我想用仁金编译units软件包，目前在在线存储库中不起作用，请参见http://packages.renjin.org/package/org.renjin.cran/units/0.6-3/build/5
pom.xml，请参见https://github.com/nuest/renjin-docker/blob/master/geospatial-packages/units/pom.xml library('org.renjin.cran:Rcpp')，但是当我在mvn clean install上运行units时，出现以下错误：< / li>

有人知道如何告诉Renjin在哪里找到Rcpp.h吗？

答案 0 :(得分：1)
如果您使用Maven构建软件包，则还需要添加Rcpp标头作为依赖项：
public partial class Form1 : Form
{
private TableLayoutPanel _tableLayout;
private int _selectedRow = -1;
public Form1()
{
InitializeComponent();
var button = new Button()
{
Text = "Add Text"
};
button.MouseClick += AddText;
this.Controls.Add(button);
_tableLayout = new TableLayoutPanel()
{
Dock = DockStyle.Fill,
AutoScroll = true,
AutoSize = true,
AutoSizeMode = AutoSizeMode.GrowAndShrink,
CellBorderStyle = TableLayoutPanelCellBorderStyle.Single
};
_tableLayout.MouseClick += SelectRow;
this.Controls.Add(_tableLayout);
}
private void SelectRow(object sender, MouseEventArgs e)
{
_selectedRow = GetRowColIndex(_tableLayout, e.Location).Value.Y;
}
private void AddText(object sender, MouseEventArgs e)
{
_tableLayout.ColumnStyles.Add(new ColumnStyle() { SizeType = SizeType.AutoSize });
_tableLayout.RowStyles.Add(new RowStyle() { SizeType = SizeType.AutoSize });
_tableLayout.Controls.Add(new TextBox(), 0, _selectedRow);
}
Point? GetRowColIndex(TableLayoutPanel tlp, Point point)
{
if (point.X > tlp.Width || point.Y > tlp.Height)
return null;
int w = tlp.Width;
int h = tlp.Height;
int[] widths = tlp.GetColumnWidths();
int i;
for (i = widths.Length - 1; i >= 0 && point.X < w; i--)
w -= widths[i];
int col = i + 1;
int[] heights = tlp.GetRowHeights();
for (i = heights.Length - 1; i >= 0 && point.Y < h; i--)
h -= heights[i];
int row = i + 1;
return new Point(col, row);
}
}
您可以使用plyr的pom文件作为示例。
请注意，如果您只想构建与Renjin一起使用的软件包，则命令行工具要简单得多：
<dependency>
<groupId>org.renjin.cran</groupId>
<artifactId>Rcpp</artifactId>
<version>0.12.13-renjin-15</version>
<classifier>headers</classifier>
<scope>provided</scope>
</dependency>
这将负责下载所需的依赖项并生成一个jar文件。
请注意，Renjin不支持依赖于外部本机库的软件包。您可以从automated build logs中看到，由于依赖udunits2，units软件包将失败。
这就是在我们的打包站点中单位打包为labeled as incompatible的原因。
