Hello. I want to know how to solve a problem when install gcc without root and offline. I am installing GCC9.4.0, but there are some errors when executing make command, as follows: make[4]: Entering directory `/public/home/jltu/gcc-9.4.0/gcc-9.4.0/lto-plugin' /bin/sh ./libtool --tag=CC --tag=disable-static --mode=compile gcc -DHAVE_CONFIG_H -I. -I../../lto-plugin -I../../ lto-plugin/../include -DHAVE_CONFIG_H -Wall -g -c -o lto-plugin.lo ../../lto-plugin/lto-plugin.c libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../../lto-plugin -I../../lto-plugin/../include -DHAVE_CONFIG_H -Wall -g -c ../../lto-plugin/lto-plugin.c -fPIC -DPIC -o .libs/lto-plugin.o make[4]: Warning: File `../libiberty/pic/libiberty.a' has modification time 8.1 s in the future /bin/sh ./libtool --tag=CC --tag=disable-static --mode=link gcc -Wall -g -Wc,-static-libgcc -module -bindir /public /home/jltu/gcc_build/libexec/gcc/x86_64-pc-linux-gnu/9.4.0 -Xcompiler '-static-libstdc++' -Xcompiler '-static-libg cc' -o liblto_plugin.la -rpath /public/home/jltu/gcc_build/libexec/gcc/x86_64-pc-linux-gnu/9.4.0 lto-plugin.lo -Wc,. ./libiberty/pic/libiberty.a libtool: link: gcc -shared -fPIC -DPIC .libs/lto-plugin.o -static-libgcc -static-libstdc++ -static-libgcc ../lib iberty/pic/libiberty.a -Wl,-soname -Wl,liblto_plugin.so.0 -o .libs/liblto_plugin.so.0.0.0 /usr/bin/ld: /usr/local/lib/gcc/x86_64-pc-linux-gnu/9.4.0/crtbeginS.o: unrecognized relocation (0x2a) in section `.te xt' /usr/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status make[4]: *** [liblto_plugin.la] Error 1 make[4]: Leaving directory `/public/home/jltu/gcc-9.4.0/gcc-9.4.0/lto-plugin' make[3]: *** [all] Error 2 make[3]: Leaving directory `/public/home/jltu/gcc-9.4.0/gcc-9.4.0/lto-plugin' make[2]: *** [all-stage1-lto-plugin] Error 2 make[2]: Leaving directory `/public/home/jltu/gcc-9.4.0/gcc-9.4.0' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/public/home/jltu/gcc-9.4.0/gcc-9.4.0' make: *** [all] Error 2 Regards Jiali Tu
