如何在MAC OSX上與共享庫交叉編譯zlib？

Question

我正在嘗試爲MAC OSX上的powerpc嵌入式目標交叉編譯zlib庫。

我嘗試了建議： - http://liwende.blogspot.com/2008/02/how-to-cross-compile-zlib-openssl.html - http://www.ailis.de/~k/archives/19-arm-cross-compiling-howto.html - http://www.cnx-software.com/2011/10/06/cross-comping-zlib-for-arm-target/

但是，當庫名稱是不是沒有是.so這是名爲.dylib。

zlib-1.2.8]$ CC=powerpc-linux-gcc \ 
> AR=powerpc-linux-ar RANLIB=powerpc-linux-ranlib \ 
> AS=powerpc-linux-as LD=powerpc-linux-ld \ 
> LDSHARED="powerpc-linux-gcc -shared -Wl,-soname,libz.so.1" \ 
> ./configure --prefix=/usr --shared

不像其他的GNU軟件沒有--host，--build，--target選項，同時配置zlib庫。

你將不得不通過CHOST變量在配置zlib的

CHOST=powerpc-linux ./configure --prefix=/usr --enable-shared 
make 
make install
