AC_CHECK_LIB for C++ libraries

[Jan Mikelson]

Hey everyone,

I am currently writing configure.ac and Makefile.am files for a project
I have been working on. The project consists of some C++ shared
libraries and one executable. If they were C libraries I could just use

AC_CHECK_LIB([lib1], [function1])

to check whether the library lib1 is available. This does not work with
C++ libraries. Is there a similar way of doing this for C++ libraries? I
could not find anything helpful online and would appreciate any help!
Thanks a lot!

Cheers

Jan

I've used AC_LINK_IFELSE to check for C++ libs.

Hey Peter,
thanks for your reply, but how exactly do you do this? If you don't have
time to explain it, I would very much appreciate it, if you could point
me to a documentation, where I could read it up. Thank you very much!

Check the autoconf manual ;)

If you need an example the macro '_YAT_CHECK_LIB_YAT' might be useful
