Less error-prone for others if you create a Diff of your Makefile changes against the original local file.
> diff -U original changed for universal format, which the Patch tool can use. Then post with Subject: [PATCH] Makefile. I don’t use Emacs. Diff and Patch automatically determine the lines that change.

There where multiple definitions for yychar, yylval etc. and genbc was not compiled. I have added a linker flag in the generated makefile after the configure script was executed. It is a direct editing of the resulting makefile and not the configure script files (I have not tried using LDFLAGS with configure script, being afraid it will be applied to all programs). I don't understand very well how autotools work. But with this modification I was able to build a "gst" program, and running 'make check' seem to give adequate results, but not 100% (it will be left for another session). My steps after cloning the gnu-smalltalk git package 1) autoreconf -vif 2) ./configure 3) and then, the really ugly hack: in the libgst/Makefile add -Wl,allow-multiple-definition to compile genbc. Theline will look like: genbc$(EXEEXT): $(genbc_OBJECTS) $(genbc_DEPENDENCIES) $(EXTRA_genbc_DEPENDENCIES) @rm -f genbc$(EXEEXT) $(AM_V_CCLD)$(LINK) -Wl,-allow-multiple-definition $(genbc_OBJECTS) $(genbc_LDADD) $(LIBS) It enabled me to have a working "gst". If the compilation request is done through emacs, following errors will point directly to the file and line where change must be inserted. Hope it help, and if there is a less "hacky" way to have a running program it would be nicer than this solution. Jean-Marc Farinas
