Compiling errors relating to copygb.F

[wyhqq]

In the installation of hpc-stack-DTC(with ./build_stack.sh -p /app/hpc-stacks -c config/config_comgsi.sh ), only the grib-util software is not installed successfully in hpc-stack-DTC:

the errors are as follows:

BUILD FAIL! Lib: grib_util Error:2

How should i resolve the problem?

[kgerheiser]

The references to ipolates means the ip library is not being linked properly.

Where are you building and compiler are using? Could you show the link line right before the errors and maybe the line where CMake finds ip at the beginning of the build? This library is built frequently without issue.

[wyhqq]

Dear kgerheiser,

I compile it with gcc-9.1.0 on a supercomputer.

The ip library link seems to be OK.

The compile command line :
/gcc-9.1.0/bin/gfortran -g -fdefault-real-8 -O3 CMakeFiles/copygb.dir/copygb.F.o -o copygb /app/hpc-stacks/lib/libbacio_4.a /app/hpc-stacks/lib/libw3nco_4.a /app/hpc-stacks/lib64/libip_4.a /app/hpc-stacks/lib64/libsp_4.a /app/gcc-9.1.0/lib64/libgomp.so -lpthread

By the way, the /app/hpc-stacks/lib64/libip_4.a is compiled successfullly.

Is there any other possibility for the compiling errors?

[kgerheiser]

Yeah, that looks right. It's the same link line I get with a successful build, but something is definitely being linked wrong if it can't find ipolates, ipolatev or makgds, which come from libip.

By any chance are you using the develop branch of ip? There's been some changes in there that would break grib_util in a suspiciously similar way.

[wyhqq]

There are several branches in https://github.com/NOAA-EMC/NCEPLIBS-grib_util,

Do you mean I should download NCEPLIBS-grib_util-master.zip other than NCEPLIBS-grib_util-develop.zip ?

[kgerheiser]

No, I mean are you using the develop branch of NCEPLIBS-ip somehow?

https://github.com/NOAA-EMC/NCEPLIBS-ip

There are some compatibility breaking changes in the develop branch.

[wyhqq]

Thanks a lot. I will download master branch zip files, compile it again and response the results to you.

[kgerheiser]

I recommend using the most recent release, tag v3.3.3

[wyhqq]

The build-stacks.sh download the IP with the following command：
git clone https://github.com/noaa-emc/nceplibs-ip ip-v3.3.3
But it is not clear which version will be downaded ( the NCEPLIBS-ip-develop.zip or the NCEPLIBS-ip-master.zip).

[wyhqq]

I found the tag v3.3.3, thanks

[wyhqq]

The same errors still comes up when I compile the grib-util even if I download the nceplibs-ip with tags v3.3.3 and compile it again.

[kgerheiser]

I really think that's what the problem was. Did you install the new version and make sure remnants of the old build were deleted?

You can run nm libip_4.a to see the symbols in the library, and in there you should see makgds, ipolates, and ipolatev.

[edwardhartnett]

Is this still an issue?

NCEPLIBS-grib_util is building well on my development machine and the github CI systems...
