mosml2.10.1 - Caml Light won't run on this architecture.

[fandersengalois]

When trying to install mosml (2.00, 2.01, or 2.10.1) macOS Big Sur 11.2.2 from sources, I get:

make world

cd config; /Applications/Xcode.app/Contents/Developer/usr/bin/make all

sh autoconf gcc

Checking the sizes of integers and pointers...

This architecture seems to be neither 32 bits nor 64 bits.

Caml Light won't run on this architecture.

make[1]: *** [runtime] Error 2

make: *** [world] Error 2

This is a false warning - I believe some path in src/Makefile.inc needs to be set to avoid this. This is what I have, but I haven’t checked recently whether it works (I’m on MacOS Catalina), will to try get time over the weekend: # For MacOS X, use: # ----------------- CPP=/usr/bin/cpp -P -traditional -Dunix -Umsdos STRIP=/usr/bin/strip -S # CC=cc LD=gcc DYNLD=$(LD) -I/sw/include -bundle -flat_namespace -undefined suppress Peter On 11 Jun 2021, at 00.29, Flemming Andersen ***@***.******@***.***>> wrote: When trying to install mosml (2.00, 2.01, or 2.10.1) macOS Big Sur 11.2.2 from sources, I get: make world cd config; /Applications/Xcode.app/Contents/Developer/usr/bin/make all sh autoconf gcc Checking the sizes of integers and pointers...

I did some digging. It is the Mac OS Big Sur cc compiler that has become stricter such that several of the c-programs in: mosml/src/config/auto-aux no longer compile. For instance: - sizes.c now needs #include <stdio.h> But there are many other updates needed to all these c-programs Thx, Flemming On Thu, Jun 10, 2021 at 10:52 PM Peter Sestoft ***@***.***> wrote:

I have just pushed a small change that makes it possible to build (for me at least) mosml on MacOS Catalina and Ubuntu 20.04 (LTS).

I've had this in a private branch that I forgot to push.

[fandersengalois]

I just downloaded the pushed version and successfully built and executed the tests under MacOS Big Sur 11.2.2

The only warning was the below. So I am up running with the latest!

Thanks,
Flemming
