Target triple changed between intercept and Analyze : FreeBSD > Linux

Describe the bug I am cross compiling a binary and dependencies using BSD Make

Host is Ubuntu 16.04,x64 Target is FreeBSD 11,i386 Target build is done using Clang 5 - internal revision. Analysis is done using Clang 9, release branch.

LLVM supplied intercept-build is used to generate the compilation database JSON file since CodeChecker throws error due to LD_PRELOAD of “”. We mix 32 and64 bit tools in the build process.

This is the intercepted build command (collected from ‘build-action’ in results/failed/)

–target=i386-unknown-freebsd changed to --target=x86_64-unknown-linux-gnu in the analysis invocation.

Is this expected ?

To Reproduce Steps to reproduce the behavior

  1. intercept-build --cdb $OUTFILE bmake
  2. CodeChecker analyze --keep-gcc-include-fixed --ctu --analyzers clangsa --enable-all --enable alpha --enable valist --enable unix -jnproc $OUTFILE -o $CCRESULTS
  3. Go to results/failed and see any of the failed zip files
  4. See errors
/[path masked]/i386-unknown-freebsd11.0/usr/include/c++/v1/__config:169:10: fatal error: 'features.h' file not found
#include <features.h>


error: no member named '_IO_read_end' in 'struct __sFILE'
    return (fp->_IO_read_ptr < fp->_IO_read_end);
                               ~~  ^
  1. The ‘features.h’ and ‘_IO_read_end’ specific code are guarded to be compiled under Linux only.

when doing the analysis with CodeCheker log result - things are working as expected. Closing the issue.

Sorry for the confusion. Most likely, I forgot to rebase when I tried this out. I do see the correct target with the latest master.

Great news that it works in your environment @Xazax-hun
