ubuntu g++: error: unrecognized command line option ‘-fno-plt’

今天在编译chineseocr_lite下面的psenet的时候出现了下面的错误：

g++: error: unrecognized command line option ‘-fno-plt’
Makefile:10: recipe for target 'pse.so' failed
make: *** [pse.so] Error 1
make: Leaving directory '/media/data/projects/OCR/chineseocr_lite/psenet/pse'
Traceback (most recent call last):

    raise RuntimeError('Cannot compile pse: {}'.format(BASE_DIR))
RuntimeError: Cannot compile pse: /media/data/projects/OCR/chineseocr_lite/psenet/pse

解决方法

sudo apt install gcc-6
sudo apt install g++-6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-6
