Bug #: 54283
Summary: [4.8 regression] build tools don't run after
cxx-conversion merge
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
CC: cr...@gcc.gnu.org, dnovi...@gcc.gnu.org
Host: *-*-solaris2.*
Target: *-*-solaris2.*
Build: *-*-solaris2.*
Since the merge of the cxx-conversion branch, Solaris bootstrap fails for me.
In stage 1, the build tools fail to run, e.g.
build/genmddeps /vol/gcc/src/hg/trunk/local/gcc/config/i386/i386.md >
tmp-mddeps
ld.so.1: genmddeps: fatal: libstdc++.so.6: open failed: No such file or
directory
make[3]: *** [s-mddeps] Killed
make[3]: *** Waiting for unfinished jobs....
I'm using a self-built gcc 4.4.2 as bootstrap compiler, installed into
/vol/gcc-4.4. In order to assure that the libstdc++.so.6 included there is
found,
I've so far been configuring with
--with-host-libstdcxx=\'-L/vol/gcc-4.4/lib -Wl,-Bstatic -lstdc++ -Wl,-Bdynamic
-lm\' --with-boot-ldflags=\'-static-libstdc++' -static-libgcc
-L/vol/gcc-4.4/lib\'
This is not enough after the conversion since the build tools don't use either
$BOOT_LDFLAGS or $HOST_LIBS.
The attached patch allowed the bootstrap to finish, but is obviously wrong
as-is
since it doesn't correctly distinguish between build and host tools. Having
never run a canadian cross myself, I'm not sure what the right approach is.
The first part (using $CC as linker instead of $CXX_FOR_BUILD) is necessary to
avoid linking with g++ which links with -lstdc++ on its own.
