HI All<br>
I am using boost accumulators.<br>
<br>
These 2 lines use to work fine  with current version of boost in LInux.<br>
<br>
accumulator_set&lt; double, stats&lt; tag::covariance&lt;double, 
tag::covariate1&gt; &gt; &gt; acc_cov;<br>

accumulator_set&lt; double, stats&lt; tag::variance &gt; &gt; acc_var;
<br>
<br>
When I moved to a Sun machine where it is installed boost v1.40<br>
I have this building error<br>
<br>
&quot;/opt/boost/boost/accumulators/framework/depends_on.hpp&quot;, line 276: 
Error:&lt;no tag&gt; cannot be initialized in a constructor.<br>
&quot;/opt/boost/boost/fusion/container/list/cons.hpp&quot;, line 85:     Where: 
While instantiating 
&quot;boost::accumulators::detail::accumulator_wrapper&lt;int, 
int&gt;::accumulator_wrapper(const 
boost::accumulators::detail::accumulator_wrapper&lt;int, int&gt;&amp;)&quot;.<br>
&quot;/opt/boost/boost/fusion/container/list/cons.hpp&quot;, line 85:     Where: 
Instantiated from non-template code.<br>
1 Error(s)<br>
<br>
Do you know how can I fix those errors and why I have this issue?<br>
Thanks<br>
<br>
