Very good point Jonathan.... >You can install GCC 4.7 first, as that can be built using only a C >compiler. Then use GCC 4.7 to build GCC 5.2 Ok. This is what I´ve decided to do... In real a good path to solve my problem. I´ve now downloaded and tried to compile the Gcc 4.7.0 version and now seens that I´m having problems with link libraries: make[3]: Entering directory `/home/ftp/pub/gcc-build/gcc' gcc -g -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -o cc1 c-lang.o c-family/stub-objc.o attribs.o c-errors.o c-decl.o c-typeck.o c-convert.o c-aux-info.o c-objc-common.o c-parser.o tree-mudflap.o c-family/c-common.o c-family/c-cppbuiltin.o c-family/c-dump.o c-family/c-format.o c-family/c-gimplify.o c-family/c-lex.o c-family/c-omp.o c-family/c-opts.o c-family/c-pch.o c-family/c-ppoutput.o c-family/c-pragma.o c-family/c-pretty-print.o c-family/c-semantics.o c-family/c-ada-spec.o i386-c.o default-c.o \ cc1-checksum.o main.o tree-browser.o libbackend.a libcommon-target.a libcommon.a ../libcpp/libcpp.a ../libdecnumber/libdecnumber.a libcommon.a ../libcpp/libcpp.a ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -lmpc -lmpfr -lgmp -ldl -lz /usr/bin/ld: cannot find -lz collect2: ld returned 1 exit status make[3]: *** [cc1] Error 1 make[3]: Leaving directory `/home/ftp/pub/gcc-build/gcc' make[2]: *** [all-stage1-gcc] Error 2 make[2]: Leaving directory `/home/ftp/pub/gcc-build' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/home/ftp/pub/gcc-build' make: *** [all] Error 2 I need help to move this step foward and be ready to install the 5.2 version.
