默认情况下编译系统找不到静态编译的tslib

/home/mr/tslib-build/lib目录下确定有已编译好的libts.a，并且使用反编译软件可以看到该静态库已经正确导出相关函数了。从输出的信息可以看到-L/home/mr/tslib-build/lib和-lts都正确的配置好了。请问是这个编译系统不支持静态编译的libts库吗，还是哪里操作有误呢？

这个不清楚，我用静态库没有问题。也有人遇到同样的问题，改成动态库就好了。

好吧😌

我也遇到一样问题，想问一下您是怎么处理的。 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

@PeachT 我后面使用的动态链接，编译了TSLIB的动态库后就可以正常链接了。你可以先检查一下/home/ylin/AWTK/tslib/build_dir/tslib/lib 目录下有没有正确的二进制库，还要检查他们的ABI是否兼容。
