Subject: [ruby-core:103392] [Ruby master Bug#17793] `shorten-64-to-32` error for 32-bit Android due to `struct stat` definition
Date: Mon, 12 Apr 2021 05:30:35 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-91486.20210412053034.48178@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-17793.20210411173911.48178@ruby-lang.org
Issue #17793 has been updated by nobu (Nobuyoshi Nakada).
Sorry, the second patch had a typo, `SIZEOF_DEVT` should be `SIZEOF_DEV_T`.
Is it fine?

Bug #17793: `shorten-64-to-32` error for 32-bit Android due to `struct stat` definition

[Here is a failure log for armv7a-android from CI.](http://rubyci.s3.amazonaws.com/crossruby/crossruby-master-armv7a-android30/log/20210411T143751Z.fail.html.gz)
This failure is because `struct stat` for 32-bit Android is defined as follows. Note that the member `st_dev` is of type `unsigned long long` (instead of `dev_t`), and `st_mode` is of type `unsigned int` (instead of `mode_t`).
```c
struct stat {
unsigned long long st_dev;
unsigned char __pad0[4];
unsigned long __st_ino;
unsigned int st_mode;
nlink_t st_nlink;
uid_t st_uid;
gid_t st_gid;
unsigned long long st_rdev;
unsigned char __pad3[4];
long long st_size;
unsigned long st_blksize;
unsigned long long st_blocks;
struct timespec st_atim;
struct timespec st_mtim;
struct timespec st_ctim;
unsigned long long st_ino;
};
```
I personally avoid these errors by passing the following two arguments to `./configure`. I am not 100% sure this results in no other problems.
```
rb_cv_dev_t_convertible=ULL
rb_cv_mode_t_convertible=UINT
```
