Step 8: Build Qt
(NOTE:触摸屏tslib的调试暂时不考虑。)
到目前为止的目标文件系统,具备了那些内容呢:
有etc目录和其中的启动文件,有存放在bin、sbin目录下的busybox可执行程序,lib库,其他目录如home、media、mnt、proc等,以及存放在opt目录下的Graphics SDK,包括它的库文件、驱动文件和demo文件。只有demo文件无错误的运行在目标板上了,才可以往下进行,否则,要继续修改Kernel代码或者Graphics SDK编译方式。
准备好文件系统,以及解压Qt源代码:
[maria@localhost qt-am335x]$ mkdir roofts.withSDK
[maria@localhost qt-am335x]$ cp ../ro otfs/* rootfs.withSDK/ -rv
[maria@localhost qt-am335x]$ tar xvf ../qt-everywhere-opensource-src-5.4.1.tar.gz -C .
从下面这个地址下载qmake.conf文件,并将它复制进Qt源代码目录,并根据主机的实际情况修改内容:

[maria@localhost qt-am335x]$ tar xvf Linux-TIarmv7-sgx-g++.tar.gz
[maria@localhost qt-am335x]$ ln -s qt-everywhere-opensource-src-5.4.1 qt-everywhere
