ruby.git/test/mkmf/test_configuration.rb, branch v3_4_9 The Ruby Programming Language mkmf: Add the extra option `--with-verbose` to enable verbose mode. (#7863) 2023-05-29T08:09:32+00:00 Jun Aruga junaruga@users.noreply.github.com 2023-05-29T08:09:32+00:00 57459b83a9a52ab921094a1562fe3056df9a437a This commit is to add an extra option to enable verbose mode (V=1) in the generated `Makefile` at runtime of the Ruby to print compiler command lines by the commands below when building native extensions. It's possible to enable the verbose mode by setting the environment variable `MAKEFLAGS="V=1"`[1] implemented in GNU make. However, I wanted to make a consistent user-interface not depending on the specific make's implementation. ``` $ ruby /path/to/extconf.rb -- --with-verbose ``` You can also add the extra option via rake-compiler gem. ``` $ rake compiler -- --with-verbose ``` If the extra option is not given, the value of the `RbConfig::CONFIG["MKMF_VERBOSE"]` enabled by the configure option below is used. ``` $ ./configure --enable-mkmf-verbose ``` For the unit tests, updated the following files. * The `test/mkmf/test_configuration.rb` was created to test the cases with the `configuration` method and this implementation. * Updated the `TestMkmf#assert_separately` to set the extra arguments in `test/mkmf/base.rb`. Updated tests using the `assert_separately`. * Added tests for `MakeMakefile#with_config` in the `test/mkmf/test_config.rb`.

This commit is to add an extra option to enable verbose mode (V=1) in the
generated `Makefile` at runtime of the Ruby to print compiler command lines by
the commands below when building native extensions. It's possible to enable the
verbose mode by setting the environment variable `MAKEFLAGS="V=1"`[1]
implemented in GNU make. However, I wanted to make a consistent user-interface
not depending on the specific make's implementation.

```
$ ruby /path/to/extconf.rb -- --with-verbose
```

You can also add the extra option via rake-compiler gem.

```
$ rake compiler -- --with-verbose
```

If the extra option is not given, the value of the
`RbConfig::CONFIG["MKMF_VERBOSE"]` enabled by the configure option below is
used.

```
$ ./configure --enable-mkmf-verbose
```

For the unit tests, updated the following files.

* The `test/mkmf/test_configuration.rb` was created to test the cases with the
  `configuration` method and this implementation.
* Updated the `TestMkmf#assert_separately` to set the extra
  arguments in `test/mkmf/base.rb`. Updated tests using the `assert_separately`.
* Added tests for `MakeMakefile#with_config` in the `test/mkmf/test_config.rb`.
