error running linker

error running linker

[Richard Morgan]

Hi,

While running an ant build cc task (cpptasks: Compile tasks for Apache 
Ant - cc (sourceforge.net) 
<http://ant-contrib.sourceforge.net/cpptasks/antdocs/CCTask.html>), when 
it reached the Link step I received the following output:

Starting Link

                 1 [main] 5672 find_fast_cwd: WARNING: Couldn’t compute 
FAST_CWD pointer.  Please report this problem to the public mailing list 
cygwin@cygwin.com <mailto:cygwin@cygwin.com>

                 link: extra operand ‘/DLL’

I don’t know if the extra operand is the problem, I don’t supply it, it 
is likely generated by the “outtype=’shared’” parameter of the cc task, 
so I don’t have an easy means to experiment with changing that since I 
need a shared library to be generated.

If you need any other info let me know.

Regards,

Rick Morgan

If this command is getting its parameter from a previous command, make
sure to sanitize the stderr that comes from Cygwin.  Normally, this
isn't a problem, but ant specifically included stderr and stdout
together when parsing a command.

https://github.com/java-native-access/jna/commit/2714a017c9fada761e3d175d1e03f1d3bccaa14f

This above example is using ant's "apply", but any ant executed output
can suffer from this problem where stderr is mixed with stdout.  It's
not a cygwin bug, but rather a nuance with ant that surfaces with
Cygwin.
