[Opalvoip-devel] Opalvoip-opal 3.18.8 release compilation error on RedHat 8.6 Enterprise

[Oleh V. <vas...@gm...>]

Hello,

I need to compile PTLib 2.18.8 and Opal 3.18.8 release on RedHat Enterprise
8.6.
Gcc and g++ version:
 ggcc --version
bash: ggcc: command not found...
Similar command is: 'gcc'
[fiolevasy@localhost opalvoip-opal]$ gcc --version
gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-10)

I configured and compiled PTLib with parameters:
  ./configure --enable-cpp11 --disable-v8 --prefix=/usr
Opal:
 ./configure --enable-cpp11 --prefix=/usr

I see that PTLib 2.18.8 added a new class for replacing STD::auto_ptr
PAutoPtr.
This class causes the error in Opal library compilation:

I can try to fix this error but I don't understand why I have such an error
for the release. What can be wrong in my build process?

Best regards,
Oleh Vasyura.
