Subject: [Buildroot] [Bug 15718] New: Cross-compiler called through toolchain-wrapper generates bogus error messages
Date: Fri, 11 Aug 2023 00:54:26 +0000 [thread overview]
Message-ID: <bug-15718-163@https.bugs.busybox.net/> (raw)
https://bugs.busybox.net/show_bug.cgi?id=15718
Bug ID: 15718
Summary: Cross-compiler called through toolchain-wrapper
generates bogus error messages
Product: buildroot
Version: 2023.02
Hardware: All
OS: Linux
Status: NEW
Severity: trivial
Priority: P5
Component: Other
Assignee: unassigned@buildroot.uclibc.org
Reporter: jimgeorge@gmail.com
CC: buildroot@uclibc.org
Target Milestone: ---
Cause:
Invoking the cross-compiler from the package generated by 'make sdk' with no
arguments
Expected behavior:
Should print arm-linux-cc: fatal error: No input files
Observed behavior:
Output is:
/path/to/buildroot/output/host/lib/gcc/arm-buildroot-linux-gnueabihf/11.3.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld:
/path/to/buildroot/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/Scrt1.o:
in function `_start':
(.text+0x40): undefined reference to `main'
collect2: error: ld returned 1 exit status
With BR2_DEBUG_WRAPPER set to 2, I get the following extra information:
Toolchain wrapper was called with:
'buildroot-ts/buildroot/output/host/bin/arm-linux-cc'
Toolchain wrapper executing:
'/path/to/buildroot/output/host/bin/arm-linux-cc.br_real'
'--sysroot'
'/path/to/buildroot/output/host/arm-buildroot-linux-gnueabihf/sysroot'
'-fstack-protector-strong'
'-fPIE'
'-pie'
'-Wl,-z,now'
'-Wl,-z,relro'
When invoking arm-linux-cc with an example program to compile, behavior is
normal. It seems like the 'Wl' options are what trigger the errors from the
underlying gcc. Adding this as a 'trivial' bug so that it could either be
documented or calling toolchain-wrapper with no arguments is special-cased so
other buildroot newbies aren't tripped up by this.
