With set_toolchains("@cosmocc") : fatal error: string: No such file or directory

[raphael10-collab]

With this xmake.lua file :

set_languages("c99", "c++20")
add_rules("mode.debug", "mode.release")

add_requires("cosmocc")

target("isdigits")
    set_kind("binary")
    add_files("/home/raphy/isdigits/src/*.cpp")
    --set_toolchains("@cosmocc")

It works fine :

raphy@raohy:~$ xmake f -o /home/raphy/isdigits/builddir

raphy@raohy:~$ xmake
[ 50%]: cache compiling.release isdigits/src/isdigits.cpp
[ 75%]: linking.release isdigits
[100%]: build ok, spent 0,482s

raphy@raohy:~$ ./isdigits/builddir/linux/x86_64/release/isdigits 
Only digits

Alpha Numerical

If I activate this line : set_toolchains("@cosmocc") :

set_languages("c99", "c++20")
add_rules("mode.debug", "mode.release")

add_requires("cosmocc")

target("isdigits")
    set_kind("binary")
    add_files("/home/raphy/isdigits/src/*.cpp")
    set_toolchains("@cosmocc")

I get that error :

raphy@raohy:~$ xmake

This is an issue with cosmocc, I'm not sure if it supports stl and can find it automatically. xmake doesn't need to do anything else.
