Arch Linux

This package currently installs an old svn revision of this clang tool. So the version you get if you install the clang-tools-extra package in extra is newer.

When trying to modernize a simple c++ program

#include <iostream>
int main() {}

$ clang-modernize main.cpp
I get this error:

hi justinzane,

thanks for noting, but C[XX]FLAGS are read from your /etc/makepkg.conf, so it's up to the user to unsure you have sane values there. If it was just FYI note, then apologies and thanks for posting it here!
Cheers,

Note: cannot use C[XX]FLAGS="-O4" LDFLAGS="-Wl,-plugin,/usr/lib/LLVMgold.so"

@msquared good catch, thanks! updated

can you please remove the -j3 flag as usually this should be defined in /etc/makepkg.conf (MAKEFLAGS)

thanks!

based on clang-svn pkgbuild, I know newer/better pkgbuild method is suggested for svn, but i just quickly hacked this up. If clang-svn does it, i'll apply it here.
