I am having the same issue. --use-cc
is also unrecognized.
I am trying to compile with a different CC
, and getting an empty comile_commands.json
.
I have a simple makefile
CC = /usr/local/opt/llvm/bin/clang
buggy: zero.c buggy.c
$(CC) -o buggy $^
and the following config file
{
"compilation": {
"compilers_to_recognize": [
{
"executable": "/usr/local/opt/llvm/bin/clang",
"flags_to_add": [],
"flags_to_remove": []
}
],
"compilers_to_exclude": []
},
"output": {
"content": {
"include_only_existing_source": true,
"paths_to_include": [],
"paths_to_exclude": []
},
"format": {
"command_as_array": true,
"drop_output_field": false
}
}
}
running bear --verbose --config config.json -- make
gives

Running with the default CC
works perfectly fine.
@hanyazou the flags you try to use are for the 2.3.x
and 2.4.x
versions. (As the #279 ticket was raised against those versions.) The solution for the latest 3.x
version is what @kay-22 is doing: create a config file and name the compiler you would like to catch.
@kay-22 for you the solution is to not define the CC
inside the makefile, but pass it as environment variable. Something like this:
CC=/usr/local/opt/llvm/bin/clang bear --config config.json -- make
while your makefile is only this:
buggy: zero.c buggy.c
$(CC) -o buggy $^
@rizsotto Thank you for your comment.
The solution for the latest 3.x version is what @kay-22 is doing: create a config file and name the compiler you would like to catch.
I've tried bear with some config file. The output was empty. The intercept which spawned did not seem to catch the compiler. What was wrong with my configuration?

hello.o: hello.c

@hanyazou your make file should allow to interpose the compiler. Change it into this...
hello.o: hello.c
$(CC) -c hello.c
and call it as...
CC=/usr/local/bin/arm-none-eabi-gcc bear --config config.json -- make
I presume it will work without the config file too...
CC=/usr/local/bin/arm-none-eabi-gcc bear -- make
Okay, so the make must spawn just 'cc' command instead of real compiler? I could understand how the bear works though I have difficulty to change the Makefile(s) with huge complex build system.
Thank you.

It is executing the real compiler (as you have seen in the output), but the build file just refers the environment variable that contains the compiler name.
I could understand how the bear works though I have difficulty to change the Makefile(s) with huge complex build system.
@hanyazou the build should be open to configure the compiler. (And usually it's like that for "huge complex" projects. See GCC or the Linux kernel source.) It's considered a bad practice if the build "hardcode" the compiler (or it's path).
If your build is using a configuration step (./configure
in GNU autotools), run Bear against it too. (See more here.)
@rizsotto

True.
This works perfect for my current project. The build system determine which compiler should be used depending to the target specified. But I could override the compiler with CC=cc.
% CC=/usr/local/bin/arm-none-eabi-gcc bear -- make CC=cc
Your tool is very helpful. Thank you.
Expected behavior
I expect it to catch the arm-none-eabi-gcc command, but it doesn't seem to be.
Environment:
OS name: macOS OS version: 11.5.2 OS architecture: x86_64 Bear version: bear 3.0.19 Bear install method: brew install bear
Additional context
Could you tell me how to handle a cross compiler with the intercept? The output file compile_commands.events.json was empty if I run the bear with a cross compiler arm-none-eabi-gcc. I read #279 and tried the --use-cc command line options. But the output was "Unrecognized parameter". The configuration file which is explained in the man page of citnames does not seem help because the bear will spawn the intercept without the --config option.
The only way in which the bear could handle cross compiler was that I made a symbolic link in the wrapper.d directory to tell the bear the cross compiler should be hooked. But I feel this was not a proper way to do that.
