我正在嘗試使用OpenEmbedded構建DTN。不幸的是，DTN 使用Tcl 8.3或8.4和DB 4.2,4.3,4.4或4.5，但bitbake使用的是Tcl 8.5和DB 5.0的 。OpenEmbedded中的DTN爲BeagleBoard
在OpenEmbedded的食譜目錄以外的其他文件中存在：

在某些時候，當bitbake的被配置DTN，會發生以下情況：
| checking for library containing pow... -lm
| checking for library containing dlopen... -ldl
| | configure: checking for tcl installation (version 8.4)
| checking for tcl.h (version 8.4) in /opt/OpenEmbedded/build/tmp/sysroots/armv7a-angstrom-linux-gnueabi usr/include... no

爲了解決這個我去了dtn_2.5.0.bb並添加了--with-tclver = 8.5。
DB發生同樣的事情，並再次解決它我做了同樣的事情。
一段時間之後，bitbake的時候被編譯如下發生：

那麼，有沒有什麼辦法「告訴」或bitbake的OpenEmbedded的使用由我選擇一個版本？
