Date: Sat, 16 May 2020 16:40:10 +0000 [thread overview]
Message-ID: <bug-12911-163@https.bugs.busybox.net/> (raw)
https://bugs.busybox.net/show_bug.cgi?id=12911
Bug ID: 12911
Summary: usb_modeswitch installation race condition
Product: buildroot
Version: 2020.02.2
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: jharjuma at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
In usb_modeswitch Makefile dispatcher-script, dispatcher-dynlink and
dispatcher-statlink are .PHONY targets. The result is that sources are compiled
also when install targets are called. USB_MODESWITCH_INSTALL_TARGET_CMDS calls
$(MAKE) which is a call to parallel make eg. make -j9. So the install phase can
install empty usb_modeswitch binary (happened once) if the compiler have just
cleared the binary and install command installs it before compiler writes the
binary. USB_MODESWITCH_INSTALL_TARGET_CMDS should call $(MAKE1).
