IOAPI 3.2 installtion error: undefined reference to `curl_easy_strerror'

[Iqbal]

Hello,

I am trying to install IOAPI3.2 using netcdf4.7.4 and pgi compiler. I have successfully installed ioapi which creates libioapi.a. Attached is Makeinclude file Makeinclude.Linux2_x86_64pg.txt (2.0 KB) where you can see i used

FOPTFLAGS = -O2 -V -Mnosecond_underscore
FPPFLAGS = -DF90=1
FSFLAGS = -Msave
ARCHFLAGS = -DFLDMN=1 -DAUTO_ARRAYS=1 -DF90=1 -DNDEBUG -DIOAPI_NCF4=1

But by using same settings when I tried install ‘m3tools’, I get the following error Makefile.txt (13.0 KB) :

[IqbalHossan@adeq m3tools]$ make

[cjcoats]

Where did you get your netCDF libraries? And why did you not follow the I/O API Build Instructions? https://cjcoats.github.io/ioapi/AVAIL.html#build

Acquire and build the netCDF library, libnetcdf.a (and libnetcdff.a for netCDF-4.1 or later), for each configuration. …See NOTES on netCDF-4 for configuring netCDF-4.

and https://cjcoats.github.io/ioapi/AVAIL.html#ncf4

NetCDF Version 4.x have lots of additional build options, that will require a complex set of additional libraries in your Makefiles and all other model-building systems. It is recommended that you disable these options by adding the command-line flags below to your netCDF configure command:

–disable-netcdf4 --disable-dap

…If you don’t build netCDF as indicated above, you will need additional libraries that may be discovered by running the netCDF commands

nc-config --libs
nf-config --libs

[Iqbal]

Hello @cjcoats,

Thank you for your response. since I did not add
–disable-netcdf4 --disable-dap in my NetCDF building, I added [[[ according to Availability/Download of the BAMS/Models-3 I/O API If you build netCDF-4 without the --disable-netcdf4 , you will also need to add -DIOAPI_NCF4=1 either to the ARCHFLAGS in your Makeinclude.${BIN} or to the DEFINEFLAGS in your Makefile ]]]

-DIOAPI_NCF4=1 to the ARCHFLAGS in the Makeinclude.Linux2_x86_64pg file.

I am not sure If I understand the above mention line regarding DIOAPI_NCF4=1 option.

I greatly appreciate your help. Thanks in advance

[cjcoats]

netCDF4-with-HDF has INTEGER*8 operations; without HDF, it does not. -DIOAPI_NCF4=1 handles that situation – the I/O API needs to be able to work (i.e., compile and link) both with and without the INTEGER*8 ops…

[Iqbal]

Okay, One more question:

From the link: Availability/Download of the BAMS/Models-3 I/O API
It says " If you don’t build netCDF as indicated above, you will need additional libraries that may be discovered by running the netCDF commands

nc-config --libs
nf-config --libs 

"

My nc-config --libs and nf-config --libs are below:

[IqbalHossan@adeq soft]$ nc-config --libs
-L/usr/local/netcdf-4.7.4/lib -lnetcdf

[IqbalHossan@adeq soft]$ nf-config --libs
unknown option: --libs
Usage: nf-config [OPTION]

Available values for OPTION include:

–help display this help message and exit
–all display all options
–cc C compiler
–fc Fortran compiler
–cflags pre-processor and compiler flags
–fflags flags needed to compile a Fortran program
–has-dap whether OPeNDAP is enabled in this build
–has-nc2 whether NetCDF-2 API is enabled
–has-nc4 whether NetCDF-4/HDF-5 is enabled in this build
–has-f90 whether Fortran 90 API is enabled in this build
–has-f03 whether Fortran 2003 API is enabled in this build
–flibs libraries needed to link a Fortran program
–prefix Install prefix
–includedir Include directory
–version Library version

For the nf-config --libs, it is giving me ‘unknown option’ error. What does that mean?

Thank you

[Iqbal]

So, as your suggestion I have tried to built netcdf4.7.4 with --disable-dap option

./configure --disable-netcdf4 --disable-dap --prefix=/home/IqbalHossan/Documents/soft/netcdf-4.7.4

After that, the built was successful but when I do
nf-config --libs

It’s giving me same error as mentioned in previous comment

Then I tried to build IOAPI 3.2 , I was able to compile ioapi but when I try to compile m3tools, I get this error:

Please help

[cjcoats]

OK, it looks like they’ve changed the --libs to --flibs. Don’t you love software-compatibility? ;-(

[Iqbal]

Okay,
Here is the output

But when I tried to use this libnetcdf.a libnetcdff.a in the IOAPI3.2 for m3tools compilation, (makefile for the m3tools Makefile.txt (13.0 KB)
I get the following errors:

Would you please help me with that?
Thanks

[cjcoats]

Your libnetcdff.a seems to have nf_put_vara_int64_, so you do not need the “dummy” placeholder-definition of that routine in MODULE MODNCFIO.

Add -DIOAPI_NCF4=1 to the compile flags, then make clean; make for the I/O API so that the dummy placeholder will not be enabled…

[Iqbal]

Thank you so much @cjcoats , it works
