IMX6 TSLIB库编译交叉工具检测问题

云心水影

ubuntu12.04,32位版本，编译工具：gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux，在编译时，依据说明书操作如下：
1、指定编译工具：
root@ubuntu:/home/imx6ull/imx6ulltools/tslib# export CC=/home/imx6ull/imx6ulltools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-gcc-4.9.23
2、 root@ubuntu:/home/imx6ull/imx6ulltools/tslib# ./autogen.sh
3、
root@ubuntu:/home/imx6ull/imx6ulltools/tslib# ./configure --host=arm-linux-gnueabihf --prefix=/usr/local/tslib ac_cv_func_malloc_0_nonnull=yes

依据上面信息：系检测不到交叉编译工具。请版主帮忙一下，谢谢！

软件01

export PATH=/home/myzr/6ul-tools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/binPATH
arm-linux-gnueabihf-gcc -v
检测到后，再试试,(其他环境变量也设置一下)

这样操作后还是不行：

好像能检测到交叉工具，但编译还是用的GUN C++

tslib移植
编译tslib库
1 解压tslib

unzip tslib-master
2 进入tslib目录，指定交叉编译工具

export CC=/home/myzr/6ul-tools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-gcc-4.9.23
此处应该是4.9.2，工具包里没有4.9.23.
