tslib1.4在UBUNTU下的编译

tslib1.4编译过程

./autogen.sh
echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache
# 设置目标机型，缓冲，安装路径
./configure --host=arm-linux --cache-file=arm-linux.cache --prefix=/opt/tslib
make
# 如果目标路径没有权限，需要加 sudo
make install

可能遇到的错误

gcc 新版本编译器对语法检查严格，在源文件 ./tests/ts_calibrate.c 中

// 源文件
// if ((calfile = getenv("TSLIB_CALIBFILE")) != NULL) {
//     cal_fd = open (calfile, O_CREAT | O_RDWR);
// } else {
//   cal_fd = open ("/etc/pointercal", O_CREAT | O_RDWR);
// }
// 需要更改成如下形式
if ((calfile = getenv("TSLIB_CALIBFILE")) != NULL) {
    cal_fd = open (calfile, O_CREAT | O_RDWR, 0777);
} else {
    cal_fd = open ("/etc/pointercal", O_CREAT | O_RDWR, 0777);
}

保存后重新编译即可
