Hello,
i'm trying to port Kaffe (www.kaffe.org) to a Windows Mobile Platform
using CeGCC, but i have a problem with seekdir and telldir functions.
For example, if i try to compile with CeGCC this program:
----- start telldir.c ----
#include <dirent.h>
#include <sys/types.h>
#include <errno.h>
#include <string.h>
#include <stdio.h>
int main(){
DIR *mydir = opendir(".");
if (mydir == NULL)
{
printf("Err: %s\n", strerror(errno)) ;
}
else
{
long int currLoc = telldir(mydir);
printf("telldir : %d\n", currLoc);
printf("Seekdir\n");
seekdir(mydir, currLoc);
}
}
---- end telldir.c -----
i get this error:
[EMAIL PROTECTED] /cygdrive/c/Code
$ arm-wince-cegcc-gcc-4.1.0 -std=gnu99 telldir.c -o telldir-arm.exe

but a compilation with gcc-x86 is successful:

Seekdir
I'm using Cygwin on Windows XP with CeGCC 0.51 binary package (the
file i downloaded from sourceforge.net is
cygwin-cegcc-cegcc-0.51.0-1.tar.gz). It is located in /opt/cegcc.
the command "arm-wince-cegcc-gcc-4.1.0 -v" gives:
Using built-in specs.
Target: arm-wince-cegcc
Configured with: /home/pedro/cegcc/0.51/src/gcc/configure --with-gcc
--with-gnu-ld --with-gnu-as --target=arm-wince-cegcc
--prefix=/opt/cegcc --enable-threads=win32 --disable-nls
--enable-languages=c,c++ --disable-win32-registry --disable-multilib
--disable-interwork --without-newlib --enable-checking --with-headers
Thread model: win32
gcc version 4.1.0
It seems that telldir and seekdir functions are not defined in libc.
In fact if i try to show the symbol on libc.a ( compiled for x86) i
give:
$ nm /lib/libc.a | grep seekdir
00000000 I __imp___seekdir
00000000 T __seekdir
00000000 I __imp___seekdir64
00000000 T __seekdir64
seekdir.o:
U __imp___seekdir64
00000000 I __imp__seekdir
00000000 T _seekdir
while for libc.a (bundled with CeGCC):
[EMAIL PROTECTED] /cygdrive/c/Code
$ arm-wince-cegcc-nm.exe /opt/cegcc/arm-wince-cegcc/lib/libc.a | grep seekdir
Can someone give me a suggestion on how to solve this problem ?
Thank you very much,
Mario Latronico
