Passing options for a specific compiler to fpm

Help
1

I have been experimenting with the FMZM library by David Smith for multiple-precision calculations with the intent to make it accessible via fpm. But for the Intel ifx compiler I need a specific compile option. Is it possible to do so? That is: can you specify in the toml file that option A is to be added if you use compiler B?

Unless that changed, I think you cannot. However, you can use response file. I usually have a fpm.rsp sitting next to the fpm.toml which looks like this

@clean
option clean --all

@rebuild
system rmdir /s /q build
option build --flag '-ffree-line-length-none'

@build
option build --flag '-ffree-line-length-none'

so you could define:

@build-intel
option --flag '  '

@build-gfortran
option --flag '  '

PS: if you do this in Powershell, the @ symbol is reserved so you have to do fpm --% @build-intel. The --% deactivates ‘smart’ parsing.

Not yet, but likely in the next release, as it is being discussed

Okay, thanks for this! I guess a response file is the way to go then for the moment.
