Apparently not. :)
I just tried the following with an svn checkout of trunk (r75433), on OS X 10.6:
dickinsm$ CC='gcc -DWITHOUT_COMPLEX' ./configure && make
The build fails with:
gcc -DWITHOUT_COMPLEX -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall
-Wstrict-prototypes -I. -IInclude -I./Include -DPy_BUILD_CORE -o
Python/compile.o Python/compile.c
Python/compile.c: In function ‘compiler_add_o’:
Python/compile.c:914: error: ‘Py_complex’ undeclared (first use in
this function)
Python/compile.c:914: error: (Each undeclared identifier is reported only once
Python/compile.c:914: error: for each function it appears in.)
Python/compile.c:914: error: expected ‘;’ before ‘z’
Python/compile.c:931: warning: implicit declaration of function
‘PyComplex_Check’
Python/compile.c:937: error: ‘z’ undeclared (first use in this function)
Python/compile.c:937: warning: implicit declaration of function
‘PyComplex_AsCComplex’
make: *** [Python/compile.o] Error 1
Mark
Postscript: the above compilation failure is easily fixed. The next
failure is:
gcc -DWITHOUT_COMPLEX -u _PyMac_Error -o python.exe \
Modules/python.o \
libpython2.7.a -ldl
Undefined symbols:
