tslib 找不到编译链接库的方法错误(动态 .so)(静态的 .a)都是不行

[GitYonglin]

文件都是可以找到的，因为只要lib目录下或者include目录下文件删除都不是下面的错误 https://www.mr-cn.net/2020/07/07/AWTK-GUI-in-Anyka-Arm-Linux/ 我编译了 1.4（https://github.com/libts/tslib/releases/download/1.4/tslib-1.4.tar.gz） 1.22（https://github.com/libts/tslib/releases/download/1.22/tslib-1.22.tar.gz） ./configure --disable-static --enable-shared --enable-input=shared --enable-linear=shared --enable-iir=shared --host=aarch64-linux-gnu --prefix=/home/ylin/AWTK/tslib/build_dir/tslib CC=/usr/bin/aarch64-linux-gnu-gcc CXX=/usr/bin/aarch64-linux-gnu-g++ 两个版本都是以下的错误 交叉编译我用的是树莓派3B， 不编译tslib 是可以运行的 直接在树莓派编译也一样的问题

https://github.com/PeachT/tslib_API_TEST 做了一个简单测试，是可以调用到 链接库中的API的 如果有大神知道怎么回事，指点一下，给点思路非常感谢！

做 ./configure前 先export ex: export PATH=$PATH:/opt/ivot/aarch64-ca53-linux-gnueabihf-8.4.01/bin export LD_LIBRARY_PATH=/opt/ivot/aarch64-ca53-linux-gnueabihf-8.4.01/lib 再做 ./configure and make

另外 c and cpp link 時需加入 extern "C" { void C_function(); }
