Hi all,
I'm writing an auto-completion plug-in for Sublime Text 3 with a
compiled component in C++. The compiled component is written as a clang
tool living in llvm/tools/clang/tools/ and it links with the
clangFrontend library. The bridge between Sublime's Python interface and
C++ is pybind11.
So, for every suitable open buffer in Sublime I have a clang::ASTUnit
fetching completions for it. The preamble of each file definitely needs
to be precompiled otherwise fetching completions is too slow for serious
use.
When I construct a clang::ASTUnit via
ASTUnit::LoadFromCompilerInvocation (I build the invocation myself), and
I choose the parameter PrecompilePreambleAfterNParses to be 1, then I
sometimes get an assertion error involving clang::SourceManager, saying
that two SourceLocations don't come from the same SourceManager.
I don't know how to fix this problem, as I cannot pass my own
SourceManager anywhere. And it happens during construction of an
ASTUnit, so I cannot re-arrange calls anywhere. If anyone has an idea as
to what causes this then I'd be very interested, because I can't
continue developing this plugin unless I fix this issue.
I have found out that if I set PrecompilePreambleAfterNParses to 0,
everything seems to work fine. So, I'm guessing it has something to do
with precompiling the preamble somehow. The full stack trace of the
assertion error is below. If someone needs more info like local
variables I can provide that too.
Regards,
Raoul Wols
