有人能帮我解决这个问题吗？我在 10.04 中可以正常工作，谢谢 Drew

答案1

在 12.04 中，你可以从软件包（sudo apt-get install gocr或从软件中心）安装 GOCR。准备好的源也可以使用：

apt-get source gocr
cd gocr-0.49
dpkg-buildpackage -rfakeroot
cd ..
sudo dpkg -i gocr_0.49-1_*.deb

（如果您没有，dpkg-buildpackage您可以安装它sudo apt-get install build-essential：）

如果您需要从非 Ubuntu 源进行构建，通常在主目录中安装软件并正确设置路径会更容易、更安全，例如：

cd gocr-0.49
./configure --prefix=${HOME}
make all install
export PATH=${PATH}:${HOME}/bin
gocr

其他软件可能需要设置LD_LIBRARY_PATH、PYTHONPATH等等。

答案2

cannot create regular file `/usr/local/bin/gocr': Permission denied

意味着它没有创建（或写入）文件的权限。 /usr/local/bin/由 root 所有，任何没有权限的标准用户（或桌面用户）都无法在那里创建文件。

尝试一下sudo。

./configure然后先跑sudo make install。
