Bug #: 50978
Summary: libgcc build fails - unable to find
unwind-arm-common.h
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mgret...@sourceware.org
CC: ramana.radhakrish...@arm.com, rearn...@.arm.com,
r...@gcc.gnu.org
Target: arm-none-eabi
Current SVN fails to build libgcc for an arm-none-eabi target because it can't
find unwind-arm-common.h:
In file included from
/work/upstream-checkouts/gcc/libgcc/config/arm/unwind-arm.c:24:0:
./unwind.h:31:31: fatal error: unwind-arm-common.h: No such file or directory
compilation terminated.
I think that the recent move of source from gcc/config to libgcc/config failed
to move the EXTRA_HEADERS line from gcc/config/arm/t-bpabi and
gcc/config/arm/t-symbian to libgcc/config/arm/t-bpabi and
libgcc/config/arm/t-symbian respectively.
However, making the naive change doesn't work as unwind-arm-common.h lives in
gcc/ginclude. Does the header have to move directory?
GCC is configured as follows:
/work/upstream-checkouts/gcc/configure --target=arm-master-eabi
--prefix=/work/builds/install
--with-sysroot=/work/builds/install/arm-master-eabi --with-newlib --with-gnu-as
--with-gnu-ld --enable-languages=c,c++ --with-gmp=.../linux_x86_64
--with-mpfr=.../linux_x86_64 --with-mpc=.../linux_x86_64
--with-libelf=.../linux_x86_64 --disable-lto --disable-shared --disable-nls
--disable-threads --disable-tls --enable-checking=yes --with-cpu=cortex-a9
--with-fpu=neon --with-float=softfp
Checked against gcc trunk SVN revision 180820
