libpng 크로스 컴파일 하기 - libpng cross compile

머.. libjpeg가 그랬듯이 libpng도 별 건 없다.

$ more INSTALL

Installing libpng version 1.2.38 - July 16, 2009 On Unix/Linux and similar systems, you can simply type     ./configure [--prefix=/path]     make check     make install and ignore the rest of this document.

물론 크로스 컴파일이므로
make check는 "cannot execute binary file" 메시지를 출력하면서 중단된다.
