Finally, my #Linux-native #GNU toolchain for #FreeBSD's #Linuxulator works for C and C++ on #aarch64, #amd64 and #i386 🥳
I guess that's a good time to actually announce the ongoing project!
https://lists.freebsd.org/archives/freebsd-ports/2023-August/004263.html
And now, we have a working #Linux #bash running in #FreeBSD's #linuxulator
Which also finally makes the "ldd" script installed by #glibc work 😎
Ok, enough for today 😉

Today's progress: #GNU #coreutils and glibc's localedata seem to work fine in #FreeBSD's #Linuxulator, in addition to bash.
Still, coreutils is not complete yet, it *should* use hash functions from #OpenSSL, so, time to port that for #Linux (tomorrow).
Today's achievement: We now have #OpenSSL (and #GNU coreutils built using it), plus grep, sed, awk, make, groff *and* man-db in #FreeBSD's #Linuxulator userland.
But there's a catch 😞 It doesn't build with #poudriere any more. Can be patched, and I guess I should soon look into getting this fixed... (**edit**: See answer, somewhat working without a patch now!)
For details, see here:

Good news, I found a workaround without patching poudriere, my branch is updated!
poudriere-testport will probably fail, but poudriere-bulk works this way.
In case anyone tried and wondered why the branch is currently broken 🙈
I'm working on adding a new USES for this #Linuxulator userland. It should hide all the "crap" needed to build it, and also help with creating new ports, either *for* it (e.g. shared libs), or just using it.
So I have to rework each and every port now, including test builds...
Right now, I'm test-building "native" gcc ... for the third time 😂 so, native toolchain almost complete again.
I hope to get the branch into sane shape tomorrow!
Userland built from source for #FreeBSD's #Linuxulator is making progress again (and yes, my branch builds and works again!)
☑️ Metaports "linuxsrc_base" for a minimal base userland and "linuxsrc-devtools" for minimal basic tools needed to build #Linux software (just C and C++ and some common tools)
☑️ Automatic selection of the Linux kernel version based on target FreeBSD version, overridable in DEFAULT_VERSIONS (but checked for compatibility of course)
☑️ A new "USES=linuxsrc" to do all the ugly "plumbing" needed for building Linux software using FreeBSD #ports, offering different configurations.
Guess now I could start adding some optional packages and try to get some *real* Linux application working 😎

Spent this day (besides work, hehe) simplifying a few ports and hunting down a few bugs and now, it all builds fine on all supported target systems (#FreeBSD {13.2,14.0}/{aarch64,amd64,i386}). Yay.
So, just tried to create a *very* first port in "dist" mode (installed to Linuxulator prefix, but not part of the "base" system).
Well, I guess the "interesting" issues just begin 🙈

Hitting the next roadblock in my #FreeBSD #Linuxulator "userland from source" project: #Linux #Python is causing trouble. I got it to build and package, but runtime paths are wrong, *somehow* the "/compat/linux" prefix "sneaks in" 😞 (still didn't understand how exactly...).
You might ask why port python at all, and indeed, I didn't plan to do so initially.
The issue is build systems. With the goal to port shared libraries that might be needed by (closed-source) Linux binaries, not all of them use plain #make (or #GNU #autotools) for building.
#cmake is popular, so I'll need it. To build it using shared libraries itself, one of its prerequisites needs #meson, which, in turn, requires python. 🤯
Ahh, welcome to dependency hell 😜
Python issue solved the "redneck repair" way, installing *everything* to /usr/lib64 (on a 64bit system) instead of *just* the architecture-dependent stuff. Now, python works and finds all its modules... 🙄
After porting lots of extra python tools (cause #pip won't do it for proper packaging with staging), it seems I finally have a working #meson in my #FreeBSD #Linuxulator userland 🥳
Nevermind all these extra modules install to /usr/lib. Well, it works, I don't care 😂
Doing a full rebuild of all the #Linux ports now just to be sure (cause I also changed stuff in my USES). If all is fine, branch will be updated 🙏
