It's usually unrecoverable for clang, and the only way to debug it is to turn on the option to write messages to stdout/stderr. I never got around to ask it, but is there a way to get these error messages even when the TU is null? I mean, the only way for e.g. an IDE to handle this is to silently ignore it, and that's not very helpful...</div></blockquote><div><br></div><div>How about introducing a new CXTranslationUnit_ flag to pass to clang_parseTranslationUnit, which will cause that function to still return a CXTranslationUnit object on failure (maybe marked as erroneous or something) which the client will only use to get any stored diagnostic.</div><div>I think we also need some changes in ASTUnit because I believe that if clang::createInvocationFromCommandLine fails we don't keep the diagnostic.</div><br><blockquote type="cite"><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><br></div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">-- Erik. </div></blockquote></div><br></body></html>
