Hi all,
I have a simple program which I can successfully compile with clang, using
MinGW's C/C++ Library:
#include <stdio.h>int main(int argc, char **argv) { printf("Hello
world!\n"); return 0; }
I am able to compile this with mingw-gcc successfully:
$ gcc test.c -o test
$ ./test
Hello world!
I am also able to compile it successfully using clang+mingw:
$ clang test.c -o test -target
$ ./test
Hello world!
However, if I make a small change to my program (include float.h), it
continues to compile with gcc but no longer compiles with clang:
#include <stdio.h>#include <float.h>int main(int argc, char **argv) {
printf("Hello world!\n"); return 0; }
$ gcc test.c -o test
$ ./test
Hello world!
$ clang test.c -o test -target x86_64-pc-windows-gnu
In file included from test.c:2:
In file included from C:\llvm\built\lib\clang\8.0.0\include\float.h:45:
C:\mingw64-8.1.0\x86_64-w64-mingw32\include\float.h:28:15: fatal
error: 'float.h' file not found
#include_next <float.h>
^~~~~~~~~
1 error generated.
Is there some configuration issue with clang or some missing command line
argument? Googling around a bit, it appears that the order of paths when
including float.h is important, but this is all supposed to be handled
internally by the clang driver.
Thanks,
Harry Wagstaff
