Hello everyone,
I'm writing to you because I want to use METplus to evaluate the output of the WRF model. However, I'm having trouble installing the software. I've looked through the old discussions but have not been successful. I'm getting errors. I've attached the various log files.
I've also attached the last lines from my terminal.
Thank you in advance for your help

[JohnHalleyGotway]

@koupel, thanks for letting us know about the compilation issue and for sending your met.make.log file.

Can you please let me know the organization or institution with which you're affiliated, so I can add a "requestor" label to this discussion to help us keep track of the support we provide?

On to the issue at hand. Here's the relevant error from the met.make.log file:

temp_file.cc: In function ‘void remove_temp_file(ConcatString)’:
temp_file.cc:68:8: error: local external declaration ‘int* __errno_location()’ [-fpermissive]
   68 |    int errno;
      |        ^~~~~
/usr/include/errno.h:37:13: note: does not match previous declaration ‘int* __errno_location()’
   37 | extern int *__errno_location (void) __THROW __attribute_const__;
      |             ^~~~~~~~~~~~~~~~

Doing some investigating, I see that we reference the errno variable in several spots in MET without actually declaring them as local variables, as is being done with int errno; on line number 68 of temp_file.cc. The other spots are fine because errno must be defined in the errno.h header file, and so include <errno.h> is all that's needed.

I do note that that int errno; line has been present in temp_file.cc for 14 years and has never caused a problem previously.

Looking in config.log I see that you're compiling with GNU g++ 9.4.0:

g++ (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0
Copyright (C) 2019 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

So I'm a bit puzzled as to why this is being flagged. For reference, we're currently using GNU 12.2.0 in our development environment:

g++ (Debian 12.2.0-14) 12.2.0
Copyright (C) 2022 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The good news is that I think this is very easy to fix. Please try modifying src/basic/vx_config/temp_file.cc by either deleting or commenting out (i.e. //int errno;) line number 68 from that file, and then try recompiling. Since you've already run configure, you can just run make clean install from the top-level MET directory.

I tested with the same change in our development environment and note that it compiles fine without that local variable being set. Does that get past this error message?

Another option is compiling with a more recent compiler version... but 9.4.0 from 2019 is not all that old. So I'd fully expect that we should be able to compile MET with it.

Please let me know how it goes. If removing that line fixes it, we could either pull back the 12.0.2 bugfix release and reissue it, or just include that change in the next official MET version 12.1.0.

Hello @JohnHalleyGotway , thank you for your reply. I'm currently attached to CNR-IBE but I'm looking to install the software on my personal machine.
I took into account your remark, the compilation worked but I meet another problem. Thank you

@koupel, I see you're encountering linker errors when compiling MET, specifically with NetCDF's dependence on curl. Unfortunately, the fix for this is not as easy or obvious as the last one and indicates more of an issue with the configuration of your environment than an issue in the MET codebase itself.

I'll note that the ensemble_stat tool is the first application that's compiled... after all the library code is compiled. And so linker errors usually show up there since it's the first time linking is performed. So there's nothing specific about ensemble_stat causing this problem.

Our METplus team consists of scientists, statisticians, and software engineers... but not systems administrators. To solve your environment issue, we'd be doing the same thing I'm sure you've already done - googling the linker error and looking for solutions. Perhaps it'd be solved by installing or updating the system libcurl4 library, but I really don't have much beyond that to offer.

@jprestop have you seen libcurl linker errors before and have any other suggestions?

I will note two alternatives...

1. Pre-compiled versions of MET and METplus are provided through DockerHub. Of course this requires having Docker Desktop installed on your machine. And running software through Docker has its own learning curve (like how to map local directories into the container and how to get output from it)... but running a MET tool is literally a one-liner. For example, this command automatically pulls the MET 12.0.2 build from DockerHub and prints the grid_stat usage statement:

docker run -it --rm dtcenter/met:12.0.2 grid_stat -help

2. @georgemccabe is working on a Conda build for METplus as described in Enhancement: Install METplus via Conda #2863. He is making good progress but is not finished yet. Once the build is working well, he'll push it up to conda-forge. And compiling MET/installing METplus through Conda would likely be easier than compiling locally. If you're interested in the Conda route, I'm guessing @georgemccabe would appreciate friendly beta testers.

Hi @koupel.

@jprestop have you seen libcurl linker errors before and have any other suggestions?

Yes. You could try installing the curl library yourself and pointing to the location of the library and include files. You would run the following:

cd /home/thomas/Software/METplus/12.0.2/external_libs/
mkdir curl
cd curl
wget https://curl.se/download/curl-8.1.0.tar.gz
tar -zxf curl-8.1.0.tar.gz
cd curl-8.1.0
./configure --prefix=/home/thomas/Software/METplus/12.0.2/external_libs/ --without-ssl
make install > & make_install.curl.log

Then, please set up the environment again, by running the following:

export MET_PYTHON_CC=-I/home/thomas/anaconda3/include/python3.12
export MET_NETCDF=/home/thomas/Software/METplus/12.0.2/external_libs

Then, rerun:

make clean install

If you'd like to use one of the other suggestions that @JohnHalleyGotway that is fine as well. Please let us know how it goes.
