zig cc helloworld.c -o helloworld_zig_cc_trunk failed to create a binary on linux-x86_64
Zig Version
0.10.0-dev.4403+f9192adab
Steps to Reproduce
using current prebuild binary
using a default helloworld.c in /somewhere/hello/:
#include <stdio.h>
int main(int argc, char **argv) { printf("Hello World\n"); return 0; }
zig cc helloworld.c -o helloworld_zig_cc_trunk LLD Link... ld.lld: error: cannot open pwd: /somewhere/crt1.o: No such file or directory ld.lld: error: cannot open pwd: /somewhere/crti.o: No such file or directory ld.lld: error: cannot open pwd: /somewhere/crtn.o: No such file or directory
zig-linux-x86_64-0.10.0-dev.4357+b4e342459 fails also zig-linux-x86_64-0.10.0-dev.3475+b3d463c9e works
Deleting $HOME/.cache/zig does not change the failure
Expected Behavior
a binary that can be started
Actual Behavior
zig cc helloworld.c -o helloworld_zig_cc_trunk LLD Link... ld.lld: error: cannot open pwd: /somewhere/crt1.o: No such file or directory ld.lld: error: cannot open pwd: /somewhere/crti.o: No such file or directory ld.lld: error: cannot open pwd: /somewhere/crtn.o: No such file or directory
works fine for me on
0.10.0-dev.4369+1087e6776
Strange.... With the prebuild linux-x86_64 binary?

Sorry, i'm away from my laptop until next friday
there's so much going on there obv "pwd: /_s/" is not a valid path symlink different toolchains
any idea why it goes from

there's so much going on there obv "pwd: /_s/" is not a valid path symlink
/_s/ is a valid path on my system. Important thing is. while my pwd was /_s/hello/ and i tried to compile helloworld.c (full path: /-s/hello/helloworld.c), zig tried to find the crt startup files in the parrent directory of the current directory.
Using a subdirectory as build directory, zig was again searching the crt startup files in the parrent directory of the new build directory. (pwd: /_s/hello/_bin.zig/ zig wants to use /_s/hello/crt*.o)
different toolchains

No Idea.
Where can i find a list of the daily builds for a regression test?

Attached is a script, which i created to download available binary releases.
starting point for every commit is: rev_last download trials: rev_tests when no revision+commit_id is downloadable, increase rev_tests max. required value detected between 4056 and 3999
Still present in zig 0.10 release:
/somewhere/hello$ zig cc helloworld.c -o helloworld_zig_cc_0.10_release LLD Link... ld.lld: error: cannot open pwd: /somewhere/crt1.o: No such file or directory ld.lld: error: cannot open pwd: /somewhere/crti.o: No such file or directory ld.lld: error: cannot open pwd: /somewhere/crtn.o: No such file or directory
I tried with latest downloadable binary and different values for -O and -target: -target makes a difference:
this fails: $ zig cc helloworld.c -Os -o helloworld_zig_cc_thrunk $ zig cc helloworld.c -o helloworld_zig_cc_thrunk
this both works: $ zig cc -target x86_64-linux-gnu helloworld.c -Os -o helloworld_zig_cc_thrunk_gnu $ zig cc -target x86_64-linux-gnu helloworld.c -o helloworld_zig_cc_thrunk_gnu
this both works: $ zig cc -target x86_64-linux-musl helloworld.c -Os -o helloworld_zig_cc_thrunk_musl $ zig cc -target x86_64-linux-musl helloworld.c -o helloworld_zig_cc_thrunk_musl
Hope, that helps. $ zig version 0.11.0-dev.486+19dd6de18

There must be something wrong with the toolchain auto detection.
Probably zig fails to remember, which target libc/toolchain the autodetection selected (gnu libc in my case) in an early code stage, and later, when the target libc/toolchain is needed again, zig does another autodetection and pick a different target libc/toolchain (musl libc in my case)
My tests from 4.december ( https://github.com/ziglang/zig/issues/13185#issuecomment-1336523723 ) seems to prove that: Specify a -target, when using "zig cc" produces always a working executable for the selected libc/toolchain.
is this steal a problem? tested on the latest zig realease 0.13.0 and it worked? (linux fedora)
It works on my current system.
Unfortunately, the old system is no longer in use.
