c++ - 使用分词器时出现 QUEX_PATH 问题

Question

我正在尝试安装 trainable-tokenizer。我已经按照自述文件安装了所有依赖项。这是可训练分词器 https://github.com/jirkamarsik/trainable-tokenizer .我已经使用来自 quex.org 的安装程序安装了 quex.deb，它是 trainable-tokenizer 的依赖项。

当我尝试执行 sudo make install 时出现以下错误

ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ sudo make install 
[  6%] Building FeaturesReader with quex
Environment variable QUEX_PATH has not been defined.
error: environment variable 'QUEX_PATH' is not defined.
error: your system is 'posix'.
error: if you are using bash-shell, append the following line
error: to your '~/.bashrc' file:
error:
error: export QUEX_PATH=directory-where-quex-has-been-installed
make[2]: *** [quex_files/trtok_read_features_FeaturesReader] Error 255
make[1]: *** [CMakeFiles/trtok.dir/all] Error 2
make: *** [all] Error 2

但我已经设置了 QUEX_PATH。

ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ echo $QUEX_PATH 
/opt/quex/quex-0.65.4/
ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ ll /opt/quex/quex-0.65.4/

我还添加了 export QUEX_PATH=/opt/quex/quex-0.65.4/ 到 .bashrc

ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ vim ~/.bashrc
ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ echo $QUEX_PATH 
/opt/quex/quex-0.65.4/
ThinkPad-T430:~/tmp/OpenFST/tokenizer/trainable-tokenizer/src$ sudo make install
[  6%] Building FeaturesReader with quex
Environment variable QUEX_PATH has not been defined.
error: environment variable 'QUEX_PATH' is not defined.
error: your system is 'posix'.

但我仍然得到同样的错误。

Answer 1

我使用 -I 标志解决了这个问题。我必须使用 quex -I。
