Hello
I have problmes exporting variable names from configure.in:
mylib="-lmylib"
AC_SUBST(mylib)

and then in Makefile.am:
myprog_LDFLAGS=@mylib@

and durring linking myprog i receive error because i got command
g++...@mylib@..., instead of g++...-lmylib...

i can not find mylib in config.status, but i find:
mylib="-lmylib" in config.log

Everything else with automake & autoconf works fine.
Where is my mistake ?

Thanx
Michal

AFAIK you need to refer to the substituted var with $(mylib) in
Makefile.am. So I think this will work:

myprog_LDFLAGS += $(mylib)
