Hi,

I am trying to build gcc 10.2.0 on Linux targeting i486 dos.

I am using Debian testing, on amd64.

My host compiler is gcc 10.2.1

I did install binutils-djgpp 2.34 from Debian, but I also successfully compiled binutils djgpp 2.35 from upstream, using ./configure --target=i486-pc-msdosdjgpp --program-prefix=i486-pc-msdosdjgpp- && make -j32 && sudo make install

Configuring gcc went fine:


./configure --target=i486-pc-msdosdjgpp --program-prefix=i486-pc-msdosdjgpp- --disable-lto --disable-libstdcxx --disable-libada --disable-libquadmath --enable-serial-configure --disable-objc-gc --disable-libgomp  --disable-libssp  --disable-libatomic  --disable-libsanitizer  --disable-libquadmath-support  --with-system-zlib  --disable-libphobos --enable-languages=c --disable-libstdcxx-pch  --disable-nls  --disable-decimal-float  --disable-libhsail-rt  --disable-gcov  --disable-tls
