   You know @ekaitz_zarraga?

   I'm trying #TinyCC! 😉

   I gave a look to all the compilers at http://suckless.org/rocks/ but apparently #tcc is the most mature and the only one completelly self-sufficient.

   BUT.

   I do not know.

   What it I restart from #9front?No ELF. No #POSIX. No... shit.

   It took a huge amount of work to do all this in #Jehanne but... why going after so much complexity? Why not just restart from scratch?

   Give a look at this:https://gcc.gnu.org/pipermail/gcc/2021-April/235367.html

   Relying on #GNU (and on US-based software) is becoming a huge hazard.

   Or more precisely, it's just proving to be such hazard and we were to naive to realize before.

   We need to rebuild everything from scratch, anything that cannot be completely rebuilt in a month must be rewitten.

   So what's the point of compatibility?

     @ekaitz_zarraga

     Did you look at https://git.simple-cc.org/scc/file/README.html

     The website it so minimalist it's hard to do anything but contact the developers: https://www.simple-cc.org/

     @ekaitz_zarraga

     I know nothing about it.

     I've just found it on suckless.org among the software that rocks.

     Yet seems to support amd64 and even run on plan9

     @ekaitz_zarraga Btw, I managed to cross compile cat.c from Linux to #Jehanne with TinyCC and run it on Jehanne.

     This means that, to some extent, static linking works.

     ```tcc cat.c -m64 -nostdinc -nostdlib -g -I$JEHANNE/sys/include -I$JEHANNE/arch/amd64/include -L$JEHANNE/arch/amd64/lib $JEHANNE/arch/amd64/lib/crt* -ljehanne -static -Wl,-section-alignment=1000```

     I had to modify tccelf.c to use _main instead of _start as the elf starting point.

     Tricky.And a very little step forward (cat.c is very simple)

     But a little hope.

     Maybe the crt0.s and friends here might be useful (but they are x86_64 and specific of Jehanne) https://github.com/JehanneOS/jehanne/tree/master/sys/src/lib/jehanne/amd64

     @ekaitz_zarraga they basically setup things that must occurs once just after a program exec()uted starts, like initializing the c library.

     But the only thing that crt0.s HAVE to do is to setup argc and argv and then call main() (in Jehanne it calls __jehanne_libc_init that will call main)

     @ekaitz_zarraga @theruran

     AFAIK they are provided by the C library (and usually also depends on the target architecture and os)

     @ekaitz_zarraga Have you looked thru mescc-tools? It's a lot simpler, though unforgiving, and needs RISC-V support. @Shamar@qoto.org
