( `" |# \2 d! z# e$ v- I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

的问题
具体步骤如下：

# q/ J5 A) G- Q* ^5 B2 安装scons (python setup.py install)
; ]7 N2 g) Q& C  ~5 i  {+ V' A1 h! l3 安装arm--none-eabi-i686-mingw32.tar.bz2 (tar -jxvf arm--none-eabi-i686-mingw32.tar.bz2)
/ x' i3 g$ X1 E" p- G# N& x' S4 将arm-none-eabi-i686-mingw32解压后的路径export到PATH里
在wh44b0下做scons提示如下
$ scons scons: Reading SConscript files ... /opt/CrossCompile/CodeSourcery/Sourcery_CodeBench_for_ARM_EABI/bin:/cygdrive/c/linux/rt-thread/tool/arm-2012.09/bin/:/home/dillon.min/bin:/cygdrive/c/software/jd-gui-0.3.5.windows:/usr/local/bin:/usr/bin:/cygdrive/c/Program Files (x86)/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_EABI/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Old-Pc-bak/d/share/android-sdk_r10-windows/tools:/cygdrive/c/Old-Pc-bak/d/software/java反编译:/cygdrive/c/Program Files/7-Zip:/cygdrive/c/Python25:/cygdrive/c/Python25/Scripts:/cygdrive/c/Program Files (x86)/Beyond Compare 3:/usr/lib/lapack scons: done reading SConscript files. scons: Building targets ... scons: building associated VariantDir targets: build arm-none-eabi-gcc -o build/application.o -c -mcpu=arm720t -D__FLASH_BUILD__ -O2 -Ibuild -I. -I/cygdrive/c/linux/rt-thread/rt-2457-git -I/cygdrive/c/linux/rt-thread/rt-2457-git/build -I/cygdrive/c/linux/rt-thread/rt-2457-git/include -I/cygdrive/c/linux/rt-thread/rt-2457-git/libcpu/arm/s3c44b0 -I/cygdrive/c/linux/rt-thread/rt-2457-git/libcpu/arm/common application.c sh: arm-none-eabi-gcc: command not found scons: *** [build/application.o] Error 127 scons: building terminated because of errors.
但是我手动执行

* v: [: b; q' z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’]
说明gcc的工具是在路径里的，就比较迷惑了

ESCAPE

scons用的路径是和系统中的PATH变量指向的路径是不一样的，需要在rtconfig.py中指定

我觉得不是arm-none-eabi-gcc的问题，我试过在cygwin下单独编译一个c文件，只要设置了CYGPATH环境变量，就可以正常编译，但是到了scons里面，就不行了，后来debug了一番，也没找到原因为什么scons调用的arm-none-eabi-gcc找不到头文件，就放弃了。

我觉得用Makfile方式编译linux应该是没有问题的话，一直没有实验过，回头有空试试看。
