All you need to know when hacking (modifying) GNU libcharset or when building it off the Git repository. Requirements ============ You will need reasonably recent versions of the build tools: * A C compiler. Such as GNU GCC. + Homepage: https://gcc.gnu.org/ * GNU autoconf + Homepage: https://www.gnu.org/software/autoconf/ * GNU m4 + Homepage: https://www.gnu.org/software/m4/ * Perl + Homepage: https://www.perl.org/ And, of course, the packages listed in the DEPENDENCIES file. Building off the Git repository =============================== Access to the Git repository is described at https://savannah.gnu.org/git/?group=libiconv . After fetching the sources from the Git repository, peek at the comments in autogen.sh, then run "./autogen.sh"; then you can proceed with "./configure" as usual.
