最近在Ubuntu16.04的系统上跑SDK linux的IPC demo, 出现了如下问题：
make[1]: Leaving directory '/home/suafie/ti/SDK/board-support/linux-4.19.94+gitAUTOINC+be5389fd85-gbe5389fd85'
=================================
Configuring IPC
=================================
. /home/suafie/ti/SDK/linux-devkit/environment-setup; \
cd /home/suafie/ti/RTOS; \
./configure ${CONFIGURE_FLAGS} \
CC=${TOOLCHAIN_PREFIX}gcc \
--prefix=/usr \
PLATFORM=66AK2E \
KERNEL_INSTALL_DIR=/home/suafie/ti/SDK/board-support/linux-4.19.94+gitAUTOINC+be5389fd85-gbe5389fd85
/bin/sh: 行 2: ./configure: 没有那个文件或目录
Makefile:361: recipe for target 'ti-ipc-linux-config' failed
make: *** [ti-ipc-linux-config] Error 127
想请教一下为什么会出现：/bin/sh: 行 2: ./configure: 没有那个文件或目录，怎么解决呢。
