@mattf, you can just patch it yourself in the PKGBUILD until the BoringSSL patch gets fixed by lexiforest.

Here's a patch to your repo with my suggestion:

Unfortunately this alone won't make curl-impersonate-chrome compile, at least in my machine. Later I get a configure error while it tries to build cURL:

configure:4998: gcc   -lc++ conftest.c -pthread -lc++ >&5
/usr/bin/ld: cannot find -lc++: No such file or directory
configure:5050: error: C compiler cannot create executables

@simona There is an issue open in upstream about that: https://github.com/lexiforest/curl-impersonate/issues/81

I don't know if there is any proper workaround that could be done here. Let me know if you have suggestions.

Note: The following makedeps are in base or base-devel, and thus shouldn't be specified: autoconf, automake, gcc, patch, tar

Also getting the error about ignored-attributes. The trick with "CXXFLAGS="-Wno-error=ignored-attributes -g -O2" make chrome-build" did not change anything for me (added the CXXFLAGS part before "make chrome-build" in PKGBUILD).

Build fails because of a warning. I fixed it by editing PKGBUILD to ignore my specific warning: CXXFLAGS="-Wno-error=ignored-attributes -g -O2" make chrome-build. Might be a good idea to set CXXFLAGS="-Wno-error" and ignore all warnings because they can change with compiler version (see https://embeddedartistry.com/blog/2017/05/22/werror-is-not-your-friend/).

@somini Do you have that when trying to directly from source: https://github.com/lwthiker/curl-impersonate/blob/main/INSTALL.md#native-build ?

It could have to do with the default buildflags makepkg is using but this pkgbuild already has options=("!buildflags") so I'm not sure.
