Bear fails with qmake builds (empty compile_commands.json) about bear HOT 7 CLOSED

could you check a few things for me? run bear with debug mode. check out does it create empty json file? in case of yes, i need more input about your application compilation. in case of no, check out the debug output and search for the compiler calls for switch like -M. it most probably filtered out. check the config file is it the case? since this week there is an extra verbose switch on bear, to get an idea how bear filtering was working. please check man bear or bear -h for command line.

I'm using the config file from Git unchanged.

Here's the debug output:

[
{
"pid": "66107",
"ppid": "66106",
"function": "execv",
"directory": "/[path_to_my_src]/src/lib/dsd_core",
"command": "/Applications/Xcode.app/Contents/Developer/usr/bin/make"
}
]

bear: filtering statistic:
total number of child processes : 1
match as compiler : 0
match as source file : 0
match on cancel parameter : 0

thanks for the updates. i don't have the environment that you are testing, so i need your help. could you please verify that you are not using distcc or ccache? and also please make sure that it is actually does compilation. i mean you run make clean before you call bear -d -x -- make.

from bear.

No distcc or ccache. Yes I'm running make clean then make. My library is built correctly, but bear is not capturing the compiler invocation.

Thanks, that's good. Could you run the build with strace and send me the output to my email address?

for the record: tried to reproduce the error on arch-Linux with Qt 5.1.1., but it does not show up.

from bear.

confirmed that this is a bug. caused by the make program is using posix_spawn to execute the compiler.
