swoole扩展怎么编译进去

[dixyes]

像一般的扩展in-tree构建一样，你可以这么来构建带某个扩展的micro.sfx：

Like common extension in-tree build, you can build micro.sfx with some extension:

# 在php源码目录 / at php source dir
# clone swoole to ext/swoole / clone swoole到ext/swoole
git clone --depth 1 --branch <你喜欢的ref> https://github.com/swoole/swoole-src ext/myext
# 重新生成configure / regenerate configure
./buildconf --force
# congfigure
./configure <args like "--disable-cli --enable-micro"> --enable-<扩展名比如swoole>
# make
make -j`nproc`

注意的是，可能一些非官方扩展对in-tree构建的支持不是很好，你可能需要稍微修改一下它的源代码

Note here, some non-offical extensions may not compatible with in-tree build, you may need to patch its source.

特别的，对于swoole，多个swoole版本在in-tree构建时会以各种方式出错

As for swoole, variant swoole versions may error in in-tree build.

同时 swoole需要c++，这意味着你需要编译glibc或者libcpp，这将大大增加micro的大小

好的，谢谢，
我得去补充一下这方面的知识，如果其他扩展都能加入进去的话，相对来说，还是方便不少。

我试着编译了 swoole 4.6.2

I tried built with swoole 4.6.2

确实，swoole需要一些patch才能in-tree编译，我使用了这些patch：

Indeed, swoole need some patches to in-tree build, the patches I used:

nonghttp.patch

我单独编译并连接了nghttp，因此需要将swoole的nghttp代码删除：

I build and linked in nghttp, so I need remove nghttp codes in swoole:

clang.patch

swoole直接修改了clang编译时的CFLAGS，导致php代码无法正常编译， 我也使用了clang

swoole modified CFLAGS instantly when using clang, this cause php codes cannot compile normally

config_h.patch

in-tree编译时不使用config.h而是main/php_config.h，这导致HAVE_CONFIG_H预定义宏无法正常生效

when in-tree building, generated header is main/php_config.h not config.h, this causes HAVE_CONFIG_H macro not work

除此之外，swoole的php_swoole.h没有出现在扩展根目录，这导致configure无法正常找到定义，你还需要在扩展根目录放置任意名称（比如"php_swoole_for_configure.h"）的头文件，内容如下

Otherwise, swoole's php_swoole.h is not located in extension root dir, this cause configure cannot locate module definations, you need put a header at extension root dir with any name (like "php_swoole_for_configure.h") with content:

extern zend_module_entry swoole_module_entry;
#define phpext_swoole_ptr &swoole_module_entry

看来是做了硬编码的SAPI检查，加了个patch

谢谢。目前可以了，能搞一个Windows版本的吗？

[dixyes]

谢谢。目前可以了，能搞一个Windows版本的吗？

Swoole不支持windows，如果需要windows版，考虑Swow替代

[xieyuhua]

整一个撒，

哥，redis扩展也没有弄好呀

[dixyes]

试试这个

最近么的电脑，稍晚点再考虑phpredis里lzf zstd lz4之类的依赖

[xieyuhua]

搞不来c++，不然我自己搞了

[xieyuhua]

redis好了，

[dixyes]

（讲道理我的这俩项目里一行C++都没有

curl整上了，做解析静态库依赖花了点时间。 至于swoole的弃用，你需要适配下swoole的api。

怎么设置php.ini里面内容？？

我按照你的步骤执行

在php源码目录下

patch -p1 api/micro/patches/disable_huge_page.patch
patch -p1 api/micro/patches/zend_stream.patch
为啥不动呢，，

到是可以执行后面得步骤，，但是我编译出来的micro.sfx，结果感觉是我当前php环境,并不是我下载得源码php8.0版本得环境，我有点蒙了
