Git version of EFL cannot be built on FreeBSD 11.2 (neither with autotools nor with meson).
../src/lib/ecore/efl_core_proc_env.c:34:8: error: use of undeclared identifier 'environ' if (environ)
Adding the declaration of 'environ' unblocks the build:
extern char **environ;
This isn't fixin anything.
Seems the environ symbol is found in /usr/lib/crt1.o.
I'm not sure if disabling errors upon unresolved-symbols would fix this?
So libc doesn't have environ symbol.
Tried LDFLAGS=--warn-unresolved-symbols suggestion from @q66.
vtorri, I don't think it's related as in the bug they discuss a runtime problem, but we have a build time problem. I've just declared the variable as 'extern' and the build passed, E works correctly with the compiled version of EFL (I'm using it since 2 days). BUT, I don't know if somewhere this function was used, so MAYBE we are concerned by 220103 bug too.
netstar, why can't we just declare the variable in case of FreeBSD build?
bbdb2e5c23139d96b6fa57633f9a73e85ea6e7d6 i hope should fix this. i also found a few other loose ends regarding environ related things and fixed those too. my fbsd vm tho is having other issues (meson cant find libintl.h and it isn't respecting CFLAGS when looking for libintl.h ...:() so my fix above is a guess, but a decent one based on the fact that efl_core_proc_env.c was indeed missing the extern char **environ declaration and uour comment above that it works.

Still does not build.
are you building with meson there? looks like it.
this seems to be a meson + bsd issue. meson insists on adding -Wl,-no-undefined by default. this forces compilation to fail when there are undefined symbols for shared libraries. it seems that bsd has some incompatibility with this as the environ symbol only comes from crt1.o or something like that when a BINARY is linked together.
this means efl works - it finds the same environ symbol in the calling binary at runtime, BUT the compilation fails because this symbol is unresolved at link time. it's a meson issue it seems but i found a workaround. use - -Dbl_undef=false as a config option to meson and it disables meson's insistence on the no-undefined option. this is something for meson to sort out i think in its bsd support but the way it works out of the box is incompatible with shared libs that access environ and meson as the compilation infra.
Sorry, the workaround does not work.
I deleted build directory and reconfigured meson with the proposed option.
The build still fails.

I used the following command to configure the build:
meson build -Dxinput22=true -Dharfbuzz=true -Decore-imf-loaders-disabler=xim,scim,ibus -Dsystemd=false -Deeze=false -Dbl_undef=false
err sorry
-Db_lundef=false
is it
typo.
here is the meson cofigure line i have in my fbsd build script:
-Db_lundef=false \ -Dxinput22=true -Dbuffer=false -Dfb=false -Ddrm=false \ -Dtslib=false -Dharfbuzz=true -Dwl=false -Dnetwork-backend=connman \ -Devas-loaders-disabler= -Dbindings=cxx,luajit -Dbuild-examples=false \ -Decore-imf-loaders-disabler= -Dsystemd=false -Deeze=false"
that worked until freebsd shot itself in the foot. don't get me started (a package update ended up with zsh failing to run - which is my login shell thanks to libdl.so.1 not being found so the packages broke their dependencies, then i tried an upgrade to freebase 12 ... and that ended up with even more freebsd shooting itself in the foot - it ended up with pam errors and sudo not working then now i log in as my user and i end up being root -i can't access my user anymore... pkg has shot itself in the foot too - it thinks pkg is not installed but i say yes to install it and then it still thinks its not installed. i give up. freebsd is so fragile that you just look at it sideways and it shoots itself in the foot :(- long story short - my freebsd vm fucked itself up and i frankly am not in a mood to try install freebsd again after it shot itself in the foot so much so you'll have to trust me that the above worked and got an efl build done - at least until freebsd fell over :))

i couldn't say anymore - fbsd has since my build shot itself in the face. perhaps i did have some inotify lib installed... but i managed to build efl, e, rage and terminology...
If I remove libinotify I get another error:

2 warnings and 1 error generated.There is a thread in FreeBSD forum about porting polybar, they had libinotify problems too...
https://forums.freebsd.org/threads/polybar-i-want-to-give-it-a-try.62494/
...and a commit to add FreeBSD libinotify support to gerbera:
https://github.com/gerbera/gerbera/commit/3cec05f3b615b768f4dc0caff7defa549b489e23
FreeBSD doesn't have inotify and if you start building EFL on a desktop machine where you pull in things like GIMP, it'll pull in inotify emulation with an inotify.h header that will break your build.
EFL here builds with these options:
LDFLAGS=-L/usr/local/lib -Wl,--warn-unresolved-symbols CFLAGS=-I/usr/local/include meson build -Dsystemd=false -Deeze=false -Dbuild-examples=false
I found another issue with elementary_codegen examples being built. It' s a lot simpler for now to just disable examples with meson/ninja. Will close this ticket. @Peter2121 if you have time making a ticket for the elementary_codegen breackage would be cool (sorry I don't have the time right now).
Sorry, netstar, the problem explained in this post is still present, building with your options.
Errors about inotify_* changed to warnings (will it run correctly after build?)
EFL builds here. It's FreeBSD-12.0. Make sure you remove any package that is including inotify headers because the EFL build will see these headers and assume we can use inotify but we cannot use it on FreeBSD. If you have inotify.h in /usr/local/include or elsewhere, remove it, or the package that is pulling in this bogus header.
Try a clean tree, and with only the dependencies installed that EFL depends on. Else you can end up in a situation like above where, for example, GIMP will include some inotify emulation and a header to confuse any build system. FreeBSD does NOT have inotify support (for now).
Then with a clean tree:
setenv LDFLAGS "-L/usr/local/lib -Wl,--warn-unresolved-symbols" setenv CFLAGS "-I/usr/local/include" meson build -Dsystemd=false -Deeze=false -Dbuild-examples=false
you can add this. If notify is usually in libc, then AC_CHECK_LIB should be sufficient (same for meson)
netstar,
Make sure you remove any package that is including inotify headers because the EFL build will see these headers and assume we can use inotify but we cannot use it on FreeBSD. If you have inotify.h in /usr/local/include or elsewhere, remove it, or the package that is pulling in this bogus header.
It seems really hacky. So, an average user who has GIMP installed (or OpenJDK or ...) needs to delete headers from /usr/local/include?? Something is going bad with the meson here...
Same thing
LDFLAGS "-L/usr/local/lib -Wl,--warn-unresolved-symbols"
OK, I understand that -L/usr/local/lib should be here (BTW, why meson does not detect this path himself? It's an advanced build system, isn't it?) But --warn-unresolved-symbols seems to be hacky as well.
I'll retry a clean build this evening, but anyway - build EFL now is not a problem (I've built it using autotools), I'm just trying to help with this new build system. So if you consider that it's OK in the actual state - no problems, it's up to you to close the ticket.
Okay, i see three issues here:
In general regarding environ: I cannot understand why freeBSD acts in such a way regarding environ. Why is the symbol only injected when *running* a appliction? This is the complete opposite of what the rest does, and i seriously cannot find a single reason to do that ... Further more, it forces you to not check for unresolved symbols whenever you use environ.
bu5hm4n,
Libinotify is present in FreeBSD as port:
FreshPorts
You can see the limitations of this library in pkg-message section of this page. This library is used for 50+ ports and they manage to use it correctly. I referenced two projects that added support of FreeBSD's inotify without hacks: polybar, gerbera It does not seem to me that they needed to work hard to add this support ;) Anyway, if EFL cannot use it correctly under FreeBSD - we need a meson option to disable it without removing headers.
As about environ - I don't understand it neither.
It does not matter if we work hard for it or not. inotify.h is a linux thing, which requires *no* -l argument, hense most projects build without a check to the library (It will fail anyways on linux). So here we are once again at the point where the distribution should probebly add a note somewhere that they require custom CFLAGS, to link against this custom libinotify.
However, i am going to disable the inotify backend for BSD, then we got rid of this.
So, I took my test PC (FreeBSD 12) , I've uninstaled all EFL stuff, I've cloned EFL repo and I've patched src/lib/ecore_file/meson.build like in Diff 19894.
Then I've declared the following environment variables:
LD_LIBRARY_PATH=/usr/local/lib CFLAGS=-I/usr/local/include CPATH=/usr/local/include LIBRARY_PATH=/usr/local/lib LDFLAGS=-L/usr/local/lib -Wl,--warn-unresolved-symbols
Then I've configured EFL as follows:
meson build -Dsystemd=false -Deeze=false -Dbuild-examples=false
Then I started the build
ninja -C build
And it still cannot build EFL:

If I do something wrong - tell me how should I proceed.
Libinotify is present on this PC, there are many packages using it.
I don't reopen the ticked as it works for netstar ;)
Sorry, i must have been half asleep when i wrote this patch, it must be if sys_linux == true. sorry :(
OK, with if sys_linux == true it works better ;)
I could build EFL, Enlightenment and Terminology, everything works fine on FreeBSD 12.
