[LLVMdev] LLVM-GCC and Symbian

[Wim Vander Schelden]

Hi,

I noticed that there is some kind of reference to Symbian support in
LLVM-GCC, and I'm trying to find out more about it. I configured llvm-
gcc-4.2-2.5 using:

> ../configure --prefix=/opt/stow/llvm-gcc-2.5/ --enable-llvm=/home/wim/Documents/Sources/llvm-2.5/OBJ_ROOT/ --disable-bootstrap --disable-multilib --enable-checking --target arm-none-symbianelf --enable-languages=objc,c,c++ --disable-libada

At this point, everything seems to work, with the following warning
coming up:

> *** This configuration is not supported in the following subdirectories:
>     gnattools target-libmudflap target-libgomp target-libffi target-zlib target-libjava target-libiberty target-libada target-libgfortran zlib target-boehm-gc
>    (Any other directories should still work fine.)

But when I try to build, I get the following error message:

> gcc -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -fno-common -DHAVE_CONFIG_H -DGENERATOR_FILE -I. -Ibuild -I../../gcc -I../../gcc/build -I../../gcc/../include -I../../gcc/../libcpp/include  -I../../gcc/../libdecnumber -I../libdecnumber -I/home/wim/Documents/Sources/llvm-2.5/OBJ_ROOT//include -I/home/wim/Documents/Sources/llvm-2.5/include -DENABLE_LLVM -I/home/wim/Documents/Sources/llvm-2.5/OBJ_ROOT/../include  -D_DEBUG  -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS   -o build/gencondmd.o build/gencondmd.c

I was wondering if this is because of the Symbian target or just a
universal ARM issue.

Also, since I find so little about Symbian and LLVM support, is there
any chance for LLVM to actually build working Symbian binaries?

Kind regards,

Wim
