gcc -shared するときに -c をつけてはいけない

Last updated at Posted at 2015-01-10
gcc -shared -fPIC -o libfunc.so -c func.c  -lpng

オブジェクトファイルになるが共有ライブラリにならない。実行バイナリのソースとのリンクは通るが依存ライブラリのリンクが通らなかったりわけがわからないことが起きる。

正しくは以下

gcc -shared -fPIC -o libfunc.so func.c  -lpng

共有ライブラリとして動かないのは他のオプションが原因なのかと思って3時間ぐらいハマった。
