Mac OS X Leopart (v10.5) で glib をビルドする
前回 Linux でやったように Mac で glib のデバッグ版をビルドしようと configure したらこけたので、いろいろ調べたところ以下のようにしたらできた。
$ ./configure CFLAGS="-I/opt/local/include -L/opt/local/lib -g"
ところで、Mac ではコンパイル時と実行時に指定する共有ライブラリのパスが同じじゃないとダメみたいだ。Linux だと違っても問題なかったのに、なんでかねぇ。
gcc -o sample sample.c `pkg-config --cflags glib-2.0` -L/Users/.../glib-2.16.5/glib/.libs -lglib-2.0
実行するときは環境変数 DYLD_LIBRARY_PATH にデバッグ版のパスを指定する。Linux と Mac ではライブラリの探索パスの環境変数が違うので注意。実はさっき知ったんだけど。
