I get the same error trying to build fpm from a clean copy of the repo:

It looks like this is connected to previous issues:

• Might know why fpm does not compile with ifort #324
• building fpm with ifort #520

As @urbanjost suggested there, importing toml_table directly from tomlf makes the issue dissappear:

! BEFORE
  use fpm_toml, only : toml_table, toml_key, toml_stat, get_value, set_value, serializable_t

! FIXED
  use tomlf, only: toml_table
  use fpm_toml, only: toml_key, toml_stat, get_value, set_value, serializable_t

Was there ever a better explanation of why ifort can't re-export the toml_table type?

Could it be that one of the generic procedures added in fpm/src/fpm/toml.f90 (module fpm_toml)

fpm/src/fpm/toml.f90

Lines 59 to 81 in da6d1bf

	!> add_table: fpm interface
	interface add_table
	module procedure add_table_fpm
	end interface add_table
	!> set_value: fpm interface
	interface set_value
	module procedure set_logical
	module procedure set_integer
	module procedure set_integer_64
	end interface set_value
	interface set_string
	module procedure set_character
	module procedure set_string_type
	end interface set_string
	!> get_value: fpm interface
	interface get_value
	module procedure get_logical
	module procedure get_integer
	module procedure get_integer_64
	end interface get_value

has an equal interface to one of the existing procedures add_table, set_value, get_value procedures, that are part of the original toml-f library?

Edit: Nvm, I think that cannot be the case, because the procedures in fpm_toml have an additional error_t dummy argument, so their interfaces should be distinguishable. Also the compiler error in this case would be this one:

/app/example.f90(34): error #5286: Ambiguous generic interface BAR: previously declared specific procedure A::FOOBAR is not distinguishable from this declaration. [BFOOBAR]
subroutine bfoobar(f)

[awvwgk]

I am surprised that this issue is limited to reexporting the table type and does not affect for example the key type, notably the tomlf module already provides a reexported table type. Overall this looks like a bug in the Intel compiler, so maybe worth reporting in the Intel community forum.

[ivan-pi]

Intel deprecated ifort meaning that Mac users with Intel processors are stuck with the old versions of ifort. I will check if the bug disappears with a 2024 version of ifx on my Ubuntu machine.

I managed to get a working build with use tomlf, only: toml_table everywhere it was needed (between 10-15 places in the fpm source).

This issue has been discussed several times, and Intel has reported to be working on a fix:

[ivan-pi]

Thanks for pointing the thread out. Even if Intel provides a fix for ifx, it won't help me because of the Deprecation of Intel Fortran Compiler Classic on MacOS. It's a pity because this also means fpm can't be used as a dependency:
