ELFCLASS32 when compiling CMake on Solaris 11 - cmake

Question

I trying to compile CMake from sources on Solaris 11 machine:
# uname -a
SunOS 5.11 11.3 sun4v sparc sun4v
Steps:
wget
https://github.com/Kitware/CMake/releases/download/v3.25.2/cmake-3.25.2-linux-x86_64.tar.gz
tar -xzvf cmake-3.25.2-linux-x86_64.tar.gz cd
cmake-3.25.2-linux-x86_64 ./bootstrap --prefix=/opt/cmake-3.25.2
--parallel=$(nproc)
After few time next error occurs:

How to compile properly?

Answer 1

EDIT: Bare in mind that the tarball cmake-3.25.2-linux-x86_64.tar.gz contains precompiled 64bit binaries.
As #Tsyvarev pointed out you are producing 32bit objects. Because you are building on solaris it might be related to the fact that Solaris provides libraries for different architectures. Due to this your linker is probably picking up the wrong binaries.
Possible fixes:
Make sure that the linker picks up only the right binaries (64bit)
Get CMake which is provided by the package manager of Solaris and build from source files. (official)
Use an unofficial CMake package [like this one here]
The official package might be outdated. The unofficial one is well, unofficial.
