ARM交叉编译protobuf时出错

编译脚本：

  1 #!/bin/sh
  2 
  3 export PREFIX=$HOME/soft/protobuf_arm/
  4 CLANG_TOOLCHAIN=$HOME/soft/arm-29-toolchain-clang
  5 export PATH=$CLANG_TOOLCHAIN/bin:$PATH
  6 export SYSROOT=$CLANG_TOOLCHAIN/sysroot
  7 export CC="armv7a-linux-androideabi29-clang --sysroot $SYSROOT"
  8 export CXX="armv7a-linux-androideabi29-clang++ --sysroot $SYSROOT"
  9 
 10 cd $HOME/github/c++/protobuf
 11 make clean
 12 ./autogen.sh
 13 ./configure --prefix=$PREFIX \
 14 --host=armv7a-linux-androideabi29 \
 15 --with-sysroot="${SYSROOT}" \
 16 --enable-shared \
 17 --enable-cross-compile \
 18 --with-protoc=$HOME/soft/protobuf_linux/protoc \
 19 CFLAGS="-march=armv7-a -D__ANDROID_API__=29" \
 20 CXXFLAGS="-frtti -fexceptions -march=armv7-a -D__ANDROID_API__=29" \
 21 LIBS="-llog -lz -lc++_static"
 22 make -j 12
 23 make install

配置没有错误，make错误：

我想尝试页面缓存.但是我找不到这个net.sf.ehcache.constructs.web.filter.SimplePageCachingFilter课,所以我得到了一个错误class not found

我该怎么办？

<filter>
  <filter-name>SimplePageCachingFilter</filter-name>
  <filter-class>net.sf.ehcache.constructs.web.filter.SimplePageCachingFilter
  </filter-class>
</filter>
