Body
As mentioned in the comments, the original error described in the title is not thrust related, but due to use of <code>struct data</code>, when <code>data</code> is already typedef'ed. In response to the additional question posed in the comments, I merely was trying to state that I had not fully thought about the ramifications of using <code>thrust::device_vector<></code> inside a struct. When I said maybe consider using <code>thrust::device_ptr<></code> instead, I had in mind something like this, which seems to work for me: <pre><code>#include <stdio.h> #include <thrust/host_vector.h> #include <thrust/device_vector.h> #include <thrust/device_ptr.h> #include <thrust/sequence.h> #include <thrust/transform.h> #include <thrust/functional.h> #define N 10 typedef struct { thrust::device_ptr<float> dp1; thrust::device_ptr<float> dp2; int i; } data; int main(){ thrust::negate<int> op; data *mydata = (data *)malloc(sizeof(data)); thrust::host_vector<float> h1(N); thrust::sequence(h1.begin(), h1.end()); thrust::device_vector<float> d1=h1; mydata->dp1=d1.data(); mydata->dp1[0]=mydata->dp1[N-1]; thrust::transform(mydata->dp1, mydata->dp1 + N, mydata->dp1, op); // in-place transformation thrust::copy(d1.begin(), d1.end(), h1.begin()); for (int i=0; i<N; i++) printf("h1[%d] = %f\n", i, h1[i]); return 0; } </code></pre> Having said that, the original method of using <code>device_vector</code> inside a struct may work, I just don't know and have not explored it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
