64位Linux下安装 jpeg 时出现错误

在64位Linux下安装 jpeg 时出现错误

tar xzf jpegsrc.v6b.tar.gz -C /usr/local
cd /usr/local/jpeg-6b
./configure --enable-shared
make
make install

执行到./configure –enable-shared一步时提示：

checking host system type… Invalid configuration `x86_64-unknown-linux-gnu ‘: machine `x86_64-unknown ‘ not recognized

checking build system type… Invalid configuration `x86_64-unknown-linux-gnu ‘: machine `x86_64-unknown ‘ not recognized

configure: error: libtool configure failed

找了一下解决方案，贴出：

cp /usr/share/libtool/config/config.guess .
cp /usr/share/libtool/config/config.sub .
./configure --enable-shared --enable-static --enable-lib64 --libdir=/usr/lib64
make

make install
