Projects linked to libfmt.so.6.0.0 are broken when they try to load libfmt.so.6.1.1 due to the missing symbol: _ZN3fmt2v68internal14sprintf_formatIdEEPcT_RNS1_6bufferIcEENS1_13sprintf_specsE

See e.g. https://bugs.archlinux.org/task/64802

I've reintroduced sprintf_format in ae7c501 to restore the ABI compatiblity:

$ nm -gU  libfmt.6.dylib  | grep sprintf
0000000000002130 T __ZN3fmt2v68internal14sprintf_formatIdEEPcT_RNS1_6bufferIcEENS1_13sprintf_specsE
0000000000002430 T __ZN3fmt2v68internal14sprintf_formatIeEEPcT_RNS1_6bufferIcEENS1_13sprintf_specsE

Thanks for reporting!

Thanks, I've confirmed the solution on my end by backporting this patch into our fmt package and locally rebuilding/testing it.

I guess it probably makes sense for you to release a hotfix soon, so that the distros which have already upgraded can get this change automatically.

Thanks for the confirmation. I do plan to release 6.1.2 which will include this and other fixes shortly.

fmt seems to be quite strict about ABI compatibility, see fmtlib/fmt#1471.

Add run_exports (#11)

* Add run_exports

Since fmt is a shared library, we should tell every recipe that builds against it to require a compatible version at runtime.

* MNT: Re-rendered with conda-build 3.19.1, conda-smithy 3.6.15, and conda-forge-pinning 2020.03.24

* Only pin to major version
