Could not compile conftest.f, error: identifier "choke" is undefined

[wannh2]

I'm trying to install netcdf-fortran 4.6.1, but met the error "Could not compile conftest.f", after find the config.log, I found "error: identifier "choke" is undefined", here is the command I use for netcdf-fortran
export CC=pgcc
export FC=pgfortran
export CXX=c++

LD_LIBRARY_PATH=/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/lib:$LD_LIBRARY_PATH
CPPFLAGS=-I/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/include
LDFLAGS=-L/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/netcdf/lib
./configure --disable-shared --prefix=/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/

for netcdf-c, the command is:
CPPFLAGS=-I/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/hdf5/include
LDFLAGS=-L/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/hdf5/lib
./configure --prefix=/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/ --disable-dap --disable-shared

system inf:
Ubuntu 18.04.6 LTS (GNU/Linux 4.15.0-197-generic x86_64)
zlib 1.2.11
hdf5 1.15.4-3
netcdf-c 4.9.2

any suggestion for this error? Thank you in advance

config.log

If you look at line 719 of your config.log, you will see the problem:

configure:22655: pgfortran -c -fopenmp -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -ffunction-sections -pipe -isystem /home/nenghan/miniconda3/include conftest.f
pgfortran-Error-Switch -tp with unknown keyword nocona
configure:22658: $? = 1

Where are all these extra CFLAGS coming from? You do not list them in your set of environment variables...

Thanks, I don't set the enviroment CFLAGS as "/home/nenghan/miniconda3/include", this is another netcdf, like a default one, so when I run "nc-config --all", it comes

for this netcdf-fortran 4.6.1, I first install netcdf-c 4.9.2 in "/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/", then I set enviroment：
LD_LIBRARY_PATH=/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/lib:$LD_LIBRARY_PATH
CPPFLAGS=-I/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/include
LDFLAGS=-L/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/netcdf/lib
./configure --disable-shared --prefix=/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/

and get the error mention above, any suggustions?

here is the inf when I run "/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/bin/nc-config --all"

OK, this is a little hard to follow.

Did you successfully install netcdf-c-4.9.2? Did you run make check and all tests passed?

The problem you started with was a failure of your fortran compiler to work, due to some of the flags that are set. You have to figure out what that's all about so your fortran compiler works. Look in config.log to find where it failed and start from there.

thank you, I have installed netced-c 4.9.2, and make check and make install passed

Looking at this, I see the following:

ac_cv_env_FFLAGS_value='-fopenmp -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -ffunction-sections -pipe -isystem /home/nenghan/miniconda3/include'

What do you see if you run env | grep FFLAGS from your terminal? I believe the issue may be solved if you remove -march=nocona from your FFLAGS, but the first step will be to figure out where they are being set in the first place.

[wannh2]

Thank you, the 'env | grep FFLAGS' returns:

FFLAGS=-fopenmp -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -ffunction-sections -pipe -isystem /home/nenghan/miniconda3/include -fopenmp -march=nocona -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-all -fno-plt -Og -g -Wall -Wextra -fcheck=all -fbacktrace -fimplicit-none -fvar-tracking-assignments -ffunction-sections -pipe

I remove ' -march=nocona' doesn't work, but I find FFLAGS points to my system default netcdf library path, here I install my netcdf in '/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/include', so I set FFLAGS=-I/mnt/work/wannh/build_megan/library/netcdf_pg/Build_WRF/LIBRARIES/netcdf/include, and the problem is solved
