I'm updating the binary builds to GCC 4.9 right now and found a weird new bug: I had to update the mingw64 headers and they now #define strtod __strtod in stdlib.h (or maybe they always did and the problem didn't show for some reason, I don't know). As a result, our 'Port::strtod' is hijacked into 'Port::__strtod'. So far, no real problem. But it seems d-port.cc does not include the stdlib.h header so the define is not effective there. As a result I get this link error when linking cc1d: ------------------ d/lexer.dmd.o: In function `ZN5Lexer6inrealEP5Token': /home/build/tmp/i686-w64-mingw32/.build/src/gcc-4.9.0/gcc/d/dfrontend/lexer.c:2360: undefined reference to `Port::__strtod(char const*, char**)' collect2: error: ld returned 1 exit status i686-gdcproject-mingw32-nm d/lexer.dmd.o | grep strto U __ZN4Port6strtofEPKcPPc U __ZN4Port7strtoldEPKcPPc U __ZN4Port8__strtodEPKcPPc i686-gdcproject-mingw32-nm d/d-port.glue.o | grep strto 00000404 T __ZN4Port6strtodEPKcPPc 0000038a T __ZN4Port6strtofEPKcPPc 0000047e T __ZN4Port7strtoldEPKcPPc ------------------ I propose adding ------------------ // MinGWs stdlib.h defines strtod to __strtod. // Depending on whether this header is included our function name changes... #ifdef strtod #undef strtod #endif ------------------ to dfrontend/port.h. What do you think Iain?
