Hi,

I need this for parallel build and libstdc++.so.

Thanks.

What about the rs6000/linux patch, it does the same thing...

Anyone know?

G++ linker warnings on i386-cygwin32

[Jan-Jaap van der Heijden]

I built egcs-970825 as an i386-linux-gnulibc1 -> i386-cygwin32 cross.

I noticed it installs the collect2 linker, though cygwin32 uses GNU ld.

Most annoyning, compiling a trivial C++ program:

----------------------
#include <iostream.h>

int main(void)
{
  cout << "Hello World!\n";
}
----------------------

gives me a few screens of linker warnings:

Removing the collect2 linker doesn't help. Anybody got a clue?

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead.  -- RFC1925.

Until we have that code I'm pulling the alpha/linux.h patch out.

Re: A gcc Makefile patch.

[Jim Wilson]

	I need this for parallel build and libstdc++.so.

	Tue Aug 26 07:43:18 1997  H.J. Lu  (hjl@gnu.ai.mit.edu)

	* Makefile.in (check-g++): Set/export LD_LIBRARY_PATH if
	necessary.
	(testsuite/site.exp): New target.
	(check-gcc, check-g++): Depend on testsuite/site.exp.
	Don't stop for failure.

I have installed this, except for the LD_LIBRARY_PATH stuff.

Setting LD_LIBRARY_PATH to ../libstdc++ will not work for any target
using multilibs, so we need a more general solution.  I think the
only way to make this work is to fix the problem in dejagnu, because it
is only in dejagnu that we know what the correct pathname to libstdc++.so is.
