That would seem to be the correct behavior for the -static option. You should have seen the Make output on your console, which might have included the libraries that were linked to the code. That is what the -M flag does for you. I used to use it to generate a make file rule, but when I moved to IDE's I quite using Makefile systems, most of them have a predefined project file of one kind or another which performs the functions of Make or actually uses make in the background. You can also use the -static option to only include the libgcc so that you aviod the issues of libgcc not being updated and not having the current calls implemented. The other shared library calls seldom change, especially for a program like hello (I am assuming this is the "hello world" program.Mike McCarty wrote: > I have some tools which I use on my machine, and which I wish > also to use on my GF's machine.

More experimentation shows that this may have done it... $ gcc -Wl,-M -o hellostatic hello.c -static 2>&1 | less $ ls -l hello* -rwxrwxr-x 1 jmccarty jmccarty 4716 Oct 17 2005 hello -rw-rw-r-- 1 jmccarty jmccarty 109 Jul 11 2005 hello.c -rwxrwxr-x 1 jmccarty jmccarty 126458 Jul 11 2005 hello.exe -rwxrwxr-x 1 jmccarty jmccarty 390403 Jun 5 08:07 hellostatic I tried several other things, but this is the one which made the executable actually grow. Brief perusal of the map seems to indicate that the libs got included into the image.
