  Expected in: dynamic lookup

Configure should pass -latomic when 8-byte atomics is not hardware-supported.

So I can setup the checks correctly, what's your output from:

uname -s
uname -m
barracuda156 commented 1 year ago

@andrjohns Thank you for responding!

36-171% uname -s
Darwin
36-171% uname -m
Power Macintosh
36-171% uname -p
powerpc
barracuda156 commented 1 year ago

P. S. I have seen elsewhere that arm32 and mips also require -latomic, but cannot verify that personally. I assume i386 would need it too, at least with GCC. But my personal concern is just ppc (= ppc32).

andrjohns commented 1 year ago

Can you try this branch: https://github.com/andrjohns/QuickJSR/tree/ppc-32bit

barracuda156 commented 1 year ago

Yes, that works perfectly fine, the flag is passed, installation succeeds.

Merged the fix to main

charles-plessy commented 10 months ago

It looks like the fix may also be needed on some 32-bit ARM platforms: see what happens on Debian's armel port.

barracuda156 commented 10 months ago

@charles-plessy The proper solution would be a test for support of 8-byte atomics without libatomic and then a conditional dependency. This would fix 32-bit arm, mips and Rosetta (where uname will have Intel, not PowerPC). I do not really know however how to implement such test outside of CMake build system.

andrjohns commented 10 months ago

@charles-plessy CRAN version updated to always link to libatomic on 32-bit distros

barracuda156 commented 10 months ago

P. S. I not sure how this gonna work with Clang on i386, but perhaps it is not a big concern. For powerpc that was never an issue since at least on Darwin we are sure that the compiler is GCC, and GCC always gonna have libatomic. Clang does not have it, but uses compiler-rt library (well, I guess so). I cannot test at the moment whether the linker dismisses the flag or the build gonna fail due to a missing lib.

charles-plessy commented 9 months ago

Thanks! The new release solved the problem on our side :)

ryandesign commented 4 months ago

I not sure how this gonna work with Clang on i386

It causes build failure:

ld: library not found for -latomic
clang: error: linker command failed with exit code 1 (use -v to see invocation)
barracuda156 commented 4 months ago

@ryandesign @andrjohns It should probably be restricted to GCC. (arm32 issue on Debian used gcc, from the log.)

I am not sure if Clang can use libatomic in principle, but it is probably something rather exotic if possible at all.

andrjohns commented 4 months ago

@ryandesign @barracuda156 Can you let me know if this branch fixes things: https://github.com/andrjohns/QuickJSR/tree/clang32-atomics

barracuda156 commented 4 months ago

@andrjohns Applying 5393e43bb5ccac8e41e19e976fe5baa9e4cd892f patch onto 1.1.3 does not work for a build with GCC, -latomic does not get passed and linking fails. Should I pick something else too?

andrjohns commented 4 months ago

Can you post the full build log with the failure?

barracuda156 commented 4 months ago

@andrjohns Sure:
