Unknown intel compiler version (error: _AX_COMPILER_VERSION_INTEL) #7

Closed ben-ljmu closed 5 years ago

ben-ljmu commented 5 years ago

Hi,

We're having difficulty compiling the code on Ubuntu 18.04.1 using ICC version 18.0.1. After running ./autogen, using ./configure CC=icc MPICC=mpicc exits with the following error:

checking for C compiler version... configure: error: in `/path/to/files':
configure: error: _AX_COMPILER_VERSION_INTEL unknown intel compiler version

However, using the exact same compiler on Ubuntu 16.04.5 seems to work fine.

Hardcoding the version number using ax_cv_c_compiler_version="18.0.1" lets the configure step complete successfully (although CFLAGS have to be set manually).

Thanks!

We've not seen that one before. Odd that it changes between Ubuntus. Can you attach the files config.log and configure from a failed attempt?

ben-ljmu commented 5 years ago

It does seem strange. I've attached both files from a failed attempt below. Thanks again!

config.log configure.txt

Thanks, so the problem is new support for the types _Float32 _Float64 and others see:

The fix looks scheduled for the 2019 releases, maybe. In the meanwhile the only work around is to define these missing types in your CFLAGS:

 ./configure CFLAGS="-D_Float32=float -D_Float32x=float -D_Float64='long double' -D_Float64x='long double'"

I'm guessing. You may need to work on the quotes.

Is this problem fixed now?

ben-ljmu commented 5 years ago

Yep, there's no error when using the 2019 Intel compiler. Thanks
