; m D7 q/ S s3 g9 B$ T最近在windows7上编译rtt，考虑到用cygwin上的git,svn同步代码方便，希望把scons编译方式也加到cygwin上，遇到了一个5 O: F, B& d5 M' r7 p. p! n# A' U& i
sh: ARM-none-eabi-gcc: command not found- o4 Z5 r8 q7 @8 k4 q/ s: D
的问题2 T0 R* p5 p# @5 _+ r& ?! g
具体步骤如下：
1 B- `. P+ _/ k, ~! O1 安装cygwin，选择full install(带有python)( ~. y; q, |3 t; `
2 安装scons (python setup.py install)5 o3 \. B. h; I0 S2 l9 }
3 安装arm--none-eabi-i686-mingw32.tar.bz2 (tar -jxvf arm--none-eabi-i686-mingw32.tar.bz2)7 O7 S: ]; l3 F6 W
4 将arm-none-eabi-i686-mingw32解压后的路径export到PATH里! ^- |. H" }8 D" n8 P7 i5 {& a1 x
在wh44b0下做scons提示如下& d. {; H) f, s

是可以把application.o生成到build下的3 Y1 z0 h4 J0 S5 T; r" }4 z
6 d4 G& h+ r" A) p: [
可能问题就出在scons里对arm-none-eabi-gcc查找上出了问题，在building.py里加了一个 print os.environ[‘PATH’]
