I have some F77 code that compiled fine using the GNU autotool environment,=
having the
macro AC_PROG_F77 in configure.ac.
The project compiles fine on Linux Ubuntu 14.04 LTS (gfortran version 4.8).=
But since a
while it doesn't on FreeBSD 9.2/10/11 anymore!
I miss something here and I do not know what.
I use Fortran not on a regular basis, so this problem caught me, again, on =
the wrong foor.
Further details see below.
Regards,
Oliver

Before I start reporting the issue, this is what I have installed as the ba=
se:
language ports:
gcc-4.7.3_1
gcc48-4.8.3.s20140424
autotools:
autoconf-2.69
autoconf-wrapper-20131203
autoconf213-2.13.000227_6
autogen-5.12_2
automake-1.14
automake-wrapper-20131203
automake14-1.4.6_6
automoc4-0.9.88_3
autotools-20130627
As shown below, the autotools are incapable of detecting installed compiler=
s. As also
reported below, gfortran48 miscompiles (while the gfortran 4.8.2 on Ubuntu =
14.04 LTS does
not have a problem with the very same code!) and gfortran47 is missing obvi=
ously the
correct path to its libraries.=20
My configure.ac file of the project contains this lines:
#AC_PROG_F77([gfortran48 gfortran47 gfortran46 gfortran f77])
AC_PROG_F77
# Checks for header files.
#AC_HEADER_STDC
AC_CHECK_HEADERS([stdlib.h string.h])
#
LT_INIT([disable-shared])
#
AM_INIT_AUTOMAKE
#
AC_CONFIG_FILES([Makefile
src/Makefile
doc/Makefile
])
#
AC_OUTPUT
The command sequence to prepare the source is:
aclocal ; autoheader ; autoconf ; libtoolize -c ; automake -ac
And ./configure then dies with this:

Well, this looks pretty nice!
If the usage of the compiler is selected to be gfortran48 via
AC_PROG_F77([gfortran48 gfortran47 gfortran46 gfortran f77])
the I receive this crap:
checking for gfortran48... gfortran48

Checking config.log as suggested I find this portion:

This is funny - the FreeBSD port can not compile simple F77 code?
With gfortran47 using, I get this:
[...]
configure:2527: checking for suffix of executables
configure:2534: gfortran47 -o conftest conftest.f >&5
configure:2538: $? =3D 0
configure:2560: result:=20

configure:2588: $? =3D 0
configure:2595: ./conftest

fortran.so.3
not found configure:2599: $? =3D 1
configure:2606: error: in `/home/ohartmann/Projects/oepik':
configure:2610: error: cannot run Fortran 77 compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details
