Hi, I have a problem when build a mipsel n32 cross compiler uclibc toolchain on a CentOS4/X86_64 host. The buildroot I use is the snapshot buildroot-20081210.tar.bz2. Firstly I issue "make menuconfig" under buildroot directory. Among the target options, I choose "mipsel, mips4, n32". Among the toolchain options, I choose "Enable multilib support". Secondly, I issue "make uclibc-menuconfig" under buildroot. In the "Target Architecture Features and Options", I adjust the miss-guessed "Target ABI" from O32 to N32. Other options are left unchanged. Then I type "make" to build. I find binutils-2.19, gcc-4.2.4-initial are all successfully built. But when building uClibc-0.9.30, the following error happens:
.... AS ldso/ldso/mips/resolve.oS AR cr ldso/ldso/ld-uClibc_so.a STRIP -x -R .note -R .comment ldso/ldso/ld-uClibc_so.a LD ld-uClibc-0.9.30.so collect2: ld terminated with signal 11 [Segmentation fault] /home/jczhang/research/buildroot/build_mipsel/staging_dir/usr/lib/gcc/mipsel-linux-uclibc/4.2.4/../../../../mipsel-linux-uclibc/bin/ld: ldso/ldso/ld-uClibc_so.a(ldso.oS): ABI is incompatible with that of the selected emulation /home/jczhang/research/buildroot/build_mipsel/staging_dir/usr/lib/gcc/mipsel-linux-uclibc/4.2.4/../../../../mipsel-linux-uclibc/bin/ld: failed to merge target specific data of file ldso/ldso/ld-uClibc_so.a(ldso.oS) /home/jczhang/research/buildroot/build_mipsel/staging_dir/usr/lib/gcc/mipsel-linux-uclibc/4.2.4/../../../../mipsel-linux-uclibc/bin/ld: ldso/ldso/ld-uClibc_so.a(resolve.oS): ABI is incompatible with that of the selected emulation /home/jczhang/research/buildroot/build_mipsel/staging_dir/usr/lib/gcc/mipsel-linux-uclibc/4.2.4/../../../../mipsel-linux-uclibc/bin/ld: failed to merge target specific data of file ldso/ldso/ld-uClibc_so.a(resolve.oS) ldso/ldso/ld-uClibc_so.a(ldso.oS): In function `_start': ldso.c:(.text+0x20): undefined reference to `_DYNAMIC' make[1]: *** [lib/ld-uClibc.so] Error 1 make[1]: Leaving directory `/home/jczhang/research/buildroot/toolchain_build_mipsel/uClibc-0.9.30' make: *** [/home/jczhang/research/buildroot/toolchain_build_mipsel/uClibc-0.9.30/lib/libc.a] Error 2 I checked ldso.oS and gcc library such as crt1.o ect. As expected, they are all n32 ELF files. So, why there is the "ABI is incompatible ..." error? Any help is appreciated. Thanks! _______________________________________________ uClibc mailing list uClibc@uclibc.org http://busybox.net/cgi-bin/mailman/listinfo/uclibc
