LOC_CHECK_VERSION does 2 tests. First it tries to compile this program:
#include "confdefs.h"
#include <stdio.h>
#include <proj_api.h>
int main(void) {
FILE *fp = fopen("conftestdata","w");
fputs(PJ_VERSION, fp);
return 0;
}
Since PJ_VERSION is defined to be 449 or some similar number this will
produce a compiler warning. -Werror will make gcc act as if warning are
errors ==> compilation fails and this is never run. The macro then tries
to build this program:
#include "confdefs.h"
#include <stdio.h>
#include <$1>
int main(void) {
FILE *fp = fopen("conftestdata","w");
fprintf(fp, "%d", $2);
return 0;
}
which will compile in this case, and write the version to the
conftestdata file.
So to fix this all you need to do is introduce the -Werror flag to the
gcc commandline, which is trivial to do. All you need to do is modify
configure.in line 516. Add -Werror to the 5th parameter of the macro call.
Your line should now look something like this: (without linebreaks).
LOC_CHECK_VERSION(proj_api.h,PJ_VERSION,
External PROJ.4,proj_ver,$PROJINC -Werror,UNKNOWN)
I don't have a BSD to test on so I can't say if this works or not, but
on GNU/Linux PowerPC it does work.
