5 years ago I can't reproduce it on OS X 10.13.3 x64 (see https://travis-ci.org/ivmai/bdwgc/jobs/489410671 - for master, https://travis-ci.org/ivmai/bdwgc/jobs/489413946 - for release-8_0 branch)

make: *** No rule to make target `libatomic_ops/src/atomic_ops.c', needed by `atomic_ops.o'. Stop.You need either to unpack libatomic_ops (any version) to the current folder or add extra flag like this: make -f Makefile.direct check CFLAGS_EXTRA=-DGC_BUILTIN_ATOMIC

5 years ago I thought if the compiler supported atomics that the library wasn't needed? Also, does this explain the original error which had to do with the static library?

Correct. configure detects this case and defines GC_BUILTIN_ATOMIC macro automatically if the built-in atomic primitives are supported. If you use an alternate build script (e.g. Makefile.direct), the automatic detection is not supported. That's why you should ether have libatomic_ops source o pass -D GC_BUILTIN_ATOMIC to CFLAGS.
Also, does this explain the original error which had to do with the static library? No. If Makefile.direct works then something is wrong with autotools or configure.ac (or Makefile.am) I think.
I don't know the root cause of the failure and I can't reproduce it, so you are the best person who could figure it out (and, ideally, make a fix).
FrankC01
commented
5 years ago OK, I will see if I can get Makefile.direct going as per your prescription.
As far as root cause, I will do what I can but I need to get into the world of autoconf and ./configure (a totally foreign area I've never needed to focus on).

5 years ago Update: I was able to get Makfile.direct working:
AR LD and RANLIB to LLVM alternatives: llvm-ar, llvm-ldd and llvm-ranlib respectively make -f Makefile.direct clean && make -f Makefile.direct check./setjmp_test
This appears to be a X86_64 running DARWIN
Stack appears to grow down, which is the default.
A good guess for STACKBOTTOM on this machine is 0xef098000.
Note that this may vary between machines of ostensibly
the same architecture (e.g. Sun 3/50s and 3/80s).
On many machines the value is not fixed.
A good guess for ALIGNMENT on this machine is 8.
The following is a very dubious test of one root marking strategy.
Results may not be accurate/useful:
Setjmp-based register marking code may work.
Some GC internal configuration stuff:
WORDSZ = 64, ALIGNMENT = 8, GC_GRANULE_BYTES = 16
Using one mark bit per granule.

5 years ago OK but this is a workaround of the reported issue, not a fix. So I leave this issue open.
FrankC01
commented
5 years ago It certainly is and I agree with keeping it open. But the system state that required the workaround is something (hopefully) detectable and incorporated into a fix. As I have the time I am looking into autoconf and configure to make it a fix.

5 years ago Another update in investigation. I've overcome the 'can't find symbol...' with the following:
./configure --enable-static --disable-shared AR=llvm-ar RANLIB=llvm-ranlib
However, with make check when it goes to link the test, it is showing:
libtool: link: gcc -fexceptions -Wall -Wextra -Wpedantic -Wno-long-long -g -O2 -fno-strict-aliasing -o cordtest cord/tests/cordtest.o ./.libs/libgc.a ./.libs/libcord.a /Users/mymachine/Downloads/gc-8.0.2/.libs/libgc.a -lpthread
duplicate symbol _GC_block_was_dirty in:
./.libs/libgc.a(mark.o)
/Users/mymachinei/Downloads/gc-8.0.2/.libs/libgc.a(mark.o)And so on for about 290 symbols. Note that the libgc.a is represented twice in the link and if I remove one of them, as you would expect, it links OK.
I'm not sure to where to look to see why the static library is added twice to the link line.

5 years ago What's the current folder? I don't understand why 2 libgc.a files were created. (Have you run "make clean"?)
FrankC01
commented
5 years ago The current folder is either ~/bdwgc or ~/Downloads/gc-8.0.2 (same issues). There are not 2 libgc.a files, just that from the make it is including it twice with a relative and fully qualified statement.

I reproduced it (libgc.a specified twice) on Cygwin. I don't understand the reason though.
