tslib1.4编译过程‘__open_missing_mode’ 错误

tslib1.4编译过程

./autogen.shecho "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/tslibmake# 如果目标路径没有权限，需要加 sudomake 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
