[cfe-dev] APFloat.cpp compile error, Solaris10/gcc 3.4.3

[Martin Carpenter]

Hello,

I checked out trunk from SVN, error compiling APFloat.cpp on Solaris
10/x86 with gcc 3.4.3 (stock install). Solaris10/SPARC/gcc is listed
"known to work" at http://llvm.org/docs/GettingStarted.html.

I tried Oracle Studio 12.3 (setting CC/CXX) but configure fails:
checking tool compatibility... configure: error: gcc|icc required but not found

The same sources compile fine under Linux/gcc 4.6. So perhaps I need to try
a later gcc under Solaris? Or is this a LLVM/clang bug? 


Thanks,

Martin.
