Re: GCC-4.2-20060325 build failure on OpenBSD 3.9-current



Hello,


I've checkouted todays sources from trunk and I can confirm that the same failure also happens there.

Cheers,
Karel

Hello,


I'm trying to build GCC-4.2-20060325 on OpenBSD 3.9-current, but it fails with:

the compiler used for bootstrap is OpenBSD's gcc3.3.5. GCC 4.2 is configured with:


/home/karel/build/gcc-4.2-20060325/configure --prefix=/home/karel/usr/local/gcc-4.2-20060325 --enable-shared --enable-threads --disable-checking --disable-nls --enable-languages=c,c++

and it is build with:

gmake CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap-lean

If I understand this issue correctly, it seems GCC 4.2 stage1 compiler warns about missing sentinel and because of -Werror bootstrap fails. If this is true, then perhaps the same issue happen also on more supported platforms? (Linux/FreeBSD) If so, then my question is: is this already fixed on trunk?

Thanks,
Karel
