Mac Catalina编译Emacs 27踩坑

casouri · 2019 年11 月 29 日 21:42

Catalina没了自动装header file的那个安装包，/usr/include也变成只读，直接编译Emacs就会找不到头文件：

emacs/ 吉 > make
...
xml.c:26:10: fatal error: 'libxml/tree.h' file not found
...

解决方法是configure的时候加上include地址：

emacs/ 吉 > gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.0 (clang-1100.0.33.12)
Target: x86_64-apple-darwin19.0.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

这个--with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/就是头文件地址了，找一找libxml，发现在libxml2里。

所以configure这么写：

./configure --with-modules --with-pdumper=yes --oldincludedir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/libxml2/

然后make。

P.S. 大概是我启用了portable dumper，make的时候又有个报错：

Loading /Users/yuan/attic/emacs/lisp/loaddefs.el (source)...
Symbol’s value as variable is void: ctl-x-6-map
make[1]: *** [bootstrap-emacs.pdmp] Error 255
make: *** [src] Error 2

emacs-devel里有个回复说用make bootstrap可以解决。我make bootstrap又出个问题，大概长这样：

emacs: could not load dump file
 "/Applications/Emacs.app/Contents/MacOS/Emacs.pdmp": not built for
 this Emacs executable

我没管，又make一遍，就没问题了……

Catalina 太不稳定了，我升级后窗口频繁切换焦点，根本没法用，只好重装mojave。建议没有升级的伙伴谨慎升级

如果你从 homebrew 安装 pkg-config 的话，可以用这个 patch：pkgconfig_10.15.diff · GitHub

麻烦之处是每次 patch 好，编译完之后最好 revert 掉，否则下次 brew update 的时候会覆盖。

另外这个头文件的改动从上一个版本 Mojave 就有了。

homebrew 相关的讨论这里可以找到，目前看没什么特别好的方法

github.com/Homebrew/brew

pkg-config files on >=10.14 assume headers in /usr/include

As the release note of Xcode 10, header files which were under `/usr/include` no longer exists and been moved to Xcode: `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include` and CLI tools: `/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include`. output: ``` % which pkg-config /usr/local/bin/pkg-config % pkg-config --cflags --libs "libxml-2.0 > 2.6.17" -I/usr/include/libxml2 -lxml2 % pkg-config --variable pcfiledir "libxml-2.0 > 2.6.17" /usr/local/Homebrew/Library/Homebrew/os/mac/pkgconfig/10.14 % cat /usr/local/Homebrew/Library/Homebrew/os/mac/pkgconfig/10.14/libxml-2.0.pc prefix=/usr exec_prefix=${prefix} libdir=${exec_prefix}/lib includedir=${prefix}/include modules=1 Name: libXML Version: 2.9.4 Description: libXML library version2.

之前用安装包装一下就不用管了，现在没了。

这个很棒！我对编译打包这些不怎么懂，每次出问题总要折腾半天。

BTW，听说macport不用mac自带的library，会不会没有这些问题？
