Subject: [9front] Bug in APE pcc
Date: Sun, 1 Oct 2023 10:52:17 +0900 [thread overview]
Message-ID: <CAN4cm2uyd=hZf2f+CiFYWr8_5E26qiZ5CG_3COADm5qOALLL9g@mail.gmail.com> (raw)
Try:
------ BEGIN ----
#include <stdio.h>
#include <math.h>
int
main(int argc, char *argv[])
{
printf("log2 %f\n",log2(8));
printf("log10 %f\n",log10(100));
return 0;
}
----- END ----
The result is
hebe# pcc -o a1 a1.c
/usr/arisawa/doc/ape/intro/a1.c:7[stdin:321] function not declared: log2
hebe#
hebe# ape/psh
$ cc -o a1 a1.c
$ a1
log2 0.000000
log10 2.000000
How to fix the problem?
add
extern double log2(double);
to
/amd64/include/ape/math.h
then OK.
