IT練習ノート

IT関連で調べたこと(実際は嵌ったこと)を書いています。

(solved) The pkg-config package 'libpcre' is required but it could not be found.

Haskell

pkg-confgとして認識されているか確認する。

$ pkg-config --libs libpcre
Package libpcre was not found in the pkg-config search path.
Perhaps you should add the directory containing `libpcre.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libpcre' found

profileの編集

$ vim ~/.bash_profile 

.bash_profileに下記を追加。

export PKG_CONFIG_PATH=/usr/lib/pkgconfig

パスを登録

source ~/.bash_profile 

認識されていることを確認

$ pkg-config --libs libpcre
-lpcre
