I've stumbled on on an "stupid" issue I've never had to deal with before and I can't seem to get around it (could also be that I'm getting tired...) In my configure.ac I'm using a number of standard AC_LIB_HAVE_LINKFLAGS() calls to allow the end user to configure the library locations. This works as expected. However one of the libraries I need to configure is named "libusb-1.0.so" but if I use "usb-1.0" as the library name in the call to the macro this will the generate an illegal variable name that automake chokes on. SRC/MAKEFILE.AM:19: WARNING: LIBUSB-1.0: NON-POSIX VARIABLE NAME Renaming the name of the library is no-solution since I cannot control 3:rd party library installation. Have anyone else had to deal with this? (I guess there is a simple solution that I just fail to see but no matter of what more and more bizarre quoting I tried with I cannot get automake to accept the name) --Johan (I'm using autoconf 2.69 / automake 1.12.1) _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
