What if someone doesn't use `gcc`? #12

Closed ghost closed 1 year ago

ghost commented 1 year ago

I want to use Pelles C to build my code. How could I specify the compiler? It seems gcc is assumed and only gcc is supported.

p/s: I want to build my code with Pelles C. I don't want to build BUSY itself with Pelles C. Let's make it clear.

BUSY currently supports GCC, CLANG and MSVC; CLANG support on Windows is restricted.

I never heard of Pelles C so far, but if it has a way to look compatible to MSVC or GCC then it might work with BUSY.

CLANG support on Windows is restricted.

Could you elaborate more?

There is an unofficial project on Github that provides wrapper for Pelles C to make it look like GCC:

The problem is the binary name is not gcc. With other build systems I could specify CC=pellescc AR=pellesar on the command line or even have a way to set that in the build script. So far, I don't see any way to do this with BUSY.

From https://github.com/rochus-keller/leancreator/: "Clang on Windows seems to work, but there are tons of compiler errors when compiling LeanQt. "

The problem is the binary name is not gcc.

Not really a problem; just make an alias or copy and call it gcc. You can also use the "target_toolchain_prefix" predeclared variable of BUSY (see manual).

Btw, the Pelles C's GCC wrapper is too limited. I want to use Pelles C directly. CMake offers a way for me to extend it to add unsupported compilers. How could I add an unsupported compiler to BUSY?

rochus-keller commented 1 year ago

There is no such feature (yet) in BUSY.

What is that much better in Pelles C than CLANG or GCC that you want to use it?

Pelles C has excellent document and I'm already familiar with the toolchain.

rochus-keller commented 1 year ago

Ok, I see. Unfortunately I cannot support other toolchains for the moment, so I recommend that you continue with Cmake for now.
