Re: [Discuss-gnuradio] libstdc++ error on Cygwin

[Howard Wong]

Hi,

 

I get the same problem on cygwin too.

But seems both g++ 4.3 and 3.4.4 were installed and 4.3 is the dominant. How to switch to 3.4.4? Thanks!

What might be going wrong here?

Someone wants gcc 4.3.2 libraries, but the Cygwin install instructions assume you are using gcc 3.4.4.  Is it possible that you have installed cppunit 1.12.1 instead of 1.12.0?  You need to be careful: Any updating of Cygwin packages will update cppupnit to 1.12.1 unless you specifically tell it not to in the "Pending" view of Cygwin setup.

As an aside, it is helpful when reporting problems like this to show a little more of the output, including the libtool and g++ commands that preceded the error message.
