Best alternative to the famous GCC ?

Xeratul · 05-11-2017, 02:36 PM

Hello,

I am looking for a possible more simple alternative to GCC?

Actually, I would be happy actually to have a small minimal source code of a C compiler for learning experience - learning in-depth C programming.

From Fabrice Bellard: https://fr.wikipedia.org/wiki/Fabrice_Bellard on his home page: https://bellard.org/ see TCC and OTCC.

he is really a king of programming, by excellence.

Code:

Tiny C Compiler (tcc), compilateur C, petit, mais complet ; à l'origine, il a été écrit pour gagner le concours humoristique « International Obfuscated C Code Contest » (concours du code le plus obscur en langage C).

clang/LLVM

https://clang.llvm.org

It has Apple behind it.

welcome - we have free mind - we use linux, bsd or the free unix family

Perhaps, but it's the only viable freeware alternative to gcc that I know of that will compile complex programs.

It has taken over gcc in Apple systems, gcc is just a link to it:

Code:

| =>  gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin16.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Did you try the Tiny C Compiler? Here is what Fabrice claims

Quote:

"TCC is a tiny but complete ISOC99 C compiler which enables you to use C as scripting language. TCC has its roots in the OTCC project. The TCCBOOT boot loader demonstrate the speed of TCC by compiling and launching a Linux kernel in less than 15 seconds."

Oh and about LLVM:

Code:

didier[/storage/slackware64-14.2/source/d/llvm/llvm-3.8.0.src]$ find -name "*.c"|wc -l
52
didier[/storage/slackware64-14.2/source/d/llvm/llvm-3.8.0.src]$ find -name "*.cpp"|wc -l
1649

So Xeratul, see you in a few years if you want to study all these source files thoroughly

PS Now to know how many lines of code you need to study:

Code:

didier[/storage/slackware64-14.2/source/d/llvm/llvm-3.8.0.src]$ find -name "*.cpp" -exec wc -l '{}' ';'| sed "s/ .*//" > /tmp/linescpp
didier[/storage/slackware64-14.2/source/d/llvm/llvm-3.8.0.src]$ for i in $(</tmp/linescpp);do nblines=$(($nblines + $i)); done; echo $nblines
4242656
didier[/storage/slackware64-14.2/source/d/llvm/llvm-3.8.0.src]$

Good luck.
