分享一下MacOS下编译Emacs 28 native-comp分支

[twlz0ne]

看到了 native-comp branch option · Issue #187 · d12frosted/homebrew-emacs-plus · GitHub

不过目前好像还编译不过，而且 @AndreaCorallo 不用 Mac，他也没法提供直接的帮助。如果 Nix 搞定，所有平台的编译都不成问题了。

[seagle0128]

也是。有必要让作者看看这个帖子，哈哈哈

[tumashu]

guix 也可以，和nix有类似的包管理机制

[twlz0ne]

看了一下，guix 是基于的 nix 的，但是语法更对 Emacs 用户的胃口。

gcc通过brew edit gcc 编译成功了

编译emacs的时候卡在了这步，有遇到过的吗， 怎么解决

这也有个比较详细的 macOS 下编译的帖子：

company的后端应该是有company-keywords把？

我遇到了差不多的问题, 你解决了吗

编译emacs的时候报错如下:

编译用的脚本:

    export CC="clang"

    export CFLAGS="${CFLAGS}-I/usr/local/Cellar/gcc/9.2.0_3/include"

    export CPPFLAGS="${CFLAGS}"

    export LDFLAGS="${LDFLAGS}-L/usr/local/Cellar/gcc/9.2.0_3/lib"

    export LIBXML2_CFLAGS=`xml2-config --cflags`

    export LIBXML2_LIBS=`xml2-config --libs`

    ./autogen.sh

    ./configure \
      --prefix="${HOME}"/gccemacs \
      --with-nativecomp 

    make -j4

这是什么问题?

[wanglm]

LDFLAGS 改成 /usr/local/Cellar/gcc/9.2.0_3/lib/gcc/9 试试？

[CapsuleEXY]

谢谢你的回复, 我刚试了, 没有用. 我觉得和gcc已经无关了, 这应该是emacs本身的源码的问题;

[CapsuleEXY]

请问一下, 你用的emacs feature/native-comp 的commit id是多少

[wanglm]

commit ab8fed0a96a55107895e6105e7b0e4b6735156d7 (HEAD -> feature/native-comp, origin/feature/native-comp)

Author: Andrea Corallo [email protected] Date: Thu Mar 12 22:36:39 2020 +0000

* Do not produce .eln files when a byte compilation error happen

Have the byte compiler signal an error when compilation fails to stop
native compilation too.

[jixiuf]

目前还在尝试中 ，主要是编译太慢， 还没看出成果， 从现有的输出来看 似乎有 Segmentation fault，但是还没有结束 处于Waiting for unfinished jobs… 中 ，对make 不熟， 不知道这算不算异常 正在等待

这是我用的编译脚本。

jixiuf/vmacs/blob/master/bin/build-emacs.sh#L1

另外也分享下 brew 编译gcc9.3 的脚本与补丁

https://github.com/jixiuf/vmacs/blob/master/bin/gcc9.3.patch#L1

[Youmu]

后端都是默认的，没改动过

[jixiuf]

咨询一个问题，你编译成功的native-comp 版本 只是终端下的吗？ 图形界面下能用吗。

[CapsuleEXY]

我的编译脚本和你的基本没差别, 我现在用的emacs commit id是 “16ec5f5f2ffd9e114262b0a3a717b772ee0350ae”, 我直接用feature/native-comp 就会出现segmentation fault. 但是我用 16ec5f5f2ffd9e114262b0a3a717b772ee0350ae 这个源码编译出来的emacs打开之后没有 native-comp-async这个函数, 而且也没有生成eln文件, 虽然编译没报错, 但还是感觉没成功

[liushihao456]

图形界面也可以用

[liushihao456]

你们是Mojave还是Catalina，可能Catalina下很多软件会出问题，我是Mojave

[wanglm]

@CapsuleEXY 在我这里，使用脚本编译在 ELC+ELN 时会出现Segmentation fault. 但用 ./configure --with-nativecom LDFLAGS=... && make -j4 编译就很顺利。

[CapsuleEXY]

我是mojave.

我如果用CC="clang"编译, 就会出现这种error:

如果用CC=”gcc“编译, 就会出现: missing “gdk/gdkx.h” . 这应该可以解决, 但我还是倾向于用clang编译, gcc编译只能 --without-ns

你clang编译没有出问题吗? 另外请问一下emacs的源码你用的commit id
