Bug ID: 70200
Summary: builing gcc with -lfto without libunwind
Product: gcc
Version: 5.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: dilyan.palauzov at aegee dot org
Target Milestone: ---
I have the newest gcc-5 (commit e0f9303ca2e71). In my /etc/config.site is
written:
export CFLAGS="-pipe -O3 -fno-fat-lto-objects -flto"
export CXXFLAGS="-pipe -O3 -fno-fat-lto-objects -flto"
export enable_silent_rules=yes
export LDFLAGS="-Wl,-z,relro,-O1,-s -flto=24"
I use binutils 2.26.51.20160310 (ld.bfd, gas, etc).
Then I do:
/git/gcc/configure --enable-host-shared --enable-threads=posix
--with-arch=haswell --enable-targets=all --enable-nls
--with-linker-hash-style=gnu --with-system-zlib --disable-multilib
--enable-languages=c,c++,jit,lto
and at stage_current=stage_last=2 I get "undefined reference to
`_Unwind_Resume'", as listed below.
Please update the documentation under INSTALL, that in order to avoid this
problem, libunwind has to be installed and configured with "./configure
--enable-cxx-exceptions".
Not passing "-fno-fat-lto-objects -flto" to CFLAGS/CXXFLAGS does not show the
problem, even if libunwind is not installed.
