Due to https://github.com/facebook/folly/issues/1800, the update of the AUR package will be paused until build can success.

It would be great if you can update this package to the latest release. I found the latest release fixes the build problem identified by jghodd 1 month ago.

had to fix this by adding a hard cast of (google::logging_fail_func_t) to line 79 of Init.cpp:

    google::InstallFailureFunction((google::logging_fail_func_t)abort);

thus far, it seems that hard coding the path into FindLibDwarf.cmake is working, but should not be the real solution.

./CMake/FindLibDwarf.cmake:  set(LIBDWARF_INCLUDE_DIRS "/usr/include/libdwarf/libdwarf-0")

the issue is that DW_SECT_INFO, DW_SECT_ABBREV and DW_SECT_STR_OFFSETS are only defined in /usr/include/libdwarf/libdwarf-0/dwarf.h

getting a build error:

as far as I can tell, the cmake FindLibDwarf.cmake is finding the wrong path to dwarf.h - there are multiples:

/usr/include/lldb/Core/dwarf.h
/usr/include/libdwarf/libdwarf-0/dwarf.h
/usr/include/dwarf.h

the one we want is /usr/include/libdwarf/libdwarf-0/dwarf.h

There are different pkgrel in .SRCINFO and PKGBUILD:

https://aur.archlinux.org/cgit/aur.git/commit/?h=folly&id=266e859d579e86fef920c0ee7b4fd2aae6f3cc44

This causes yay to reinstall folly on every update.

Some new depends or possibly optdepends seem to be libaio, libunwind, libdwarf, and liburing.

getting a build error with fizz and wangle related to folly

CMake Error in CMakeLists.txt: Imported target "Folly::folly" includes non-existent path

"/include"

• The path was deleted, renamed, or moved to another location.

• An install or uninstall procedure did not complete successfully.

• The installation package was faulty and references files it does not provide.

Waiting for https://github.com/facebook/folly/pull/1439 to be released.
