Thanks Peter,
The tripping lines are here
configure:24611: checking size of size_t
configure:24616: gcc -o conftest -g -O2 -I/usr/local/include
-L/usr/local/lib conftest.c -ldl -lm >\
&5
configure:24616: $? = 0
configure:24616: ./conftest
dyld: Library not loaded: /usr/local/lib/libgcc_s.1.dylib
Referenced from: /Users/gb/R/src/R-devel/./conftest
Reason: image not found
so it seems as if my installation of tools is lacking an essential part
(/usr/local/lib/libgcc_s.1.dylib). I'll look around, but any suggestion
is welcome!

I can't claim to understand this, but on my system of same age, using system clang,
configure does complete. It does get that error on line 23748, but that, and several
similar subsequent tests just end up returning "yes".
configure:23748: checking for size_t
configure:23748: gcc -arch x86_64 -c -g -O2 -I/usr/local/include conftest.c >&5
configure:23748: $? = 0
configure:23748: gcc -arch x86_64 -c -g -O2 -I/usr/local/include conftest.c >&5
conftest.c:118:21: error: expected expression
if (sizeof ((size_t)))
^
1 error generated.
[..snip..]
configure:23748: result: yes
(as usual, configure code is nigh on unreadable, but I think the logic is that the size_t type
exists if you can do "sizeof (size_t)", but not "sizeof ((size_t))", so the
error is expected.)
The line that trips you up comes later:
configure:24611: checking size of size_t
configure:24616: gcc -arch x86_64 -o conftest -g -O2 -I/usr/local/include
-L/usr/
local/lib conftest.c -ldl -lm >&5
configure:24616: $? = 0
configure:24616: ./conftest
configure:24616: $? = 0
configure:24630: result: 8
so that is where you should look for clues (or at least tell us what it says
there).

Hello,
I'm (for the first time) trying to build R-devel from source (to be able to
check my CRAN packages on a Mac), but it breaks already after

with
checking size of size_t... configure: error: in `/Users/gb/R/src/R-devel':
configure: error: cannot compute sizeof (size_t)
See `config.log' for more details
Some 'details' regarding size_t:

My MacBook Pro is old (2010), so I am stuck with MacOS 10.13.6, XCode 10.1. I'm
using clang 7.0.0 and fortran 6.1.0.
Do I need to buy a new Mac?
Thanks, Göran
