Bug #15665: Cannot compile socket extension on Mojave
https://bugs.ruby-lang.org/issues/15665

* Author: franklinyu (Franklin Yu)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: 2.6.0
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
The `mkmf.log` is reporting that it cannot find `netinet6/in6.h`. I guess that previously it’s finding it in `/usr/include`, but as we all know Apple removed that path since Mojave. On my machine the current path is:

```
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/
```

The C compiler seems fine if I’m using it stand-alone. I tried compiling following snippet:

```c
#include <netinet/in.h>
int main() {}
int t(struct in6_addr *addr) {
    return IN6_IS_ADDR_UNSPECIFIED(addr);
}
```

And it works, although I have no idea which header it included. I tried both compiling it with `cc test.c`, and with the actual command in `mkmf.log`:

```
clang -I../../.ext/include/x86_64-darwin18 -I../.././include -I../.././ext/socket -I../.. -I../../. -I/opt/local/include -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -D_DARWIN_UNLIMITED_SELECT -D_REENTRANT -Wall -Wextra -Wpedantic -Wshadow -pipe -D__APPLE_USE_RFC_3542 -Werror
```

Both works without any warning/error.

## note

This only happens to 2.6.0 and 2.6.1. Releases in 2.5.x or below are not affected.

I couldn't reproduce this with Mojave.

It seems your development environment issue.

Status changed from Rejected to Open

@hsbt That location has been [deprecated](https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes#3035624):

> The command line tools will search the SDK for system headers by default. However, some software may fail to build correctly against the SDK and require macOS headers to be installed in the base system under /usr/include. If you are the maintainer of such software, we encourage you to update your project to work with the SDK or file a bug report for issues that are preventing you from doing so. As a workaround, an extra package is provided which will install the headers to the base system. **In a future release, this package will no longer be provided.**

Please be future-proof.

Do not change status field.

Maybe you can resolve this with `sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /`

That check is necessary only for very old, 6 years ago, header.
It is strange that `IN6_IS_ADDR_UNSPECIFIED` code cannot compile.
Could you show how it failed in mkmf.log?

That is a *workaround*. It will break in the future. Please read the bold text in the quote. If by your definition my environment is broken, then maybe next year *all* macOS user will have broken environment.

I’m busy now but I will provide the log in 48 hours. Thanks for this information.

I have verified that the changeset works for 2.6 on my machine. It is currently in trunk, which would go to 2.7 eventually; would it be backported to 2.6 branch?

I'm not sure nobu's changesets are bug or feature.

But this issue was marked with "Feature" by nobu. We never backport the new feature to stable versions.

}
```

And it works, although I have no idea which header it included. I tried both compiling it with `cc test.c`, and with the actual command in `mkmf.log`:

```
clang -I../../.ext/include/x86_64-darwin18 -I../.././include -I../.././ext/socket -I../.. -I../../. -I/opt/local/include -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -D_DARWIN_UNLIMITED_SELECT -D_REENTRANT -Wall -Wextra -Wpedantic -Wshadow -pipe -D__APPLE_USE_RFC_3542 -Werror
```

Both works without any warning/error.

## note

This only happens to 2.6.0 and 2.6.1. Releases in 2.5.x or below are not affected.

[ruby-core:93222] [Ruby trunk Feature#15665] Cannot compile socket extension on Mojave

[franklinyu]

Issue #15665 has been updated by franklinyu (Franklin Yu).


@nobu Please update, or is there any reason that this should be a feature instead of a bug?

----------------------------------------
Feature #15665: Cannot compile socket extension on Mojave
https://bugs.ruby-lang.org/issues/15665#change-78674

* Author: franklinyu (Franklin Yu)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
The `mkmf.log` is reporting that it cannot find `netinet6/in6.h`. I guess that previously it’s finding it in `/usr/include`, but as we all know Apple removed that path since Mojave. On my machine the current path is:

```
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/
```

The C compiler seems fine if I’m using it stand-alone. I tried compiling following snippet:

```c
#include <netinet/in.h>
int main() {}
int t(struct in6_addr *addr) {
    return IN6_IS_ADDR_UNSPECIFIED(addr);
}
```

And it works, although I have no idea which header it included. I tried both compiling it with `cc test.c`, and with the actual command in `mkmf.log`:

```
clang -I../../.ext/include/x86_64-darwin18 -I../.././include -I../.././ext/socket -I../.. -I../../. -I/opt/local/include -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -D_DARWIN_UNLIMITED_SELECT -D_REENTRANT -Wall -Wextra -Wpedantic -Wshadow -pipe -D__APPLE_USE_RFC_3542 -Werror
```

Both works without any warning/error.

Issue #15665 has been updated by nobu (Nobuyoshi Nakada).


I did set the tracker to "feature", since this added the support for "-Wpedantic" option, but will leave this to the branch maintainers.

[ruby-core:95792] [Ruby master Feature#15665] Cannot compile socket extension on Mojave

[naruse]

Issue #15665 has been updated by naruse (Yui NARUSE).


Usually -pedantic is applied automatically ruby core but not passed to extension libraries.
Such "suppress warnings" are usually not considered as a bug because it may cause side effect.

I knew that Ruby was compiled with `-pedantic`; wasn’t aware that this was for core only. Thanks a lot for the explanation. Look forward to the release in Christmas.
