macos - 使用自制软件安装 gnupg2 依赖 libusb 时出错

Question

我在 mac osx 上使用自制软件安装 gnupg2 并在安装依赖项 libusb 时出错。

brew install gpg2

……

==> Installing gnupg2 dependency: libusb
==> Downloading http://downloads.sourceforge.net/project/libusb/libusb-1.0/libusb-1.0.9/libusb-1.0.9.tar.bz2
Already downloaded: /Library/Caches/Homebrew/libusb-1.0.9.tar.bz2
==> ./configure --prefix=/usr/local/Cellar/libusb/1.0.9
==> make install
os/darwin_usb.c:1749: error: old-style parameter declarations in prototyped function definition
os/darwin_usb.c:1749: error: expected '{' at end of input
make[1]: *** [libusb_1_0_la-darwin_usb.lo] Error 1
make[1]: *** Waiting for unfinished jobs....

任何想法如何解决这一问题？

Had the same problem, fixed it by installing the XCode command line tools (previously was using gcc standalone package)
