On FreeBSD 10.0-STABLE leveldb within eleveldb cannot be built with clang (use gcc from Ports to circumvent) [JIRA: RIAK-1808]

[jj1bdx]

Tested on

• Commit 63733a9
• Compiled on FreeBSD 10.0-STABLE r261910 amd64 with Erlang/OTP R16B03-1

Synopsis summary:

• FreeBSD 10.x clang compiler seems to fail to process some include files in leveldb/
• Note that running cd c_src && ./build_deps.sh switches the compiler to g++ (GNU cc) and no error will occur (because my system has gcc 4.6.4 installed from the Ports)
• Building with env CC=gcc46 CXX=g++46 gmake clean will build runnable binaries

----------------------------------------------------------------------
Libraries have been installed in:
   /home/kenji/src/eleveldb/c_src/system/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

[matthewvon]

Is this issue resolved?

[jj1bdx]

This issue hasn't been resolved

[jonmeredith]

Thanks Kenji - reopening so we remember.

[jj1bdx]

@jonmeredith: I found that some part of eleveldb still used a hardcoded g++ for compiling C++ code today. On FreeBSD a gcc exec binary is called g++48 (or with other numbers for other versions), and since 10.0-RELEASE, there's no stock g++ anymore in the base distribution (it's clang-based c++). FYI.

[jj1bdx]

@jonmeredith See basho/leveldb#156 for a proposed fix.

[essen]

Seeing this same issue.
