Without this, a "make all-sim" without the equivalent of libreadline-dev installed on the build system, won't properly pick up the in-tree readline build, and you'll see: mkdir -p -- ./sim Configuring in ./sim configure: creating cache ./config.cache checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking target system type... cris-axis-elf checking for x86_64-pc-linux-gnu-gcc... gcc checking whether the C compiler works... yes ... checking for library containing tgetent... -ltermcap checking for readline in -lreadline... no configure: error: the required "readline" library is missing make[1]: *** [Makefile:11188: configure-sim] Error 1 make[1]: Leaving directory '/home/hp/sim/b' The sim dependency on readline is apparently (nominally) valid as there's a readline call in sim/erc32/sis.c. 2022-02-21 Hans-Peter Nilsson <hp@axis.com> * Makefile.def (dependencies): Make configure-sim depend on all-readline. * Makefile.in: Regenerate.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
