Linux from Scratch 10.2.0 gcc fails

Hey guys i tried building gcc with Linux from Scratch 10.2.0. I followed the instructions exactly, but the make command throws following Error:

Maybe somebody can help me. If you need any aditional information dont hestitate to ask.

It seems like the package you are trying to build (ahem configure) is broken.

That happens sometime because it's almost impossible to check all possible dependencies are building correctly. Bad luck!

So, the compiler is telling you that it can't understand the file /usr/share/texinfo/Texinfo/ParserNonXS.pm You have two options here:

• either you find out what configure switch requires texinfo and disable it (something like ./configure blablabla --disable-texinfo)
• either you fix the file /usr/share/texinfo/Texinfo/ParserNonXS.pm by manually editting it and adding the missing line my $lineWnr at line 5205. This is likely a Perl script so a bit of perl knowledge is required here no to break the file.

Since you're doing a LFS build, I guess your Texinfo package should match the one expected by your GCC package. Old GCC require an old texinfo package and newer GCC requires a newer texinfo package. If you don't have texinfo, you should install this first.
