this time i downloaded the trunk I found /home/pc/pruebaBB/openwrt/build_dir/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2/gcc-linaro-4.8-2014.04-final/mips-openwrt-linux-uclibc/libgcc/libgcc-std.ver: 1830 __sync_fetch_and_xor_1 1831 __sync_fetch_and_nand_1 1832: __sync_add_and_fetch_1 1833 __sync_sub_and_fetch_1 1834 __sync_or_and_fetch_1 .... 1894 __sync_fetch_and_xor_16 1895 __sync_fetch_and_nand_16 1896: __sync_add_and_fetch_16 1897 __sync_sub_and_fetch_16 1898 __sync_or_and_fetch_16
i also added libatomic to to the package depends with no success. i couldn't find flags to enable atomic operations. has anybody had this issue? i don't know what i am missing 2015-01-21 6:30 GMT-02:00 Alexandru Ardelean <ardeleana...@gmail.com>: > I don't think libatomic exports that symbol. > It looks like that symbol should be in the standard gcc. > > You can try to add +libatomic to the DEPENDS section of czmq to see if > that helps. > But note that the libatomic package was added in this commit: > 7edd1ccebaf00db527fcbb1c6e75827722cfdc21 > > I'd say to pull a clone of the latest OpenWRT trunk and compare. > I don't know what the toolchain version of Barrier Breaker is. > > Here's on the latest trunk (I don't have a MIPS build right now): > build_dir/toolchain-x86_64_gcc-4.8-linaro_uClibc-0.9.33.2/gcc-linaro-4.8-2014.04-final/x86_64-openwrt-linux-uclibc/libgcc/libgcc-std.ver: > __sync_add_and_fetch_1 > build_dir/toolchain-x86_64_gcc-4.8-linaro_uClibc-0.9.33.2/gcc-linaro-4.8-2014.04-final/x86_64-openwrt-linux-uclibc/libgcc/libgcc-std.ver: > __sync_add_and_fetch_2 > build_dir/toolchain-x86_64_gcc-4.8-linaro_uClibc-0.9.33.2/gcc-linaro-4.8-2014.04-final/x86_64-openwrt-linux-uclibc/libgcc/libgcc-std.ver: > __sync_add_and_fetch_4 > build_dir/toolchain-x86_64_gcc-4.8-linaro_uClibc-0.9.33.2/gcc-linaro-4.8-2014.04-final/x86_64-openwrt-linux-uclibc/libgcc/libgcc-std.ver: > __sync_add_and_fetch_8 > build_dir/toolchain-x86_64_gcc-4.8-linaro_uClibc-0.9.33.2/gcc-linaro-4.8-2014.04-final/x86_64-openwrt-linux-uclibc/libgcc/libgcc-std.ver: > __sync_add_and_fetch_16 > > And the Changelog says: > > build_dir/toolchain-x86_64_gcc-4.8-linaro_uClibc-0.9.33.2/gcc-linaro-4.8-2014.04/libgcc/ChangeLog: > > 2014-01-25 Walter Lee <w...@tilera.com> > > Backport from mainline > 2014-01-25 Walter Lee <w...@tilera.com> > > * config/tilepro/atomic.c (pre_atomic_barrier): Mark inline. > (post_atomic_barrier): Ditto. > (__fetch_and_do): New macro. > (__atomic_fetch_and_do): Use __fetch_and_do. > (__sync_fetch_and_do): New macro. > (__sync_fetch_and_add_4): New function. > (__sync_fetch_and_sub_4): New function. > (__sync_fetch_and_or_4): New function. > (__sync_fetch_and_and_4): New function. > (__sync_fetch_and_xor_4): New function. > (__sync_fetch_and_nand_4): New function. > > > If you do find these symbols in your gcc toolchain, I'd say to look for > flags to enable them. > They might be disabled by default. > > > > > On Wed, Jan 21, 2015 at 7:10 AM, Santiago Regusci <santico...@gmail.com> > wrote: > >> Hi >> >> I am having trouble building a package czmq with barrier breaker for >> Mips24kc. >> i get src/.libs/libczmq.so: undefined reference to >> `__sync_add_and_fetch_8' >> do i have to add libatomic in the makefile toolchain. or has did anyone >> have a similar problem. >> >> how i can i fix this? >> >> thank you >> Santi >> >> >> _______________________________________________ >> openwrt-devel mailing list >> openwrt-devel@lists.openwrt.org >> https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel >> >> >
