I have a header file avcall.h which collects the results of autoconf tests,
so it is mentioned in AC_CONFIG_HEADERS.
I also want it to define the package version cpp macro, so I added
#if !defined(LIBFFCALL_VERSION)
# define LIBFFCALL_VERSION @PACKAGE_VERSION@
#endif
to it (there are several such headers, each has these 3 lines).
however, configure did not substitute @PACKAGE_VERSION@.
thus I added avcall.h to AC_CONFIG_FILES.
nothing changed, no warning or error on configure generation.
so I added this to configure.in:
AC_CONFIG_HEADERS([avcall.h],
[sed "s/@PACKAGE_VERSION@/${PACKAGE_VERSION}/" avcall.h > tmp
mv -f tmp avcall.h])
now @PACKAGE_VERSION@ is removed, nothing is inserted.
That is because the sed command is executed by config.status where
PACKAGE_VERSION not undefined. You should try
AC_CONFIG_HEADERS([avcall.h],
[sed "s/@PACKAGE_VERSION@/$my_PACKAGE_VERSION/" avcall.h > tmp
mv -f tmp avcall.h],
[my_PACKAGE_VERSION=$PACKAGE_VERSION])
(the changed variable name is to avoid conflicts, may not be needed).
