製作64位共享庫，動態鏈接到Mac OS X上的32位庫雪豹

更新：經過一些閱讀後，我發現這個問題是完全一般的，你不能在同一個進程中混合架構，所以64位Java不能像dlopen()這樣的32位庫像FMOD。是否有任何可能的解決方法，請記住我正在爲FMOD庫編寫我自己的C接口？製作64位共享庫，動態鏈接到Mac OS X上的32位庫雪豹

我需要在Max OS X上創建64位dylib，因爲Java本機訪問只喜歡64位機器上的64位庫。問題是，我的C源代碼動態地包含了FMOD，它在Mac上只提供32位dylib。當我嘗試沒有-m32選項編譯（因爲我必須輸出64位dylib）我得到以下錯誤：

gcc -dynamiclib -std=c99 -pedantic -Wall -O3 -fPIC -pthread -o ../bin/libpenntotalrecall_fmod.dylib ../../src/libpenntotalrecall_fmod.c -lfmodex -L../../lib/osx/

是不是應該可以從我的源代碼得到一個64位的dylib動態地包含32位庫？
