Bug#677972: cpl: fftw not found on ia64, s390x
Source: cpl Version: 6.1.1-1 On ia64 and s390x, fftw is not detected during configure. Therefore the FFTW part is not available on these platforms. configure reports: [...] checking for libwcs... libraries /usr/lib/ia64-linux-gnu, headers /usr/include checking for a libwcs version = 4.4.4... 4.13.4 checking for fftw (normal-precision)... libraries /usr/lib/ia64-linux-gnu, headers /usr/include checking for a fftw (normal-precision) version = 3.1.2... no configure: WARNING: Installed normal-precision fftw (4.13.4) is too old checking for fftw (single-precision)... libraries /usr/lib/ia64-linux-gnu, headers /usr/include checking for a fftw (single-precision) version = 3.1.2... no configure: WARNING: Installed single-precision fftw (4.13.4) is too old! checking for ANSI C header files...

It is still unclear whether this is a problem with the fftw installation on these platforms, or a bug in the configure script of cpl. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#677972: cpl: fftw not found on ia64, s390x
The detection failure is due to the following program run by configure
(from m4/cpl.m4):
--8
#include stdio.h
#include stdlib.h
#include string.h
#include fftw3.h
int main(void) {
char vmin[] = 3.1.2;
char *vstr= strdup(fftw_version);
char *vlib= vstr;
char *suffix = NULL;
int min_major = 0;
int min_minor = 0;
int min_micro = 0;
int lib_major = 0;
int lib_minor = 0;
int lib_micro = 0;
vlib = strchr(vstr, '-') + 1;
suffix = strrchr(vlib, '-');
if (suffix) {
*suffix = '\0';
}
sscanf(vmin, %d.%d.%d, min_major, min_minor, min_micro);
sscanf(vlib, %d.%d.%d, lib_major, lib_minor, lib_micro);
FILE* f = fopen(conftest.out, w);
fprintf(f, %s\n, vlib);
fclose(f);
free(vstr);
if (lib_major min_major) {
return 1;
} else {
if (lib_major == min_major) {
if (lib_minor min_minor) {
return 1;
} else {
if (lib_minor == min_minor) {
if (lib_micro min_micro) {
return 1;
}
}
}
}
}
return 0;
}
--8
Since the output prints with the version number 4.13.4 the wcslib
version number, I suspect that the program is actually run on these
platform -- either it silently crashes, or it does not compile at all.
