We are trying to install hdf5 (version: 1.14.3) with latest intel compilers (ICX, ICPX, and IFX) by **./configure --prefix=/apps/wrf\_lib --enable-shared --with-pic CFLAGS=“-fPIC -O3 -xHost -ip -fno-alias -align” FFLAGS=“-fPIC -O3 -xHost -ip -fno-alias -align” CXXFLAGS=“-fPIC -O3 -xHost -ip -fno-alias -align” FFLAGS=“-I/opt/intel/oneapi/compiler/2024.0/include -L/opt/intel/oneapi/compiler/2024.0/lib”** as per previous suggestions. But we got errors like below (We are trying to attach the log file but that option (upload) is not supporting for the new users) : ```auto checking for gcc... icx checking whether the C compiler works... no configure: error: in `/home/wrf_build/source_files/hdf5-1.14.3': configure: error: C compiler cannot create executable See `config.log' for more details ``` But, I have all the intel compilers which icx /opt/intel/oneapi/compiler/2024.0/bin/icx which ifx /opt/intel/oneapi/compiler/2024.0/bin/ifx which icpx /opt/intel/oneapi/compiler/2024.0/bin/icpx ```auto **Please provide the solutions/suggestions to overcome from this problem.** Thank you, Srinivas ``` ---

Hi, Would you please share `config.log`? In the mean time, please check if CXX is defined as shown below: [hdf5/.github/workflows/intel-auto.yml at develop · HDFGroup/hdf5](https://github.com/HDFGroup/hdf5/blob/develop/.github/workflows/intel-auto.yml#L40C11-L40C14) You can also try `./configure CXX=/full/path/to/icpx ...`. Second, try disabling fortran `--disable-fortran`. That’s our CI does now as you can see from the above link. Finally, remove all FLAGS to match our CI: `./confgiure --enable-shared --disable-fortran` ---

Dear Sir, Based on your suggestions, we followed these steps: ``` 1. Exported the paths of CC (icx), CXX (icpx), and FC (ifx). 2. Disabled Fortran (--enable-shared --disable-fortran). 3. Did not import the flags (FFLAGS, CFLAGS, FFLAGS, CXXFLAGS). ``` Interestingly, **it now appears to be working fine**. Please review the log file and provide any further suggestions or corrections. Thank you. Srinivas [logfile.tar.gz](https://forum.hdfgroup.org/uploads/short-url/8clFbhMGmSSZzwQzhsSZkYkZFam.gz) (33.7 KB) ---

My experience is that the CMake builds have been working a lot better with the new Intel compilers than the autotools (configure). I have used CMake + icx/ifx for HDF5 for a long time without problems. ---

@yernisrinivasnekkali , you may want to try _ **1.14.4** _ snapshot: ```auto curl -O -L https://github.com/HDFGroup/hdf5/archive/refs/tags/snapshot-1.14.tar.gz tar zxf snapshot-1.14.tar.gz cd hdf5-snapshot-1.14 ./configure --prefix=/tmp CC="$(which icx)" FC="$(which ifx)" --enable-build-mode=production --enable-fortran make -j make check -j ``` I tested it yesterday and `--enable-fortran` worked fine with _ **2024.1** _ Intel oneAPI. ---

Dear Sir, The provided HDF5 file was installed successfully with Fortran enabled (–enable-shared and --enable-Fortran). It’s important to note that we didn’t import any flags (FFLAGS, CFLAGS, and CXXFLAGS). Please review the log file and provide any further suggestions or corrections.
