compiling our samba with gcc 4.2.1 in 12 gave us some off behaviour
when lld became the linker I think..
1/ linking needed some directories added to some of the build scripts
because previously apparently it looked in $SYSROOT/usr/lib by default
and now it doesn't.
2/ compiling our samba produces a libtdb.so that has various symbols
in it, (according to nm(1) ), but when we try link against it we get
complaints about those symbols not being defined.
3/ an attempt to switch to using clang to compile everything leads to:
"--aes-accel=intelaesni selected and compiler rejects -Wp,-E,-lang-asm.
One wonders whether there is a clang equivalent of "-Wp,-E,-lang-asm"
The AES acceleration is a configure option for the samba package.
Apparently turning it on requires -Wp,-E,-lang-asm.
which apparently gcc 4.2.1 has, but clang doesn't have.
FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based
on LLVM 6.0.1)
Target: x86_64-unknown-freebsd12.0
Thread model: posix
InstalledDir: /usr/bin
anyone know if there is a clang equivalent of -Wp, -E,-lang-asm?
possible work arrounds include:
1/ Get gcc/lld to produce a library from which lld can find the symbols
2/ find a way to compile this with clang but everything else with gcc?
3/ find a way to allow clang to use
-Wp,-E,-lang-asm
whatever that means
Thoughts from any tools people?
Julian
