Intel build fails with git pull from 20161009

Hello...

I've pulled the latest changes from git today to build a generix x86_64 image on a Debian 8 x86_64 box...but the build fails with:

Code

[ 42%] Linking C static library libz.a
Error running link command: No such file or directory
CMakeFiles/zlibstatic.dir/build.make:458: recipe for target 'libz.a' failed
make[3]: *** [libz.a] Error 2

But "link" is installed under /usr/bin/link...

It's not failing to run a command named link, but the linker as in the above "Linking C static library libz.a". That would be either a gcc or ld command, perhaps there's other hints in the full error output or in the build directory for zlib.

davorin Just do a full rebuild.

I successfully build master over night on Ubuntu.

Did a make clean and after that I get:

Code

[ 12%] Building AttributesCompatFunc.inc...
../../NATIVE/bin/llvm-tblgen: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ../../NATIVE/bin/llvm-tblgen)
lib/IR/CMakeFiles/AttributeCompatFuncTableGen.dir/build.make:88: recipe for target 'lib/IR/AttributesCompatFunc.inc.tmp' failed
make[3]: *** [lib/IR/AttributesCompatFunc.inc.tmp] Error 1

Is there no "./configure" like option before the build?

Looks like llvm-tblgen is built against the host libstdc++, but when it runs it's trying to use Debian's libstdc++. Possibly related to this commit. Solution could be to add the host librar path to LD_LIBRARY_PATH when running llvm-tblgen.

**vpeter** · October 11, 2016 at 7:48 AM

I think llvm-tblgen should also be compiled from host like llvm-config in this commit.

To make full rebuild I usually just delete build directory of the project - build.LibreELEC-ProjectName.xxxxxx.

Did a fresh clone..but fails at the same stage on Debian 8...

Trying now with the LLVM build settings OFF...
[hr]
Nope..even with old package.mk from LLVM it fails at the same stage...

No luck at all...

Is this really true Debian is suddenly unsupported as a build platform?

**vpeter** · October 14, 2016 at 5:55 PM

For LLVM use this package.mk or PR838 .

BTW...This has been fixed in recent days...compiles just fine now
