current subversion (rev 115032) compiling issues

[Marco Trudel]

Hi list

I run into errors trying to compile the current subversion state. I 
compile with this command:

cd $GCC_BUILD_DIR
$GCC_SRC_DIR/configure --prefix=$GCC_OUT_DIR \
     --build=`$GCC_SRC_DIR/config.guess` --host=i686-pc-mingw32 
--target=i686-pc-mingw32 \
     --with-sysroot=$GCC_OUT_DIR/sys-root 
--with-build-sysroot=$GCC_OUT_DIR/sys-root \
     --enable-languages=c,c++,java \
     --with-as=$AS --with-ld=$LD --with-gcj=i686-pc-mingw32-gcj\
     --with-gnu-as --with-gnu-ld \
     --disable-nls --disable-debug --disable-shared --disable-checking \
     --enable-threads=win32 --disable-win32-registry 
--enable-sjlj-exceptions \
     --enable-libgcj
make

My compiler is a gcc 4.1.1 that compiles for i686-pc-mingw32.


The first problem is:
$GCC_SRC_DIR/libstdc++-v3/libsupc++/eh_personality.cc:434: error: 
'_Unwind_GetIPInfo' was not declared in this scope

Inserting #include "unwind-generic.h" before #include "unwind-cxx.h" 
solves this one. Inserting it anywhere after "unwind-cxx.h", won't work.
I don't know if this is correct or not, just solves the first problem...

Ok, next Problem:
$GCC_BUILD_DIR/i686-pc-mingw32/libstdc++-v3/include/limits:1011: error: 
'__FLT_HAS_DENORM__' was not declared in this scope
$GCC_BUILD_DIR/i686-pc-mingw32/libstdc++-v3/include/limits:1068: error: 
'__DBL_HAS_DENORM__' was not declared in this scope
$GCC_BUILD_DIR/i686-pc-mingw32/libstdc++-v3/include/limits:1125: error: 
'__LDBL_HAS_DENORM__' was not declared in this scope

Here I'm stuck because I'm unable to find the defining header or source 
file for these constants... Any ideas?

Marco

Hello Carlos

Your patch http://gcc.gnu.org/ml/gcc-patches/2005-12/msg00790.html seems 
to break cross-compiling for windows, see attached forwarded message.

The values of these definitions are computed by the compiler in gcc/c-cppbuiltins.c
(c_cpp_builtins).

Can you provide preprocessed source without macro expansion? I'm curious
why a Windows hosted toolchain doesn't call c_cpp_builtins.

Cheers,
Carlos.

Problem solved by updating the gcc I use to build the current subversion 
version to 4.2.0.
