I thought in this thread we were only talking about its build system,
not the source code or Singular's quality in general.
I cannot resist to give some excerpts from just src/Singular/
Makefile.in:
##
## various programs
##
@SET_MAKE@
CC = @CC@
LD = @LD@
CXX = @CXX@
LEX = sh flexer.sh
PERL = @PERL@
BISON = bison
INSTALL = @INSTALL@
INSTALL_PROGRAM = @INSTALL_PROGRAM@
INSTALL_DATA = @INSTALL_DATA@
MKINSTALLDIRS = ./mkinstalldirs
LN_S = @LN_S@
...
SOURCES=${CSOURCES} ${CXXSOURCES} \
grammar.y scanner.l libparse.l \
utils.cc utils.h \
tesths.cc mpsr_Tok.cc claptmpl.cc
...
##
## Build Targets
##
.l.cc:
@if test -r scanner.cc; then \
touch scanner.cc ;\
elif test "x${LEX}" = x; then \
echo Error: no lex given, could not rebuilt scanner.cc;\
exit 1; \
fi
${LEX} -s -I -t $< > scanner.cc.lmp
cp scanner.cc.lmp scanner.cc
.y.cc:
@if test -r grammar.cc; then \
touch grammar.cc ;\
else \
if test "x${BISON}" = x; then \
echo Error: no bison given, could not rebuilt grammar.cc;\
exit 1; \
fi;\
${BISON} -d -t -o grammar.cc $<;\
chmod +x testgh;\
./testgh;\
fi
Note that these are all from the same file. You could also take a look
at flexer.sh...
