struct lconv from local.h don't contain decimal_point

[Xavier Bigand]

Hi,

I am trying to compile lua with my engine but the member decimal_point
isn't present in the lconv struct.

For the moment I force the result as '.' character. Is their a way to
get a fixed local.h?

Bionic doesn't really support c locale; you should use the Java APIs to get this kind of information.

There are various other fields missing from Android versions of C structs too (pw_gecos, etc).

If lua uses autoconf, it's quite easy to add AC_CHECK_MEMBERS checks for the missing struct members and #ifdef out the offending code.  See http://github.com/anguslees/openembedded-android/commit/82439ae0143a158bcf9953ab766d4a26c3a1a6ce for my patch to do this for glib, for example.

This is easy if you don't actually *need* the correct decimal point character.  If you are going to show this to a user, then you're out of luck - you probably need to go find the appropriate locale information in Java-land (and perhaps implement your own more correct lconv replacement functions if that makes the code changes easier).

Thx,

It's not really important for me to have the right value, I am not
using lua strings for applications texts.

We're not going to modify any structure that is part of the published stable headers, including the C ones.

This would break the ABI and make native code crash randomly otherwise (think stack corruption).
