Hi,
I'm trying to build an arm-linux-gnueabi toolchain using:
binutils-2.16.1 gcc-4.1.0 linux-2.6.16.1 kernel headers glibc-2.4 glibc-ports-2.4
I applied the patches posted by Khem Raj to crosstool-0.42: http://sourceware.org/ml/crossgcc/2006-03/msg00090.html
The configure for build-glibc-startfiles fails with: "configure: error: compiler support for __thread is required"
If I try to compile a simple test program: "extern __thread int i;" with the gcc-core compiler it gives the error: "test-__thread.c:1: error: thread-local storage not supported for this target"
The configuration for the gcc-core compiler is:
[snip]
arm-linux-gnueabi-gcc -v
Using built-in specs.
Target: arm-linux-gnueabi
Configured with: ../gcc-4.1.0/configure --target=arm-linux-gnueabi --host=i686-host_pc-linux --prefix=/home/stevep/work/tools/tcf/glibc-2.4-work/gcc-core-prefix
--with-local-prefix=/opt/crosstool/gcc-4.1.0-glibc-2.4/arm-linux-gnueabi/arm-linux-gnueabi
--disable-multilib --with-newlib --disable-libunwind-exceptions --without-headers --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c --disable-shared --with-tls --with-__thread
Thread model: posix
gcc version 4.1.0
[/snip]
I tried different configuration combinations for gcc, but it doesn't seem to make any differnce as I get the same error every time I try to compile the test program. :-(
Is thread local storage supported for arm eabi targets in gcc-4.1.0, or have I configured the core compiler incorrectly? Or is there a patch needed to gcc?
I've been pulled away by other priorities but have a look at my earlier posts to crossgcc. I'll get back to looking at this as soon as I can. Maybe we'll get further than I have alone.
Steve
