[Mono-devel-list] embedded mono: undefined reference to _wapi_FD_SET and _wapi_select

[Mohammad DAMT]

Hi,
I have an embedded mono which uses UNIX sockets.

	...
  1           FD_ZERO (&z);
  2           FD_SET (socket, &z);

  3           tv.tv_sec = 10;
  4           tv.tv_usec = 0;

  5           if (select (socket + 1, &z, NULL, NULL, &tv)) {
	...

compilation went through but when linking with this:

gcc `PKG_CONFIG_PATH=/opt/mono/lib/pkgconfig pkg-config mono --libs` -o 
prog thread.o file.o

it failed with message:
thread.o(.text+0x588): In function `main_thread':
: undefined reference to `_wapi_FD_SET'
thread.o(.text+0x5e0): In function `main_thread':
: undefined reference to `_wapi_select'
collect2: ld returned 1 exit status

when I link with

gcc `PKG_CONFIG_PATH=/opt/mono/lib/pkgconfig pkg-config mono --libs` -o 
prog thread.o file.o /opt/mono/lib/libmono.a

it succeed but when I run prog, it segfaulted on line 2.

I use mono 0.26, fyi, it worked fine with 0.25 (compile, link, and 
run). 
what did I miss?
