compiling libgomp separately

[Robert Oeffner]

Hi,
I'm trying to port GCC 4.4.0 to interix. I have some issues with libgomp. To 
save time rather than bootstrapping GCC each time I make a change I would 
like to compile libgomp separately to make my amendments take effect. So I 
copied gcc-4.4.0/libgomp/ to a separate folder mylibgomp/ and from there ran 
../gcc-4.4.0/libgomp/configure and gmake in that folder. libgomp does 
compile object files but no library files, libgomp.so and libgomp.a. Are 
there anyone who could point out what I'm doing wrong?

Many thanks,

Rob

  You can't use the subdirectory configures like that, they depend on the
top-level configure to pass stuff down to them.  What you need to do is do a
full bootstrap once, then cd into your $objdir/$target/libgomp and just run a
"make all" at that level.

    cheers,

Configure with --disable-bootstrap so that gcc won't try to bootstrap 
when you type make.  You can also use "make all-target-libgomp" to just 
build libgomp and everything it depends on (which probably includes gcc).
