Bug ID: 90653
Summary: --with-build-sysroot= not honored for ./configure C
compiler checks.
Product: gcc
Version: 8.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: kallisti5 at unixzen dot com
Target Milestone: ---
After updating from gcc 7.3.x to 8.3.x, the early stage of our bootstrap is no
longer finding our provided sysroot.
Build flags:
CFLAGS="-O2 -U_FORTIFY_SOURCE" CXXFLAGS="-O2" ./configure \
--build=$buildMachineTriple
--host=$effectiveTargetMachineTriple \
--target=$effectiveTargetMachineTriple --prefix=$installDir \
--libexecdir=$installDir/lib --mandir=$manDir --docdir=$docDir
\
--disable-nls --enable-shared --disable-plugin \
--enable-version-specific-runtime-libs \
--enable-languages=c,c++ --enable-lto --enable-frame-pointer \
--enable-threads=posix --enable-tls \
--with-pkgversion=$(echo $portVersion | cut -c 7-) \
--with-sysroot=/ \
--with-build-sysroot=$sysrootLocation \
--with-threads=posix \
--with-default-libstdcxx-abi=gcc4-compatible \
--disable-libstdcxx-pch \
$sysrootLocation is:
/work/generated.ppc/objects/haiku/ppc/packaging/repositories/HaikuPortsCross-build/sys-devel/gcc_bootstrap/work-8.3.0_2019_05_24/boot/cross-sysroot/ppc
With this, we get:
"error: C compiler cannot create executables"
Our startfile specs are valid...
#define STANDARD_STARTFILE_PREFIX_1 "/boot/system/non-packaged/develop/lib/"
#define STANDARD_STARTFILE_PREFIX_2 "/boot/system/develop/lib/"
...and we have a valid early build sysroot:
root@9e90f9304b75:/work/generated.ppc# find
/work/generated.ppc/objects/haiku/ppc/packaging/repositories/HaikuPortsCross-build/sys-devel/gcc_bootstrap/work-8.3.0_2019_05_24/boot/cross-sysroot/ppc

However, we get gcc executed during the configure stage and receive:
/work/generated.ppc/cross-tools-ppc/lib/gcc/powerpc-apple-haiku/8.3.0/../../../../powerpc-apple-haiku/bin/ld:
cannot find crti.o: No such file or directory

I'm not sure if this is a autoconf bug, or a gcc bug. I think *maybe* autoconf
handles the "generate valid executables with C compiler" phase?
