build-lib build-exe missing -nostdinc -nostdlib about zig HOT 6 CLOSED

I think that works, thanks!

from zig.

is this not the default behavior when you dont pass -lc?

int main() {}

compiling this with gcc/clang and passing -nostdlib -nostdinc will give a linking error about not finding _start and segfaults if you try to run the program. the exact same thing happens when running zig build-exe with no additional flags.
is the difference something to do with different platforms?

edit: this was possibly not the best way to represent it but my point is that without -lc zig doesnt use any of the standard library. if you try to include any libc headers it will fail as well

from zig.

So it was my understanding (and I believe observation, though I don't have a neatly packaged test, so the observation could be suspect) that nostdinc and nostdlib also removed default search paths for includes and libraries, e.g. /usr/include /usr/lib etc.

from zig.

thats my understanding as well which as far as im aware is the same behavior for zig unless youre linking libc. though interestingly i just tested and gcc seems to keep the library search paths, if i do e.g. gcc a.c -nostdinc -nostdlib -lraylib it is still able to link raylib as well as libc and libm etc.

hmm..so in my use case I am often linking libc, but I don't want zig to go searching /usr for headers and libraries for other things (headers mostly; libraries I have more control over because I'm often building static archives and explictly passing the .a instead of using -l, though sometimes it'd be nice to pass a command-line to CC= somewhere and know that it will only look where I told it to). I think if I explicitly specify -target (even if it is for the current host platform) it won't go looking, is that right?

Try:

zig build-lib -cflags -nostdlib -- <zig-flags> -cflags -nostdinc -- file.zig
