@section Linking with -lm or -lc leads to crash
|
|
|
|
Currently, @code{/usr/lib/libm.a} and @code{/usr/lib/libc.a} are
|
|
symbolic links to libcygwin.a, where this stuff is actually implemented.
|
|
You need not explicitly link with -lm or -lc.
|
|
|
|
In fact, you @strong{must not} link with -lm or -lc, or your application
|
|
will crash. This is a bug, and it is being worked on.
|
|
|
|
Providing empty stub libraries for libm.a and libc.a is not considered
|
|
workable, because some packages look for symbols there.
|
|
|
|
There are some discussions of this in the mailing list. See

@section Ctrl-S hangs rxvt and xterm
|
|
|
|
This is a bug in the Cygwin pty code. It should be fixed in the next
|
|
release.
|
|
|
|
@section dllwrap is broken
|
|
|
|
Any invocation of dllwrap results in the error
|
|
|
|
@code{/usr/bin/ld: warning: cannot find entry symbol __cygwin_dll_entry@@12}
|
|
|
|
This should be fixed in the next release. For details and a workaround,
