I'm trying to load a library that includes some C++ code. It requires libstdc++.so.6 which is looking for __strftime_l. $ nm -D /usr/rx30/musl/lib/libstdc++.so.6 | grep __strftime_l U __strftime_l $ I get the following error when trying to load libstdc++.so.6. Error relocating /usr/rx30/musl/lib/libstdc++.so.6: __strftime_l: symbol not found On Wed, May 8, 2019 at 12:26 PM John Mudd <johnbmudd@...il.com> wrote: > Hi, I'm upgrading my musl from 1.19 to 1.22 but it looks like I lost > the __strftime_l function.
