[Python-Dev] How to make _sre.c compile w/ C++?

Tue Apr 18 03:27:07 CEST 2006

I checked in a number of minor changes this evening to correct various
problems compiling Python with a C++ compiler, in my case Apple's version of
g++ 4.0. I'm stuck on Modules/_sre.c though. After applying this change:
Index: Modules/_sre.c

 ptr = getstring(ptemplate, &n, &b);
 if (ptr) {
 if (b == 1) {
- literal = sre_literal_template(ptr, n);
+ literal = sre_literal_template((SRE_CHAR *)ptr, n);
 } else {
 #if defined(HAVE_UNICODE)
- literal = sre_uliteral_template(ptr, n);
+ literal = sre_uliteral_template((Py_UNICODE *)ptr, n);
 #endif
 }
 } else {
I am left with this error:
../Modules/_sre.c: In function 'PyObject* pattern_subx(PatternObject*, PyObject*, PyObject*, int, int)':
../Modules/_sre.c:2287: error: cannot convert 'Py_UNICODE*' to 'unsigned char*' for argument '1' to 'int sre_literal_template(unsigned char*, int)'
During the 16-bit pass, SRE_CHAR expands to Py_UNICODE, so the call to
sre_literal_template is incorrect. Any ideas how to fix things?
As clever as the two-pass compilation thing is, I must admit it confuses me.
Thx,
