NetBSD  10.1 NetBSD 10.1 (GENERIC) #0: Mon Dec 16 13:08:11 UTC 2024  mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64

>Description:
Here is a reproducer trying to build things "normally" and then with @command-line-arguments. Both are using -lnonexistent, which should be removed by cwrappers config, but isn't in the second case.

A package (mongodb) was using this syntax to avoid exceeding max command line length.

#!/bin/sh

set -ex

cat << EOF > main.c
int main() { return 0; }
EOF

cat << EOF > cc
worklog=.work.log
exec=/usr/bin/cc
exec_path=/usr/pkg/libexec/cwrappers/cc-wrapper
transform=rm:-lnonexistent
EOF

cat << EOF > mainlink
main.c -lnonexistent
EOF

# Normal command, works fine
env CWRAPPERS_CONFIG_DIR=. /usr/pkg/libexec/cwrappers/cc-wrapper main.c -lnonexistent

# Same command passed with '@mainlink', transform doesn't work
env CWRAPPERS_CONFIG_DIR=. /usr/pkg/libexec/cwrappers/cc-wrapper '@mainlink'

 Log Message:
 mongodb: Introduce workarond for PR pkg/59842

 cwrappers doesn't transform when `cc @args` syntax is used (to avoid very
 long commands). Tell the package we can handle the long commands so this
 syntax isn't necessary.

 Build failure seen on NetBSD-10/x86_64 - which relies on pkgsrc GCC, which
 relies on cwrappers transform.
