As part of the Compile --pure testing, I tried upgrading GCC to 9.3.0 and compiling it, but I get this libtool-related error which strikes me as a bit odd?:
make: Nothing to be done for 'install-data-am'. /System/Index/bin/mkdir -p '/Programs/GCC/9.3.0/lib/../lib' /bin/sh ../libtool --mode=install /System/Index/bin/install -c liblsan.la '/Programs/GCC/9.3.0/lib/../lib' libtool: install: error: cannot install `liblsan.la' to a directory not ending in /usr/lib/../lib make: *** [Makefile:498: install-toolexeclibLTLIBRARIES] Error 1 make: Leaving directory '/Data/Compile/Sources/gcc-9.3.0/_build/x86_64-pc-linux-gnu/libsanitizer/lsan' make: *** [Makefile:666: install-am] Error 2 make: Leaving directory '/Data/Compile/Sources/gcc-9.3.0/_build/x86_64-pc-linux-gnu/libsanitizer/lsan' make: *** [Makefile:527: install-recursive] Error 1 make: Leaving directory '/Data/Compile/Sources/gcc-9.3.0/_build/x86_64-pc-linux-gnu/libsanitizer' make: *** [Makefile:11215: install-target-libsanitizer] Error 2 make: *** Waiting for unfinished jobs....
Since you guys are probably used to dealing with stuff like this, I figured I might as well ask.
EDIT: Forgot to add that
Compile also needs Flex and Bison as Dependencies and that GCC needs LibXML2 too.
