[ncl-install] v 5.1.1 on x86_64 with PGI but g++ complains about unrecognized option '-pgf90libs', undefined references

[Marcin Sliwowski]

Hello Mary Haley and Fellow NCL Compilers,

Trying to compile NCL v. 5.1.1 on a 64 bit openSuse 11.1 system. The
system has the full suite of Portland Group Compilers, c/c++ and fortran
at v. 8.0-4. Have previously successfully compiled v. 5.0.0 andv.  5.1.0
with these compilers.

Current problem is a 2 part problem, not leaving out any details:

The log from 'make Everything' shows the following single error:

g++: unrecognized option '-pgf90libs'
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld:
cannot find -lhdfeos
collect2: ld returned 1 exit status
make[4]: *** [ncl] Error 1

Skipping over the first problematic issue that somehow g++ is involved
in the mix even though in $NCARG/config/ I have copied the file
LINUX.64.PGI over the file LINUX, so now the #define of CCompiler and
FCompiler are set to pgcc and pgf90 respectively. I must be doing
something wrong or forgetting to do something.

The other issue is that ld cannot file the library hdfeos. I have seen
this problem in both of the 2 previous versions of NCL that I have
compiled. To fix this problem I always have to do the following:

The Makefile in $NCARG/ni/src/ncl seems to mangle up its LIBSEARCH and
LIB_SEARCH paths somehow. In both of those variables the path to the
hdfeos libraries has the string 'linux' replaced with the string '1'.
For example in my case it should be
-L/usr/local/hdfeos-2.14.v1/lib/linux but instead in both of the
variables in the Makefile it is -L/usr/local/hdfeos-2.14.v1/lib/1. I
don't know why the string 'linux' is replaced with the string '1', maybe
it has something to do with the fact that I installed hdfeos under
/usr/local/hdfeos-2.14.v1 instead of the default /usr/local. Does anyone
know why this replacement occurs?

There is another instance of the string 'linux' being replaced with the
string '1'. In the INC_SEARCH and INCSEARCH variables in the same
Makefile -I/usr/include/linux is replaced with -I/usr/include/1 which
leads to the following error during a subsequent make depend in the
current directory:

cannot find include file "stddef.h" not in /usr/include/stddef.h
cannot find include file "limits.h"

I edit the Makefile replace the instances of '1' with 'linux' and then
in that same directory I issue the commands: make includes, make depend
and make all.

On the "make all" is where I run into the serious trouble that I need
help with. I get a whole slew of errors regarding undefined references,
but before them I get the line: g++: unrecognized option '-pgf90libs'.
Here are the undefined reference errors:

dspmv.f:(.data+0x18): undefined reference to `pgf90_compiled'
undefined reference to `pgf90io_encode_fmt'
undefined reference to `pgf90io_fmt_write'
undefined reference to `__c_mset8'

At this point I comment out the current definition of the variable
CTOFLIBS and insert the following in the Makefile:
#CTOFLIBS       = -pgf90libs
CTOFLIBS        = -pgf90libs -lpgc -lpgf90  -lpgf90_rpm1  -lpgf902
-lpgftnrtl -lpghpf

After this change the make all still states: g++: unrecognized option
'-pgf90libs' and the number of undefined references drops significantly
but the following kind still remain:

/opt/pgi-8.04/linux86-64/8.0-4/lib/libpgf90.a(ftnexit.o): In function
`f90io_pause':
ftnexit.c:(.text+0x13e): undefined reference to `_mp_bcs_stdio'
ftnexit.c:(.text+0x1d1): undefined reference to `_mp_ecs_stdio'
/opt/pgi-8.04/linux86-64/8.0-4/lib/libpgftnrtl.a(ftncharsup.o): In
function `ftn_str_copy':
/usr/pgrel/extract/x86/8.0/rte/pgftn/hammer/lib-linux86-64/../../port/support/src/ftncharsup.c:83:
undefined reference to `_mp_malloc'
/usr/pgrel/extract/x86/8.0/rte/pgftn/hammer/lib-linux86-64/../../port/support/src/ftncharsup.c:106:
undefined reference to `_mp_malloc'
/usr/pgrel/extract/x86/8.0/rte/pgftn/hammer/lib-linux86-64/../../port/support/src/ftncharsup.c:147:

/usr/pgrel/extract/x86/8.0/rte/pgftn/hammer/lib-linux86-64/../../port/support/src/ftncharsup.c:159:
undefined reference to `_mp_free'

I am guessing that because g++ somehow gets involved it is not able to
find the libraries that the PGI compilers come with that I am guessing
would provided these methods that are currently undefined. In my
environment I have the following variables exported:

export CC=pgcc
export CXX=pgCC
export FC=pgf95
export F77=pgf77
export
LD_LIBRARY_PATH=${PORTLAND_COMPILERS}/libso:${PORTLAND_COMPILERS}/lib:${LD_LIBRARY_PATH}
export
LIBRARY_PATH=${PORTLAND_COMPILERS}/lib:${PORTLAND_COMPILERS}/libso:${LIBRARY_PATH}

Any help would be greatly appreciated.

Thank You,
Marcin
