交叉編譯gcc失敗（Python）

Question

我正在嘗試編譯Python以將其移植到具有DD-WRT（DD-WRT v24-sp2（SVN版本：14896））的路由器（ASUS RT-N16）。 JFFS2（因此是ipkg）和Optware不是選項。 我需要做一個直接的交叉編譯。 我是交叉編譯的新手。

我嘗試按照以下指示進行操作： http : //www.cnx-software.com/2011/02/04/cross-compiling-python-for-mips-and-arm-platforms/

我也嘗試了這些指示，但是得到了相同的錯誤（這就是我剛剛完成的操作）： http : //www.embecosm.com/appnotes/ean9/ean9-howto-newlib-1.0.pdf

但是我一直得到以下信息：

任何建議將不勝感激。 我擁有要在其上進行編譯的系統，但除非上班了，否則我將無法訪問路由器（直到下周二才會回到那里）。 但是問題是交叉編譯器。 據我了解，一旦全部編譯完畢，只需要將文件夾復制（通過scp）到路由器。 謝謝！

我想知道您是否在桌面上安裝了mipel-gcc交叉編譯器。

由於路由器具有mipsel架構，因此具有Little Endian（MIPSEL）格式的MIPS架構。 您必須先安裝mipsel-gcc交叉編譯器，然后才能在該體系結構中編譯python代碼。 編譯代碼后，即可在路由器上運行代碼。

一旦安裝了mipsel，就可以將其添加到路徑變量中，並且代碼將起作用。
