Visual Studio issues in `main` development branch

[WardF]

Failures observed under Windows using main; these failures are new compared to the v4.9.2 release. The following tests are failing on Windows 10 under Visual Studio 2017.

• ncdap_tst_ncdap3
• dap4_test_test_raw
• nczarr_test_run_interop
• nczarr_test_run_quantize

Failures need to be explored. Output from the failing tests are in the attached file. Does anything immediately leap out at you, @DennisHeimbigner ? I'm still getting a dev environment on Windows 11 with Visual Studio 2022 stood up; I'm seeing weird issues trying to link against libcurl.

Can you post the CMake options you used?

[WardF]

Hi Dennis,

The only options I'm using are

$ cmake .. -DCMAKE_PREFIX_PATH=[path to my local development libraries]

Other than that, default values are used.

Ward- I am building with Visual Studio 2019 community edition. I use the sequence of commands below the dotted line. I should note that I am working in a cygwin environment.

Everything builds and tests ok, including the tests that fail for you, namely:

• ncdap_tst_ncdap3
• dap4_test_test_raw
• nczarr_test_run_interop
• nczarr_test_run_quantize

The CMAKE_IMPORT_LIBRARY option points to where I have built the various support libraries. Note the use of the CURL_NO_CURL_CMAKE option; may be relevant.

NCPWD=`pwd`
NCCYGLIB=$NCPWD/build/liblib
NCCLIB=/cygdrive/c/tools/hdf5-1.10.6/lib
NCCBIN=/cygdrive/c/tools/hdf5-1.10.6/bin
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${NCCYGLIB}:${NCCLIB}:${NCCBIN}"
export PATH="${NCCBIN}:$PATH:$NCCYGLIB:${LD_LIBRARY_PATH}"

rm -fr build
mkdir build
cd build

cmake -DBUILD_SHARED_LIBS=ON -DNC_FIND_SHARED_LIBS=ON -DCMAKE_IMPORT_LIBRARY_PREFIX=c:/tools/hdf5-1.10.6 -DCMAKE_INSTALL_PREFIX=d:/tmp/netcdf -DHDF5_DIR=c:/tools/hdf5-1.10.6/cmake/hdf5 -DCURL_NO_CURL_CMAKE=ON ..
cmake --build . --config Release --target ALL_BUILD
cmake --build . --config Release --target RUN_TESTS

@DennisHeimbigner That is encouraging; I'm using MSYS bash and will test with a CMD command line. I wonder if it is a pathing issue. I'll also install Cygwin and see what results I observe.
