gcc linking / libtools / building stuff

[Bruce Labitt]

I'm trying to get a program I wrote to link with FFTW.  This is being 
done on gcc on linux.  I built FFTW from source.  When I did make 
install there was a message in the output that said I needed to use 
libtools or one of the following...  a rather long list followed.  If 
you want to know what it was I have to go look for it.  When I went to 
find documentation on libtools I got 100 pages of "stuff".  Why would I 
want to use libtools?  I don't even know what it is really for.  All I 
want is the compiler to be able to find the libraries I just built so I 
can link it to my stuff.

So I tried to just build it from the command line and this is what I got.

$ gcc main_tb_fftw.cpp -otbfft -I/usr/local/include -L/usr/local/lib 
-lfftw3 -lm
/tmp/ccJMISfw.o: In function 
`__static_initialization_and_destruction_0(int, int)':
main_tb_fftw.cpp:(.text+0x23): undefined reference to 
`std::ios_base::Init::Init()'
/tmp/ccJMISfw.o: In function `__tcf_0':
main_tb_fftw.cpp:(.text+0x6c): undefined reference to 
`std::ios_base::Init::~Init()'
/tmp/ccJMISfw.o:(.eh_frame+0x12): undefined reference to 
`__gxx_personality_v0'
collect2: ld returned 1 exit status

So what does all that mean???  The program did compile and link using 
Dev-C++ (gcc) on windoze.  It looks like it can't find iostream ?  I 
have that included in main_tb_fftw.

Thanks!
