uClibc-0.9.27 with locale for ntfs-3g

[Jorgen Lundman]

It seems that part of the build procedure it hops into extra/locale/ and 
runs "make". But this appears to fail:

ishift 2  tshift 10  size 22608
smallest = 5776
setting ishift 5  tshift 1
make: *** [wctables.h] Segmentation fault (core dumped)

#0  0x08049018 in main (argc=Cannot access memory at address 0x0
) at gen_wctype.c:293
293                     memset(widtht, 0, sizeof(widtht));


However, removing -O2:

gcc -g -Wall  -D__UCLIBC_GEN_LOCALE gen_wctype.c -o gen_wctype

.. lets "make" complete, and reach what I assume is the end:

cat c8tables.h wctables.h locale_mmap.h >> uClibc_locale_data.h
cat uClibc_locale_data.h | awk 'BEGIN{i=1}{ if ( /WANT_/ ) i = /endif/ ; 
else if (i) print  }' > ../../include/bits/uClibc_locale_data.h



Not entirely sure how you can test locale, but I at least now get this 
result:

#include <stdio.h>
#include <locale.h>

int main(int argc, char *argv)
{
   char *p, buffer[] = { 
0xe6,0x97,0xa5,0xe6,0x9c,0xac,0xe8,0xaa,0x9e,0x0a };

   p = setlocale(LC_ALL, "");
   printf("setlocale(LC_ALL) returns '%s'\n", p ? p : "(null)");

   p = setlocale(LC_ALL, "ja_JP.UTF-8");
   printf("setlocale(LC_ALL) returns '%s'\n", p ? p : "(null)");

   printf("Test: %s\n", buffer);
}

# ./locale_test
setlocale(LC_ALL) returns 'C'
setlocale(LC_ALL) returns 'ja_JP.UTF-8'
Test: 日本語
