I'm porting some code from 64 bit Centos to 64 bit Ubuntu. Somehow configure figures out where to put libraries for make install, one of lib, lib32, or lib64. How does it know which to use?

Automake does this for you, whence you look at one and read it you may find that -- here example, I just modded this one just a few ago for Esetroot.c:

I found this line then figured out what it was missing while running make, by reading the errors, it was having an X11 problem, so I opened it up and seen this line, then

Code:

Esetroot: Esetroot.c

        $(CC) $(CFLAGS) $(X11) $(IMLIB_CFLAGS) $(IMLIB_LIBS) $(DEFINES) -o $@ $<

looked up further and found this

Code:

IMLIB_CFLAGS        = $(shell imlib2-config --cflags)

IMLIB_LIBS        = $(shell imlib2-config --libs)

DEFINES                = -DPIXMAP_SUPPORT -DHAVE_UNISTD_H

then just added this to have it inclused -lX11

Code:

X11        = -lX11 

#then added

$(X11) 

#to that other line.

now I have a proper Makefile, and it ran without error.

Code:

IMLIB_CFLAGS        = $(shell imlib2-config --cflags)

IMLIB_LIBS        = $(shell imlib2-config --libs)

DEFINES                = -DPIXMAP_SUPPORT -DHAVE_UNISTD_H

X11        = -lX11



VERSION        = 20030422

INSTALL        = install

PREFIX        = /usr

BINDIR        = $(PREFIX)/bin



SOURCES = Esetroot.c Makefile



all: Esetroot



Esetroot: Esetroot.c

        $(CC) $(CFLAGS) $(X11) $(IMLIB_CFLAGS) $(IMLIB_LIBS) $(DEFINES) -o $@ $<



install: Esetroot

        mkdir -m 755 -p $(INSTALLROOT)$(BINDIR)

        $(INSTALL) -m 755 Esetroot $(INSTALLROOT)$(BINDIR)



clean:

        rm -f Esetroot



distclean: clean

        rm -f *~ \#* Esetroot-*.tar.bz2



tar: distclean

        rm -rf Esetroot-$(VERSION) Esetroot-$(VERSION).tar.bz2

        mkdir Esetroot-$(VERSION)

        cp $(SOURCES) Esetroot-$(VERSION)

        tar cvvfj Esetroot-$(VERSION).tar.bz2 Esetroot-$(VERSION)

        tar cvvfz Esetroot-$(VERSION).tar.gz Esetroot-$(VERSION)

        rm -rf Esetroot-$(VERSION)

in Eterm configure file, that I just installed:

Code:

AC_ARG_ENABLE(sse2, [  --enable-sse2            enable SSE2 assembly routines], [

                  test "x$enableval" = "xyes" && HAVE_SSE2="yes"

              ], [

                  case $host_cpu in

                      x86_64)

                          grep sse2 /proc/cpuinfo >/dev/null 2>&1 && HAVE_SSE2="yes"

                          ;;

                  esac

              ])

it states it, basicly you have to search the file and learn how to read it enouigh to get it to do what you need it to do, errors on the command line help me. BUT it does not put libraries anywhere, it puts the executable in /usr/bin or /bin or where ever it is told to.
