我必须承认我的问题与 lgfortran找不到非常相似，但是因为我是Linux的新手，所以我需要更多帮助，但在上面的文章中找不到我想要的东西.
I must admit that my question can be considered to be very similar to lgfortran not found, but as I am a newbie in Linux I need more help and I couldn't find what I am looking for in the above post.
我安装了一个新的Linux Mint Debian版本，我正在尝试为Ada制作一个lapack绑定.
I have a fresh linux mint Debian edition installed and I am trying to make a lapack binding for Ada to work.
如果我检查gfortran，我会得到:
If I check for gfortran, I get:
gfortran-4.6 -v
Using built-in specs.
COLLECT_GCC=gfortran-4.6
COLLECT_LTO_WRAPPER=/usr/lib/gcc/i486-linux-gnu/4.6/lto-wrapper

如果我locate libgfortran，我得到:

/usr/lib/gcc/i486-linux-gnu/4.6/libgfortran.so

/var/lib/dpkg/info/libgfortran3.shlibs
/var/lib/dpkg/info/libgfortran3.symbols
运行makefile时，我得到:
make all
gcc -c cxbbase.ads
gcc -c cxbbase.ads
gnatmake cxbi.adb -largs ifinc.o -lgfortran -lm
gnatbind -x cxbi.ali
gnatlink cxbi.ali ifinc.o -lgfortran -lm
/usr/gnat/libexec/gcc/i686-pc-linux-gnu/4.5.3/ld: cannot find -lgfortran
collect2: ld returned 1 exit status
gnatlink: error when calling /usr/gnat/bin/gcc
gnatmake: *** link failed.
make: *** [cxbi] Error 4
我正在使用的makefile在这里:
The makefile that I'm using is here:

由于我是Linux的新手，如果能获得有关如何解决此问题的详细说明，我将不胜感激.
As I am very new to Linux, I would be very grateful if I could get detailed instructions on how to fix this.
谢谢
推荐答案
解决方案是将/usr/lib/gcc/i486-linux-gnu/4.6转换为LIBRARY_PATH.此解决方案在Comp Lang Ada上进行了讨论:
The solution was to /usr/lib/gcc/i486-linux-gnu/4.6 to LIBRARY_PATH. This solution is discussed here on Comp Lang Ada:
