[PATCH 3/3] Use the tail name as the output name of compile.

[Yao Qi <yao at codesourcery dot com>]

Hi,
I find this error in gdb.log:

$ ./solib-symbol-main
/home/yqi/solib-symbol-main: error while loading shared libraries:
a.out: cannot open shared object file: No such file or directory

and it is caused by the compilation option '-o a.out',

i686-mingw32-gcc.exe  solib-symbol-lib.c.o  -shared
-Wl,--out-implib,solib-symbol-lib.so.a -g  -Wl,-Bsymbolic
set_unbuffered_mode_saved.o -lm  -o a.out

The info of ld explains about '--out-implib' that the import lib
should be called '*.a'.

`--out-implib FILE'
     The linker will create the file FILE which will contain an import
     lib corresponding to the DLL the linker is generating. This import
     lib (which should be called `*.dll.a' or `*.a' may be used to link
     clients against the generated DLL; this behaviour makes it
     possible to skip a separate `dlltool' import library creation step.
     [This option is specific to the i386 PE targeted port of the
     linker]

the fix is to change '-o a.out' to '-o solib-symbol-lib.so',

i686-mingw32-gcc.exe  solib-symbol-lib.c.o  -shared
-Wl,--out-implib,solib-symbol-lib.so.a -g  -Wl,-Bsymbolic
set_unbuffered_mode_saved.o -lm  -o solib-symbol-lib.so

This is what this patch does.

	* lib/future.exp (gdb_default_target_compile): Use tail name of
	$destfile as the output name of compile.  Move the generated
	file to $destfile on build.
