I did a "git pull" from the PostrgeSQL repository. then did a "make ecpg"
in the src/interfaces/ecpg directory. I then used the new ecpg on the
example code, followed by a gcc compile. The compile went fine. I made a
slight change to the code, just because to be:
#include <stdio.h>
EXEC SQL TYPE t_char_10 IS char[10];
EXEC SQL TYPE t_char_10d IS struct { char data[10];};
EXEC SQL TYPE char_ptr IS char reference;
int main()
{
t_char_10 string10;
int len=3Dsizeof string10;
printf("size is: %d\n",len);
int status =3D 0;
return status;
}
And then:
ecpg -c test-ecpg.pgc && gcc test-ecpg.c && ./a.out
which printed:
size is 10
Looks good to me on Linux, Fedora 22 x86_64.
