Hi,
I'm trying to build NETCDF on (a QEMU emulation of) a RISC-V platform we're
developing.
I've successfully built other libraries (like HDF5, zlib, etc.) on this QEMU
with gcc 14.2.0.
However, I am having difficulty completing the configuration phase of the
NETCDF build process.
This machine will not be accessing the web or pulling down anything, so I
disabled DAP and XML, and am not giving it curl.
I started with this configure command:
./configure --disable-dap --disable-libxml2 CPPFLAGS="-I/home/root/WRF/include"
LDFLAGS="-L/home/root/WRF/lib" 2>&1 | tee configure-net.out
But I get errors like:
checking size of size_t... configure: error: in
'/home/root/repos/netcdf-c-4.9.3':
configure: error: cannot compute sizeof (size_t)
See 'config.log' for more details
I reasoned that the configure script might be confused about the host or built
targets, so I decided to be explicit.
Below is the latest attempt. I added the cache file:
root@qemuriscv64:~/repos/netcdf-c-4.9.3# cat config.cache
ac_cv_sizeof_off_t=8
And then I ran:
./configure --disable-dap --disable-libxml2 CPPFLAGS="-I/home/root/WRF/include"
LDFLAGS="-L/home/root/WRF/lib" --host=riscv64-linux-gnu
--build=riscv64-linux-gnu --cache-file=config.cache 2>&1 | tee
configure-net.out
It fails with the same error.
This error is detected in line 26715 of the configure script.
I see from the comments that this test serves to guard against an error in the
HP compiler. Is this still a useful test?
I would suspect our toolchain usually, but it's built hdf5 and multiple other
applications.
Thanks in advance,
