I am finally ready to compile shibboleth 2.2, sparc solaris 10, native apache 2.0 and ssl for now.
I was able to successfully compile the prerequisites with the scripts specified on the page NativeSPSolaris10SourceBuild
I see a difference on that site about compiling Shibboleth and the site NativeSPSolarisSourceBuild with regards to flags. This page specified I need CFLAGS="-D_sparc_" CXXFLAGS="-D_sparc_ -library=Cstd,Crun" LDFLAGS="-lz" for sparc.
Are those flags necessary. I was going to use this from the page NativeSPSolaris10SourceBuild, just to be consistent.
