of the code but I would still turn on optimization for
everything else).
I think we have versions that are suitable for general release so no
need to rebuild at the moment but if that need does arise the above
should save some time by only building on one version of OS X i.e. 10.10.
