QuickJSR 1.8.0 undefined atomic_fetch_add symbol with Rv4.5.0

[sfishback]

I cannot figure out why this module will not install on R v4.5.0 with gcc v12.2.0 on rhel9.

$ R CMD INSTALL QuickJSR_1.8.0.tar.gz

When I manually compile the code works fine. And the atomic_fetch_add symbol is there.

$ nm QuickJSR.so | \grep atomic_fetch

U atomic_fetch_or
U atomic_fetch_sub
U atomic_fetch_xor

Hmm very odd. I've just added RHEL9 to the CI and it all builds and passes tests without issue, so I think it might a configuration issue or something else system-specific: https://github.com/andrjohns/QuickJSR/actions/runs/16495175725/job/46639078160

Those declarations would be in stdatomic.h, is your compiler able to include it:

echo "#include <stdatomic.h>" | gcc -E -dM -

I've just added RHEL9 to the CI and it all builds and passes tests without issue, so I think it might a configuration issue or something else system-specific: https://github.com/andrjohns/QuickJSR/actions/runs/16495175725/job/46639078160 Those declarations would be in stdatomic.h, is your compiler able to include it: echo "#include <stdatomic.h>" | gcc -E -dM - - Reply to this email directly, view it on GitHub<#89 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/AAOK2EIOWKFM7RQBWNJIW3D3KDAIJAVCNFSM6AAAAACCEAZM4GVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZTCMJTGEYTIOBQGE>.
