Suvayu Ali commented on ARROW-3874:
-----------------------------------
Thanks for the link.
In the meantime, I tried to build with *Gandiva* on Fedora 29, and it failed to
detect LLVM (my original attempt was on F28, which was resolved by installing
the static libraries).
On F29 the default version is 7, while other versions like 6.0 are installed in
subdirectories (e.g. {{/usr/lib64/llvm6.0}}). Setting {{-DLLVM_DIR=/path}}
doesn't help, I had to add {{LLVM_DIR}} to {{find_package}} in
{{FindLLVM.cmake}}.
While the edit resolved the LLVM issue, cmake failed again unable to find
{{JAVA_AWT_JNI}} (don't remember exactly, not on F29 now). I couldn't figure
out if it was something missing, or if cmake was unable to detect again. I'm
unsure how to report this, do I update this bug report and change the platform
from F28 to F29, or do I close this and open a fresh one?
