[CMake] Sun GCC builds (cooltools)

[George Neill]

Hi CMakers,

I am building cmake on a Sun Enterprise 220R with 2GB of RAM running
Solaris 10 08/07.

I have two compilers installed on this box.

1.  SunStudio 12

-bash-3.00$ /opt/SUNWspro/bin/CC -V
CC: Sun C++ 5.9 SunOS_sparc Patch 124863-01 2007/07/25


2. The SUN modified gcc compiler v4.2.0 -- http://cooltools.sunsource.net/gcc

sparc-sun-solaris2.10-gcc (GCC) 4.2.0 (gccfss)

When compiling with #1,  bootstrap / make ... worked and all tests
passed for both in-source and out-of-source bootstrap builds.


When compiling with #2,  an in-source ./bootstrap fails with the
following error

export CC=/opt/gcc/bin/gcc
export CXX=/opt/gcc/bin/g++
cvs co CMake
cd CMake
./bootstrap

.
.
Undefined                       first referenced

ld: fatal: Symbol referencing errors. No output written to cmake


however an out-of-source bootstrap appears to succeed,

cvs co CMake
mkdir CMake.build
cd CMake.build
../CMake/bootstrap

... but make then fails with,

'Curl_strerror':

*** Error code 1

I am willing to set up nightly builds on this machine and report
results to the cmake dashboard ... if you are interested.

Thanks,
George.
