c++ - Incompatibilities with DMC-headers and preprocessor?
Hi, I probably ran into several incompatibilities with the own DMC headers and its preprocessor ... just take a look at the following: -------------------------------------------------------------------------------- 1. the following combination of src/options doesn't work Sample: #include <stdbool.h> struct test { bool t_bool; }; int main(int argc, char **argv) { struct test x; x.t_bool = true; return (x.t_bool ? 1 : 0); } I compiled it with the following command: sc test0001.c -cpp -mn -C -WA -S -3 -a8 -c -otest0001.obj This is explainable and might be correct ... ?!? The example above can be compiled when I remove #include <stdbool.h> 2. Preprocessor recognizes statements that aren't of our interest Sample: #if 0 #warning fubar #endif The "#warning" statement should be ignored ... 3. strict ANSI support broken? Sample: #include <stdlib.h> int main(int argc, char**argv) { return 0; } Compiled with: sc test0002.c -A -cpp -mn -C -WA -S -3 -a8 -c -otest0002.obj --------------------------------------------------------------------------------- Anyway, I 'm glad to see that the work on DMC (Symantec C++) continues and I like the new features and now I think about using this compiler in my next projects ...
