/usr/local/clang7 is likely a better place to look. Check out 
Appendix C.3 of the R Inst.&Adm. manual:

https://cran.r-project.org/doc/manuals/r-release/R-admin.html#macOS

That's better! After correcting some obvious(?) errors(?) in that 
page, ./configure run without errors! (Had only read 
mac.r-procject.org/tools/ so far).

Can you report these "obvious(?) errors(?)" so they can be fixed?

As I promised, a report will come. Probably later today.

Best, G?ran

Best,
Uwe

After a night's sleep I will 'make'. I'll report back to r-sig-mac.

Thanks, G?ran

Update: There is a libgcc_s.1.dylib in /usr/lib, as a symlink to 
/usr/lib/libSystem.B.dylib. Is that one useful?

Thanks Peter,
The tripping lines are here

configure:24616: gcc -o conftest -g -O2 -I/usr/local/include 
-L/usr/local/lib conftest.c -ldl -lm? >\

dyld: Library not loaded: /usr/local/lib/libgcc_s.1.dylib
?? Referenced from: /Users/gb/R/src/R-devel/./conftest

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

gobr0002 at MBP-2:~/R/src/R-devel$ ./configure

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:

configure:23748: checking for size_t
configure:23748: gcc -c -g -O2 -I/usr/local/include conftest.c >&5
configure:23748: $? = 0
configure:23748: gcc -c -g -O2 -I/usr/local/include conftest.c >&5
conftest.c: In function 'main':
conftest.c:116:21: error: expected expression before ')' token
if (sizeof ((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, G?ran
