Category:	MySQL Server: Compiling	Severity:	S1 (Critical)

Description:
No matter what I do the compile fails. The only way to make this compile is to pass nothing in the CXXFLAGS. As soon as I pass something the compile fails.

My Machine is Quad Core Opteron Dual Processor  with 4GB of RAM running CentOS 5.2.
gcc -v
Using built-in specs.

How to repeat:
export CFLAGS="-O3 -march=opteron -pipe -msse2 -m3dnow -fomit-frame-pointer -mtune=opteron" 
export CXX="gcc" 
CXXFLAGS="-O3 -opteron -felide-constructors -fno-exceptions -fno-rtti"

make

Suggested fix:
only way to fix this is to make CXXFLAGS=""
and this results in a binary which is not properly optimized I guess.

The error I get is too few arguments to function `gethostbyname_r'

Thank you for the report.

Do you get same error if CXX is g++?

I am not sure. I did not try I will have to check with g++.

You don't show the actual error message, but I suspect the problem is that
you give "-opteron" in CXXFLAGS, not "-march=opteron" as in CFLAGS.

If I'm incorrect, please reopen this bug, and include the actual error
message. If it is configure that fails, please attache "config.log", if
the compilation please paste the failing text in the bug report.
