r - 编译包时在仁进找不到rccp.h

Question

我想units在仁进编译这个包，目前在网上仓库里是不行的，见http://packages.renjin.org/package/org.renjin.cran/units/0.6-3/build/5

• 我pom.xml为当前版本的 udunits 创建了一个，请参阅https://github.com/nuest/renjin-docker/blob/master/geospatial-packages/units/pom.xml
• 我构建了一个 Dockerfile 用于编译包并拥有所需的编译器，请参阅https://github.com/nuest/renjin-docker/blob/master/0.9.2726/Dockerfile.builder
• 在从该 Dockerfile 构建的映像创建的容器中，我可以library('org.renjin.cran:Rcpp')在 R 会话中运行，但是在运行时mvn clean install出现units以下错误：

有人知道如何告诉仁进在哪里可以找到Rcpp.h吗？

有关我查阅的资源的更多详细信息，请参见此 GitHub 问题：https ://github.com/nuest/renjin-docker/issues/4

Answer 1

如果您使用 Maven 构建包，您还需要添加 Rcpp 标头作为依赖项：

<dependency>
  <groupId>org.renjin.cran</groupId>
  <artifactId>Rcpp</artifactId>
  <version>0.12.13-renjin-15</version>
  <classifier>headers</classifier>
  <scope>provided</scope>
</dependency>

您可以使用plyr的 pom 文件作为示例。

请注意，如果您只想构建一个与 Renjin 一起使用的包，那么命令行工具要简单得多：

renjin build units

这将负责下载所需的依赖项并生成 jar 文件。

请注意，Renjin 不支持依赖于外部本地库的包。您可以从自动构建日志中看到，由于对 udunits2 的依赖，units 包将失败。

这就是我们的包装网站中将单位包装标记为不兼容的原因。
