Hi all, I try to build gcc (9.3.0) from source on ubuntu focal using the following configure call: ./configure --enable-shared --enable-multilib --prefix=/opt/gcc The configure runs OK but when building/linking I get the following error: libtool: link: gcc -shared -fPIC -DPIC .libs/lto-plugin.o -l -static-libgcc -static-libstdc++ -static-libgcc ../libiberty/pic/libiberty.a -Wl,-soname -Wl,liblto_plugin.so.0 -o .libs/liblto_plugin.so.0.0.0 /usr/bin/ld: cannot find -l-static-libgcc It seems that some gcc linker options have been but in the wrong place. I have the same mistake with another version of gcc (6.5.0) so the problem seems to be on my side. Would you have any idea about what is wrong with my settings ? Am I missing a dependency ? many thanks in advance for your help Eric
