Arch Linux User Repository

rr should no longer need the python2 dependency (via python2-pexpect). It's the only thing left on my system keeping python2 installed.

Hi @Amanieu: while that could certainly be added to the PKGBUILD, it isn't entirely clear to me that this is the right thing to do: generally, one would modify the options=() via makepkg.conf to adjust behavior on one's own system.

Is there some reason librrprepload.so should be treated specially?

Can you add options=(!strip) so that we can get proper backtraces from librrpreload.so?

Getting:

Missing dependency lib32-gcc-libs

for the cross-compile-toolchain

Here's a patch that fixes a bunch of build/install issues with the pkgbuild:

(right now it fails to build, and then fails to install on current archlinux. please apply this fix)

Looks like it was fixed upstream: https://github.com/mozilla/rr/issues/2237

I'm getting the following build error:

For those who don't want the bit version or don't have the cross compiling tool chain:

add -Ddisable32bit=ON on line 24 in PKGBUILD.
