Re: Problems getting dependencies compiled before executable....

Assar

Thanks for the email. I am using Red Hat 8 which means
automake 1.6 and autoconf 2.53.  I spent some time
creating a very *simple* example like you requested.
I'd be very grateful if you looked at it....

In order to show you my problem with _DEPENDENCIES I
intentionally put the executable in src/exec and
the library stuff in src.  Since the executable in
src/exec cannot be built without the library in src
being built *first*, I was hoping build process would
realize this and adjust accordingly.  It didn't and
I got error message I want to fix.

Here are the contents of 2 Makefile.am's that need to be fixed.....

src/Makefile.am:
-----------------------------------------

noinst_LIBRARIES             = libhelperfunctions.a
libhelperfunctions_a_SOURCES = printmessage1.c
                               printmessage1.h
                               printmessage2.c
                               printmessage2.h
                               printmessage3.c
                               printmessage3.h
SUBDIRS                      = exec


src/exec/Makefile.am
-----------------------------------------

bin_PROGRAMS      = main
main_SOURCES      = main.c
main_LDADD        = -lhelperfunctions -lpthread -lm
main_DEPENDENCIES = ../libhelperfunctions.a
main_LDFLAGS      = -L ../
INCLUDES          = -I ../

Here is what happens when I type make at top of source tree
(BTW: $(top_srcdir) = /home/seberino/MAIN/Wb/efe2)....

Making all in src
make[1]: Entering directory `/home/seberino/MAIN/Wb/efe2/src'
Making all in exec

make[2]: *** No rule to make target `../libhelperfunctions.a', needed by

   Why don't you use myprogram_LDADD = libmylibrary.a ?

   I'm not able to reproduce your problem.  Can you tell us what version
   of automake you're running and show us a minimal example that
   shows the problem?
