菜鸟面对nios2的编译问题崩溃中……

一个是我用nios2gcc编译一个写好的程序，提示如下：
nios2-linux-uclibc-gcc: unrecognized option `-shared'
/opt/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/../../../../nios2-linux-uclibc/lib/crt1.o(.text+0x10): In function `_start':
: undefined reference to `main'
/opt/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/../../../../nios2-linux-uclibc/lib/crt1.o(.text+0x14): In function `_start':
: undefined reference to `main'
collect2: ld returned 1 exit status

之后又对该编译器安装libjpeg，安装完之后发现include下竟然没有添加必须的那5个h文件，而安装过程却不报错……
然后生拷过去之后又提示我
/tmp/cc4aJtAS.o: In function `write_JPEG_file':
/tmp/cc4aJtAS.o(.text+0x20): undefined reference to `jpeg_std_error'
/tmp/cc4aJtAS.o(.text+0x3c): undefined reference to `jpeg_CreateCompress'

彻底崩溃中……
