到目前爲止,我已經在我的ubuntu系統上安裝了所有的交叉編譯軟件包,但遇到問題並且需要一些幫助。從linux到ARM-ELF(armv5tejl)的交叉編譯
Linux 2.6.28.7 #1 CST 2012 armv5tejl unknown

這是我需要交叉編譯的目標機器。編譯時應該使用哪些標誌?
arm-linux-gnueabi-gcc simple.c -march=armv5 -static -o simplev5
arm-linux-gnueabi-gcc simple.c -mcpu=arm926ej-s -static -o simple926
當我運行simplev5或simple926,顯示:
Segmentation fault
遵循@Steven P的意見,我檢查了文件格式,內容如下:
[email protected]:~/code$ file simplev5
simplev5: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=f0607da1d809a7d98636d76ee0e538fc828e3b65, not stripped
[email protected]:~/code$ file simple926
simple926: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=ed1e6fdade02c0d2c985a503dafb6efadd13522f, not stripped

可能的重複從Linux到ARM-ELF的交叉編譯(ARM926EJ-S/MT7108)](http://stackoverflow.com/questions/17336236/cross-compile-from-linux-to-arm-elf-arm926ej-s-mt7108)...這個'Linux 2.6.28.7 '是相當古老的,最新的Ubuntu cross-arm可能配置爲更新的Linux。即使「靜止」成功,您仍然有可能無法映射的「swi」調用。 –
[從零開始構建交叉編譯器](http://frank.harvard.edu/~coldwell/toolchain/)可能會有幫助。 [Crosstool-ng](http://crosstool-ng.github.io/)可能會很有用,但它至少會支持舊的GCC版本和可能的Linux版本。通常情況下,需要使用小補丁來使編譯器生成過時的依賴關係。 –
