Re: Question: link to wrong library

I think you may need LD_LIBRARY_PATH

Hi. I'm new to guile.  I compiled it from source without `make install`. 

I write a simple C file and use the flowing command to compile it.

    `gcc -pthread -I. -L ./libguile/.libs -lguile-2.2  -lgc test.c`

it successed. but the a.out is always link to my system guile library.

   $ ldd ./a.out 

linux-vdso.so.1 (0x00007fffc259b000)

libguile-2.2.so.1 => /usr/lib/libguile-2.2.so.1 (0x00007fa90f9fe000)

libgc.so.1 => /usr/lib/libgc.so.1 (0x00007fa90f794000)

even I do the flowing:

$ cp libguile/.libs/libguile-2.2.so.1.3.0  libguile/.libs/libguile-2.5.so

$ gcc -pthread -I. -L ./libguile/.libs -lguile-2.5  -lgc test.c  # it successed

$ ldd ./a.out 

linux-vdso.so.1 (0x00007ffd283e0000)

libguile-2.2.so.1 => /usr/lib/libguile-2.2.so.1 (0x00007f83c71cc000)

libgc.so.1 => /usr/lib/libgc.so.1 (0x00007f83c6f62000)

Could someone give me some tips.  Thanks.
