以前也出现过这个问题,我在网上找了一下,照着下了一个libjpeg62-dev-arm.tar.gz的 包并解压成功,在lib中也可以查到相关库.但是再编译后虽然编译得比没有加库以前多点但还是有cannot find -ljpeg的问题,而且还多了skipping incompatible /usr/local/arm/3.3.2/arm-linux/bin/../lib/libjpeg.a when searching for -ljpeg等这些不兼容问题.
  请问各位高手,这个问题该如何解决呢?
  非常急!!!

mozilla

file /usr/local/arm/3.3.2/arm-linux/bin/../lib/gcc-lib/ar
m-linux/3.3.2/../../../../arm-linux/lib/libjpeg.so

看看是不是arm库

mozilla

执行file /usr/local/arm/3.3.2/arm-linux/bin/../lib/gcc-lib/arm-linux/3.3.2/../../../../arm-linux/lib/libjpeg.so
把打印信息贴出来

libjpeg62 是个arm库,我在网上下的时候后面括号注明了的

mozilla

虽然是arm库，但不一定跟你的兼容。

这不是arm库，intel 80386
