-----------------------+--------------------
Hello,
and attempt to use current (as of 2023-08-02) RSB source code to build 6
/rtems-llvm on Ubuntu 20.04 LTS failes in three steps:
(1) compilation of swig fails with:
{{{
+ export CC_FOR_BUILD CXX_FOR_BUILD CFLAGS_FOR_BUILD CXXFLAGS_FOR_BUILD
LDFLAGS_FOR_BUILD LDLIBS_FOR_BUILS LIBS_FOR_BUILS
+ /bin/cp /export/home/rtems/git/rtems/rtems-source-builder-
ref/rtems/sources/pcre-8.40.tar.bz2 pcre-8.40.tar.bz2
/bin/cp: cannot stat '/export/home/rtems/git/rtems/rtems-source-builder-
ref/rtems/sources/pcre-8.40.tar.bz2': No such file or directory
}}}
looks like swig depends on pcre hence try to build it, but it's not
downloaded at all. When I cheat and put required tarball into the source
directory compilation is able to proceed to compiling LLVM.
(2) however compilation of LLVM fails very quickly with:
{{{

}}}
and although RSB prefer to install its own tools like swig failing above,
I've gone ahead and install swig from Ubuntu package and rerun again.
(3) this time LLVM proceed to compilation and then fails with:

I guess whole this LLVM toolchain deserves update to 16.x before
investigating failure of more than 4 years old LLVM code here.
