Intel Fortran Compiler can not be detected on linux

[PucklaJ]

Describe the bug

When I switch to the ifort toolchain using set_toolchains("ifort"), the compiler is not found. There is a workaround (see Additional Context) though it would be nice if it could be detected automatically. I installed the compiler from the official Intel website using the online installer.

Expected behavior

The Compiler and all related paths should be detected automatically by xmake.

Error output

Well, it just says toolchain("ifort"): not found!.

Related Environment

• ifort version: 2021.1.2
• xmake version: 2.5.9
• os: Garuda Linux
• target platform: Linux x86_64

Additional context

The workaround goes as follows:

1. Add the compiler executable to PATH
   For me I had to add ~/intel/oneapi/compiler/latest/linux/bin/intel64. Change intel64 to ia32 for x86.

export PATH="~/intel/oneapi/compiler/latest/linux/bin/intel64:$PATH"

2. Add the library folder to LD_LIBRARY_PATH
   For me I had to add ~/intel/oneapi/compiler/latest/linux/compiler/lib/intel64. Change intel64 to ia32 for x86.

export LD_LIBRARY_PATH="~/intel/oneapi/compiler/latest/linux/compiler/lib/intel64:$LD_LIBRARY_PATH"

This should be everything and now you can use ifort with xmake.

I have improved it but I have not environment to test it. You can try it. If it does not work, you can open a pr later. 0944d5a

Now it is able to find ifort, but when linking it can not find libimf.so. This file is inside the folder added to LD_LIBRARY_PATH, but it seems that the environment variable isn't actually accessed.

I have improved it on ifort branch, can you try it again.

xmake update -s github:xmake-io/xmake#ifort

https://github.com/xmake-io/xmake/pull/1898/files

But I have not tested it. if it dose not work, you can debug this patch and open pr to this branch.

I have improved to detect icc/ifort toolchains again on dev, you can try it.

xmake update -s dev

It's still the same libimf.so is not found. xmake does find ifort completely fine, but somehow LD_LIBRARY_PATH is not getting applied.
