[gdal-dev] cmake status update - 99% good news!

[Joaquim Manuel Freire Luís]

Don’t know which commit did it. Updated this afternoon and started to erroring right away with missing 'ws2_32.lib`

I do have HDF4 but before I was able to build till the end. I've here a gdal_w64.dll smiling to me. That's why I said it got worst.
Sorry you lost me. Is https://github.com/OSGeo/gdal/pull/5179 helping or not ?  If not helping, which commit in it is causing an issue ?

ninja: error: 'ws2_32.lib', needed by 'gdal_w64.dll', missing and no known rule to make it



I'd say on the contrary that it helped the build to go further, didn't it ? My fixes are totally unrelated to a ws2_32.lib missing



I see in configure.ac that we had the following logic



dnl

---------------------------------------------------------------------------

dnl Check if we need -lws2_32 (mingw)

dnl

---------------------------------------------------------------------------



echo "#include <winsock2.h>" > test_ws2_32.c echo "#include <ws2tcpip.h>" >> test_ws2_32.c echo "void foo() {}" >> test_ws2_32.c



if test -z "`${CC} -c test_ws2_32.c 2>&1`" ; then

  LIBS="$LIBS -lws2_32"

fi

rm -f test_ws2_32*



dnl

---------------------------------------------------------------------------

dnl Check if we need -lpsapi (mingw)

dnl

---------------------------------------------------------------------------



echo "#include <windows.h>" > test_psapi.c echo "#include <psapi.h>" >> test_psapi.c echo "void foo() {}" >> test_psapi.c



if test -z "`${CC} -c test_psapi.c 2>&1`" ; then

  LIBS="$LIBS -lpsapi"

fi

rm -f test_psapi*



This hasn't been ported yet to cmake builds.



I've ticketed that in https://github.com/OSGeo/gdal/issues/5180.



Hum, upon reflection, the error message would seem to indicate that we try to link to ws2_32.lib but it is not found in your environemnt



Looking for ws2_32 in cmake build scripts, I see it is referenced in



cmake/modules/packages/FindODBC.cmake: set(_odbc_required_libs_names

odbccp32;ws2_32)

cmake/modules/packages/FindHDF4.cmake:        list(APPEND HDF4_LIBRARIES

ws2_32.lib)



Do you use any of ODBC or HDF4 in your build ? Could you try to disable them and see if it makes a difference ?



Or maybe if you've HDF4, try to change the ws2_32.lib to ws2_32 in cmake/modules/packages/FindHDF4.cmake ?
