Successful bootstrap for GCC 7.1.0 on Windows 10
Hi GCC team,
I have successfully built GCC 7.1.0 on Windows 10 x64 with GCC 6.3.0
and Binutils 2.27.
Output of src/config.guess: x86_64-pc-mingw64
Output of gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=c:/mingw64/bin/../libexec/gcc/x86_64-w64-mingw32/7.1.0/lto-w
rapper.exe
Target: x86_64-w64-mingw32
Configured with: ../configure --build=x86_64-w64-mingw32 --host=x86_64-w64-mingw

ble-languages=c,c++ --enable-libstdcxx-time --enable-threads=win32 --enable-liba
tomic --enable-fully-dynamic-string
Thread model: win32
gcc version 7.1.0 (GCC)
Notes:
1. I can't build GMP, MPFR, MPC and ISL in-tree.
2. I was getting this error message in stage 2:
configure: error: in `/c/mingw64/src/build/gcc':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
Workaround:
export CPP=/bin/cpp
And manually replace all occurrences of "/lib/cpp" in
src/gcc/configure with "/bin/cpp"
3. For some reasons I do not know, stage 2 can't find Mingw64 runtime
includes and libraries
even though I already ran these commands in target root (standard
procedure for Windows,
used to work when I built GCC 6.3.0):
cp -r x86_64-w64-mingw32/lib x84_64-w64-mingw32/lib64
cp -r x86_64-w64-mingw32 mingw
mkdir -p gcc-6.3.0/gcc/winsup/mingw
cp -r x86_64-w64-mingw32/include gcc-6.3.0/gcc/winsup/mingw
Workaround:
export CPATH=/c/mingw64/mingw/include
export LIBRARY_PATH=/c/mingw64/mingw/lib
4. I was building GCC with make BUILD_CONFIG=bootstrap-lto and got
error messages about missing
stpcpy and sys_siglist during linking.
Workaround:
Apply the following patch.

Not immediately, usually we made a release around the x.2 release from the latest release branch or a little bit earlier, so maybe in late June or in July? Jakub

add GCC 7.1 to Bugzilla?
Now that GCC 7.1 has been released, should 7.1 be added to the versions in Bugzilla so that bugs can be assigned the right version? (I'm using 7.0 in the meantime.) Or is there someone not on this list I might need to bug with this request? Thanks Martin

You're right, I forgot about the .0 at the end and Bugzilla didn't like it. Thanks and sorry for the noise. Martin
