[Rdkit-devel] Anyone building the cartrdige with GCC 4.6.2 in a 32 bit env?

[Gianluca S. <gi...@gm...>]

Building the cartridge fails with gcc 4.6.2 in my 32bit build root like this:

++ -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686
-mtune=atom -fasynchronous-unwind-tables -DLINUX_OOM_ADJ=0 -Wall
-Wpointer-arith -Wendif-labels -Wformat-security -fno-strict-aliasing
-fwrapv -fexcess-precision=standard -fpic -Wno-deprecated
-Wno-unused-function -I/usr/local/include
-I/builddir/build/BUILD/RDKit_2011_12_1/Code -DRDKITVER='"004000"'
-I/usr/local/include -I/builddir/build/BUILD/RDKit_2011_12_1/Code
-DRDKITVER='"004000"'  -I. -I. -I/usr/include/pgsql/server
-I/usr/include/pgsql/internal -D_GNU_SOURCE -I/usr/include/libxml2
-c -o adapter.o adapter.cpp
cc1plus: sorry, unimplemented: -fexcess-precision=standard for C++
make: *** [adapter.o] Error 1

while the same 64 bit build completes without errors.

Did anyone experience the same behavior?

According to the gcc manual,  -fexcess-precision defaults to "fast".
Is there a specific reason to deviate from that?
