7Hi,
8
9This patch adds 'make menuconfig' support to EGLIBC.
10
11
12EGLIBC can re-use the Linux kernel kconfig host tools ('conf' and 'mconf') unmodified, by passing appropriate environment variables and with some pre- and post-processing on the input/output config files.
13
14There are three new make targets supported, which all are defined in the new libc/options-config/Makefile, which is included by the top-level libc/Makefile:
15
16- 'make defconfig'. This passes 'libc/option-groups.defaults' to 'conf' as a default config, and outputs 'option-groups.config' to the top-level build directory, which will be the same as the default config.
17
18- 'make config'. This is the same line-oriented interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
19
20- 'make menuconfig'. This is the same menu-based interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
21
22
23Pre-Processing:
24
25
26The Linux kernel kconfig tools expect a prefix of "CONFIG_" on all config option names, but EGLIBC expects a prefix of "OPTION_". The pre-processing script, libc/options-config/config-preproc.pl, simply replaces "CONFIG_ with "OPTION_" in the given config file. The libc/options-config/Makefile passes the script output to a temporary config file, which is then passed to 'conf' or 'mconf'.
27
28Post-Processing (libc/options-config/config-postproc.pl):
29
30
31- Disabled options are output as a comment line of the form "# CONFIG_FOO is not set". This needs to be changed to an explicit "CONFIG_FOO=n" in order to be compatible with 'option-groups.awk' which generates the option-groups.h header.
32
33- "CONFIG_" prefix is changed back to "OPTION_".
34
35
36- The kconfig tools will not output anything for options that depend on a parent option, when the parent option is disabled. This implicit disable must be converted to an explicit "CONFIG_FOO=n" in order to be compatible with the way EGLIBC overrides the default option settings in 'libc/option-groups.defaults' with those in 'option-groups.config'.
37
38
39A new configure option, '--with-kconfig=<PATH>', tells EGLIBC where to find the pre-built 'conf' and 'mconf' host tools from Linux kernel builds.
40
41libc/EGLIBC.cross-building is updated to include instructions for using '--with-kconfig' for the final EGLIBC build, and shows how and when to run 'make *config'.
42
43libc/EGLIBC.option-groups is updated to include new information on the menuconfig support.
44
45Thanks,
46
47attached is the updated patch to address above issues.

70+
71+Note the additional '--with-kconfig' option. This tells EGLIBC where to
72+find the host config tools used by the kernel 'make config' and 'make
73+menuconfig'. These tools can be re-used by EGLIBC for its own 'make
74+*config' support, which will create 'option-groups.config' for you.
75+But first make sure those tools have been built by running some
76+dummy 'make *config' calls in the kernel directory:
77+
78+ $ cd $obj/linux
79+ $ PATH=$tools/bin:$PATH make config \
80+ > ARCH=$linux_arch CROSS_COMPILE=$target- \
81+ $ PATH=$tools/bin:$PATH make menuconfig \
82+ > ARCH=$linux_arch CROSS_COMPILE=$target- \
83+
84+Now we can configure and build the full EGLIBC:
85+
86+ $ cd $obj/eglibc
87+ $ PATH=$tools/bin:$PATH make defconfig
88+ $ PATH=$tools/bin:$PATH make menuconfig
89 $ PATH=$tools/bin:$PATH make

990-At the moment, EGLIBC performs no sanity checks on the contents of
991-'option-groups.config'; if an option group's name is mistyped, the
992-option group is silently included in the build. EGLIBC should check
993-that all variables set in 'option-groups.config' are proper option
994-group names, and that their values are appropriate.
995-
996-Some portions of EGLIBC depend on others; for example, the Sun Remote
997-Procedure Call functions in 'sunrpc' depend on the networking
998-functions in 'inet'. The sanity checking described above should check
999-that the selection configuration satisfies dependencies within EGLIBC,
1000-and produce a legible error message if it does not. At the moment,
1001-inconsistent configurations produce link errors late in the build
1002-process.
1003-
1004-The Linux kernel's configuration system provides interactive
1005-interfaces for creating and modifying configuration files (which also
1006-perform the sanity checking and dependency tracking described above).
1007-EGLIBC should provide similar interfaces.

10This patch builds on the menuconfig patch for EGLIBC.
11
12
13There are a few options that have non-boolean types, that would benefit from the new 'make *config' support:
14
15EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE (int)
16EGLIBC_NSSWITCH_FIXED_CONFIG (string)
17EGLIBC_NSSWITCH_FIXED_FUNCTIONS (string)
18
19
20The patch converts these to real options in libc/option-groups.def. Also, libc/scripts/option-groups.awk is modified to output a '#define' line for int, hex, or string options encountered in the config file.
21
22In the post-processing script config-postproc.pl, a small change is needed: for any boolean option FOO that is implicitly disabled in the kconfig output, make sure that option is indeed a boolean before printing the explicit OPTION_FOO=n.
23
24Finally, libc/malloc/Makefile passes __OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE as a CPPFLAGS, which is not necessary anymore because this macro will now be present in the generated header.
25
26attached is the updated patch to address above issues.

8As part of the menuconfig development, I encountered some outdated information in the cross-build instructions, libc/EGLIBC.cross-building. This patch updates the file with new (and tested) instructions. It is unrelated to the menuconfig support, but applies after.
9
10My testing was done with an ARM target, and an x86_64 Linux host, so I converted the instructions to use those host/target types from the original i686/powerpc. Hope that's ok.
