Re: lib problems

For now I have got around this with the following code:

#ifdef WIN32

#ifdef unlink
#undef unlink
#endif

static int
init_unlink(const char *path)
{
while (unlink(path))
{
if (errno != EACCES)
return -1;
Sleep(100); /* ms */
}
return 0;
}

#define unlink(x) init_unlink((x))

#endif

cheers

OK, I have a C version of initdb that apparently works fine on Unix, and is only missing signal handling. (If anyone is curious and/or adventurous I can email you a copy).

When I compile on W32/Mingw I get this:

$ make
gcc -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -DPGBINDIR=\"/usr/local/pgsql/bin\" -DPGDATADIR=\"/usr/local/pgsql/share\" -L../../../src/port initdb.o -lpgport -o initdb

../../../src/port/libpgport.a(dirmod.o)(.text+0x22a):dirmod.c: undefined reference to `elog_finish'
make: *** [initdb] Error 1

The strange thing is I didn't get that this morning, but I assume it's clearly because I added some unlink calls.

Anyone have clues about how to fix this? Compile a copy of dirmod.c with FRONTEND defined, maybe? Or just remove the logging statements from pgunlink altogether - unlink should really be silent.

BTW, if the W32 timing problems that apply to unlink() also apply to rmdir(), we'll need a replacement for that too.

thanks
