I'm trying to understand how to make a compile database. I can't switch to<br>
cmake because my very large project uses gmake. So I've made a python<br>
program to create a compile_commands.json file. It seems to have the right<br>
information. For one file, named "x/y.cpp", when I cut the "command" value<br>
out of the compile_commands.json file for "x/y.cpp" and execute it in a shell,<br>
the command executes as I expect it to. However, when I try to run<br>
"clang-check"<br>
I get various odd errors. Here's the complete situation:<br>
<br>
1.) The compile_commands.json file is in /a/b/c/compile_commands.json. I<br>
Think that makes "/a/b/c" the build directory in clang Tooling terms.<br>
2.) The source file is in /a/b/c/x/y.cpp.<br>
3.) The entry in compile_comands.json is:<br>
{"directory": "/a/b/c", "command": "clang++ x/y.cpp ... stuff<br>
...", "file": "/a/b/c/x/y.cpp"}<br>
And of course there are many entries. This is just one of hundreds.<br></blockquote><div>Do you separate them with commas and put brackets around the whole construct? I.e., does your file look like this:</div></div>

When I run clang-check, as the documentation seems to imply, using -p to name<br>
the build directory, I get this:<br>
<br>
% cd /a/b/c<br>
% clang-check -p . x/y.cpp<br>
Processing: /a/b/c/x/y.cpp.<br>
error: no input files<br>
error: unable to handle compilation, expected exactly one compiler job in ''<br>
Error while processing /a/b/c/x/y.cpp.<br>
<br>
Note: I get the same behavior putting the full path name for ".", when eliminate<br>
the "-p build_dir" completely. I also get the same behavior<br>
when I cd into<br>
x and run the experiments (with y.cpp in place of x/y.cpp, of course).<br>
<br>
Why am I being so dense about this? What am I missing? This seems very<br>
unintuitive. I'm trying to build a tool which extracts dependence<br>
information, but<br>
I'm stymied right at the beginning.<br>
